Here are the highlights from Session Four – “High Performance Probing” of the 21st annual IEEE Semiconductor Wafer Test Workshop (SWTW) from Monday June 13, 2011.
Bob Davis, Rudolph Technologies, “Testing Probe Cards That Contain Complex Circuitry“:
Over time, probe cards have increased in complexity from simple wire cantilever probes to those including passive components and digital control circuits. Some of these digital control circuits may even contain state based logic. At the same time the physical complexity of probe cards have increased in probe and channel counts, probe density, and total probe force. As a result, Read the rest of this entry »
