You would have to tell us what machine brand you are using, as everyone has his own idea how to recognize X-outs. I find the auto-recognition very time consuming ( non-productive machine time ), unless the camera could recognize an image in one shot

1.0 X-OUT POLICY 1.1 Each Panel not to contain in excess of X% X'd-Out boards. 1.2 Each X-Out board to be marked in a manner so that Pick & Place equipment will not attempt to insert those boards X'd-Out such as fiducial reference hole for paneliz

Be careful when using a sticker, if it is too thick it can affect the print, you may get leakage which can cause the underside of the stencil to get dirty. Another option depending on the quantity is to segregate the boards so that you do not have t

In the case where fiducials with a HASL finish are removed from a panel in the depanelizing process, what do most people do for disposing of the rails? Since the HASL finish has lead in it, is it generally required that they be disposed of like print

We remove the fiducials by pushing sideways on them with a hot soldering iron. The copper pad separates from the FR4. We collect them and dispose of them. We have thought of disposing of the rail material with the boards, but our recycler doesn't w

Never heard of flux residues forming a lense. The first thing that comes mind when thinking about your 'fog test' is: Ionic Contamination While this seems pretty far afield from your interest in optical effects, I'll continue briefly. A reverse

The only reason MPM and DEK would decide to do such a thing is if they have determined that their low end market's future is not in this country but in China. It makes sense if most of those systems end up being sold into that market, why not simply

It is possible that sooner they will build their High End Equipment in China since most of the CM's are moving to China. But what will be the effect on the quality of these equipment and how will that impact their reliability will be a big question.

From my understanding these China OEM machines are for very specific production with low flexibility. i.e. Smaller board sizes.....machines just for memory modules. With those examples they will beable to reduce conveyor sizes, linear motor sizes whi

All DEK 248 semi-auto printers have been built in China for quite some time (years). Its shipped to the UK from China. All DEK ELA models are now built in China (past 6 mos.?). Thats the fact Jack. All MPM models are built in Mass. Its the savings in
