AACTON AACTON ADVANTAGE AACTON has introduced a SUBSTRATE-CONTINUITY TESTING SERVICE for detecting opens ans shorts in prototype or production runs of multilayer hybrid substrates... OFFERS THESE ADVANTAGES 3 day turnaround Almost no restriction on the number of test points. Low NRC and Setup charges A known perfect substrate is not required. No special... for each substrate to aid in any possible rework. 3. Historical lot information, including a summary of common failure locations.

AACTON PROCESS PROGRAMMING TESTING PROCESS How does Aacton test multilayer substrates without a known perfect substrate or special fixturing? Each conductor line has a finite... capacitance with respect to a ground plane (workholder). In our case, this capacitance is determined by the area of the conductor line and the dielectric constant of the substrate... and printed Dielectric between the workholder and conductor line. By using a spring loaded pogo probe, Each conductor line is tested on five substrates (assuming random failures...
