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.
For any pitch device on 0.40mm or higher
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.
Small overall socket size/profile allows maximum number of sockets per BIB, 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

See “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.
