During the SMT assembly process, residues of solder paste and flux are often left behind on PCBA boards. These residues contain various components, including organic acids and decomposable ions. Organic acids are highly corrosive, and residual ions on solder pads can cause short circuits. Additionally, these residues make the PCBA boards dirty and fail to…
Choosing the appropriate cleaning agent for a stencil cleaning machine has always been a point of confusion for many. Today, I’ll explain six points to help you select a suitable cleaning agent for your stencil cleaning machine. With so many stencil cleaning agent products on the market, how do you make the right choice? Here…
Cleaning and maintaining Pick and Place Machine (SMT) nozzles are crucial tasks as they are essential components responsible for picking up and placing surface mount electronic components. If these nozzles malfunction or become blocked, the pick-and-place process cannot proceed as electronic components cannot be picked up. Therefore, regular cleaning and maintenance of SMT nozzles are…
PCB, which stands for Printed Circuit Board, is also known as a printed wiring board, serving as a provider of electrical connections for electronic components. It is present in various electronic products and serves as a carrier for the interconnection of electronic devices such as resistors, capacitors, inductors, diodes, transistors, integrated circuits, etc. PCB boards…

When it comes to PCBA processing technology flow, factors that cannot be overlooked include the assembly density of PCBA components and the equipment conditions of the SMT production line. PCBA, which stands for Printed Circuit Board Assembly, involves the entire process of SMT mounting followed by DIP insertion. The choice of the process flow mainly…
The above is the process of cleaning steel mesh with the DEZ-C730 steel mesh cleaning machine, which is simple to operate and one-touch cleaning. If there are any unclear points, you can consult the online customer service for detailed understanding of the operation of the steel mesh cleaning machine through instructional videos.
Firstly, timely cleaning is essential. For reflow oven fixtures, it is generally recommended to clean them once a week after use, and also clean them once when taken offline to prevent excessive flux residue on the edges of the reflow oven fixtures due to prolonged use, which can make cleaning difficult and affect fixture performance.…
The main function of SMT steel mesh is to accurately print solder paste onto PCB pads. During this process, some solder paste residue is inevitably left on the steel mesh, which needs to be cleaned after use to avoid affecting secondary use. In order to achieve good cleaning results and control costs, it is necessary…
Steel mesh cleaning, from manual cleaning to automated cleaning achieved through solvent-assisted pneumatic spraying, has become an efficient, environmentally friendly, and safe application direction and development in the industry. This application better meets the cleaning needs of manufacturers in this area and the requirements of environmental protection, sustainability, and scientific development of society, ensuring a…
