In the production process of PCBA, various soldering techniques are often used to ensure stability, which can easily lead to residues on the surface layer. To guarantee the performance of the applied products, thorough cleaning is necessary before leaving the factory. What kind of cleaning support can the application of PCBA cleaning machines provide nowadays?…
Initially, in the early stages of PCBA assembly, fixtures were rarely used. Almost all PCBs could pass through the oven directly without the need for any fixtures unless the boards couldn’t withstand heavy loads, such as power boards. The use of fixtures for reflow soldering became prevalent with the rise of selective wave soldering, coupled…
The cleanliness of assembly components has become a significant concern in assembly operations. While the residues after assembly may not seem critical after the application of cleaning agents, they can cause failure in electrochemical analysis if the cleaning process is omitted. For instance, like the growth of branches, issues such as electrolytic corrosion and leakage…
There are several reliable methods for cleaning solder on circuit boards, depending on whether you need to clean existing solder on the board or remove unwanted solder residues after soldering. It is recommended to use the Silman Tech PCBA cleaning machine for these operations. Here are the methods: Manual Cleaning Equipment Cleaning Whether cleaning existing…
There are many options available for cleaning equipment nowadays, and they provide various practical values when applied. Among them, the application of fully automatic PCBA board cleaning machines is quite common, meeting the needs of various industries. So, what are the benefits of using them? Are they highly stable in operation? With the increasing demand…
After processing, there are often residues on the surface of PCBA, such as flux, solder paste, and solder dross, which can adversely affect product stability. Therefore, it is necessary to use a PCBA water cleaning machine for specific cleaning. So, what is the working principle of this type of machine? The PCBA water cleaning machine…
In the PCB production process, cleaning PCBA circuit boards is a crucial step. Failure to effectively ensure the cleanliness of the PCB surface can lead to resistance and leakage, causing PCB circuit boards to malfunction and significantly affecting their lifespan. So, how do we clean PCB circuit boards? Let me share with you several methods:…
These are the important considerations for using a steel mesh cleaning machine.
PCBA circuit boards undergo soldering processes such as reflow soldering, DIP wave soldering, and selective wave soldering in SMT electronic manufacturing processes. After soldering, PCB circuit boards and components inevitably have residues such as flux and solder paste. Excessive residues of solder paste, flux, and other substances on PCBA circuit boards can pose significant hazards.…
Before discussing why water-based cleaning agents are preferred over solvent-based ones for circuit board cleaning, let’s first examine the advantages and disadvantages of solvent-based cleaning agents. Organic solvent cleaning agents can be classified into flammable and non-flammable categories based on safety factors. Flammable solvents mainly include organic hydrocarbons, alcohols, and esters, while non-flammable solvents mainly…
