Folks, Thanks for all the info and suggestions but let me add a bit more to the pot. Our products work in a harsh environment and are classed as safety critical. Customer returns are our biggest concern, we don't get very many and feeling here seem

Hi, I think the comment about the board height is because the MYDATA checks the board height each time it loads a tool so this is eliminated from being an issue because the machine knows the PCB height. I don't think it's so much what height the PCB

I agree with all the prior postings! But I have some additional thoughts about this. If there is a build up of moistures (% humidity) inside the pcb; before you reflow the pcba; then you will have the result out of the oven, just as you described. My

I�ve seen new table-top machines for $ 15,000 at exhibitions, but only one time and the same vendor didn�t show up the next time. Realistically, new machines capable of doing 0402 and 20 mil and a few kpph under $ 15,000 do not exist. Any used mach

Dave, Answers to your questions: * From your pictures, the white residue appears to be only on the solder mask. Is that correct? If not, what is the location [eg, solder, nonsolder/nonmask areas] of the residue that doesn't show well in the pictur

Javi, The reason you have an exemption for your product is because there are reliability concerns for lead free and it is impossible at this stage to guaranty backward compatibility. If a cell phone, TV or radio fails, no lives are at risk, you just

What kind of problems/defects/process indicators are you having? It is likely that you will have to bite the bullet and get a thermal profiling mole to prove that your selected profiles are subjecting parts to the correct tempertures per part specs.
