I would say the balls are aminly on passive parts in the middle.

Dave, I am interested in a amine hydrochloride activated flux. Can you give suggestions on readily available fluxes that you have used that have strong deoxidization properties. I am looking at something that could be used in a pinch when the stan

Hello, I am trying to estimate hole filling after PiH process using phoenix x aminer X-Ray Machine. The question is how to select correct inspection voltage? Inspecting at 60kV 40uA all PiH holes appear to be completely black, that means completely

Rosin. A hard, natural resin, consisting of abietic acid [and pimaric acids in Europe] and their isomers, some fatty acids, and terepene hydrocarbons. Rosin is extracted from pine tree stumps. It�s an organic material distilled from oleoresin in p

No, none of us can tell you what is the acceptable level of halide content or contamination in flux residue. The level of harmful residues on your product helps determine the reliability of your product. We know nothing of your product, its custome

Haaaaa!!!! Soldering to plastic!!!! An apt analogy!!! I like to compare it to soldering to dirt. Some thing. In fact, you are soldering on nickel, when soldering on many things. It�s just that the gold, er Pd, flash enables the wetting mechanism

First, don�t get distracted by �OA� and �NC� formulations. This is nomenclature. We want to discuss the issue of �activity�. J-STD-004 "Requirements for Soldering Fluxes" classifies fluxes by their chemical composition, activity level and halide c

Dear All, In order to understand the soldering technologies in SMT, I'd like to understand why some cards are soldered and then cleaned, or only soldered whitout water cleaning nor "ultra sound" wavelength. I mean that I wonder why we use

Dave Frankly, I think you may be barking up the wrong tree. Like DaveF, I suggest that the process would be horrendously expensive with masking and so on. The $64,000 question is whether what you propose will serve any useful purpose. I venture to
