2 Layer FR4 PCB Production Record #FR4-20261017-004

This production record covers an order for 20 pieces of 2-layer FR4 PCBs. The boards measure 105.54 x 62.86 mm and are built to a standard 1.6 mm thickness using 1 oz copper foil. With minimum trace and spacing at 6/6 mil and hole sizes starting from 0.3 mm, the design aligns with conventional manufacturing parameters. Green soldermask and white silkscreen were applied to provide good contrast and identification, while the HASL Lead Free surface finish ensured good solderability without the complications of more advanced finishes.

Manufacturing followed a logical sequence beginning with engineering review and material preparation. Circuit imaging and etching created the required copper features on both sides of the laminate. Solder mask application was followed by molten solder coating and hot air leveling to form the final surface. These steps were carefully controlled to maintain flatness and coating thickness across the panel.

Electrical testing verified the integrity of all 20 boards, confirming no opens or shorts. The complete order was fulfilled in two days, delivering reliable standard FR4 PCBs that meet the customer's specifications for general electronic applications.

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