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…

In order to ensure the quality of products and the reliability and stability of technical parameters in SMT process production, standardized and reputable manufacturers conduct a major cleaning of the reflow oven every month. This includes disassembling and cleaning removable parts such as condensers, fans, and filters. Resin residues and solid adhesive substances may adhere…

The printer is the front-end process equipment of the SMT production line, mainly used to print solder paste onto PCB pads. An important component required for printing onto the pads is the stencil. The stencil, essentially a template matching the PCB pads, contains holes corresponding to the PCB pads and is primarily used by the…

After using reflow soldering for a period of time, a large amount of rosin flux residue from the solder paste remains on the inner walls of the reflow soldering oven chamber and the cooling zone pipes. This can reduce the heating temperature of the reflow soldering, leading to poor soldering quality. Therefore, it is necessary…

The steel mesh cleaning machine is a specialized equipment used for cleaning steel meshes. It thoroughly cleans dirt, grease, and other impurities from the steel mesh using high-pressure water flow and nozzles. This type of cleaning machine is commonly used in industrial production lines, such as automotive manufacturing and electronics production fields. Using a steel…
