12-layer VT-901 polyimide PCB Manufacturers

Printed circuit board (PCB), also known as printed circuit board, is a provider of electrical connection of electronic components

The environment in an industrial workshop is different from that of ordinary places, especially in production and processing workshops. Summer temperatures are already high, and combined with the heat dissipation from the machines, temperatures in the workshop often reach over 60°C, and in some cases even reach 80°C. The HDI PCB in industrial control equipment are the "brains" of the equipment. If they are not heat-resistant enough, problems can easily arise. These include circuit aging, component loss, and even direct short circuits. If the equipment stops, the entire production line will be affected.

With the rapid development of digital technology, electronic products are undergoing tremendous changes, especially in the mobile phone industry. As we all know, chips are the core components of smart phones, and the development of chip industry is related to the development of mobile phones and other electronic products.

Before designing multi-layer PCB, the designer needs to first determine the circuit board structure according to the scale of the circuit

What should be paid attention to in the anti-corrosion treatment of multilayer circuit boards

Substances and materials in nature can be divided into three categories: conductors, semiconductors and insulators according to their conductivity. The resistivity of semiconductor is in the range of 1m Ω· cm ~ 1g Ω· cm (the upper limit is taken according to Xie jiakui's electronic circuit, and 1/10 or 10 times of it; because the angle mark is not available, the current description is used temporarily)
