Products description:

HDI PCB: HDI (High Density Interconnector) PCB has smaller holes (≤0.15mm) in BGA or copper pad which will using laser drilling, and most of HDI PCB has intersect blind and buried vias. HDI technology becomes more and more popular for the field of mobile phone, PC, automotive electronics and other digital products.
