Concept of HDI PCB Manufacturing


Key Words: HDI PCB Manufacturing

What is importance of  PCB ?

Printed circuit board is commonly known as PCB. Its role is very vital in the electrical and electronic industry.  Conceptually, PCB is a board made up of a very thin flat metal or hard plastic type board and upon which so many electronic components are mounted. The prime function of the PCB is to provide mechanical support to the device. It has a major role in assisting electromagnetic shielding, heat transfer etc.

What is HDI PCB ?

With the pace and spirit of technological innovations, so many electronic products are being manufactured by the use of these advanced PCBs. HDI PCB is one of the technologically competent PCBs. For basic understanding, HDI stands for High Density Interconnector. In case of HDI PCB, it has a higher wiring density per unit area as opposed to conventional board. More specifically, HDI PCBs have finer spaces and lines, minor vias, capture pads and higher connection pad density. Generally, an HDI PCB has a symmetrical structure. In case of Unsymmetrical structure, the process is more cost effective.

HDI PCB Manufacturing,

During HDI PCB Manufacturing, to achieve the HDI, it is taken care that the circuit board must have the extreme small PCB vias and fine traces. Each HDI PCB consists of inner and outer layers. The inner layers are the symmetry axis part of the PCB and more specifically, this part is penetrated by buried vias. The outer layers clamp the inner layers. The process of HDI PCB manufacturing differs based on the HDI builds. But the common manufacturing is sequential laminating. Besides sequential laminating, technologies for creating stacked vias and in-hole metallization are also very important in use.

In the end, it can be said that the process of manufacturing of HDI PCB is very important for getting the customized requirement. At the same time, a reliable HDI PCB manufacturer is equally important to be chosen.
