I have never used a VP oven, but I did get a pretty good demo of one and was pushing hard for my company to acquire one. The issue ended up being that there was not an East Coast distributor for the "juice" and that became cost prohibitive to get sh

I'm not sure that you could reliably automate it. So it's probably going to have to be a Hand Assembly operation. Maybe hand applying a drop of glue and hand placing the cap before reflow would secure them together so that someone with an iron could

Not sure if I agree with your justification but I might need to read it a few more times to figure it out. I agree that aquiring a dispensing machine is is a good purchase. Maybe you should let him in on the material savings. How many adhesive stenci

Damn near impossible. You need to see a real change in the difference between the 2 elements you are reading. So to give yourself any hope run 2 long traces one top one bottom up the length of the board. Then compare to 2 wriggly traces at one end (o
