High-Frequency Center Probe Test Socket for Devices up to 6.5mm Square

For test & dynamic burn-in of CSP, MicroBGA, DSP, LGA, SRAM, DRAM and Flash Devices
Any pitch device on 0.30mm 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 two 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 6.5mm 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 two (2) #0-80 screws (supplied) 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.
