I have recently been handed over the waving operation here, and am unclear on how to address our recent issue with our Wave. We are using AIM WS-715M Flux in a Foam fluxer, and are using AIM SN-100C in the wave. The problem is on several of the assem

We have used thousands of them with no problems. They will not aid in "connector retention" unless you have a shear force at exactly the right angle. This is an advertising joke. They will help with alignment of the connector. Open your holes up so t

Dave, I would not recommend use of a multi-meter to determine high quality DI water resistivity readings. There are a number of reasons including a multi-meter�s lack of temperature compensation. We use a Myron-L resistivity meter to accurately de

Many thanks for your reply. We would like to clarify two things; 1. We have recently purchased a vision system with oblique viewing facility to rotate the camera with 40x magnification, which we find useful to inspect fine pitch components . 2. Wh

Hi Mika, We came across some difficulties with this type of device a couple of years back . After the proto run we needed to touch up the outside fillets to get stability and product to pass test. ( even though the manf. stated that there is no fill

Hi, I think the only solution would be to contact Fuji and ask if there is an interface to the machine to write software for it. I read somewhere that FujiTrax allows a IT system type connection which software could be written for. Another solution
