Interposer in Socket phone

Mobile phone test fixture,also called Socket Phone, is more populared with product designer and product manufacter. With mobile phone test fixture, enginners can do mobile phone functiont test,  failure analsys, compatibility test,etc. 

Interposer design is applied to Sireda's socket phone .Compared with traditional socket phone, Sireda's product with interposer have following advantages:

  • Aviod problems of pad co-planarity, oxidation after de-soldering.

  • Pogo Pin works in interposer, instead of PCB  board, aviod damage of PCB board.

  • Interposer with thinker gold plating, make test fixture more durable and stable.



Sireda Technology have developed test fixture for most popular CPU in market, like Qualcomm  MSM8953、Qualcomm MSM8998、MTK MT6797T,etc. More mobile phone test fixture, please click Socket Phone Catalog
