HDI PCB comes in different types with same functions. The type you decide to choose depends on the application you are using. Following are the different types of HDI PCBs.

• • Rigid HDI PCB:
    HDI PCBs are made of a solid and rigid substrate material such as fiberglass. This kind of material prevents the bending of the HDI board. The application of this HDI PCB can be found on towers of most desktops.
  • Rigid-Flex HDI PCB:
    This is made of a rigid circuit board, which attaches to a flexible board. The design’s complexity depends on whatever application you are using.
  • Flex HDI PCB:
    Flex HDI PCB is composed of flexible plastic. This material permits the board to form different shapes. This offers lots of benefits when compared with rigid boards. The board’s flexibility also allows you to move or bend easily during the process of application without bringing damage to the circuits that are present on the board. One disadvantage with this board type is that designing and manufacturing it costs a lot. However, they come with numerous benefits. The heavy wiring found in advanced equipment like satellites can be replaced with flexible HDI PCBs. They are lighter and make use of little space, making them great for such use. Another benefit is that it features different designs like multilayer, single-sided, or double-sided designs.
  • Multilayer HDI PCB:
    These boards have substrate boards of multiple layers with an insulating material that separates these layers. Just like HDI PCBs with double sides, either vias or through holes can be used in connecting the board’s electric circuits. Multilayer HDI PCBs are very beneficial because they use less space. Standard applications using this HDI board type include medical machinery, servers, handheld devices, and computers.
