The LS-alpha of Inter-Connector, used for testing IC-devices in packages like BGA, QFP, SOP, Flip-Chip or Bumped Wafers, consists of parallel rows of hollow gold tubes in a silicone rubber sheet.
The hollow tubes are positioned under an angle of 63° to ease compression and improve durability requiring contacts to use an offset of about half the thickness of the silicone rubber sheet. Randomly positioning the Inter-Connector between contact pads and providing compresssion wil realize a stable, low resistance connection.
The LS-alpha is a of the derivatives of the MT-type dedicated to specialized fields of device testing. The soft hollow tubes avoid mechanical stress on the contact lands or solder balls. The LS-alpha is providing ultra high signal transmission up to 110 Ghz.
