Advanced PCBs are commonly used in high-precision electronic devices. With the continuous development of technology, the demand is also getting higher and higher. To this end, the separate advanced PCB production workshop is opened to assist our customers achieve the best possible time to market and competitive advantage by producing PCBs in a sustainable way at the lowest total price through our fabrication capabilities, delivery punctuality and product quality.
What is HDI PCB
High density interconnects (HDI) PCB is characterized by high density features, including laser micro vias, fine lines, and high-performance thin materials. This increased density can support more functions per unit area. because of its higher circuit density than normal PCBs, the design of HDI PCB can incorporate finer lines and spacing, smaller through holes and pads, and higher connection with pad density. HDI PCBs have blind vias and buried vias, and generally contain micro vias with a diameter of 0.006 or less.
By using HDI technology, designers now can place more components on both sides of the raw PCB if desired. Now as the development of via in pad and blind via technology, it allows designers to place smaller components closer together. This means faster transmission of signals and a significant reduction in signal loss and crossing delays.
HDI PCB is frequently found in mobile phones, touch-screen devices, laptop computers, digital cameras, 4G network communications, also prominently featured in medical devices.
The advantages and applications of HDI technology.
-Compact design
The combination of micro vias, blind vias, and buried vias greatly reduces board space. With the support of HDI technology, a standard 8-layer through-hole PCB can be simplified into a 4-layer HDI PCB but with the same functions.
The birth of HDI PCB brings more possibilities for portable electronic devices and also brings more challenges to PCB manufacturers. In order to adapt to the miniaturization and multi-function trend of electronic products, AFASTPCB has made a lot of efforts to improve the level of equipment and the professional level of employees. You can provide us with HDI design, we will provide you with satisfactory services and HDI products.
