High-Frequency Center Probe™ Test Socket for Devices up to 13mm Square

For Test & Dynamic Burn-In of CSP, µBGA, DSP, LGA, SRAM, DRAM and Flash Devices.
Any pitch device on 0.40mm pitch or higher.
Socket is easily mounted and removed to & from the PCB due to solderless pressure mount compression spring probes which, are accurately located by two molded plastic alignment pins and mounted with four Stainless Steel screws.
The Gold over Nickel-plated compression spring probes leave very small witness marks on the bottom surface of the device solder balls.
Standard molded socket format can accommodate any device package of 13mm or smaller, by using machined (for small quantities) or custom molded (for large quantities) pressure pads and interposers.
Pressure pad compression spring provides proper force against device and allows for height variations in device thickness.
4 Point crown insures “scrub” on solder balls, and raised tip probe provides “scrub” on pads.

See “PCB FOOTPRINT TOP VIEW” for requirements.
Requires four #2-56 screws and PEM nuts for mounting – Not supplied (mounting holes size shown may differ depending on PEM nut selected).
Sockets must be handled with care when mounting or removing sockets to/from PCB to avoid damaging spring contacts.
