For buyers who choose PCB boards, the selection of boards must not only depend on the price and the quotation of the circuit board factory. It is crucial to understand the characteristics of the boards and the prices of different types of boards. The above is a brief discussion by Jiali Chuang on good PCB circuit board manufacturing factories. When choosing pcb board manufacturing factories, it is important to choose some high-performance boards, otherwise the competitiveness of the industry will be quickly stimulated.
When choosing a PCB circuit board manufacturing factory, it is necessary to choose whether there is a need for high-quality and professional production personnel, professional production personnel, and a reasonable operating team. It is necessary to not only understand and control production costs reasonably and effectively, but also quickly familiarize oneself with the production process, have a sense of responsibility and teamwork.

In the layout design of circuit boards, consider as much as possible all issues such as line width, spacing, solder pads, and through holes that are not accessible;

Properly orient the edges of plugs, sockets, and heat sinks that I commonly use to ensure that all wiring is on the same side as much as possible, in order to provide the best electrical equipment and heat dissipation efficiency.
The time from electric heating to heat dissipation should not be too long, mainly to prevent electric shock and heat. When it comes to heat dissipation, it should range from a few milliamperes to several hundred milliamperes, to multiple milliamperes, and then to tens of milliamperes. If semiconductor devices are connected.
When designing circuit boards, thermal design should consider safety. If the circuit board design is incorrect, heat will directly enter the circuit board and cause the circuit to burn out. Therefore, thermal design needs to be cautious. Usually, design engineers need to take effective measures during the design phase to design circuit boards to achieve a safe level, while also ensuring that devices can work reliably.
According to the functional units of the circuit, when laying out all components of the circuit, in addition to considering the parasitic parameters of the structure itself, it is also necessary to consider the worst-case power supply current of the components used.
Power requirements generally try to connect some inductive loads at the power supply end of the device, such as optocouplers, common mode inductors, high-frequency switching power supplies, induction motor starting circuits, etc.
For single point power supply modules, full consideration must be given to their operating environment temperature, with sufficient margin left; If the product has processed the induction wire, flat wire, zero wire, and switching power supply through the product's machining process, and still pays attention to the stability impact of the product's machining process on the entire machine, it is necessary to strictly follow the regulations of the product's machining process during the use of the machining process to avoid the occurrence of a "strike" situation; At the same time, there may be product machining accidents during production during the machining process. Once this phenomenon occurs, medical measures should be taken to avoid or reduce the possibility of machine self destruction.
The icHub Health Risk Assessment Agency has learned that the health risk assessment mechanism confirmation released by Xinlu shows that the testing mechanism confirmation shows that in addition to the icHub health risk assessment mechanism confirmation provided by the customer, the health risk assessment mechanism confirmation shows that in addition to the icHub health risk assessment mechanism confirmation provided by the customer, the health risk assessment mechanism confirmation also provides the health risk assessment mechanism confirmation, According to the confirmation of the icHub health risk assessment mechanism provided by the customer, SY18 did not pass the RITUTECH test and supports the verification.
