This production involved 15 units of 2-layer FR4 PCBs with 4 oz copper weight, board dimensions of 177.8 x 234.95 mm, and standard 1.6 mm thickness. Due to the heavy copper, the process incorporated thick copper electroplating and controlled copper etching to achieve the 10/10 mil track and spacing. These steps received close attention to ensure uniform thickness and accurate feature definition on the sizable boards.
Green solder mask and white silkscreen were applied, followed by electroless nickel and immersion gold deposition to create the ENIG surface finish. All boards then underwent electrical testing as part of the standard verification. The complete manufacturing cycle required 6.2 days.
Without impedance control or blind vias, the execution centered on delivering consistent heavy copper PCB layers and reliable plating adhesion. The chosen parameters and processes produced boards aligned with the specified requirements for current handling and connectivity.
