The quality of solder joints is the most important part of PCBA processing. The reliability of solder joint quality determines the reliability and service life of PCBA products. Once the solder joint fails, the PCBA will be repaired or scrapped. Improving the reliability of solder joints is one of the processing goals of electronic processing plants. So, what is the reason for the failure of PCBA multilayer circuit board solder joints, I will introduce to you today.

In the process of PCBA foundry processing, tin penetration is very important. If the tin penetration of the PCBA board is not done well, it will face the risk of false soldering, tin cracking or even dropout. Today, let's learn about the factors that affect the penetration of PCBA manufacturing foundry materials!

When a pcba manufacturer board is soldered, there will be pores, which are commonly called bubbles. Porosity usually occurs during reflow soldering and wave soldering. A large number of pores cause damage to the PCB board. Here are several methods to prevent pores from PCBA processing and soldering.

Characteristic impedance refers to the resistance of the high-frequency signal or electromagnetic wave in the propagation process of the transmission signal line relative to a certain reference layer at a certain frequency, which is also called characteristic impedance. It is equivalent to a vector sum of electrical impedance, inductive reactance, and capacitive reactance.

Due to the precision and rigor of china PCB, the environmental sanitation requirements of every PCB workshop are very high, and some workshops are even exposed to the "yellow light" all day long. Humidity is also one of the indicators that need to be strictly controlled. Today we will talk about the impact of humidity on PCBA.
