CSP/µBGA Test & Burn-In Socket for Devices up to 13mm Square

For Test & Burn-In of CSP, µBGA, DSP, LGA, SRAM, DRAM and Flash Devices. Consult factory for QFP applications
Any pitch device on 0.30mm pitch or higher
Socket is easily mounted and removed to & from the BIB 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 Au over Ni plated compression spring probes leave very small witness marks on the bottom surface of the device solder balls
Small overall socket size/profile allows max. number of sockets per BIB and BIB’s per oven, while being operator friendly
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 oxides
Signal path during test only 0.077 [1.96]

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 to/from BIB to avoid damaging sensitive spring contacts
