LGA vertical compression connectors; board-board or stacking uses

April 28, 2015 // By Graham Prophet
Distributor Astute Electronics has Airborn’s RZ Series of high-density LGA solderless open-field connectors which employs a one-piece contact system, with 1.27mm contact spacing. The RZ Series features a patented Z-axis contact system and is designed to be compressed under pressure between parallel PCBs or between the PCB and other electronic components.

These vertical surface-mount PCB compression connectors are presented as ultra-reliable, thanks to the one-piece contact system; the beryllium copper contacts use gold over nickel finish and the products are available in contact sizes 20 – 175 (2 - 7 rows and 10 – 25 columns). Available heights are 2.54 mm to 8.89 mm. Electrical characteristics include current rating of 0.5A and typical contact resistance of 25 milliohms, depending on contact height. Insulation resistance is 5000 mega ohms minimum at 100 VDC.
