PCB Technical - ​Four-layer PCB blind hole board welding service

The wires on the circuit board are bent. Why should the PCB circuit board keep the process side? What are the technical difficulties of high-precision circuit boards? Why is the circuit board on the circuit board bent?

Why is the circuit soldered on the four-layer PCB blind board bent?

With the rapid development of modern technology, more and more electronic products in our lives are inseparable. We will find that there are some circuit boards in these electronic products, but the circuits on the circuit boards are too messy. The second is that the overlap of the two-level holes is similar to the two-level processing, but many technical points should be specially controlled. Why is the wire on the circuit board bent? It is completely incomprehensible for ordinary people. Can't the circuit of the circuit board be planned in a straight line?

First of all, if the lines in the four-layer PCB blind hole soldering are planned to be straight, the area of the circuit board will increase several times. In this era of pursuit of exquisiteness and compactness, the smaller the area of the circuit board, the better, and it will directly affect the area of electronic products. With the demand for electronic products, the structure of multi-layer circuit boards has become more and more complex. According to estimates, the requirements of electronic products are that, in addition to the larger the screen, the thinner the better.

Second, even if we don't care about the size of the blind hole soldering on the four-layer PCB, the lines in the circuit board will cause other problems. The wires on the circuit board must be turned. If we plan the lines on the circuit board as a straight line, the turning angle reaches 90 degrees. When the circuit is turned at 90 degrees, it is easy to reflect, and such a circuit board is easy to break during the production process. This not only causes a waste of data, but also prone to quality problems. Qixiang Electronics specializes in the production of high-precision multilayer circuit boards, providing you with four-layer PCB blind hole board welding, c-type circuit boards, digital circuit boards, power circuit boards, apple header circuit boards and other services. We have checked 36 test processes to ensure the quality of the products.

The wires on the circuit board are designed to be bent to ensure the stability of the signal. The planning of the circuit board is a technical task, and only the corresponding planning can ensure the stability of the signal. Only when the signal is not disturbed, the chip on the circuit board can work normally. Each curved line on the circuit board represents a different signal. If the lines on the circuit board are planned to be straight lines, it is easy to interfere with each other and make our electronic equipment unable to work normally.

The PCB circuit board is an important electronic component part of the electronic component support in the production process of the PCB circuit board. You need to leave a process edge on the PCB circuit board, so why solder a four-layer PCB blind board?

In fact, the first reason why the PCB circuit board left technology is that the auxiliary production plug-in soldering wave increases on both sides or four sides of the PCB circuit board. The first is auxiliary production. The parts that do not belong to the PCB circuit board can be removed after the production is completed.

The first reason why the PCB circuit board leaves the technology is that the trace of the SMT placement machine is used to clamp the PCB circuit board and flow through the patch machine. Therefore, when the SMT placement machine sucks in components and installs them on the PCB circuit board, the components that are too close to the track side cannot be produced. Therefore, it is necessary to reserve necessary processes, such as 2 to 5 mm. include. On-time delivery rate, customer satisfaction, actively taking responsibility for production errors, whether after-sales service is guaranteed, whether to provide online consultation or technical support, should be our selection criteria. It is also suitable for some plug-in parts to prevent similar phenomena through wave soldering.

The fineness of the PCB circuit board is very demanding, especially the trend and direction of each circuit must be controlled in a very small state. High-quality circuit board production capacity is closely related to its years of production experience, creating a higher degree and influence. Accumulated a relatively fixed consumer group. Therefore, the unusual CAT found in the excess drilling must be analyzed in time to propose corresponding technical countermeasures to repair the quality of CANE in time. So, what are the technical difficulties of circuit board production?

The degree of adaptability is higher than that of a variety of electronic products: The technical difficulties of circuit board production include the adaptability of electronic products. If the adaptability of the circuit board is not high, the model and size will be large. The production of 15mm advanced automatic compressor high-level circuit boards has automated production equipment within our process range. Only with high adaptability can the two parts match and the real function of electronic products can be brought into play.

The limit setting of carrying current: The technical difficulties of circuit board production also include the carrying capacity of current. Short circuit or circuit damage is easy to happen. If you also want to find a fast four-layer PCB blind hole soldering manufacturer, you are welcome to call Qixiang Electronics, and we will try our best to serve you. The designer must limit the current carrying limit of the circuit board, and pay attention to the limit of the circuit board according to the power of the electronic product.

Speed and efficiency of information transmission: The technical difficulties of PCB production also include the speed of information transmission, especially assuming that the efficiency of information transmission is low. Unable to receive information for a short time. In order to further increase the transmission rate of the circuit board, tests and calculations must be repeated to produce the required products.
