Thank you Graham and Steve, I realized I was running a bit too hot and that is easy for me to change. The problem however was that I have 14 other profiles that I had created that still give me varied results. I am still facing issues with each di

We don't use flex pcbs but have the same issue here. Most of our pcbs are HASL finish. I have looked at silver and gold immersion and both look really good under my color camera on my AOI. However, gold is more pricey. There is no additional cost

Batch cleaner

If the batch cleaner is truly closed loop, then 100% of all of the process fluid (water) is captured, filtered (particulate, carbon, resin) and reused. This answer is based on a traditional closed-loop batch cleaning system with an integrated water

So I actually tried that method as well. Took the P&P info that was provided to us in Mils, put together an excel formula sheet which converted all X,Y to mm which the aoi uses. Then came to the horrible conclusion that there was something in the cad

Hi again Bob, I'll go by your item numbers: 1. OK, I'll not worry about it. 2. Somehow, it seems to me that it must be doing something or in Run Step Placements there wouldn't be different behavior for Alignment type 0 vs. other settings. I know I'

2) Start with the PLC. What do the indicator lights tell you. Is your entry sensor working? Your PLC has status lights that should go on/off with the input/output conveyors. Can you be more specific about "not operational?" This is a broad stat

Most of this you have probably covered, but these are what have caused heating issues for us in our 1707 EXL. First, you would probably notice, but check that all blowers are turning by looking at there cooling fans in the top and bottom, Our 170

Seho 1135C Wave Solder can't generate sufficient delta wave height

Electronics Forum | Thu Sep 26 23:14:25 EDT 2013 | zsoden
