Which inspections are required for PCB bare board before shipping? Many customers are concerned about this question. PCB bare board need undergo multiple inspections, and can only be shipped after a shipment inspection report is issued.
1. Basic Inspection
Laminate Information: Type, Finished Board Thickness, Outer Copper Foil, Inner Copper Foil, Warpage, Ink, Color, Position, Marking, Minimum Trace Width, Spacing, Ring Width, Solder Mask, Surface Finishing, Special Process, Test Items, Films, etc.
2. Electrical Performance Test Report
1)Test Category: Single-sided, general-purpose, special-purpose, number of test points.
2)Test Parameters: Current, voltage, on-resistance, insulation voltage, etc.
3. Metallographic Section Analysis Report
Copper thickness, nickel thickness, gold thickness, lead-tin thickness, copper thickness of circuit, roughness, etching factor, coating crack, resin shrinkage, coating void, delamination, etc.
4. Impedance Test
