1498021773838812.gif Package can be BGA, QFN, LGA, QFP, SOP, etc

1498021773838812.gif Pitch can be as small as 0.35mm




  • CS test socket is designed for test, valiation or burn in test of IC devices like eMMC, eMCP, UFS, DDR, LPDDR, Nand, etc.

  • Can be applied as well for chip-off IC devices failure analysis, write-and-read in forensic application.

  • Patented structural rolling design with socket clamp makes it easy opeartion, less abrasion, so as to better socket life span.

  • Customized design and service according to customer's volume requirements, two options can be chosen, machined socket (for small volume) and molded socket (for big volume of more than 500 pcs). 

  • Customzied PCB board can be sold together with socket under customer's request.
