Manufacturing Summary
We manufactured 250 pieces of these 10-layer HDI PCBs in panel format, each board measuring 80 × 80 mm with 1.6 mm thickness and 1 oz copper weight. The design included blind vias, a custom stackup, 4/4 mil minimum track and spacing, and 0.1 mm minimum hole size. These tighter geometries required precise inner layer imaging, circuit etching, and layer stack alignment to maintain registration across all ten layers during high pressure lamination.
Green soldermask and white silkscreen were applied prior to electroless nickel and immersion gold deposition, producing a uniform ENIG surface finish suited for reliable assembly. Each production stage—from material preparation through solder mask application and final electrical testing—was executed according to the specified parameters. Batch AOI inspection verified trace integrity and hole quality on every panel.
The 27.2-day schedule allowed thorough verification at each checkpoint for this moderate-volume run. All delivered panels met the custom stackup and blind via requirements, providing the customer with consistent multilayer boards ready for immediate use.
