Ultra-low profile board-to-board compression contacts

Impervious to even extreme shock and vibration, the new 70-9155 ULP board-to-board compression contacts provide a rugged and reliable compression connection to the mating board and can be surface mounted to any position on a PCB, significantly enhancing design flexibility with regard to both layout and output voltage, which directly corresponds to the distance between contacts. The individual ULP contacts are also capable of reducing both the size and cost of end-designs in a broad range of harsh environment applications, including: portable and handheld industrial devices, board-to-board power and signal connections, and ground connections between PCBs or housings.

Tom Anderson, Product Manager at AVX, commented: “Achieving full connector performance functionality at the individual contact level is no easy task. That AVX’s unique new 70-9155 ultra low profile board-to-board compression contact is robust enough to survive handling and mating in harsh environment applications without the guidance and protection of a plastic insulator is a direct result of the company’s more than 20 years of experience designing, honing, and perfecting single piece compression contacts."

Packaged on tape and reel for automated SMT placement, AVX’s new 70-9155 Series ULP board-to-board compression contacts are rated for 3A and -40°C to +125°C; voltage ratings for the individual contacts are dependent upon their placement. Currently comprised of two contacts, the 70-9155 Series is available with nominal operating heights of 1.0mm and 1.5mm and with contact operating height ranges of 0.75-1.25mm and 1.25-1.75mm, respectively. Designed for high reliability performance up to 1,000 cycles, the series features beryllium copper contacts with nickel under plates, gold on the nose, and tin on the tails. To satisfy the environmental and expected lifetime requirements of various end products, 70-9155 contacts are also available with three gold plating options: 0.1µm for 50 cycles (standard), 0.4 µm for 500 cycles, and 0.8 µm for 1,000 cycles. Lead time for the series is nine weeks.
