HDI Printed Circuit Boards
HDI Printed Circuit Boards, one of the fastest growing technologies in PCBs, are now available at JHY PCB. HDI Boards contain blind and/or buried vias and often contain microvias of .006 or less in diameter. They have a higher circuitry density than traditional circuit boards.
There are 6 different types of HDI Printed Circuit Boards, through vias from surface to surface, with buried vias and through vias, two or more HDI layer with through vias, passive substrate with no electrical connection, coreless construction using layer pairs and alternate constructions of coreless constructions using layer pairs.
The most common 6 types of HDI Printed Circuit Boards include:
- Through vias from surface-to-surface
- Combination through vias and buried vias
- Multiple HDI layers containing through vias
- A passive mounting substrate without any electrical connections
- Coreless construction through the use of layer pairs
- Alternate coreless constructions through the use of layer pairs

Advanced Capabilities: Microvias PCB A microvia maintains a laser drilled diameter of typically 0.006" (150µm), 0.005" (125µm), or 0.004" (100µm), which are optically aligned and require a pad diameter typically 0.012" (300µm), 0.010" (250µm), or 0.008" (200µm), allowing additional routing density. Microvias can be via-in-pad, offset, staggered or stacked, non-conductive filled and copper plated over the top or solid copper filled or plated. Microvias add value when routing out of fine pitch BGAs (BGA PCB) such as 0.8 mm pitch devices and below. Additionally, microvias add value when routing out of a 0.5 mm pitch device where staggered microvias can be used, however, routing micro-BGAs such as 0.4 mm, 0.3 mm, or 0.25 mm pitch device, requires the use of Stacked MicroVias using an inverted pyramid routing technique. JHY PCB maintains years of experience with HDI products and was a pioneer of second generation microvias or Stacked MicroVias. Stacked MicroVias Technology offers solid copper stacked microvias providing rout-out solutions for micro BGAs.

Benefits of using HDI Printed Circuit Boards As consumer demands change, so must technology. By using HDI technology, designers now have the option to place more components on both sides of the raw PCB. Multiple via processes, including via in pad and blind via technology, allow designers more PCB real estate to place components that are smaller even closer together. Decreased component size and pitch allow for more I/O in smaller geometries. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
