We have a new SMT line, our customers are asking us the validation of the process. Not only the validation of the resulting assembled board (solder joint...) but also a validation of every single machine in the line (ex. stencil printer...). For exam

It isn't an FDA validation. I think Steve has centered the problem. I have already defined all the steps and all the procedures of the process, but now I must run X boards, Y times, through each piece of equipment (as he said before); the question is

Defining failure modes will help determine what you need to quantify in all processes. Personally I wouldn't pursue the DoE angle (varying setup parameters to determine robustness). 1)How about % pad coverage, paste thickness, and accuracy? Define w

you could do a capability analysis on the printer.....setup the printer with your print parameters and select a metric (say paste volume deposited) and find out Cp and Cpk values

As Russ say, you can buy kits from Practical components and make your tries, the send those pcb's to your solder paste vendor for analysis.I am using Senju Lead free solder and I send boards to them then they cut the board and analyze your solder con

Pressure printing systems Conventional stencil printing techniques have fundamental limitations as regards paste handling: The volume of paste available for printing is limited, so frequent replenishment is necessary Paste is difficult to c

todd the best answer is this" don't use the dispenser it will waste to much solder paste" Harry
