PCB board is basically composed of aperture hole layer, DRILL layer, circuit layer, solder mask layer and character layer. In CAM350, each loaded layer will be distinguished by different colors, so as to facilitate The engineering of the circuit board factory is actually operated by the person who holds the position.

As the PCB size requirements become smaller and higher, the device density requirements become higher and higher, and the PCB design becomes more and more difficult. How to achieve a high PCB routing rate and shorten the design time, let's talk about the design skills of PCB planning, layout and routing.

What are the common problems of PCB circuit board production line, solder mask and text. The printed board is also still for a certain period of time, so that the gas in the ink on the surface of the board gradually evaporates with the flow of the ink, and then take it out. Go to a certain temperature to bake.

The average number of layers of PCB multilayer boards has become an important technical indicator to measure the technical level and product structure of PCB enterprises. This paper briefly describes the main processing difficulties encountered in the production of multi-layer circuit board proofing, and introduces the control points of the key production process of high-level circuit boards.

If the line width is too small, the resistance of the wires just printed will be large, and the voltage drop on the line will be large, which will affect the performance of the circuit. If the line width is too wide, the wiring density will not be high, and the board area will increase. In addition to increasing the cost, it is not conducive to miniaturization.

The copper wire of the PCB falls off (that is, the copper is often said to be thrown away), and each PCB brand will infer that it is the problem of the laminate, requiring its production factory to bear the bad losses. According to years of experience in handling customer complaints, the common reasons for PCB copper rejection are as follows

Now more and more electronics companies have begun to carry out pcb board proofing personalized customization services. There is no fixed range in price. It needs to be customized according to the size, quantity, process, special process, delivery time and packaging type of the circuit board you need. Wait to determine the price, then, with so many customized circuit board companies, how to find a customized PCB circuit board company that suits you?

Electroless Plating Copper is commonly known as immersion copper. Circuit board hole metallization technology is one of the keys to printed circuit board manufacturing technology. Strictly controlling the quality of hole metallization is the premise to ensure the quality of the final product, while controlling the quality of the copper immersion layer is the key. The routine test control methods are as follows

PCSPCB is a production enterprise specializing in single- and double-sided circuit boards and aluminum-based circuit boards. It has a factory building of more than 50,000 square meters and a complete set of advanced automatic circuit board production equipment. The annual output of circuit boards is more than 100,000 square meters. Enterprises in temperature control instruments, automation instruments, LED lights, car lights, electric vehicle accessories, communication equipment, electrical appliances, electronics and electric power industries produce supporting circuit board products.

As circuit designs are shared more widely and internal teams increasingly rely on reference designs, basic rules like the above will remain a feature of printed circuit board design, which we believe is important for pcb circuit board proofing designs. Even if you're new to circuit board design, keeping these basic rules in mind will speed up the learning process and boost your confidence.

Prior to the start of production, the audit engineer will find these errors in time, which sometimes leads to a delay in the PCB assembly process while the customer corrects the problem. Thus, some of the most common problems found in years of experience working with Gerber files. Expect the customer to be correct before submitting the quotation.

With the continuous improvement of human requirements for the living environment, the environmental problems involved in the production process of PCB manufacturers are particularly prominent. The topic of lead and bromine is the most popular, and lead-free and halogen-free will affect the development of PCB boards in many ways.

The printed circuit board is the support body of electronic components and the carrier of electrical connection of electronic components. Before the appearance of PCB, the connection between electronic components was completed by direct connection of wires; Today, the wire connection method is only used in laboratory tests, and PCB has occupied an absolute control position in the electronics industry.

Do PCB board is to design the schematic into a real PCB circuit board, please do not underestimate this process, there are a lot of things that work in principle in the project is difficult to achieve, or others can achieve things other people can not achieve, so it is not difficult to do a PCB board, but to do a PCB board is not an easy thing.

PCB Multilayer printed circuit boards are the basis of electronic devices. The increase in circuit density and the trend of decreasing the size of electronic products have led to the development of higher complexity of circuit boards. These holes or through-holes are responsible for the electrical connections between the layers and the corresponding functions that the board will perform according to the design requirements, which will not function effectively unless they are properly designed or manufactured.

PCB The process of multi-layer circuit boards begins with the selection of the right material. Choosing the right laminate is crucial because it determines stability, lower losses, and optimal performance for the final assembly. Several laminate materials are available to support the assembly of printed circuit boards.
