This production run delivered 100 units of 2-layer FR4 panel PCBs sized 94.21 × 275 mm with a 2.4 mm thickness and custom stackup. The 1 oz copper weight supported standard 6/6 mil trace spacing and 0.3 mm minimum holes across the elongated panel format. Material preparation and lamination steps were adjusted for the thicker substrate to maintain dimensional stability and flatness during subsequent processing.
Green solder mask and white silkscreen were applied after circuit imaging and etching. The surface finish sequence included electroless nickel deposition followed by immersion gold ENIG plating, producing uniform coverage suited to the panel dimensions and thickness. All boards then completed full electrical testing to verify net continuity and isolation.
The complete order was executed in 5.6 days, resulting in consistent solderability and edge definition across the batch. These thicker ENIG-finished panel PCBs reflect the process controls applied to meet the specified mechanical and finishing requirements without deviation.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
