Absence of solder is just black/super dark red which still falls under any percent I could put in there. So it passes. Maybe I'm a bit confused on how the machine checks solder in general anyway... 0%-60% is a pass by default. Thats anything dark - s

Craig, Since you didn't share any detail regarding the component side of the board or what other components reside on the bottom side, I'm prepared to take a stab in the dark. Have you considered doing a double sided reflow on this board? Also

I am looking at putting a laser or ink jet marking system for barcoding of pcb's in our smt production area. As and inline system it will need the capability to handle different size boards. We use dark green pcb's except for couple red and blues m

Your reply was NOT out-of line. You're correct and I'm wrong. I apologize. I'm sorry I referenced your name incorrectly and implied things about you that I didn't mean. I should have said KerryN, when speaking of the dark side.

Aw Dave - you guys are so fashionable, are the dark green and red combos seasonal? caramel brown like a Pale Ale? I once heard that the green was chosen because it gives the best color contrast for white silk screens. As for color reflecting or abs

Sounds like your problem is your camera setting for Head 1 (Gain & Offset), are you rejecting any other parts on that head? Go to (Set) (Propers) (Cameras) (Gain & Offset) you can then zoom in and out to check light contrast. Check the numeric col

SR. Here is a shot in the dark but have you try'd KNS? I know they have been working on some cool polymers...send them a note as they may have something that meets your needs. They may not have anything that can be removed but it is worth a try. pol

The GSM can process black fiducials. To do so the fid must be programmed dark on a light background. You will need to adjust the lighting to optimize the contrast in order to be successful. If this does not work I belive that UIC offers lighting k

This is a shot in the dark for you. On some of our low running boards (5 pieace). Instead of turning the wash on the operators will use a good ole steam cleaner. We used DI water in this process. The main reason we started using this in the first pla
