Infineon Technologies is testing a biodegradable PCB material based on natural fibres in demo and evaluation boards. The substrate, branded Soluboard, is from UK start-up Jiva Materials, which claims that it would result in a 60% reduction in carbon emissions compared with FR-4, saving 10.5kg of carbon and 620g of plastic per square meter of PCB. Made from undisclosed natural fibres ...

Connector maker Harwin has teamed up with TraceParts to offer 3D models of its connectors as well as models of its board-level EMC shielding and PCB hardware. “Models are available in all current file formats for engineers to integrate directly into their CAD system,” according to Portsmouth UK based Harwin. The same deal has put Harwin’s parts onto TrustedParts, a ...

CUI Devices has added 20 x 20 x 6mm and 35 x 35 x 7mm fans to its thermal management products. Bearing options include sleeve, ball and the company’s own magnetic (-V suffix) and enhanced sleeve (-C or -CF). 20 x 20 types range from 0.33 to 1.56cfm and 0.02 to 0.24inch of water pressure. 30 x 30 x 7 ...

Chomerics has announced a thermal gap filler pad material with a conductivity of 8.3W/m.K and 40 Shore 00 hardness. “With the highest available thermal conductivity in its product family, ‘PAD 80’ maintains low compression forces and conformability between mating surfaces,” said Chomerics. “Very low compression force means the product will deflect under assembly pressure, minimising stress on components, soldered joints ...

Pickering Electronics has announced 125°C versions of its 104 series high-voltage reed relays. 104HT relays will be available in a 1 Form A configuration (SPST NO) rated to stand-off 4kV. Full data has yet to be unveiled but, using the original (-20 to +85ºC) 4kV 104 relays as a guide, switching capacity is likely to be 1kVdc at 25W, and ...

ABB is focussing on companies exporting heavy equipment to the US with a series of long-life motors built to meet NEMA requirements. Constructed with NEMA 5800 (368.5mm, 14.5inch shaft height) frames, the induction motors can deliver up to 1,750 horse power. They have “high-strength welded steel frame construction usually reserved for larger motors reduces stress and vibration to ensure a ...

Delo has created a high-temperature adhesive for electric motor components. “HT2990 is designed for use in multiple processes, including magnet bonding and magnet stacking in electric motor manufacturing,” according to the company. This is a dual-cure adhesive: Heat is the main way that it is cured, but accessible parts of its can also be cured in 10s using light (400nm ...

Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style), allowing the user to pick devices with the appropriate step-count per revolution, with or without a push switch. “The [pre-soldered] on-board microcontroller is programmed with ...

Omron is aiming at electric vehicle chargers and solar photovoltaic installations by adding a low contact resistance model to its two-pole single-throw G7L-2A-X series of PCB-mount relays. G7L-2A-X-SI has 10mΩ maximum contact resistance, compared with 100mΩ maximum for existing members of the family. Nominal rating is 30A at 600Vdc, or 25A at 1000Vdc (but see below). Versions with 12V (190mA ...

Samsung is set to extended its ‘Self-Repair’ programme for phones to Europe, having launched it in the US last year and recently taken it to Korea. “Galaxy customers who wish to make their own device repairs can access the tools they need, including repair kits and genuine Samsung parts,” said the company. “The program supports repairs to Galaxy S20, S21 ...
