Sometimes you gotta do what you gotta do! We have to perform this on occasion as well. We perform this when we cannot get a board to stay free of tacoing, oilcanning, sagging or warping. (we needed a bigger preheater dimension wise) We have one no

My guess from your description is that you're talking about the board at stop sensor (mounted on camera) that is seeing the board, but the board edge is not hitting the stopper. Either the board stop is not extending fully, or the board is sagging an

We use TraCon's TraBond 2112 for staking applications where larger gaps are involved. It is formulated for PCB staking applications. The material is very low sag and high viscosity. It's 2part and comes in handy bi-paks. Work life is 20-30min.

My personal preference is for manual set-up on the conformal tooling and have not seen an issue with bad support due to parts positioning variation... but if this becomes a legitimate issue, you can run in auto mode to reconform for each board (I lik

I am wondering if anyone has had issues with their Heller oven rails warping. It appears that our 1800EXL and 1900W oven rails sag after time. They eventually contact the safety mesh and then create hestitation of the chain, thus creating defects.

Hi there, I used Grid-Lok and some other PCB support from Quik-Tool (don't ask me model :) ), which is pretty similar to Grid-Lok, in Viscom machines. We also had jigs for high volume products similar to those you would use for PCB routing, but with

| I am looking for information on the amount of stress a component sees during the depaneling process. I am currently specifying a new piece of depaneling equipment and I have not found any studies that quantitatively compare the amount of stress di

| I'm also in the "Don't score it" camp. Routed breakaways are much better. If your wave solder process has decent control on the wave height, you shouldn't worry about flooding the boards. | The fine pitch consideration for panelizing - Since you

Am I missing something here? I usually put some type of stiffener or support on the leading edge to make sure the PWB doesn't sag in the middle from the preheat. If I had to add a bean bag with shotgun pellets or BB's I would have boards falling out

Hi Guy's.... Was thinkng about i more this moning..in the shower actually...sometimes think I do my best work there!. So far I'm looking at stuff like integrating the DFM study to show thing's that are going to present production / process issues e
