How to Solder a Wire to a Pad
It seems like a fairly simple thing to do. What could be difficult about soldering a wire to a pad? Well, I hear three common complaints a...
Preparing Surfaces for a NanoBond®
The first time I was taught how to solder (as a child), I was told: “All the surfaces need to be mechanically cleaned and chemically cleaned.&rd...
Ball-Attach Flux WS-446-NRD for Poor Quality OSP-wetting
While on a recent trip to Malaysia, I interviewed two colleagues regarding trends in semiconductor assembly. My previously-published interview with Sz...
Cleaning No-Clean Solder Paste Residues in SMT Assembly
Folks, There is a lot of interest in cleaning PCBs that have been assembled with no-clean solder pastes. Recently I discussed the topic with my ...
SIR and ECM Testing For Water-Wash Solder Paste Fluxes
It is not often that we get a request for SIR (Surface Insulation Resistance) and/or ECM (Electro-Chemical Migration) results for a water washable/sol...
Flux Pens for Hand Soldering Solar Cells
A few months back, while discussing tricks for hand soldering c-Si solar cells, I mentioned flux . One tip I didn’t mention is how to APPLY......
Another Nitinol Soldering Flux Option
Indalloy Flux #2 is not the only option for soldering to Nitinol. There is also Indalloy Flux #3. Both fluxes are strong enough to clean the......
