Printed circuit board (PCB) manufacturing technology continues to evolve to meet the demands of high-density, high-performance electronic devices. Among these, multi-level blind via PCBs (HDI<\/a>) has become a topic of great interest.<\/p>\n

This article will take an in-depth look at the design and manufacturing process of multi-layer blind-via printed circuit boards, as well as their market potential.<\/p>\n

\"Blind-Via<\/p>\n

Design and Fabrication Methods for Multi-Layer Blind-Via Printed Circuit Boards<\/h2>\n

Multi-layer blind-via printed circuit boards are typically designed and manufactured using high-density interconnect (HDI) technology.<\/p>\n

However, in the domestic PCB industry, some products still opt for multi-stage mechanical blind via board design and manufacturing. There are two main reasons behind this choice:<\/p>\n

1. Production Costs and Equipment Requirements<\/h3>\n

HDI Board<\/a>The manufacturing process places high demands on equipment and technical expertise; for example, it requires specialized equipment such as laser drilling machines, as well as advanced processes like electroplating for pore filling.<\/p>\n

These factors lead to increased costs for PCB manufacturers, which in turn affect product prices. For customers, cost control is an important consideration.<\/p>\n

2. Number of Pressing Cycles and Product Reliability<\/h3>\n

Some products are designed using the HDI method and manufactured using the lamination process, which increases the number of lamination cycles and reduces product reliability. In such cases, multi-stage mechanical blind via panels offer a more reliable alternative.<\/p>\n

Therefore, multi-layer mechanical blind via products still have market potential, and the manufacturing technology behind them remains valuable for many PCB manufacturers to learn from.<\/p>\n

Jingpeng Circuit's 10-Layer Blind-Via Board: A Technological Breakthrough<\/h2>\n

Jingpeng Circuit is committed to innovation in printed circuit board manufacturing technology, and the company has successfully developed a 10-layer blind-via board.<\/p>\n

The design and manufacturing of this product involve several key technical aspects, including the design of the manufacturing process, the design of the distance between the inner layer holes and the copper, and the control of expansion and contraction during the manufacturing process.<\/p>\n

Experiments have shown that by designing a reasonable PCB manufacturing process and optimizing the distance between inner-layer vias and copper, it is possible to effectively control product expansion and contraction, thereby preventing short circuits in the inner layers while ensuring excellent electrical performance.<\/p>\n

In addition, the implementation of solutions regarding panel curvature and copper thickness has yielded positive results in terms of panel curvature control and copper thickness characteristics.<\/p>\n
