As the name implies, rigid-flexible printed circuit boards are manufactured by the combination of rigid and flexible circuit boards. The two boards are then permanently interconnected to form various types of PCBs. In the manufacturing process of rigid and flexible circuit board, some factors and precision must be considered to produce the perfect final product. […]

With the rapid development of electronic technology, PCB manufacturers can only find a way out in the highly competitive PCB industry by actively developing and innovating production technology on the basis of recognizing the development trend of PCB technology. PCB manufacturers should always keep a sense of development. Here are some views on the development […]

Consideration of the aperture size of PCB proofing pad When PCB proofing plug-in component pads, the pad size should be appropriate. If the pad is too large, the solder spreading area will be larger, and the solder joints formed will not be full, while the copper foil surface tension of the smaller pad will be […]

There are many kinds of resistors, such as carbon film resistor, cement resistor, metal film resistor and wire wound resistor. Special resistors include piezoresistors, thermistors and photoresistors. Different types of resistors have certain differences in their characteristic parameters, and the points to be considered in circuit use are also different. For engineers who are new […]

In PCB proofing, a layer of lead-tin resist is pre-plated on the part of the copper foil that needs to be kept on the outer layer of the board, that is, the graphic part of the circuit, and then the rest of the copper foil is etched away chemically, which is called etching. As the […]

1. print PCB circuit board. Print the drawn circuit board with transfer paper, and pay attention to the slippery side facing yourself. Generally, two circuit boards are printed, that is, two circuit boards are printed on a piece of paper. Among them, the printed circuit board with the best printing effect is selected. 2. Cut […]

Circuit board, which can be regarded as a miniature bearing platform, is an important carrier of integrated circuit. The appearance of PCB multilayer board allows the limited space to accommodate more and more complex circuits as much as possible. In addition, it also simplifies the difficulty of circuit layout on PCB to some extent. Many […]

Introduction of Ink and Its Main Properties in Xi ‘an PCB Manufacturing Factory It also plays a very important role in the production process of printed circuit board in printing ink pcb board factory. Today, Xi ‘an PCB Manufacturing Xiaobian introduces the composition and main performance of ink. The printing ink of Xi ‘an PCB […]

Process introduction and technical points analysis of copper deposition process for evi circuit boards Chemical copper is widely used in the production and processing of printed circuit boards with through holes. Its main purpose is to deposit a layer of copper on the non-conductive substrate through a series of chemical treatment methods, and then thicken […]

PCB proofing production is developing in the direction of high density, high precision, fine aperture, fine wire, fine pitch, high reliability, multilayer, high-speed transmission, light weight and thinness. At the same time, production is developing in the direction of increasing productivity, reducing cost and pollution, and adapting to multi-variety and small batch production. The technical […]
