We know that solder pastes can be stored for up to 2 weeks at room temperature. If we return them to the refrigerator after 1 week of storage at room temperature, does the time reset, or can we keep them for the remaining week at room temperature? A

| hello, | | has anyone tried dispensing solder paste in thru holes instead of waving or hand soldering. if so how did it work out for you. | thanks for the input | | wayne | | | Once you start, depending on applications, you'll toss your wave s

Considerations are: * If the nonwetting is component lot specific, the could be solderability issues with that lot. * If the nonwetting is is a broader based component issue, the solderability protection on the component may require a different reflo

We r using QFPs of 0.5mm pitch and r not getting any soldering prob at the end.But some new customer insists upon the thickness check of the solder paste after printing. At present we don't hv thickness checking system.We r controlling the amount of

I find it hard to believe that AIM never contacted you either by the rep or directly. I switched to AIM solder 4 years ago after using several of their competitor�s pastes for the very fact that the products were as good but Aim�s technical support w

You have to figure this out for yourself for your paste. When I evaluate solder pastes I require good tack, no solder balls, and proper wetting after 4 hours at "reasonable" ambient conditions. I also print boards and put them in a temp/humidity ch

Solder paste thickness control is more important in SMT process. What controls do you have? I guess if everyone follows the critical control path, then there are always reduced problems. The issue is no one is perfect. Paste tends to be on the stenci

My question is refering to "stencil life". How accurate is this and is this something I can go by. The solder paste I am using is Kester R562, R562 specifications state that it has a 12 hour stencil life, optimal temp ranges 70-77 F, 35-65% RH. Ou
