Electronics Forum | Thu Mar 03 09:04:26 EST 2005 | russ

Been following this thread and have a question, Why do "touch-up" people follow different criteria than "Q.C." people. It sounds like the root of the problem is not addressed but bandaids are being put into place. We have no "Q.C." department and

Inspection and splicing

Electronics Forum | Thu Dec 21 13:11:25 EST 2006 | SWAG

We have fought with cut-tape way too much. It's always a bad idea. We've tried a couple methods/devices for manual splice with limited success. Before you look into this I would ask them if they could supply you cut tape qty's inslusive of fairly

You are correct about the Manncorp machine, it was an MDC machine. The Essemtec machine is old(ish) but still runs fine, and last I knew they were still supporting it. My recent problem with Essemtec was in regards to software. I found a bug and sim

Europlacer feeders and trolleys

Go for Gen 2 NT feeders, the Gen 1 Feeders tend to be problematic the older they get whereas the Gen 2 feeders are a much better prospect. I've used 8, 12, 16, 24 and 44mm. Some problems to look out for is pull back of coverlay and removal of waste
