You did not tell us where your boards fit on the thermal mass range. That is key. I've run Pb Free low to medium thermal mass boards with good results on a 5 zone oven (5 top/5 bottom). You should not have a problem running a medium thermal mass boa

Hi, Ok, thanks for the info, and I had not considered that factor. Is this an issue related to the reflow temperature change in the oven, or a temperature change in normal product use issue? I will check out the standard, and do you know where it's

Our profile tempatures in the owen is: Preheat 6 zoones 135,155,165,175,185,195. Peak 3 zoones 255,245,240. We do check our profiles with test probs and a "Surveier" temrature recorder every 3 month and we are within the paste supplyer recommendation
