The manufacturing of these 20 two-layer FR4 Panel PCBs centered on a custom stackup to achieve the specified 2 mm thickness. Measuring 222 x 154.5 mm with 1 oz copper weight, the boards featured standard 6/6 mil track and spacing along with a 0.4 mm minimum hole size. Material preparation and lamination processes were adjusted for the thicker material to maintain flatness and stability through circuit imaging and etching stages.
Green soldermask and white silkscreen layers were applied before the HASL Lead Free surface finish. Molten solder coating combined with hot air leveling created a consistent, reliable coating across the panels. Comprehensive electrical testing then confirmed circuit integrity and compliance with the design requirements for the full batch.
The complete production sequence, encompassing engineering review through final testing, concluded in 2.3 days. For this panel PCB order without impedance control, execution emphasized standard process parameters while addressing the demands of the 2 mm board thickness, ensuring uniform quality and dependable performance in the delivered panels.
