Manufacturing Summary
For this order of five single 2-layer FR4 PCBs, production centered on achieving 5/5 mil traces and spaces within the 77 x 137 mm dimensions. The 1.6 mm thick boards with 1 oz copper layers and 0.3 mm minimum holes presented a balance of standard parameters and finer line requirements. Application of lead-free HASL surface finish, green solder mask, and white silkscreen completed the stackup.
The sequence began with engineering review and material preparation. Precise circuit imaging and etching established the fine geometries, after which solder mask was applied. Molten solder coating and hot air leveling produced an even HASL finish, followed by thorough electrical testing that confirmed no defects across all units.
Completed in 1.7 days, this production run delivered boards with uniform quality in both the tighter 5 mil features and the lead-free HASL coating. The process parameters were maintained throughout to ensure each of the five 2-layer FR4 PCBs met the design intent for reliable functionality.
