Some times the PCB manufacture sends PCB panels with bad circuits, there are three ways to make these PCB without placing parts on the bad circuit, Well two in fact plus my method. (1) Placing a light mark on a dark background (or reverse) then the

We are having an internal debate here related to minimum Conductor Width. Can you have your QA manager review this and advise. IPC-6012C-2010 3.5.1 Conductor Width and Thickness When not specified on the master drawing the minimum conductor width s

Hello all! For my mechanical engineering study I want to etch a strain gauge in the Wheatstone bridge configuration in a copper layer of an PCB. The goal is to measure the strain occurring in an PCB even during the press process! We can measure with

1 - Too messy, parts already come in nice easy to use machine compatible packaging, tapes, reels, tubes and trays. All you are doing is adding an extra step and complication. A key production aim is to reduce the number of steps. 2 - BGA - a chip wi

I've always used multiple verification, and it's worked rather well. But, it depends on the people that are doing the verification, and their commitment to accuracy. It also requires a little bit of extra time. Given your system, are you still get

Manual placement aids are often very similar, I would suggest it is quite difficult to tell them all apart. Most of them include some kind of carousel for bins of loose parts and have the option of a few tape "feeders". If you are building small volu

Hello everybody Lately our machine has been working pretty well, but it can’t last too long. Now, during this week’s production cycle, it began to increase the component’s reject rate to alarming levels (obviously the operators reported me when the m

Hi, is there some sort of gas (certainly refrigerated, possibly pressurized?) in which printed boards can be stored to extend the allowed time between SMT paste printing and placement? Or other technique for achieving this? Background: we're a smal

Thanks to Bobpan we re connected our wipe system and all the air actuators work fine. I still have a problem with the cleaner fluid dispenser. It is not moving as it should to dispense the liquid when we do the command. I suspect the values in the c
