High Density Interconnect PCBs
High density interconnect (HDI) is a technology that is rapidly becoming popular in PCB design and various electronic product integrations. HDI is a technology that offers a more denser construction on the board by placing smaller components in a closer position, which also leads to shorter paths between components.
HDI PCBs are finding their way into a growing number of products:
a.Aerospace - smaller space requirements and light weight are ideal for such applications.
b.Computers and mobile phones - by integrating HDI circuit boards, phones and computers are able to be more smaller with reduced weight and increased functionality.
c.Medical equipment –supported by advanced software and HDI PCBs, diagnostic and monitoring equipment has become more reliable and extended with technical features that aid medical teams with patient treatment.
d.Military communications devices and other strategic equipment.
Designing PCBs for HDI applications requires specific tools, so does the manufacturing process. Computer-aided design (CAD) software and computer-aided manufacturing (CAM) tools are considered mandatory when using HDI technology for PCB creation.
Training design engineers is also time-consuming as HDI is becoming more common in PCB and electronics market, but the payback in efficiency and reduction in rework and manufacturing delays is worth the investment.
