Brief Introduction to our PCBs


PCB Process - Introduction to HDI
HDI (High Density Interconnect): High-density interconnection technology, mainly using micro-blind / buried vias (blind / buried vias), a technology that makes multilayer PCB circuit board circuit distribution density higher. The advantage is that it can greatly increase the usable area of ​​the multilayer PCB circuit board, making the product as miniaturized as possible. However, due to the increase in line distribution density, it is impossible to use traditional drilling methods to drill through holes, and some of the via holes must be drilled with laser drilling to form blind holes, or cooperate with inner-layer buried vias to interconnect.Generally speaking, HDI circuit boards use the build-up method (Build Up), first do or press the inner layers, laser drilling and electroplating on the outer layer are completed, and then the outer layer is covered with an insulating layer (prepreg). ) and copper foil, and then repeat the outer layer circuit making, or continue to laser drill, and stack the layers outward one at a time.

Generally, the diameter of the laser drilling hole is designed to be 3 ~ 4 mil (about 0.076 ~ 0.1 mm), and the insulation thickness between each laser drilling layer is about 3 mil. Due to the use of laser drilling many times, the key to the quality of the HDI circuit board is the hole pattern after laser drilling and whether the hole can be evenly filled after the subsequent electroplating and filling.

The following are examples of HDI board types. The pink holes in the picture are blind holes, which are made by laser drilling, and the diameter is usually 3 to 4 mil; the yellow holes are buried holes, which are made by mechanical drilling, and the diameter is at least 6 mil (0.15 mm).
