2 Layer FR4 PCB Production Record #FR4-20261017-002

This order consisted of 20 single 2-layer FR4 circuit boards with overall dimensions of 74.93 mm by 144.78 mm, a board thickness of 1.6 mm, and 1 oz copper on each layer. The minimum trace width and spacing of 5/5 mil represented a tighter geometry, necessitating careful process parameter selection during circuit imaging and etching to ensure clean lines and proper isolation. Specified with green solder mask, white silkscreen, 0.3 mm minimum hole size, and HASL Lead Free finish, the boards followed a default stackup without impedance control or blind vias.

We prepared materials according to the design and applied the solder mask before proceeding to molten solder coating and hot air leveling, which provided a uniform lead-free surface for soldering. Electrical testing was performed on every board to confirm there were no opens or shorts, supporting reliable delivery of the full quantity.

The production was completed in 2.3 days, with the executed processes delivering consistent quality that meets the demands of this particular specification set. The outcome reflects effective manufacturing execution for small runs featuring these parameters.

This order also received positive feedback from the customer regarding the consistent quality and reliable delivery. View the full customer review→
