This production record covers 100 pieces of 2-layer FR4 circuit boards measuring 110 x 180 mm with a standard thickness of 1.6 mm and 1 oz copper layers. The specifications included conventional 6/6 mil minimum track and spacing, 0.3 mm holes, white solder mask, black silkscreen, and HASL Lead Free surface finish, without impedance control. These parameters allowed us to execute the order using established process parameters for double-sided PCBs.
Following a detailed engineering review to validate the custom stackup, material preparation commenced using quality FR4 substrate. Circuit imaging and etching accurately defined the copper patterns, after which we applied the solder mask and completed the surface treatment via molten solder coating and hot air leveling. Full electrical testing was conducted on all boards to ensure compliance.
The manufacturing was completed within 6.3 days, delivering consistent quality and reliable performance across the entire batch for this standard yet detailed FR4 PCB order.
This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
