2 Layer FR4 PCB Production Record #FR4-20260919-046

This production record covers thirty 2-layer FR4 boards measuring 76 x 374 mm with 2 mm thickness and 2oz copper weight. The long, narrow profile combined with heavier copper presented specific considerations for maintaining dimensional stability during lamination and etching. Standard 6/6 mil track and spacing along with 0.3 mm minimum hole size allowed conventional processing methods while still requiring attention to the increased material density.

We performed thick copper electroplating and controlled etching to accurately define the circuit patterns on these HASL Lead Free boards. Matte black solder mask was applied uniformly, followed by white silkscreen printing for component identification. The surface was finished with lead-free HASL through molten solder coating and hot air leveling, ensuring good solderability on the 2oz copper without lead content.

Electrical testing confirmed full functionality across the batch. Completed in 1.5 days, the run delivered consistent boards suited for power-oriented applications where the 2oz copper provides enhanced current capacity and thermal performance.

This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
