In the entire production process of the electronics industry in the past, the traditional soldering process often had disadvantages such as large residual amount, strong corrosiveness and poor appearance. After welding, it needs to be cleaned with plate cleaning water. During the cleaning process, due to the assembly of fine gaps and high-density components, it will cause cleaning difficulties, that is, increase the cleaning cost and waste working hours. Therefore, in order to meet the needs of the development of the electronics industry, a new type of no-clean solder has emerged nowadays. However, there are still many people who do not know what "no-clean" means? Now, the solder paste manufacturer will explain to you whether the solder wire does not need to be cleaned.
The so-called "no-cleaning" is usually used in the electronic assembly process with a low solid content and non-corrosive flux. The soldering process is carried out in an inert gas environment. After soldering, the residue on the circuit board is extremely small, non-corrosive, and has a high surface insulation resistance. Generally speaking, it can meet the standard requirements of ion cleanliness without cleaning. It can immediately proceed to the technological process of the next procedure.
The no-clean flux itself is an environmentally friendly flux that is limited to halide active agents and does not require further treatment after welding processing. The use of this type of flux not only saves the input cost of cleaning equipment and cleaning solvents, but also reduces the pollution caused by the emission standards of waste gas and waste water to the environment. If the no-cleaning flux is used to replace the traditional flux, there will be certain economic benefits and economic benefit analysis.
In fact, when choosing what kind of solder wire, the first thing to do is to observe its soldering quality. The surface of the solder wire should be clean and shiny, and there should be no many necessary foreign substances. Another point to consider is that the flux in the no-clean solder wire must be complete and there should be no slight gap; otherwise, it is very likely to cause false soldering, which will directly affect performance and quality.Lead-free solder wire without cleaningAll the packaging boxes need to be clearly marked with their specifications, net weight, product name and manufacturer. When everyone demands a product quality certificate, they can all ask them to provide an inspection report. The flux component in the no-clean solder wire is used to enhance the heat conduction of the solder wire and remove oxidation. The most prominent feature of this product is that it does not require cleaning after soldering processing, which can save a lot of manpower in many electronics industries. Therefore, its application in manufacturers is becoming increasingly widespread.
