Challenges of Expanding Large Area Active Array for Fine Pitch Vertical Probe Cards
Semiconductor manufacturers are on a relentless drive to reduce the total cost of test at sort. A major contributor to reducing cost of test is increasing simulations Device Under Test which requires a subsequent increase in the probe card active area. FormFactor has developed a new probe card architecture to address the challenges of fine pitch, high CCC, and high temperature range for wire bond probing applications.
