Optical module Board / EM528K CCL / ENEPIG treatment
HDI boards are appropriate for a wide range of industries. As
mentioned above, you'll find them in all types of digital devices,
like smartphones and tablets, where miniaturization is key to the
effective application of the product. You can also find
high-density interconnect PCBs in automobiles, aircraft and other
vehicles that rely on electronics.
One of the most critical areas where the high-density PCB is making
huge inroads is in the medical arena. Medical devices frequently
need small packages with high transmission rates that only HDI PCBs
can supply. For example, an implant needs to be small enough to fit
in the human body, but any electronics involved in that implant
absolutely must efficiently allow for high-speed signal
transmission. Here, the HDI PCB indeed is a godsend. HDI PCBs can
also be useful in other medical equipment, like emergency room
monitors, CT scans and much more.
1 . Descriptions:
What is a HDI PCB?
HDI stands for High Density Interconnector. A circuit board which
has a higher wiring density per unit area as opposed to
conventional board is called as HDI PCB. HDI PCBs have finer spaces
and lines, minor vias and capture pads and higher connection pad
density. It is helpful in enhancing electrical performance and
reduction in weight and size of the equipment. HDI PCB is the
better option for high-layer count and costly laminated boards.
Regarding the electrical needs of high-speed signal, the board
should have various features i.e. high-frequency transmission
capability, impedance control, decreases redundant radiation, etc.
The board should be enhanced in the density because of the
miniaturization and arrays of the electronic parts. In addition, to
the result of the assembling techniques of leadless, fine pitch
package and direct chip bonding, the board is even featured with
exceptional high-density.
Innumerable benefits are associated with HDI PCB, like high speed,
small size and high frequency. It is the primary part of portable
computers, personal computers, and mobile phones. Currently, HDI
PCB is extensively used in other end user products i.e. as MP3
players and game consoles, etc.

3. Advantages:
The most common reason for using HDI technology is a significant
increase in packaging density. The space obtained by finer track
structures is available for components. Besides, overall space
requirements are reduced will result in smaller board sizes and
fewer layers.
Usually FPGA or BGA are available with 1mm or less spacing. HDI
technology makes routing and connection easy, especially when
routing between pins.
