OUR HDI Capability
Definition: HDI PCBs utilize microvias, blind/buried vias, and build-up structures to achieve higher wiring density per unit area — ideal for space-constrained applications.
Key Applications: Smartphones, wearables, medical endoscopes, automotive ADAS modules, portable electronics.

Common HDI PCB Stack-ups
Understanding the various stack-up configurations in HDI PCBs allows designers greater flexibility in layer assignment, component placement, and routing. This enables more efficient use of space and better optimization of the board layout. The common HDI PCB stack-up structures are illustrated in the diagram below.

Featured Product Solutions
After years of dedicated R&D and continuous technological advancement, Hing has established itself as a benchmark in the rapid manufacturing of small to medium-volume HDI PCBs. Evolving from early 1+N+1 and 2+N+2 stack-ups to today’s advanced 3+N+3, 5+N+5, 6+N+6, and 7+N+7 configurations, we have successfully transitioned from fast prototyping to reliable high-volume production. This journey reflects our commitment to stringent quality assurance and has shaped Puruidy into a trusted name in precision PCB manufacturing.
