Manufacturing of this batch of 50 six-layer HDI panel PCBs focused on the specific demands of a 216 by 280 mm panel size and 4/4 mil minimum track and spacing. At 1.6 mm thickness with 1 oz copper, the tighter geometries called for detailed engineering review and optimized exposure parameters during inner layer imaging to avoid any deviations in the etched circuits.
The process continued with careful material preparation, followed by layer stack alignment and high pressure lamination to bond the six layers securely. Matte black solder mask was applied uniformly, complemented by white silkscreen for contrast. An immersion gold ENIG surface finish was then selectively deposited to provide oxidation resistance and reliable soldering points.
Final electrical testing of all panels verified electrical integrity. This execution for the panelized configuration produced stable outcomes matching the customer's stackup and feature requirements within the scheduled 10.2-day production window.
