Manufacturing Summary
This order consisted of 10 panels of a 4-layer HDI PCB, each measuring 210 x 100 mm with 1.0 mm thickness and 1 oz copper weight. Featuring 4/4 mil trace and spacing, 0.1 mm minimum hole size, blind vias, and a custom stackup, the boards required precise process control during fabrication. OSP surface finish was selected, paired with green soldermask and white silkscreen lettering.
Manufacturing commenced with engineering review and material preparation, followed by inner layer imaging, circuit etching, and careful layer stack alignment prior to high pressure lamination. The blind vias demanded accurate drilling and plating sequences. Solder mask application, organic coating for the OSP finish, anti-oxidation treatment, and comprehensive electrical testing completed the workflow.
The production was executed over 7.8 days, yielding panels with consistent layer registration and reliable via integrity. This approach ensured the tight-geometry multilayer boards met all specified requirements for the customer.
