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 […]

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. […]
Pcb proofing and cutting dimensions ① Maximum panel size: 530 * 622mm (tinplate: 450 * 622mm/MAX. Depending on the equipment capacity) ② Pay attention to the latitude and longitude of boards with more than six floors (they must be the same), which will easily cause poor compression. ③ The size of the reserved surface of […]
Where are the OEM manufacturers in Changsha? Circuit board proofing refers to the trial production of printed circuit boards before mass production. It is mainly used in the process of small batch trial production in the factory after the electronic engineer designs the circuit board, that is, circuit board proofing. Generally, there is no specific […]
Metal core PCB is not very common in consumer products, but it can be found everywhere in industries, aerospace, lighting systems, power electronics and other fields that require high reliability. High-power systems generate a lot of heat, and it is necessary to quickly remove the heat to prevent component failure. Similarly, low-power systems may be […]
What problems should be paid attention to when PCB proofing components are used? In PCB proofing, components with high sensitive voltage threshold should be used as much as possible on the premise of meeting the requirements of circuit functions. Because the electrostatic and discharge sensitivity of a circuit board depends on the components with the […]
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 […]
Product name: 10-layer pcb production Introduction of 10-layer pcb board: PCB(Printed Circuit Board) is also called: circuit board, printed circuit board, printed circuit board, Almost all electronic devices can be used. As long as there are electronic components such as integrated circuits, printed boards should be used for their electrical interconnection. In the process of […]
