Fixture Design and Contact Technology:The wafer, with the WLBIcircuitry (sacrificial metallayer) applies, sits in a fixturewhich supplies properalignment, thermal stress andcreates the electrical testpath.Motorola Inc. / SPS Group! Die on the wafer areelectrically grouped intoclusters and share powerand drive signals incommon37
! Electrical contact is made with the waferthrough the use of pogo pins interfacing withtest pads provided through the WLBIcircuitry applied earlier! Pogo pins specially designed to providerobust electrical and mechanical contact -pins are replaceable in the eventperformance becomes degradedMotorola has used this system for severalyears to provide KGD for use as Flip Chip orwire-bonded die in the automotive industryand for providing non-volatile memory chips.38
