“For decades the spring-loaded probe aka pogo-style pin has delivered excellent mechanical and electrical performance in a highly compliant contact,” said the Texas firm. “However, this often came at a high cost given that each pin is constructed of three or four discreet parts manufactured in a less-than-fully-automated process.
Like pogo-pins, the new design, dubbed the H-Pin, can be used at sub-mm pitches.
The firm claims same mechanical, electrical and thermal performance pogo-pins with a working length compliance of up to 1mm, a flat spring rate, operation at up to 15GHz with -1.0dB loss, 4A capability, and 200°C maximum temperature. Mounting pitch can be as low as 0.2mm.
“Although there are a few design tweaks, the real departure is in the manner in which complete pin assemblies are manufactured using a high volume BeCu stamping process, a 100% automated, high speed assembly, and inspection process that can produce up to 400 pins per minute,” said Plastronics, which has been making spring-loaded probe pins for burn-in, humidity and failure analysis for 40 years.
As well as test, the pins can be used for for board-to-board connection in telecoms, automation, medical, aerospace, and military applications said Plastronics. “These connectors create a one-sided connector that is mounted against pads on the PCB.”
