IPC-A-53 Revision C, Surface Insulation Resistance Test Board

The A-53-Gerber is a single-sided test board having six SIR test patterns which were designed for surface insulation testing. The test patterns consist of two comb patterns with 500µm (0.0197”) lines/spaces, two comb patterns with 318µm (0.0125”) lines/spaces and two comb patterns with 200µm (0.0079) lines/spaces. The contact fingers of the board are normally gold plated for compatibility with edge card connectors with the remaining metallization of bare copper when used for qualification but can be other surface finishes.
