This production record covers a batch of 20 single 2-layer FR4 PCBs, sized at 50 x 145 mm with 1.6 mm thickness and 1 oz copper foil. The design utilized standard 6/6 mil track and spacing along with 0.3 mm minimum holes, eliminating the need for advanced geometry controls. An immersion gold ENIG surface finish was selected to enhance solderability, complemented by green soldermask and white silkscreen.
Execution involved engineering review of the files, followed by material cutting, circuit imaging and etching to form the traces. Solder mask application preceded the electroless nickel and immersion gold deposition steps, which were carefully monitored for proper plating thickness on pads and vias. All boards then passed 100% electrical testing to confirm circuit integrity.
The order was fulfilled in 3.3 days, resulting in uniform boards ready for immediate assembly. This run reflects reliable processing for modest quantities with ENIG finish on conventional 2-layer FR4 constructions.
2 layer FR4 PCBs deliver cost-effective solutions for most electronic designs. Their simple structure enables consistent quality and efficient production cycles.
