Rick, Do you check both side of the board after wave? Can you check the orientation of components, missing of components and also the solder joint defects? We are also very interested in this type of machine. Thanks for the information. Carol

I am looking for a vendor that offers a board/stencil combo to evaluate screen print accuracy. Any suggestions?

There's a board called "SMTA Saber Board" that I have used. It has several different components types and is good in evaluating lots of different process equipment. This can be purchased from any of the "dummy" component companies.....

Re: no tru-hole on wave

If you have another container of flux that is a different batch try that. Dont forget to clear lines of old flux. check spray pattern width. The activators needed may be dead in flux.Since it is sudden my question would be what just changed?

Being its sudden and only 1 product I would suspect the PCB particularly the barrels in the plated through holes being contaminated.
