Walt; How can I say this politely...Garth used to work for me. His enthusiastic support of the APS machines was not based on reality. We have had so many problems with our 2 machines that we are getting rid of them. I hope you make out better. G

Most of the design considerations will be for the wave soldering of the SMT parts. Have you considered selective soldering pallets or masking as an alternative? One problem I have seen with the epoxy process is parts that are high off the board and t

Are the markings on resistors the actual value? Do AOI machines look for these markings or do they just look to see if a component is present and placed well? Can anyone attest to the solderability of upside down resistors? Can anyone argue that u

We currently use Epibond 7275 with MPM printers. Unfortunately we've had problems with Vantico (formerly Ciba) providing a consistent product. Last summer we had extreme difficulty printing due to excessively high adhesive viscosity (20% higher tha
