What is the HDI PCB
HDI is the acronym of High-Density interconnector, which is a technique for producing PCB, HDI in PCB
mainly includes Micro-blind hole technology. HDI PCB prototype has the features as follows:
1. Saving the cost of multi-layer PCB: when the PCB density increases to eight layers, the cost of HDI
PCB stack up will be lower than the cost of traditional stack-up process.
2. Increasing the line density to make the product more high precision.
3. Good heat dissipation and higher weldability.
Meanwhile, HDI is needed in all around the world. Different layouts have a great impact on the
price of HDI PCB, generally, we need to do a good plan before HDI PCB design so that enhancing good
performance and lower the HDI PCB cost.
