The profile that you should be using, hopefully, is detailed in the paste data sheet. Connect your thermocouples to various parts of the board, depending on layout, population etc; and then run some trials observing the profile on your oven monitor/

Your profile must be precise, your stencil aperture sizes and shapes are very important, and the size of the pads on the boards should be very close to what the part manufacturer recommends. We had some trouble with hi-temp paste, and discovered tha

They're IR, bottom side only. Frankly wave solder is not my forte (there are those that would claim nothing is), but I've personally been tasked with developing a process to do reliable, high volume bottom side SMT, so I'm drawing a lot from the tec

At the price of Durapol we'd never get the OK to have them made. The Al fixtures are cheap and a quick turn local item. As dense as the pth parts are I also don't think there'd be any room for any holes which I really think is the answer as far a

Gee Dave That's the first time I've ever seen myself listed for a quote! Brian, what your saying is on the whole right, on the surface of it the mask, as long as it's cured properlay shouldn't make a difference but I have to say that I've found so f

Sorry Dave should have said... At the mo all my data is for no clean processes using both matte and gloss finishes. That doesn't mean your feedback has to be limited to this area, I'm really trying to find out what the rest of the world are doing if
