The imbalance between the ownership of HDI production capacity and the ownership of manufacturing site demands that domestic manufacturers have the right to speak. The distribution proportion of global HDI manufacturing sites and the country of affiliation is not matched. According to the classification of manufacturing sites, the production capacity distribution of Hong Kong, China and mainland China accounts for 59%, while only 17% according to the location of affiliation. On the one hand, the main downstream of HDI comes from mobile phones, and a relatively complete mobile phone component industry chain has been formed in China. The manufacturing location of   HDI is consistent with the industrial chain location , leading to the production capacity layout of most overseas manufacturers in Hong Kong and mainland China. There is a mismatch between the distribution of production capacity and the location of production capacity, so it is urgent for domestic manufacturers to improve ...

The rapid expansion of the automotive PCB market  In terms of automotive PCB, five major automotive electronic systems, such as power engine control system, body control safety system, on-board communication system, indoor installation system and lighting system, promote the upgrading of PCB system. At present, automobile PCB is mainly composed of 4-6 layers, accounting for 51%. On-board entertainment, new energy vehicles and millimeter wave radar will pull up the proportion of HDI, thick copper board and high-frequency board. Auto sales are picking up, and the trend of automobile electronic and new energy vehicle penetration resonates, driving the rapid expansion of the automotive PCB market.   The trend of terminal high density promotes HDI penetration, and the layout of domestic manufacturers is accelerated. HDI is one of the fastest growing circuits in PCB application. HDI's high integration and downstream customers are mainly mobile terminal products and computer pro...

There are many kinds of raw materials needed for PCB production, mainly including copper clad plate (CCL), semi-cured sheet (PP), copper foil, copper ball, gold salt, ink, dry film and other materials. Generally speaking, in the cost composition of PCB, about 37% is the copper clad plate, 13% the semi-cured sheet, 8% the gold salt, 5% the copper foil copper ball. The ratio of labor cost is relatively high, about 11%, and the ratio of raw materials of different types of products is slightly adjusted. According to the different thickness of copper clad plate, the cost of glass fiber cloth accounts for 25% ~ 40% of the cost, the cost of resin accounts for 25% ~ 30%, and the cost of copper foil 30% ~ 50%.   The rising price puts enormous pressure on PCB companies Data show that the Shanghai copper index has risen by more than 32% since 2021, and is now up to more than 70,000 points, at a new ten-year high position. In addition, glass fiber and resin prices are also at a high level. It ...

The Printed Circuit Board (PCB) is essential in electronic products, which are used either for domestic use or for industrial purposes. PCB design services are used to design the electronic circuits. Apart from electrically connecting, it also gives mechanical support to the electrical components. However, it is reported that the recent surge in raw material prices has led to rising costs in the PCB industry.  

Lead Free HASL PCB Product Description HASL is the predominant surface finish used in the industry. The process consists of immersing circuit boards in a molten pot of a tin/lead alloy and then removing the excess solder by using 'air knives', which blow hot air across the surface of the board. One of the unintended benefits of the HASL process is that it will expose the Printed Circuit Board  to temperatures up to 265°C which will identify any potential decontamination  issues well before any expensive components are attached to the board. Application area: Security Product feature: Peelable S/M Layer: 2 Surface treatment: Lead Free HASL Material: FR4 Line width/Line space: 0.325/0.305mm Thickness: 1.6mm Min hole φ: 0.75mm C hoosing a PCB surface finish  that works best for you and your process while still keeping the environment safe is has become a much more practical solution.
