The PerfectTest System is especially designed for monitoring the inner-layer registration error for high-density multilayer PCB products.It provides data for process control regarding variables that affect inner-layer registration. These variables include:

• growth / shrinkage of core material during fabrication
• artwork stability
• image transfer
• skew during lamination
• drilling errors

This system has been proven as a competent tool for identifying types and causes of registration errors, even if the errors come in combinations. After identifying the causes and symptoms with the data in hand, we can come up with the appropriate adjustment or improvement measures. This is proven crucial for ensuring our high and predetermined level of registration.
