2 Layer FR4 PCB Production Record #FR4-20260812-002

This order involved the manufacture of five double-sided FR4 boards, each 93.3 x 117.7 mm in size, 1.6 mm thick, and finished with 1 oz copper layers. The specified 5/5 mil track and spacing called for precise control in the imaging and etching stages to achieve the required resolution without compromising trace quality. Standard material preparation and a standard PCB stackup supported an efficient workflow, given the lack of blind vias or impedance control demands.

Following solder mask application in green and white silkscreen printing, the boards received a lead-free HASL surface finish via molten solder coating and hot air leveling. This approach delivers a cost-effective, robust coating well-suited for standard assembly processes. Every board then completed electrical testing to confirm full functionality and adherence to design specifications.

The entire production, including all key manufacturing processes, wrapped up in 2.2 days. Outcomes reflected steady process control and consistent results across the small batch, meeting the customer's expectations for these standard yet detail-oriented 2-layer FR4 boards with HASL Lead Free finish.

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