For selective soldered components, or even hand soldered, with vertical bend components, the body of the component, in this case a resistor, is making contact with the surface of the PCB, making it impossibe to visually see the solder fillet. Or to d

We do one of two things here; 1. We have cut up a bar of solder to different lengths, wieghts, etc. and place them on top of the offendinding floater, or 2. On selective wave pallets we will build a jig/clamp to hold down the part.

I would like an interpretation of a solder fillet on a 5 side termination cap. (Ref: IPC-610, sec. 8.2.2.6). My question pertains to the definition of dimension F, and what constitutes the top of the fillet. Does the top of the fillet end at where

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
