WebThe result of an SIR test is a measure of the resistance of electrical flow across the traces on a PCB caused by conductive contamination, such as the ionics from fluxes. High resistance is good and means the board is clean. The best practice is to assess and control contamination through ion chromatography (IC) testing, the “gold standard.”. Web4 sep. 2024 · The IPC recommends that leads be placed parallel to each other, perpendicular to each other, or at 45-degree angles to each other. It is common for a single PCB to have leads running in different directions, but leads should never overlap. Overlapping leads would be a violation of component spacing guidelines and could …
