Multilayer PCB

For PCB quotations, while simple single-sided or double-sided PCBs can be roughly estimated using PDF or JPG files, it is challenging to provide accurate quotes for complex multilayer PCBs with more than four layers. PDF and JPG formats are insufficient for PCB fabrication, as only PCB format files or Gerber files are suitable. If PCB files are unavailable, PCB samples can be used to generate Gerber files. PCB designs should be created using common software like Protel DXP, Powerpcb, or PADS, and the files must be in formats such as PCB, ODB, Gerber, or DWG. Additionally, specifications like board thickness, copper thickness, solder mask color, and surface treatment must be provided for accurate quotations or production. It's also important to verify the manufacturing capacity of the PCB provider to avoid potential production issues. Read More

In the world of electronics, printed circuit boards (PCBs) are essential components that serve as the backbone for electronic devices. Among the various types of PCBs, multilayer PCBs have gained significant attention due to their unique advantages and applications. Read More

The thickness of a multilayer PCB is determined by the selection of copper clad laminate (CCL), with consistency in the thickness and alignment of CCL and prepreg being crucial to prevent bending, especially in boards with more than six layers. Historically, electronic components were mounted on metal chassis with conductive wires, but advancements in printed circuit technology have shifted this to PCB-based assemblies, offering better electrical performance, higher reliability, smaller size, lower cost, and automated production. Multilayer PCBs, consisting of three or more layers interconnected by metalized holes, are used in large computer systems and electronic devices, with the technology evolving alongside microelectronics assembly techniques.

Aluminum PCBs, compared to traditional FR4 PCBs, can carry higher current with the same thickness and line width. The key component of aluminum PCBs is the insulation layer, which provides adhesion, insulation, and thermal conductivity. The structure of a single-sided aluminum PCB includes a circuit layer, an insulating layer, and a metal layer. For more complex applications, there are two-layer and multilayer aluminum PCBs. The insulation layer's thermal conductivity is crucial for heat dissipation, which helps reduce device operating temperatures, increase power load, reduce volume, extend service life, and improve power output.

The text outlines various types of positioning holes used in the PCB production process, such as pressing positioning holes, mechanical drilling position holes, and copper plating inspecting holes. These holes serve different functions, including aligning layers, positioning for drilling and soldermask application, and ensuring the integrity of copper plating. The document highlights that these positioning holes are used in the production panel by the PCB supplier and do not appear in individual PCBs, with exceptions for special processing boards like HDI and laser drilling PCBs.

PCB manufacturers often face challenges when customers request quotations based on PDF or JPG files, which are inadequate for accurate pricing of complex multilayer PCBs and cannot be used for fabrication. Accurate quotations and fabrication require PCB format files or Gerber files generated by common design software like Protel DXP, Powerpcb, or PADS. Manufacturers also need detailed PCB specifications, including board thickness, copper thickness, solder mask color, and surface treatment. If PCB files are unavailable, manufacturers can create Gerber files from physical PCB samples for production. Read More
