HDI Multilayer PCB Board Making With 4 Layers With IATF16949 Communication PCB Assembly

The Definition Of PCB

Printed circuit board (PCB) is a printed board that forms point-to-point connections and printed components according to a predetermined design on a common substrate.
The main functions are as follows:
1) Provide mechanical support for various components in the circuit;
2) The electrical connection of various electronic components to form a predetermined circuit plays a relay transmission role;
3) Mark the installed components with mark symbols to facilitate insertion, inspection and debugging.

The Definition Of HDI​ PCB

HDI PCBS have high density properties, including laser micropores, sequential laminated structures, thin wires, and high-performance thin materials. This increased density allows for more functions per unit area. Advanced technology HDI PCBS feature multiple layers of copper-filled stacked microholes, a structure that enables more complex interconnections. These complex structures provide the necessary routing and signal integrity solutions for the large pin count, fine pitch, and high-speed chips found in today's high-tech products.

Differences Between HDI And Standard PCB

HDI essentially provides better signal integrity performance than non-HDI because all stray capacitors and inductors are reduced when using small blind and buried holes. Since there are no stubs, the impedance of the microhole is close to the linear impedance. The stray capacitance of a normal pass hole is much higher, which results in a greater impedance discontinuity than a micropass hole.
