This production record covers a run of 10 panel PCBs fabricated on 2-layer FR4 with overall dimensions of 179 x 270 mm and a finished thickness of 1.6 mm. The boards utilized 1 oz copper weight, 6/6 mil minimum trace and spacing, and 0.2 mm minimum hole size. A custom stackup was followed to meet the specified mechanical requirements, while green soldermask and white silkscreen completed the visual specifications.
Given the immersion gold ENIG surface finish, particular attention was paid during electroless nickel deposition and subsequent gold plating to secure even coverage and strong intermetallic bonding. The processes of circuit imaging, etching, and solder mask application were carried out under standard conditions suitable for this conventional geometry, ensuring clean edges and accurate registration.
Following completion of the key manufacturing steps, each panel received thorough electrical testing. The order moved efficiently through the facility and wrapped up in 2.5 days, providing the customer with dependable FR4 PCBs ready for immediate use.
2 layer FR4 PCBs deliver cost-effective solutions for most electronic designs. Their simple structure enables consistent quality and efficient production cycles.
