If you had gone through different articles on this topic then definitely you will have a basic understanding of various types of PCBs, how to audit PCB manufacturers, various PCB design software that is available in the market, and everything about PCB Fabrication on how you can make the most from your money.

In this article, we will have a better understanding of core PCB manufacturing processes. In this series of articles, you will get to know the fundamental concepts of each process. Once you go through the complete cycle, we will jump on to the next series of articles in which we will get to have a deep understanding of its design and some manufacturing-specific problems and will learn different techniques to avoid them.

Density is the ratio of traces, holes, and pads by area unit. Density is not a problem when there is a presence of few traces. But modern density demands modern solutions and every day, the customers and the factories want more compact and more complex designs and this is basically due to the component technologies. And this is quite challenging.

It is very much obvious that when you want more density on a PCB Fabrication, you have to reduce the size of the lines, the size of the vias, spaces, and holes, and you must increase the number of layers, the number of connections, and also improve the routing on layers. It’s very easy to learn, but it is possible only because of pure science and technology. Complexity arises in the PCB if the density is very high. The market is trending to increase the density for many years.

If you carry out the concept to its limits, you will have a High-Density Interconnect PCB. High technology and complex processes never indicate the rise in costs.

For HDI PCB Fabrication, it is the opposite because in this case, the cost of the material is much more important than the cost of the density. If the traces and connections are more then it becomes less expensive. You pay much more because the material is very much expensive and because the process is very much complex.
