HDI PCB Manufacturing
Explore the operations behind HDI fabrication, from sequential lamination and laser drilling to copper filling, registration and electrical acceptance. Start with the manufacturing overview, then follow the operation that creates the greatest risk in your design.
Plan a build that can be reviewed, fabricated and verified.
A drawing becomes a manufacturing agreement when the layer constructions, interconnect spans, finished dimensions, material substitutions and acceptance evidence are explicit. The guides below help prepare that agreement without inventing a universal process capability.
