Hi Dave, You make a very good point. I think that the concern over lead is not so much in user's contact with the lead during the product's active life, but after its disposal. There is some valid concern over lead leaching out of circuit boards

Continuing the line of Michael's, the previous poster, comments ... The more Krispy Kremes, the better. Yeth!!! The more beer, the better. Yeth!!! The more epoxy, the better. Uh, I don think so!!! We look at this from a papa bear, mama bear, bab

Thanks for the input Mike (and others). As you guessed, via-in-pad is not my idea, and I'm resisting it as much as I can. One of our designers used this practice at some other company, says there were no problems, and wants to use it (via-in-pad) a

| | I am getting ready to purchase a spray fluxing system for a no-clean process. I have narrowed it down to the Nordson or Dover system. Does anyone have any experience with either. If so can you relate with me. I am a little leary of the Nordso

For Dean and the rest of you interested, I have reconciled many of my thermal issues with this machine and its peculiarities. The bottom side heater seems adequate, at 750 watts (not going to spend 10 grand extra for 500 more watts no matter what) a

| Also the preheating of the board is done to help evaporate any water/alcohol that is in the flux - water is a big problem in No-clean processes. From our experience, a temp range around 200f - no more than 220f is ideal for the bigger boards, but t
