These five standard 4-layer FR4 PCBs were produced as individual boards measuring 65 × 100 mm with 1.6 mm thickness and 1 oz copper weight. The design used conventional 6/6 mil trace and spacing together with 0.5 mm minimum hole size, green soldermask, and white silkscreen. HASL Lead Free surface finish was applied to deliver consistent solderability for standard assembly processes.
Manufacturing began with engineering review and material preparation, followed by inner layer imaging, circuit etching, layer stack alignment, and high pressure lamination. Solder mask application, molten solder coating, and hot air leveling were then completed under controlled parameters to maintain uniform coating thickness and pad definition across the batch.
Final electrical testing verified continuity and isolation on every board, with all five units passing on first inspection. The entire order moved through production in 2.3 days, confirming repeatable quality for this low-volume conventional multilayer specification.
Standard multilayer solution offering practical routing density and controlled impedance for industrial and consumer electronics.
