"When we solving a problem we have to be absolutely sure it's really solved." Conversely, it's always good to return things back to the way they were when you conclude that THAT knob turn didn't solve the problem.

To me it speaks about teh quality of the engineers. I[ve seen both types, though Vlad

Sorry all I know is that storing the paste Tip down the flux will run to the tip of the cartridge so will be runny initially then dry up as you use the cartridge. Unless the Rheopump mixes it before application

Yes sorry you are right so you have answered your own question anyway. Dry to start runny at the end

I'm curious how many knobs have left to be turn? :-) Isn't time an issue in a production environment? Vlad

Here we go with another "solderability problem". How do you know the pads on the bare PCB are oxidized? Just based on its colour? If that is the root cause, then why ohter parts on the same board are fine? If you want to solve the problem, get it's

We are having a little trouble with what appears to be a crystalization between our fine pitch parts. The problem appears after a a thourough wash of the pcb when dry. It looks like lead wiskers/haze between the joints.We are using water soluable lea

hai, we r using type 4 solder paste in our pcb assembly process - we are now facing the following problem. 1. two component pads soldering was seemed uncoalesced soldered joint except all the other components. 2. what will be the problem & solution f
