Thanks for the replys'. So are you saying that SMD adhesive contains a flux agent?, because at this point in the process the boards have no solder on them at all, it's all done at a solder bath after the chips have been bonded.

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

According to J-STD-004 "Requirements for Soldering Fluxes", fluxes are classified by their chemical composition, activity level and halide content. In this scheme, each flux type is identified by a 4-character designator, where: * First two character

Yes I have read that standard, but it doesn't tell me what I need to know. Both have the same activity level and halide rating (L0) The AIM technical guy told me RO is a natural gum rosin, while (RE) Resin has more processing or something (maybe so
