In PCB proofing, rational and effective use of components is an important guarantee for the stability of PCB performance and quality. So, what problems should be paid attention to when using components in PCB proofing process? 1. PCB proofing limits the output current to avoid locking effect of CMOS circuit; Lock-in effect means that there […]

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 […]

In the electronic world, PCB or circuit board is the most indispensable part of any electronic equipment. Because they are hidden under the shell of electronic devices, they are often ignored, but they are indeed the backbone of any device, electronic products and equipment you own. PCB (Printed Circuit Board) houses all the electronic components […]

Multi-layer PCB is beneficial to products because they can handle greater complexity. Computers, telephones and medical equipment are some application examples that benefit from multi-layer design. However, the use of multilayer printed circuit boards will become a key problem to connect these layers to each other. If you don’t connect each layer to the corresponding […]

Overview of circuit board proofing Circuit board proofing, detachable understanding. PCB, that is, epoxy resin circuit board, proofing, that is, production of product samples. Therefore, PCB proofing, that is, before mass production of PCB circuit boards, commissioned manufacturers to make samples in order to confirm the feasibility of circuit design and product production plan, usually […]

Anti-oxidation of PCB is to coat the specified metal surface (hole and board) with an anti-oxidation organic film, namely organic solderability protection (DSP). Glicoat SMDLF2 is one of them, which maintains its solderability in the thermal cycle of forming a firm leveling technology on the metal surface of the printed board through the chemical reaction […]
