You can also look to remove the silkscreen layer. Components on an assembly of this size can be easily identified with a seperate Assembly Drawing. But I'd also look to incorporate polarity indicators into the copper layers. That way you wouldn't ne

If you want to put them in a single lane to feed you pick and place, there might be some software challeges like first printer skip first board and print second....(for this you will have to contact your printer manufacturer,they will probably do it

Hi Samuel, The issue your seeing is caused by lack of control of your board shops Immersion gold plating line. I would reject the order back to them. Their gold line baths need to be checked or they had a poor rinse after nickel plate before adding

I agree, you will likely need a carrier being that thin. without seeing the trace layout I’m not sure about relieving the carrier to accommodate them. if evenly distributed you shouldn’t to go that far. Are parts on both sides of the board? Don’t mak

A good fixture is the key here. The first side should be easier than te second(if double sided). In both cases I will try to level the top of the board with the top of the fixture. Try to lock with pins comming from the fixture to the PCB holes. This

Water soluble process, yes. The machine is old and fixed at 4 ft/min by someone way before me. Looking into ways to reverse that to allow for adjusting the conveyor. Trying to determine how the contamination gets onto the boards. So far testing has i

Jorge: I took this total posting to several fabs at IPC APEX. None was satisfied with the answers you receive from your supplier or the Forum members. They suggested that you get your board analyzed. They were surprised that your supplier didn't in

Good to hear, thanks for the response. Once you get the program fine tuned, do you generally have most boards that are inspected pass with the green good screen or do you generally have to review a few defects? OF course this all depends on passing r

Are you doing this to minimize solder paste splattering? Is this a value that you use for all QFN's (would the overall size of a QFN matter)? I was told reducing placement force with these components is recommended so just was wondering what is bein

If anyone still disagrees with you point, out that the "of each" refers to individual pads. If the 95% refered to 95% of the pads it would not have said "of each". Also someone correct me if I'm wrong but isn't this standard to do with solderabilit
