In the process of PCBA processing, the solderability of PCBA directly affects the quality of the product. Some small inadvertent errors will directly PCBA solderability, it is very important to understand the decisive factors affecting PCBA solderability.
PCBA solderability is actually PCBA soldering effect, mainly determined by the following four factors.
I. The characteristics of the solder paste
Solder paste factors play a very important role in the solderability of PCBA, different components of the paste, storage conditions do not meet the standard and other factors will affect the solderability of PCBA.
II. The quality of the PCB substrate
PCB board production process will also affect the solderability of PCBA, often easy to bring very big quality problems, if the PCB board is bad, will lead to all the PCBA soldering bad, which is very serious.
III. The components
Components as the soldered parts, components in the oxidation of moisture, in the welding is easy to produce short circuit, cracks and other bad.
IV. The environment
In SMT workshop, the control of the environment is very important, the temperature and humidity are required, the temperature is too high and too low will have an important impact on the solderability of PCBA.
The impact of the PCBA solderability is actually very complex, solder paste, PCB board, components and the environment of these four factors are the decisive factors affecting the PCBA solderability, in the production process, through the control of these four factors can effectively improve the quality of the product.
