| We are in the process of getting into no-clean paste and fluxes. One important issue in this is sodler balling. I have heard some people say that having a matte finish would help in having lesser solder balls and that the solder balls would not b

I faced problem over connecter's pin that were hot air soldered. This connector has 168 pins ( similar to the straddle connector ). The process is to apply the flux onto the connector's J-leads, and the hot air pencil were then ran thru' the leads to

Recommended procedure for soldering stainless steel [Atlas Steels Australia]: * Surfaces must be clean and free of oxidation. * A rough surface improves adherence of the solder, so roughening with grinding wheel, file or coarse abrasive paper is reco

Here are some answers to my questions after a good research. I also added more definitions that could help understand this esoteric language used in assembly, specially surrounding fluxes and their use. In blue italics are comments and extracts from

The Solderballs are on the botton side of the board.The solderballs are concentrated around through hole edge connectors, which have a Tin/lead finish and have lead pitch of 2.5mm, on top of this, random solderballs are occuring around test points. T
