If an OEM and room is available on the PCB....have pin location aids silk screened on the boards. Groups of 10 are typical. might look like 1.........10.........20.........30 continue this around the device. Otherwise, ???

Consider: * Changing your temporary solder resist [TSR] to a light cure. * Contracting with your board fabricator to apply the TSR. * Gaining better thickness control of your application process by silk screening the current TSR. * Forcing more air c

Chris is right. You can do a good visual after placement if you have outline marks on your silk screen. That helps a lot. What size BGAs are you talking about. That would determine how critical you want to get with inspection.

Unfortunately our customers expect this coating on the boards so that is not an option. There must be something that can mark underneath without washing off. The silk screen doesn't wash off

Choose a supplier who has a strong team of technical professionals and has gained expertise in providing a silk screening process to reduce PCB artwork cost used in PCB Fabrication.

Hello, I know I will probably get a dozen "check the archives" answers, but what the heck. What is YOUR typical polarity mark for SMT devices? Do you use silk screen or cut a corner off a pad? How do you identify pin one on ICs? Let me know and

Is there silk screen on the pads? Other than that I would look for what has recently changed. Running smooth for a year and now all the sudden a problem. New microscopes always seem to do this trick as well. Amazing all the "defects" one can fi

Crappy piles? Weren't they a hard rock band in the 80's? I know on most of our boards the little silk screen dot is just the component identifier in really small font when looked at in Gerber. But this dot isn't very big, so I see how it can affec
