Manufacturing Summary
For this order we manufactured 75 units of 2-layer FR4 panel PCBs using a custom stackup, 1 oz copper, and 2.4 mm overall thickness. The elongated 94.21 × 275 mm format required precise material preparation and lamination control to maintain flatness and dimensional accuracy across the panels. With standard 6/6 mil trace spacing and 0.3 mm minimum holes, circuit imaging and etching followed conventional parameters, delivering clean geometries without requiring advanced geometry techniques.
Green soldermask and white silkscreen were applied prior to electroless nickel and immersion gold deposition, producing a uniform ENIG surface finish that supports reliable soldering and corrosion resistance. Electrical testing verified continuity and isolation on every panel. Completed in 4.6 days from engineering review through final inspection, the run demonstrated steady process control for these thicker, extended panel boards.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
