CSP/µBGA Test & Burn-In Socket for Devices up to 55mm Square

For Test & Burn-In of CSP, µBGA, DSP, LGA, SRAM, DRAM, and Flash Devices. Consult Factory for QFP applications.
Any device on 0.40mm pitch or larger.
4-point Crown insures “scrub” on solder oxides.
Single-point Probes available for small land area contact pads.
Signal path during test only 0.077 [1.92]
Socket is easily mounted and removed to and from the Burn-in Board (BIB) with Solderless Pressure-mount Compression Spring Probes, accurately located with two molded plastic Alignment Pins and mounted with four Stainless Steel screws.
Gold over Nickel-plated Compression Spring Probes leave small witness marks on the device’s solder balls.
Standard molded socket format can accommodate any device package of 55mm square or smaller.
Spring-loaded, cam-actuated Pressure Pad applies proper force against the device after the lid is closed, latched and the cam is rotated to it’s detented location. Reversing the cam removes the force applied to the device prior to unlatching the spring-loaded lid to it’s upright position.
