As electronic devices shrink in size and their designs become more complex, the need for small PCB with precisely placed largest components is increasing. This is driving demand for tools and technology that can improve the accuracy of such small, complex parts. This is why high density interconnect (HDI) technology expands the scope of this market segment. The technology allows the construction of extremely dense panels with a very large number of components per square inch that can be effectively installed. This article explores the growth and benefits of HDI PCB manufacturing.

The significance of using HDI PCB manufacturing

Typically, PCBS have one or two layers. Multilayer PCBS can have anywhere from 3 to 20 layers, depending on the application and its complexity. HDI PCBS can even have 40 layers and have precisely mounted components, thin lines and microholes in a compact space. You can identify them by their thin lines. HDI PCB manufacturing has also achieved success in other areas. Here are some of them:

With HDI, you can have multiple permutations and layer combinations. Although cores are part of the PCB layer design, and they are shown in the diagram, HDI can achieve a core-free design. You can have two or more HDI through hole layers, as well as through holes through buried holes, with many types of HDI boards. Follow the through-hole pad process for maximum assembly with minimum number of layers. If you compare this to the usual through-hole technique, you can reach 8 layers with the help of 4 layers of HDI. Using HDI, designers can more easily fit small components very tightly into compact Spaces. In addition to conventional consumer electronics and automobiles, HDI PCBS are especially useful in mission-critical applications, such as defense aircraft and medical equipment.

This is a representative diagram of HDI layering on an eight-layer PCB: Benefits of HDI technology, HDI provides many benefits to the PCB as well as the product as a whole. Here are a few: Without a doubt, HDI technology provides the highest accuracy. HDI PCBS have better signal speeds and relatively low signal losses compared to previous technologies. With advanced machining, you can drill holes to the smallest size, while with HDI, you can accurately produce the inner and outer layers in the most compact PCB space. With HDI, you can have very small cores and very fine drilling. You can achieve tight hole tolerances and controlled depth drilling. Microbore may be small, with a maximum diameter of 0.005. In the long run, HDI PCB manufacturing is cost-effective because it reduces the number of layers. Overall, it enhances the electrical performance of the equipment. If you are assembling HDI PCBS for industrial applications, be sure to contact a known PCB manufacturer who will understand your requirements and customize them accordingly.
