Brand new
R
U Raspberry Pi B+ board
The new Raspberry Pi B+, now available from element14,
is the first major update to the popular credit-card sized
computer. It adds connectivity and power features to enable bigger and better projects.
The new board, which marks the first significant change
to the multi-million selling credit card-sized computer, is
priced at just $38. The new board offers more sensors and
accessories than before, enabling users to build bigger and
better projects.
Advanced power management and enhanced connectivity make it possible to power four USB accessories, such
as 2.5 inch hard drive, through the device. Up to 1.2A can
be delivered to the USB ports to connect power-hungry
devices and accessories without needing mains power or
an external USB hub.
Featuring a 40-pin extended GPIO interface, even more
sensors, connectors and expansion boards can be added to
the board, allowing users to increase the complexity of their
Raspberry Pi projects. The first 26 pins remain identical
to the original Raspberry Pi Model B for 100% backward
compatibility.
The Raspberry Pi B+ is based on the same Broadcom
BCM2835 Chipset and 512MB of RAM as the previous
model. It is powered by micro USB with AV connections
through either HDMI or a new four-pole connector replacing the existing analog audio and composite video ports.
The SD card slot has been replaced with a micro-SD
slot, tidying up the board design and helping to protect
the card from damage.
The B+ board also now uses less power (600mA) than
the Model B Board (750mA) when running.
Since its launch in February 2012 over three million
Raspberry Pi boards have been sold and the element14
Community has become one of the leading websites for
discussion and collaboration around Raspberry Pi projects
and developments.
With over 250,000 registered users the element14 Community is the largest online community for design engineers
to share ideas, knowledge and solve challenges.

PCB Designing and
Manufacturing Tips –
straight from the horse’s mouth!
Most decent electronics engineers can design a half-decent Printed Circuit
Board. But few understand what happens when they send their PCB file
off to the manufacturer. There are many traps that most wouldn’t know
about, let alone consider. We asked Tejas Shah, the Business Development
Manager of major Australian/New Zealand PCB supplier QualiEco Circuits,
to give us some tips (with examples) from the manufacturing side.
P
CB designers are often confused as to
what manufacturers need to turn their
masterpiece into reality. Without knowing the requirements of the manufacturer,
mistakes are often made – and mistakes are
always costly.
The manufacturer has great skill in interpreting what the designer actually wants
but sometimes, they are left scratching their
heads.
The adage “impossibilities done immediately, miracles take a little longer” springs
to mind!
This article explains some basic PCB
design/manufacturing concepts and ideas
which will help expand your knowledge in
not only PCB design but how your choices
affect cost of efficiently manufacturing PCBs.
Shielding or open tracks
raised if the gap is smaller.
If you use shielding tracks or open tracks
for antennas, please mention this clearly.
CAM engineers normally catch such tracks
and may result in a query.
Tracks too close to cut lines
If any of your copper area or tracks are
close to cut lines, the CAM engineer might
ask your permission to shave copper to avoid
cutting into it during routing or v-cut.
If you allow 0.3mm gap for routing and 0.4-0.5mm gap for v-cut, it
would be considered a safe distance.
How to design a
manufacturer-friendly PCB
Every manufacturer has a CAD/CAM department, where your PCB design is checked
thoroughly before it goes in final production.
An EQ (Engineering Query) may be raised
if the CAM engineer has any doubts. This
process not only increases manufacturing
lead time but can create confusion if there
are many queries to resolve.
To-and-fro communication may also annoy you if queries are not handled professionally by the CAM engineer.
The million dollar question is – Is it really
possible to design query-free PCBs?
Yes, it is possible, if some simple rules are
followed throughout the design phase. A few
examples that I am going to discuss here will
certainly help you achieve this.
siliconchip.com.au
Multilayer PCB design
Inter-track gaps
If you are designing a multilayer
PCB, please provide a detailed layer
stack-up, if you have any special requirements . Remember – there is more than
You should

to 0.076mm)

one way to build a
structure and every
manufacturer can prepare the layer stack up
differently, based on the stock
they carry for prepreg and core.
Plated holes
If your design file requires any holes to be
plated, please provide copper pads on both
sides. If the CAM engineer leaves the design
unchanged, there could be plating issues, so
you will most likely be asked for permission
to add copper pad or, if you change your
mind to non-plated hole, to isolate copper.
Surface finish considerations
You need to choose the surface finish
very carefully. HASL is a default finish for
most PCB manufacturers. If your product
requires RoHS compliance, you can choose
either lead-free HASL or immersion silver/
gold/tin finish.
As a rule of thumb, if the minimum pitch
of your SMD components is 0.5mm or lower,
it is strongly advisable to choose immersion
silver/gold/tin finish.
A word of caution: immersion silver finish
PCBs need to be used within 2.5 to 3 months
of the date of manufacturing. Silver finish
demands great care in packing and storage.
Some interesting facts –
Did you know this?
1. Rigid PCBs can be made as
thin as 0.25mm. It means you can
use it like a flexible PCB in certain
cases. It is not a perfect replacement
but if your aim is only to achieve little
bit of flexibility, this is not a bad idea!
Technical specifications
Mating PCBs
If your project requires one PCB to be
inserted in another PCB (ie, mating PCBs),
always consider both laminate thickness
tolerance (±10%) and routing tolerance
(±0.1 to 0.2mm) before designing slots
It is best practice to provide basic technical specifications in one of your layers.
Some manufacturers do not send a detailed
technical confirmation report and assume
lot of technical parameters to their own
standard, which may not be same as your
expectations.
Communication is extremely critical for
PCB manufacturing and one little misunderstanding could cost a fortune.
What makes a PCB expensive?
If you know what specifications are standard, you can make the maximum out of your
design. Unfortunately, specifications differ
from manufacturer to manufacturer – there
is no “standard” specification.
The table below shows what QualiEco
Circuits considers standard/non-standard
features. Standard features result in the
lowest cost PCBs. Non-standard features
can of course be achieved but will result in
a more expensive board.
2. If you are designing a panel (ie
array) of PCBs for pick and place
assembly, you can get away with
panel strip on only two longer sides
of the panel by wisely placing break
off tabs. Tab and hole sizes and
positions are extremely important.
You can save up to 20% of unit
price by intelligently designing your
panel structure. For high volume
manufacturing, it is indeed a huge
saving!
A smart PCB manufacturer can
study your component reference to
judge required mechanical strength
of the panel before suggesting an
optimum panel structure.

Lintek has 27 years experience in
Manufacturing PCBs in Australia
T
he PCB manufacturing industry has
certainly changed over Lintek’s 27
year involvement. To survive in this
industry is not easy; your customer service,
quality and knowhow must be second to
none – local clients know that they are
paying a premium and they don’t need too
many excuses to move offshore.
The ‘heavyweights’ of the 1980s and 90s
have all but disappeared – or have moved
higher up the food chain where they can
value-add by providing turnkey solutions.
For Lintek, a 100% Australian manufacturer, the trick has been to try to stay
nimble, dynamic and quick to respond.
Developing good customer relationships
and educating designers about the process
complexities we encounter is paramount to
our survival. They find that the best clients
‘Design for manufacture’ and are willing to
modify their designs if it improves quality,
consistency and price.
There is always a compromise between
price and performance as higher quality dielectrics cost more, can be more difficult to
process and manufacturing times are longer
due to tighter process controls. Having an
in-depth understanding of material behaviour
over many years of processing exotic laminates gives their engineers the confidence
to take on the most complicated projects,
many of which their clients find difficult to
source anywhere else. Knowing your ‘sweet
spot’ is extremely important when taking on
the rest of the world – having a technological
advantage certainly helps.
R&D is extremely important to Lintek as it
helps the company stay in touch with industry
trends. The continuous miniaturisation of
parts can leave you falling behind the pack
very quickly and new opportunities become
more difficult to find.
Driven by industry demands, Lintek is
currently developing a number of new capabilities. One of these is to develop ‘via-in-pad’
technology around vacuum metalisation. This
will enable the formation of copper-filled
‘microvias’ laser-drilled down to copper
capture pads on multilayer PCB stacks. The
copper-filled vias will simplify the assembly
of BGA devices down to 0.4mm pitch and will
be a first for Australia.
LINTEK
To help develop these capabilities,
Lintek has been successful in receiving
funding for this project through DMO under the PICIP (Priority Industry Capability
Innovation Program).
The successful application for funding
is testament to the critical role they play
in supporting key defence suppliers. They
are also working with the team from DIIC
(Defence Industry Innovation Centre) to
take business to the next level. Their understanding of business and government
assistance available, along with training
and awareness programs, has been a
great help. Since their involvement with
DIIC Lintek have joined SCIP (Sustainable Continuous Improvement Program
or SC21), have become more active in
the GSC (Global Supply Chain) and are
working on implementing ‘lean management’ practices.
Finally, Lintek would also like to thank
Andrew Pollock and his team at the
SMCBA, they do a great job and offer
an invaluable service to the Australian
electronics industry.
PRINTED CIRCUITS
TOMORROWS PRINTED CIRCUITS TODAY
Incorporated in 1986, Lintek is a quality Australian
manufacturer of Microwave printed circuit boards. Lintek’s
patented High Vacuum Deposition process enables the
production of extremely accurate microwave circuit features
on a wide variety of conventional and exotic substrates including precision milled metal backed carriers. High bond
strength to PTFE and minimal side wall undercut are two
key features synonymous to Lintek’s process. This innovative
process allows Lintek to provide PCB’s for the latest high
frequency commercial or military designs as well as the
standard FR4 Single sided, DSPTH and Multilayer circuit
boards.
Unrivalled Accuracy
i) Lintek’s process requires significantly less etching to
remove a very thin 1-2 micron vacuum deposited copper
seed layer instead of the standard 18 microns copper base
layer used on Electroless copper processes, thus eliminating
undercut and ensuring the repeatability of:a. very fine track and spaces.
b. accurate copper features and filters.
c. near perfect side wall resolution.
d. superb impedance control.
Repeatability of
Fine track and spaces.
e. High bond strength to exotic substrates
ii) Plated through holes are stronger and more reliable due to
the same amount of copper being deposited in the hole barrel
as on the surface. This is particularly important on PTFE
materials, which have a large thermal expansion in the Z
direction.
iii) The elimination of Sodium etching that is normally used
on PTFE materials, this saves time, cost and our environment.

You may not realise it but many, if not most, PCBs these days have a
conformal coating. But what is that – and what is its purpose?
C
onformal coatings are thin
polymeric films which cover and
protect solder joints, the leads of
electronic components, exposed tracks
and other metallized areas on PCBs
from corrosion.
Humidity, condensation, salt-spray,
corrosive gases or a combination of all of
these activate the start of the corrosion
process, which can be accelerated by
residues from soldering and other assembly processes prior to coating.
There are many conformal coating
chemistries available and each have their
own benefits and drawbacks. Conformal
Coatings are available in solvent-based,
water-based and 100% active materials
(nearly everything that is applied in liquid
form is converted into solid protective
coating), as well as vapour deposited
coatings.In these, gases are mixed in a
vacuum, where they are polymerized and
deposited onto the surface of the PCB
as a protective film.
The primary benefits and disadvantages of the different chemistries available
can be summarised as follows:
Coating Standards
Most conformal coatings are either
qualified to MIL-I-46058C or meet the
Coating Type
Solvent-Based Acrylic
Solvent-Based Urethane
requirements of the closely related
IPC-CC-830B specifications. In addition
they may be recognised by Underwriters
Laboratories, either as a permanent coating, in which case the flammability of the
coating is assessed to UL94V0, or as a
conformal coating, where the electrical
properties will be assessed as part of
the UL746E standard.
The actual protective capability of the
coating in the end use environment is of
greatest concern to the user.
Corrosion
Corrosion is a complicated electrochemical process with a variety of
potential mechanisms and causes, well
beyond the scope of this article. However,
in the vast majority of cases, there are
three requirements that must be fulfilled
in order for corrosion to proceed, as
shown above right.
In order to prevent the possibility of
corrosion, it is necessary to remove one
of the pre-requisite conditions.
The choice of metals is limited to
those used in the solder and solder finish
chemistries (which are often dissimilar)
and there will always be areas of potential
difference in an operating circuit. Cleaning can help remove ionic species, but
In order to obtain the maximum levels
of protection available from the particular chemistry, two key criteria must be
fulfilled:
1. The coating must display excellent
adhesion to the substrate in question
under both dry and highly humid or damp
conditions to prevent delamination.
2. The coating must fully cover the
exposed metal surfaces in order to be
effective as a moisture barrier.
Thus, selecting the ‘correct’ conformal
coating is merely the first stage in the
protective process. Perhaps of greater
importance is the preparation prior to
coating (eg cleaning) and the actual ap-

cannot prevent the re-deposition of ionic
species from the operating environment.
Conformal Coatings help prevent the
formation of electrolytic solutions by acting as moisture barriers. The coating must
have good adhesion to the substrate to
prevent delamination. Once the coating
is delaminated, moisture can eventually collect in this ‘pocket’ and form an
electrolytic solution with any pre-existing
ionic contamination. This is the reason
that cleaning prior to conformal coating
is recommended.

plication process itself. Conformal coating materials are not intelligent; they go
where they are placed.
Most materials will tend to slump away
from sharp component edges, leads
and solder joints due to gravity, and this
behaviour can be made worse by longer
drying times and also by baking, if the
initial viscosity drop is greater than the
increase due to solvent evaporation. It is
also extremely difficult to achieve good
coating coverage on the backsides of
leads. Understanding and controlling this
behaviour, and its effect on the conformal
coating coverage, will be key to the performance of coated assemblies operating
in harsh environments.
Therefore, the process by which the
conformal coatings are applied, and the
workmanship and control within that
process, will have the greatest influence
on the success or failure of that particular
coated assembly.
Conclusion
Understanding that the conformal
coating can only protect the surfaces to
which it is applied with perfect coverage,
and that voids, bubbles and cracks in
the coating are likely to present a highprobability corrosion initiation site, is a
major step towards developing a reliable
product.
Choosing a suitable conformal coating
chemistry that can withstand the expected environmental challenges whilst still

yielding acceptable performance levels
is the next step.
But ensuring that the material can be
combined with an application process
that gives a suitable level of defect-free
coverage, is consistent, repeatable and
yields the required levels of performance
is the ultimate step towards ensuring a
high-reliability product.

Need solder paste stencils?
Mastercut Technologies now
manufactures DEK Stencils in Australia
Mastercut Technologies is now
licensed by DEK Singapore to manufacture DEK VectorGuard stencils, as
well as supply new frames.
The DEK VectorGuard Framing System is an automatic tensioning system
for solder paste stencils. It eliminates
the need for complex alignment procedures and is independent of traditional
pneumatic assistance processes.
The stencils feature an extruded
aluminium guard, which is securely
attached to the edge of the foil using
interlocking plastic corners. Providing
accurate and automatic tensioning, it
takes only seconds to mount a foil into
the VectorGuard frame.
Mastercut will be launching the
DEK VectorGuard Framing System in
Australia, at Electronex in September
this year. This comes after the launch
of the LPKF ZelFlex System in 2013,
also by Mastercut.
68 Silicon Chip
With over 20 years experience,
Mastercut is the only solder
paste stencil manufacturer
in Australasia and pride
themselves on providing
the highest quality stencils
and fast turnaround.
Mastercut Technologies Managing Director,
Mr Jim Cove, explained,
“All of our stencil customers demand guaranteed high precision and fast delivery, in order to meet
their forever tight deadlines”.
“We use German laser cutting technology which has been specifically
designed to manufacture stainless
steel SMD solder paste and adhesive
stencils, for a consistent high quality
cut and excellent paste release”, Mr
Cove Said.
Both VectorGuard and ZelFlex systems provide superior tensioning and
result in a reduction of stencil storage
space by up to 75% compared to traditional mesh mounted stencils, as well
as being more cost effective to freight.
Visit Mastercut at stand A15 at Electronex in Sydney, 10-11th September
to see both the VectorGuard and ZelFlex frames first hand.
Alternatively, you can contact Mastercut Technologies at 22 Leda Drive,
Burleigh Heads QLD 4220, Tel. (07)

Need prototype PC boards in a hurry?
Mill them yourself!
Satcam’s range of Quick Circuit machines will take your computer
PCB design and turn it into a finished prototype faster than it takes
a courier to deliver one from a bureau!
Gone are the days of messy (and dangerous!) chemicals, film
negatives or positives, a light source and then the clean-up – not
to mention the tedious task of drilling all those holes.
The Quick Circuit takes a blank piece of PCB material, reads the
design (from the vast majority of PCB layout packages) and then
goes to work milling, or if you like grinding, off the areas where
you don’t want copper – the inter-track spaces and even the holes.
Change the bit and even those holes are drilled for you. It’s fascinating to watch the QuickCircuit move over the blank board – but
you don’t even have to stick around watching because the process
is largely automatic. And it can even produce double-sided boards.
The result is a finished PCB ready for component placement
and soldering – it really is that easy.
What about strange shaped boards, cutouts, notches and fitted
shapes for components? No worries – again, with a suitable bit,
the QuickCut will cut any shape required. It will even tell you when
the bit needs changing to achieve these.
And how long?
A typical 300 x 300mm single-sided board will take about an
hour to produce. Compare that with traditional (photo) methods
which don’t have the flexibility of the Quick Circuit Mill.
If you need prototype boards in a hurry, there is only one way
to make them: mill them, with a Quick Circuit from Satcam.
Visit Satcam on www.satcam.com.au or call (02) 9807 7081.

Keysight Technologies’
New U5855A Handheld
Thermal Imager
With the shift toward predictive maintenance, the
U5855A TrueIR thermal imager allows engineers to
safely and efficiently identify potential faults without
shutting down the systems or disrupting the productivity
of an industrial plant.
The U5855A comes with Fine Resolution capability,
which enhances the quality of thermal images by reconstructing the image based on multiple continuously captured infrared frames. This allows the U5855A to achieve
an effective image resolution of 320 x 240 pixels from a
160 x 120 pixel detector.
With this feature, the U5855A provides four times more
resolution than typical 160 x 120 thermal imagers. Together
with a 4x digital zoom, the U5855A reveals finer details,
especially when inspecting small cracks on industrial
pipelines even from a distance.
The U5855A’s light and ergonomic design allows engineers to comfortably use the thermal imager for longer
periods of time and operate it single-handedly in tight
HAMEG Instruments now carry the
Rohde & Schwarz name
Test and Measurement products from Rohde & Schwarz
subsidiary HAMEG Instruments are now marketed under
the Rohde & Schwarz logo.
The well-known brand name will help improve the
international position of the economical, general-purpose
T&M instruments from HAMEG, which are part of the joint
Value Instruments portfolio.
Previously, all HAMEG products had a dual logo that included the company names Rohde & Schwarz and HAMEG.
According to Roland Steffen, Executive Vice President and
Head of the Test and Measurement Division, “In recent
years, HAMEG has grown rapidly in Europe. Now we want
to expand this growth to other regions. The best way for
this to succeed is with the Rohde & Schwarz brand, which
enjoys an outstanding reputation worldwide. This strategy
clearly sets us apart from other suppliers.”
Using the Rohde & Schwarz logo is also the logical continuation of the Value Instruments initiative, where the two
companies’ portfolios of reliable precision instruments in
the entry-level price segment are marketed together under
the Value Instruments label.
André Vander Stichelen, Managing Director of HAMEG
Instruments, elaborates, “By changing the logo, we want
to underscore the common bond between the two companies. The strategic focus of HAMEG will not change. We
will continue to offer affordable, optimum performance
T&M equipment.”
The company HAMEG Instruments GmbH will continue
to operate as an independent company under the umbrella
of the Rohde & Schwarz group of companies. The two sites
in Mainhausen and Chemnitz will be expanded.
