The performance of PCB companies and leading stocks is differentiated

With the upsurge of the copper-clad laminate market, the performance of listed PCB companies has further diverged. In particular, the data communication sector and rising raw material costs generally dragged down the semi-annual report. As a leading A-share PCB company, Shennan Circuits (002916) both declined in revenue and net profit in the first half of […]

PCB silkscreen specifications and requirements

PCB silkscreen specs and requirements 1. All components, mounting holes, and positioning holes have corresponding silkscreen marks. In order to facilitate the installation of the board, all components, mounting holes, and positioning holes have corresponding silkscreen marks. The mounting holes on the PCB use H1. H2…Hn for identification. 2. Silk-screen characters follow the principle of […]

Manufacturing process of super thick copper multilayer PCB

With the rapid development of power communication modules, 4-6OZ conventional thick copper has been difficult to meet its performance requirements, and the demand for super thick copper PCB of 10-12oz and above is getting higher and higher. This article is talking about 12oz super thick copper, a feasibility study was conducted on the production process […]

The demand and price of ABF carrier boards have soared

According to news on August 2nd, with the growth of the 5G, AI, and high-performance computing markets, the demand for IC substrates, especially the ABF substrates, has exploded. However, due to the limited production capacity of relevant suppliers, the demand for ABF substrates is in short supply. Prices have also continued to rise. The industry […]

Advantages and disadvantages of FPC

The flexible board is a printed circuit interconnection structure built on a bendable ultra-thin substrate material. They can be bent into a three-dimensional (3D) structure, which cannot be achieved by a rigid board. Due to this flexibility, the flexible board has more advantages than other connection methods and is more suitable for electronic devices that […]

FPC applications

FPC FPC (Flexible Printed Circuit) is a printed circuit board made of flexible copper clad laminate FCCL as the basic material. It has the advantages of a lightweight, thin thickness, small size, foldability, and high circuit density. It is widely used in smartphones, wearable devices, automotive electronics, medical equipment, industrial control equipment, and other modern […]
