At present, domestic PCB manufacturers that can mass produce high-level circuit boards mainly come from foreign-funded enterprises or a few domestic-funded enterprises. The production of high-level circuit boards not only requires high investment in technology and equipment, but also requires the experience accumulation of technicians and production personnel. At the same time, the customer certification […]

The success or failure of ink use directly affects the overall technical requirements and quality indicators of PCB shipment. Therefore, PCB manufacturers attach great importance to the performance of ink. Besides the well-known viscosity of ink, the thixotropy of ink is often ignored by people. But it plays an important role in the effect of […]

A good circuit board should not only realize the function of circuit principle, but also consider the electrical characteristics such as EMI, EMC, ESD (electrostatic discharge), signal integrity, as well as the heat dissipation of mechanical structure and high power consumption chips. On this basis, consider the beauty of the circuit board, just like artistic […]

From the continuous update and development of computers, mobile phones and other electrical products, we can see the development of PCB manufacturing industry. HDI board making is the inevitable product of PCB development and a trend of PCB making. It is different from traditional PCB and has the following obvious characteristics: 1. Laser drilling is […]

Different types of PCB have different manufacturing methods, and the same type of PCB also has different processing methods. Although there are many manufacturing processes, they can be classified into the following three basic methods: Additive process: Through screen printing or exposure to form patterns, drilling, copper deposition, transfer lamination and other processing, the conductive […]

EMI is caused by electromagnetic interference source transferring energy to sensitive system through coupling path. It includes three basic forms: conduction through wires or common ground wires, space radiation or near-field coupling. The harm of EMI is to reduce the quality of transmission signal, cause interference or even damage to the circuit or equipment, and […]

Ultra-thick copper multilayer PCB originated from North America, such as UPE Company in Canada. In the 1990s, the company began to develop and produce ultra-thick copper multilayer PCB, and achieved good results. This kind of special board product is applied to the components connected with strong current and mixed connection of strong and weak current. […]

1, PCB painting outsourcing production requirements Clear requirements for plate thickness, copper thickness, welding resistance, character color, etc. The above requirements are the basis for making a board, so R&D engineers must write clearly. As far as the customers I have contacted are concerned, Gree has done a relatively good job, and the technical requirements […]

As HDI board adapts to the development of high integration IC and high density interconnection assembly technology, it pushes PCB manufacturing technology to a new level and becomes one of the biggest hot spots in PCB manufacturing technology!In all kinds of PCB cam production, the personnel engaged in cam production agree that HDI mobile phone […]
