Manufacturing Summary
This order consisted of 100 panels of 8-layer impedance controlled PCBs built on FR4 with a custom stackup. Measuring 207.5 × 271 mm and 1.6 mm thick, the boards utilized 1 oz copper layers with standard 6/6 mil trace spacing and 0.2 mm minimum holes. Impedance control was a key requirement, prompting detailed stackup impedance engineering and trace width compensation during the inner layer stages to ensure precise signal integrity.
Following accurate layer stack alignment and high pressure lamination, green soldermask and white silkscreen were applied. The panels then underwent electroless nickel and immersion gold deposition to create a durable ENIG finish. This surface treatment supports excellent solder joint reliability for subsequent assembly processes on the large panel format.
TDR impedance testing and full electrical testing confirmed all parameters stayed within tolerance across the full run. Completed in 8.6 days, the manufacturing sequence produced consistent impedance controlled PCBs that met every specified requirement for reliable performance.
