This production record covers five units of 2-layer FR4 PCB with 8oz copper, measuring 210 x 180 mm and 2.0 mm thick. The heavy copper weight stands out as the primary technical challenge, necessitating thick copper electroplating and controlled etching to maintain the 6/6 mil line width and spacing. A custom stackup was followed to meet the specified parameters, including 0.3 mm minimum hole size.
Key processes included engineering review, material preparation, circuit imaging, solder mask application in green, and white silkscreen printing. For the HASL Lead Free surface finish, molten solder coating and hot air leveling were precisely executed. All boards passed electrical testing, verifying the integrity of the heavy copper PCB features.
Spanning 13.3 days, the manufacturing delivered reliable boards suited for applications requiring high current carrying capacity. Consistent copper thickness and finish quality were achieved throughout the batch, aligning with the customer's expectations for this low-volume, heavy copper order.
