PRODUCT SHOWCASE RayMing does much more than manufacture PCBs – they assemble them too! RayMing is a PCB Manufacturer with ten year’s exerience. In addition, RayMing can also provide one-stop PCB manufacturing and PCB assembly. Based in Shenzen, China, RayMing has two types of PCB assembly services: full and partial turn-key services. Full Turn-Key covers all aspects of PCB fabrication and assembly, from manufacture of PCBs, parts procurement, quality inspections through to final PCB assembly. In Partial Turn-Key, the customer is responsible for supplying the PCBs and a partial list of parts. RayMing will order the remaining parts and perform the assembly according to the customer’s requirements. They can also kit the parts. RayMing Technology uses a variety of testing methodologies to ensure the assembled boards are functional prior to shipping, with ISO 9001 Quality Certification. 4-digit displays have many uses 400GbE OSFP I/O connectors now at Mouser Manufactured by Akytec, the ITP11 4-digit, 7-segment LED display is designed to be connected to any pressure, temperature or other transmitter with a 4-20mA output. Measuring 24 x 48mm, it requires no auxiliary power, being supplied directly from the current loop. The measured values are scalable and there is also an optional square root function for flow applications. Unlike displays from other manufacturers that require a rectangular hole cut in the cabinet or enclosure to mount it, the ITP11’s compact, standardised design fits into a standard 22.5mm borehole for signal lamps. This provides quick and easy installation and many displays can be accommodated in a control cabinet door or on a panel. The display is available in red or green and it can be programmed to flash if the level reaches an alarm state. Other LED display models from Akytec feature voltage, RTD, thermocouple and Modbus inputs. Mouser Electronics, Inc., is now stocking OSFP input/output (I/O) connectors from TE Connectivity (TE). TE’s next-generation octal small form-factor pluggable (OSFP) connectors are designed for maximum thermal and electrical performance in data center applications. TE’s OSFP connectors deliver 400 Gigabit Ethernet (400GbE) speeds over eight electrical lanes to support equipment that operates at up to 56 gigabits per second (Gbps) PAM-4 and 28Gbps NRZ. The SMT connectors offer a 60-position interface with a tworow design on a proven 0.6mm contact pitch. Offering low PCB cost and noise, the SMT connectors are belly-to-belly capable with inground alignment. OSFP cage assemblies feature a flat rock PCB assembly and support 1×1 and 1×4 single-port and multi-port applications.

Microchip Technology Inc., via its Microsemi Corporation subsidiary, has introduced AcuEdge ZLK38AVS Development Kit for Amazon Alexa Voice Service (AVS) to help designers build devices with one-mic handsfree and two (180° linear) or three-mic (180° linear or 360° triangular) far-field configurations qualified by Amazon. It includes the ZL38063 audio processor which connects directly to a Raspberry Pi 3B with plastics and mounting hardware to simulate a typical, recommended end-application mic-speaker arrangement. The field-programmable, field-upgradable solution features signal processing algorithms proven to improve both local trigger detection performance and cloud speech recognition accuracy. The multi-micro-phone configurations include Direction of Arrival (DOA) estimation to indicate where the primary voice sound SC source is located.
