2 Layer FR4 PCB Production Record #FR4-20260814-011

Production for this batch of 20 two-layer FR4 PCBs proceeded smoothly according to the provided specifications. Measuring 42.25 x 60 mm with 1.6 mm thickness and 1 oz copper, the boards utilized a conventional 6/6 mil minimum track and spacing. The 0.8 mm minimum hole size supported straightforward drilling and plating operations. Matte black soldermask combined with white silkscreen was selected, requiring precise application to maintain sharp edge definition and strong contrast on the FR4 substrate.

Leaded HASL surface finish was executed through molten solder coating and hot air leveling, producing a uniform protective layer suited to both through-hole and SMT assembly. The manufacturing sequence of engineering review, material preparation, circuit imaging, etching, solder mask application, and electrical testing was completed in 2.5 days. Every board in the set of single PCBs passed continuity and isolation checks without rework.

This small-volume run with standard geometry and leaded HASL delivered consistent quality and reliable solderability tailored to the customer's exact requirements.

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