Manufacturing Summary
This order consisted of five panelized 10-layer FR4 boards, each 95 x 62.37 mm with 1.6 mm thickness and 1 oz copper weight. The design incorporated a custom stackup, 3/3 mil trace and spacing, 0.15 mm minimum hole size, and impedance control. Engineering review focused on stackup impedance modeling and trace compensation to meet the specified electrical parameters before proceeding to material preparation and inner layer processing.
Layer stack alignment and high pressure lamination formed the 10-layer structure, after which green soldermask, white silkscreen, and immersion gold ENIG surface finish were applied. The ENIG process included electroless nickel deposition and immersion gold steps to provide a flat, reliable contact surface suitable for the fine features.
TDR impedance testing validated the controlled impedance lines, while comprehensive electrical testing confirmed circuit integrity. The executed processes delivered panels that matched the tight tolerances of this impedance controlled PCB configuration, supporting dependable performance in the intended application.
