4 Layer FR4 PCB Production Record #FR4-20260911-041

This record covers production of 100 units of standard 4-layer FR4 panel PCBs. Boards measure 46 x 46 mm with 1.6 mm thickness, 1 oz copper, 6/6 mil track spacing, and 0.2 mm min hole size. The order specified ENEPIG surface finish, matte black soldermask, and white silkscreen on a default stackup, presenting considerations for uniform plating and mask application.

Manufacturing involved engineering review, material preparation, imaging, etching, lamination, solder mask processing, and electrical testing. Over 10.4 days, focus remained on precise layer alignment during high pressure lamination and controlled parameters for the ENEPIG finish to ensure reliability across all panels.

Resulting boards showed strong consistency with no registration issues and full electrical compliance. The combination provides good solderability and long-term durability for this matte black standard 4-layer FR4 PCB, meeting the customer's expectations for quality and delivery.

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