hi, gald to hear that yr process is working well.....we are in the process of buying a wave with SN100C solder.....any pitfalls/precautions that you took during the transition? did you do any DOE for setting up the profile values?? are you seeing a

We're using the 1B73LOC conformal coating from Humiseal. We've seen some bubbling of the coating. Their tech handbook suggested reducing our oven ramp speed. Does anyone have a good profile for this? They've always pointed me to Nordson, and Nord

I think where the fuzzy thinking starts is by calling the recipe's; profiles. Or maybe I"m being too fussy. Idealy you want every solder joint to have the same thermal "profile" (not recipe). That is the temperature over time is best if identical fo

Just received "Circuits Assembly", July 2001 issue. An article regarding solder balls and aperture design, beginning on page 40. This DOE had aperture, reflow profile and no clean pastes (3 types) as attributes. It is advocated that a U-shaped a

Hi, We have solder reflow use with water soluble flux and Tin/lead process. There is special glass component which needs to mask during reflow soldering and wash flux+solder mask post soldering. The existing solder mask does washes off. But leaves

Patrick, Have you seen Al Gore's documentary on Global Warming, "The Inconvenient Truth?" It was okay, but I didn't like how Gore got political in a few scenes by slamming the current administration's environmental policies (or lack thereof...c'mo

Russ: you could divide your 600 in let's say 10 or more categories,category #1 could be the thinnest thickness and smaller board size and smaller components;category #2 thinnest thickness smaller board size and mixed small and big components; and so

Let me be the first to suggest; Get a better oven. 5 zones minimum. If you can't, you will have to have some way of profiling the board. Does the oven have thermocouple ports? If not you will have to buy some kind of termperature datalogger. Mayb

I would again suggest that you REALLY need to profile that board. It does sound like you're not getting enough heat to that component, but if you just crank up your reflow zone how will you know you're not overheating something smaller unless you b
