Very interesting, how you can answer that with that many details that you gave us. Here are some preliminary questions, before anybody can give you any answer: Pb or Pb-free? 3mil stencil or 8mil stencil? How many shifts? Quantity will depend also o

Are you using a regular barcode scanner, or a smartphone app? When I print QR style codes on labels, I often use my phone to verify the print, but I've found that sometimes, especially when I print very small, or a very dense barcode, my phone won't

A fairly dense brickwall would have 0.020" (0.05mm) spacing

Currently I am running a very dense PCBA using a PCB less than 20 mils thick. We have two facilities running this product. One is using Nitrogen during reflow one is not. What is the advantage and disadvantages of using Nitrogen during the reflow

I've got a 100mm X 70 mm Dense PCB...The via holes used is 1.0 mm some are under SOIC's ...what problems that this type of via design poses ? all ideas are welcome ! thanks and regards, armin

Looking for recommendation, need your on hand experience to decide on narrowing stencil opening relatively to actual pad on pcb for 0603 and 0402 components also info on stencil thickness ? (I have a very dense board with 0603 and 0402 comp.) Thx

"On the average we touch up about 6 - 12% of all solder joints." Do you mean at least one joint on 6-12% of all your boards, maybe? Sorry, I can be dense....

Shy: Oh, we NOW understand what you're asking. Sorry to be so dense. We agree that the standoff of component from the board could end-up being a little heigher than the pad height when using chipbonder adhesive. We rarely see a problem.

Flux is less dense than metal so it 'floats' to the back NOT the tip when the tubes are stored tip down.

Thanks for the info mike. How well do these batch cleaners work with densely populated through hole boards that were solder with no clean flux? Is there a problem with water getting trapped under large capacitors? I'm using kester 959t for flux on b
