1. Migrate to horse-shoe pad design. 2. Verify your furnace is level. 3. Verify your chains are not jerking around. 4. Speed control for fans / gas amplifiers are correct or normal? 5. (this happended to me once) Make sure you don't have any f

We had 2 at my last company. As I recall we had a hell of a time with bad blower motors. I'm not sure how you'd check on that, but maybe that problem has been fixed by now (it's been a few years). good luck, pr

Are You planning to produce a RoHS compliant product? If You just are going to reflow non RoHS compliant components with a "RoHS oven profile"; make sure that the comps. can withstand the higher solder temperature. As we see it; it is a big reliabil

for sure it's an excelent topic, in Mexico we've used almost any brand in the market (Research, Heller, Electrovert, Rhem, Vitronics, Conceptronics, BTU) and after all those names, we could see that Vitronics is a good opton, good service, not too mu

I just noticed that you mention 2-5mm off, that is huge! It would seem to me that there is an external force here to move a part that far. Things such as a heavy air stream that for some reason is really hitting this part, something on the PCB unde

Jay, What are your board sizes? What is the maximum size that you envision reflowing? 10-50 boards a week . . . is that in a single run or broken down into a few boards a day/hour? Do you have a high mix or is it a single product? Are the boards

We are experiencing a blistering problem during our process of lead free assembly. The customer has supplied us with the bare fab rated at 140 Tg. I am under the assumption that the Tg rating should at minimum be 170. Does anyone know if there is

Hello all, I am looking for a high temp lead free solder wire to use when attaching thermocouples for oven profiling. I figure something that reflows at 270-300c would do the trick. Can anyone give me a Brand, model# for such a solder? THANKS.

Well I honestly can't say that I have enough flow, so that's a good point. We don't have a flow meter or manometer on our reflow exhaust. How do you measure that? Or, is it just that you make sure your exhaust path is clean and the blower is wor
