High-Density Interconnection (HDI) board is one of the key technologies driving advancements in PCB electronics. Through its multiple via processes, HDI technology minimizes the number of layers, making for smaller yet more powerful PCB circuitry.
HDI, or High-Density Interconnection, is a PCB technology that emerged around the end of the 20th century. The advantages it holds over the traditional PCBs fueled its popularity tremendously.
HDI PCB by laser drilling technology. That precludes the drawbacks you face when using the traditional mechanical drilling technology, including higher cost and improvement difficulties.
HDI PCB fabrication deploys advanced multilayer technology which allows you to integrate multiple layers to create a multilayered PCB. https://www.wellpcb.com/hdi-pcb.html

There are numerous benefits that HDI PCB offers. These include a smaller surface area, higher speed of transmission as well as a high frequency. Their small size enables them to be used in hi-tech devices such as computers, phones, and consoles etcetera.
They allow for innovation and miniaturization of products.
It ensures lesser thermal stress and adds to the durability of the PCB.https://www.ourpcb.com/hdi-pcb.html
