Sequential lamination for HDI PCB

Sequential lamination adds layers in stages so internal interconnects can be formed before later copper and dielectric cover them.

Laser drilling for HDI microvias

Laser drilling creates small interconnect openings in selected dielectric layers. Material, copper treatment, depth control and subsequent cleaning all affect the result.

Desmear and metallization in HDI

A drilled microvia needs a prepared dielectric surface and a clean connection to its target copper before subsequent metallization and filling.

Solder mask around fine-pitch HDI pads

Solder-mask openings and remaining dams must fit the package land pattern and the factory’s registration capability. Mask color is not a substitute for a process specification.

Surface finish for fine-pitch HDI PCB

Choose surface finish for pad planarity, solderability, assembly process and storage requirements. A preferred finish still needs a compatible land and inspection plan.

Panelization and utilization for HDI PCB

Panelization affects material utilization, handling, tooling, test and assembly. The smallest individual board does not necessarily produce the lowest lot cost.
