The function of PCBA nano waterproof agent can be understood as PCB nano waterproof coating, PCBA nano moisture-proof coating and salt spray corrosion resistant coating, which provides a better solution for PCBA waterproof of electronic products.
The correct installation and layout of components on PCB is a very important step to reduce welding defects.
In order to print the solder paste, the PCB assembly board without soldering can not fix the test end of thermocouple, so it is necessary to use the actual product to test.
IPC-ESD-2020 Joint standard for electrostatic discharge control program development. It includes the design, establishment, implementation and maintenance of ESD control program.
Matching the impedance of the transmission line or the source of the load. According to the access mode, the impedance matching can be divided into two modes: serial and parallel; according to the frequency impedance matching of signal source, it can be divided into low frequency and high frequency.
We all know that electronic equipment will produce a certain amount of heat when working, and if PCB board is always in high temperature, it may make the components on the PCB board fail due to overheating.
We will encounter a variety of safe spacing problems in the normal PCB design, such as the spacing between vias and pads, the spacing between wiring and wiring, etc., which should be considered.
Because the layers in PCB are closely combined, it is not easy to see the actual number. However, if we observe the Banka fault carefully, we can still distinguish it.
The design of mixed signal circuit PCB is very complex. The layout and wiring of components and the processing of power supply and ground wire will directly affect the circuit performance and EMC performance. The partition design of ground and power supply introduced in this paper can optimize the performance of mixed signal circuit.
What types of RF PCB are available? The simple explanation of PCB production is to make samples according to the requirements. Ipcb, let's take a look at what types of PCB production are available.
