You're correct. It is curious. Possible angles to look at are: 1 WS609 loves moisture in the air. In high humidity shops, this paste hakes-on liquid. If this is the case, you should also see slumping, resulting in fine pitch bridging, and solder

guys, I am having a problem. During my rework (SRT) process, I am trying to reach a board temp of 150degC b4 the top heater comes down for the actual rework process. Due to which the flux (tacflux 20)is burning off and i am seeing lot of non wetting

I am currently building boards which have to be conformal coated (done by an outside source) in a no clean process. The conformal coating however, must be applied to a clean surface. The flux residue left from the paste has come into question. I h

Regarding nano coatings : Nano coatings are susceptible to wear during the printing process and cleaning processes. As they wear they flake off and can potentially contaminate your solder. There is not a lot of independent data available on this so k

We have been experiencing intermittent problems with the solder masking bubbling up from the bottom side of the board, after wave soldering. Our board fabricator claims that none of his other customers are experiencing this problem, and that it is pr

| I need some advice concerning reflow of a BGA-292. Since I am not ready to change my entire process to no-clean, I decided to place the lone BGA-292 on a proto run using our BGA re-work station. The pcb is a moderately dense, single-sided, 8-laye

| We use no clean paste and sometimes experience | flux splattering which gives spot on gold fingers. | Need help in analize the cause. thx. Dominic, That is STILL a problem huh? It's a tough one to solve sometimes...especially when you have as
