HDI boards, one of the fastest growing technologies in PCBs. HDI Boards contain blind and/or buried vias and often contain microvias of .006 or less in diameter. They have a higher circuitry density than traditional circuit boards. There are 6 different types of HDI boards, through vias from surface to surface, with buried vias and through vias, two or more HDI layer with through vias, passive substrate with no electrical connection, coreless construction using layer pairs and alternate constructions of coreless constructions using layer pairs.

PCB manufacturing has many applications, but we will introduce the 10 most common uses of printed circuit boards.

In general, the cost of raw materials accounts for 60% of the cost of PCB, and its price fluctuation cost has a great impact on the overall development of the PCB industry. PCB raw materials are a plate that can not be ignored by enterprises in the industry.

FPC, in fact, belongs to a kind of PCB, but it is quite different from the traditional printed circuit board.

With more density came more power dissipation and thus more heat generation. So a usual FR-4 based substrate PCB was not capable to withstand such high temperatures and thermal characteristics of FR-4 was not up to mark, hence the researchers found the solution in the form of "Ceramic PCB".

Lead-free PCBs (Printed Circuit Boards) were first called for just for the compliance of ROHS (Restriction Of Hazardous Substances) that requires all the electronics have to conform to ROHS regulations. As a result, PCB fabrication starts to convert from lead to lead-free.

It’s important to indicate that all the tips are summarized based on manufacturing experience in Rocket PCB’s workshop. Rocket PCB has been serving globe electronics for 14 years. Up to now, we’ve served more than 10,000 customers from over 80 countries and regions around the world with HIGH-RELIABILITY and LOW-COST bare PCBs and assembled PCBs that have been widely applied in numerous fields covering medical care, industrial control, transportation, military, aerospace, IoT etc.

The PCB industry is the industry with the largest output value in the global electronic component industry, and it is also the basic industry for electronic information product manufacturing. In 2019, affected by multiple factors, the global PCB industry output value fell slightly by 1.7% year-on-year to US$61.3 billion. Although COVID-19 impact on the industry, the rapid development of 5G has allowed the PCB industry to grow. It is estimated that the global PCB output value will be 62.5 billion US dollars in 2020 and reach 79.2 billion US dollars by 2025.

Although the current level of semiconductor integration is getting higher and higher, many applications also have system-on-chips available at any time, and many powerful and out-of-the-box development boards are also more and more easily available, but many use cases in electronic products The application still needs to use a custom PCB. In one-time development, even an ordinary PCB can play a very important role. PCB is the physical platform for design and the most flexible part for electronic system design of original components.

This article will take you to understand the basic knowledge of PCB process and manufacturing flow.

PCB manufacturing industry is a technology intensive industry with high technical barriers. PCB industry integrates electronics, machinery, computer, optics, materials, chemical engineering and other disciplines to engage in product manufacturing services.

As trade tensions between China and the U.S. intensify, the U.S. semiconductor industry is worried that the relationship between the two sides of the technology may damage the global supply chain. Now, companies on both sides of the Pacific are trying to develop risk reduction strategies - whether it's hoarding supplies or considering relocating production facilities.
