PCBWay is the best supplier in the PCB field and provides different services for their clients worldwide. This PCB supplier is providing different services for PCB-based and PCBA for their clients. They not only provide boards but also introduce new features and services for their users. In this post, we will cover PCBWay’s 24-layer, 6-order arbitrary interconnection HDI PCB.
PCBWay’s 24-Layer, 6-Order Arbitrary Interconnection HDI PCB
- With the regular growth of the ICS industry, the connection for chips is increasingly becoming complicated.
- Conventional board technology also has limitations in its different uses for high-frequency and speed features.
- There is a need for a stable connection between high-speed and high-density chips.
- The power use of chips also increases heat production and requires an effective cooling system for handling the normal working of chips.
- So the use of an interposer board that is a new PCB type is made for handling previous issues.
Interposer PCB Features
- The interposer board is a precise and high-layer interconnection HDI board. It is important for the connection and configuration of different components and works like bridge layers for the connection of chips.
- It provides an electrical connection through pad leads and connects with chip micro bumps and routing in central layers.
- The intermediary layers use silicon vias for the connection of the top and lower layers.
- The design features of this type of PCB are inner layers connected with external layers with the use of laser micro vias, and dense routing causes multi-design through BGA connection at the upper side and pad connection on the lower part.
Importance of Interposer Boards
- The interposer board comes with high value and importance for increasing different features for ICs.
- Interpose board has high connection speeds and is reliable for semiconductor devices. They are made for high-performance materials; interposer boards make short-distance, high-density connections for ICs and provide high-chip data transmission.
- These boards also have high-quality signal integration and power uses. With the use of interposer techniques, signals pass directly connected with interposer layers, minimizing the length of the signal transmission path and also having fewer signal losses and increasing the quality of the signal.
- The interposer layers are also used for thermal management features and to minimize chip temperature. Using ICS with different operations on the same interposer layers helps to make connections between different chips and increases the working performance and efficiency of semiconductor products.
- PCBWAY is a famous high-end HDI board services provider. That followed the market conditions, and as a result of certain needs for high-order arbitrary interconnection (Anylayer), HDI boards and their proper research helped to handle technical issues for getting proper growth of high layers and high-order arbitrary interconnection interposer PCBs.

Challenge 1:
- The buried vias board thickness from L7 to L8 is 1mm and the mechanical through hole diameter is 0.1mm and provides hole aspect ratio of 10:1, which makes mechanical drilling difficult.
Challenge 2:
- The BGA pitch is 0.35mm and the distance from the hole to the conductor trace is 0.13mm and easy for misalignment during multiple laminations.
Challenge 3:
- The trace width is 2.4/3mil and comes with dense routing here you can see some routings

Conclusion
An interposer board is commonly used where high-performance computing, artificial intelligence, data centers, and communications systems are needed. For high-performance computing systems, interposer techniques make the connections of different processing chips and provide larger-scale computing features.
AI interposer technology helps interconnections between different chips and increases interference speed for neural systems. For data centers and communication, interposers provide high transmission rates and bandwidth to fulfill the requirements for larger data processing and high-speed communication.
