One approach in this direction is the use of an optical diffraction technique. The unique properties of the diffraction phenomenon make this technique useful and the validity of this technique in the evaluation of surface finish is investigated in this paper....
The IPC specifications for printed board surface finishes set the standard for quality and reliability in printed board manufacture today. Adhering to these specifications increases yield and performance, but involves tight process control and accurate measurement of surface finish thickness. Central to ...
Checking the performance of surface finish gages: the measurement of surface finish has come a long way in the past 60 years. We have advanced from fingernail scratch pads to microprocessor- and PC-based systems with inductive probes. We even have the choice of optical sensors to evaluate ...
