I dont know if this helps but we do a 10-board-cleaning after 10 prints or cycles we stop and with lint free towels with alcohol and a air gun we clean it, you should clean one side then the other. Hope it helps

I would try it dry first, we have never used solvents in our SPM, AP-20 or UP2000. Wipe every 4 to 10 boards. Normally dont have to wipe when using epxoy.

Hi MSK, Stencil thickness: 5mils with laser cut Smallest pitch: 20mils Underscreen cleaning frequency: 10 bds per cleaning Note: We have decreased the cleaning frequency from 10 boards to 3 bds to reduce solder bridging after printing Regards,

Than, shall try to find 10 boards with mixture of good and bad samples. Measure it with three different operators and three different times. It will able to tell, machine repeatability and how to troubleshoot it.

Hello Mike, Recently a customer questioned why my company does not perform SPC readings. My answer was simple, we collected data for about a year without any major problems that couldn't be determined by simply looking at the pcb. It has been ab

the information on "slide lines" in this forum sounds fine, but if you have to stuff 10 boards with 100 or more components a slide line is not very practical. We therefore have 1 worker do the whole board. I assume that others face the same task. Wh

We just placed a 56 pin QFN, 1 per board, on 10 boards and had zero defects. A good paste job, proper placement and a correct oven profile are the keys. If these are set up correctly, on larger runs your defects won't be zero but they should be le

We check the resistors to value check them. We are using resistors that are not marked in any way shape or form. We also hand build everything so it is very possible to have our operators place the wrong part in the wrong spot. From a time point of v

Thanks Rob, I bought it. Agreed its a good way to get my feet wet. By my math, it should do 1 10" board per minute. Too fast for even my dream production setup. So I may become a huge fan if it works. Not considering Nitrogen unless it doesnt wo
