Our ICT Guy here at my company loves to use lots of via holes as test points - via holes which are 0.040" diameter, and spaced at 0.004" edge to edge spacing! He doesn't like to tent the via's either, so I always battle via-to-via shorts at the wave

He's a troll. Nobody could be that goofy without trying.

Cal, thanks for the feedback. I've tried different adjustments to wave parameters with varying success. You know how wave is - what works today won't necessarily work tomorrow. ..and yes, we run Nitrogen on our waves.

Surely this is a job for Wavemaster Larry? Have you tried flux buster pins in your ICT yet? They are quite good at cutting through the crap on a board.

"Surely this is a job for Wavemaster Larry?" I know this is supposed to be a serious forum, but that's some funny stuff! 8 mil stencils. Suuuuure.

Well, im not sure what plane you guys are on, but I can back up my what im talking about. Ya see I wnet to Soltec traingin back in 1995 for our new wave. I got a diploma proofing that I know what i'm talking about. no one else in my company has on

Samir, From experience, the only board test situation where tented via's have difficulty with contact is with a Flying Probe type tester. Otherwise, for traditional ICT, the force of the pogo pins, correct probe type, and fixture design should do th

You're a piece of work! Why don't you work for any of the major wave companies? So how does slowing the conveyor speed eliminate drying flux? And when you slow it down, what speeds it up to make you say "I lower the wave because I get shorts going

For those of you who use via holes as test points, and the via holes must be filled at the wave, is it necessary to have a "dome" on every single test point, or is it sufficient to have the via "filled" with solder? The ICT preson here insists that

No dome needed. You should check what type probe you have. You can look here and consult with them: http://www.qualmaxamerica.com/qualmax/leeno/semi.asp?string=ICT
