This production run consisted of 15 FR4 panels in a 2-layer configuration, each measuring 210 x 148 mm with standard 1.6 mm thickness and 1 oz copper weight. A custom stackup was prepared to suit the panelized layout while supporting conventional 6/6 mil trace spacing and 0.3 mm minimum hole size. These parameters permitted standard circuit imaging and etching sequences to establish accurate copper patterns without requiring advanced geometry controls.
Green solder mask and white silkscreen were applied prior to surface finishing. Immersion gold ENIG was then deposited through electroless nickel and gold steps to provide a flat, oxidation-resistant finish across all panel surfaces. The complete process flow, from engineering review through material preparation, mask application, plating, and electrical testing, was executed in 4.5 days.
All 15 panels met specification limits with uniform results, delivering consistent solderability and electrical integrity suitable for immediate assembly. This order reflects steady execution of panel PCBs featuring immersion gold ENIG under standard FR4 parameters.
2 layer FR4 PCBs deliver cost-effective solutions for most electronic designs. Their simple structure enables consistent quality and efficient production cycles.
