| | I recently switched from solder paste in 500 gram jars to 500 gram tubes. I did this to try to limit the time the paste is exposed to the room environment. But we have a need to clean the stencil every 4 - 5 boards which means taking the bulk pas

We use tacky flux, we just make sure the left over solder on the board is really flat, it kinda replaces paste, although there's probably less solder left then there would be paste.

SMTNetters, I have a product coming down the pipeline that we'd like to make pure double sided reflow, it'll be RoHS product, and the hope is... we'll be able to solder the thru-hole stuff by screen printing solder paste and reflow soldering. Anybo

I have a problem with solder getting into exposed gold pads. What is the best rework procedure for removing the solder and restoring the gold condition of the pad? At the moment, we are also covering the gold pad with kapton tape prior to solder

Is there anyone who can tell me what is the maximum allowable soldering temperature when soldering a TQFP (Thin Quad Flat Pack) device in a reflow oven? We recently used a CY7C375i in a TQFP160 package and we experienced warping (bending) of this com

Hi, Has anyone here get some experience with SMT connector soldering? We were having really hard time to solder this AMP 50/50 Grid connector. Every connector installed has a few pins just sit on the solder. We use AIM 293DX2B NC solder paste, 60

Reflow and wave flow solders have to be changed more often because of contamination. Pb free PCB's don't solder as well so you will likely have to find a new process or supplier. The higher temperatures heat soak the components so they all need to be
