Thank you for the answers to my questions. We are running two-lead LED insertions. Most of our PCBs are square between 9" and 14.25" in a 16 x 16 array, so pitch ranges from 0.52" to 0.90". Further complications are that most of the boards have th

I could help you with the SET features if I saw them. It's been about 4 years so I don't remember them off the top of my head. What you would do (nutshell) is get your non-rotated insertions dead center, then step through to a rotated insertion until

I haven't experienced this problem, exactly, but I have had issues with noise in digital circuits that appear to have gone away with touch up. The problem was that the customer blamed the noise issue on the solder quality, and he pointed to the fact

How do other people check their solder joint strength after a process change? For example, say you are getting wetting problems and you feel that a change to the reflow profile may help, or perhaps a slight change to the stencil aperture to reduce so

What's sad is, it really happened. I won't bore you with the details again. ;) Lloyd, I would love to have a nice Hi Scope too (I think Cchunks works for one of those big champagne and caviar corporate entities ;)) but if you can't swing it, at leas

We have a job that has through hole components on the top, and one 44 pin j leaded PLCC on the bottom. Presently we put the through hole parts in, run it throught the wave, dispense paste on the PLCC pads, and then apply hot air. Someone suggested we

Hello James. I've got a YesTech YTV-2050 system at work with one top-down camera, and 1 side-view camera for each of the four sides. I do have the side view cameras being used for automated side inspection. There are some parts with markings that are

My company recently aquired an asymtek coating machine and I have been using Humiseal 1B31, an acrylic coating, in it to coat all the boards given to me. They have now come to me and asked if it is possible to run Humiseal 1A33, a urethane coating, t
