When discussing the importance of the PCBA cleaning process, it involves various aspects such as cleaning methods, cleaning agents, and cleaning standards. User Zhang Min mentioned several instances where improper cleaning led to changes in device performance, such as reduced insulation performance of transformers and decreased contact performance of key switches. Recently, Zhang Min specifically…
PCB cleaning machines with surface dust and electrostatic discharge (ESD) removal systems have become increasingly popular. Many newcomers may wonder, “Isn’t a PCB board ready for use straight away?” However, during various stages such as handling, barcoding, and placement of PCBs, dust and stains may accumulate on the surface layer, and static electricity on the…
The pneumatic stencil cleaning machine offers clear advantages compared to ultrasonic stencil cleaning machines and manual cleaning methods for stencils. Regardless of whether it’s ultrasonic or manual cleaning, the ultimate challenge lies in how to clean stencils with small apertures and effectively avoid damaging the stencil. Below, we’ll primarily discuss what a pneumatic stencil cleaning…
As SMT technology advances, electronic components become increasingly miniaturized, and the future trend undoubtedly leans towards even smaller components. When mounting chips, frequent component rejection and equipment downtime due to nozzle blockages from solder and floating dust significantly impact production capacity. Here are several factors explaining why SMT electronics factories opt for Silman Tech’s automatic…
The two most widely used cleaning machines in the cleaning industry are high-pressure cleaning machines and ultrasonic cleaning machines. What are the differences between them, and how should users choose between them? Difference in working principles: The working principle of an ultrasonic cleaning machine involves converting electrical energy into mechanical energy through a transducer to…
The ultrasonic type cleaning machine utilizes ultrasonic waves to quickly dislodge contaminants from the nozzles. However, its cleaning effectiveness for nozzles varies and may not be optimal for all sizes of nozzle apertures. Ultrasonic cleaning is suitable for larger aperture nozzles but may risk damaging the nozzles, especially when combined with solvent cleaning. On the…
Manual cleaning: Use circuit board-specific cleaning solution to clean the dust from the circuit board. After cleaning, use a blow dryer to dry the circuit board. Since circuit boards typically contain electronic components, it is not suitable to use water for cleaning. Instead, use specialized board cleaning water, hydrogen peroxide, or deionized water for better…
As for cleaning wave soldering fixtures, the general recommendation is to use the Silman Tech fully automatic fixture cleaning machine DEZ-C756. This equipment is used for cleaning various workpieces, such as wave soldering fixtures, reflow soldering trays, and condensers, removing flux residues, oil stains, dust, etc., from the surface of machine parts. The workpieces undergo…
All three cleaning techniques mentioned above can achieve a certain level of cleaning effectiveness. However, to achieve rapid and efficient cleaning of PCB boards, the application of PCBA brush cleaning machines is recommended. These machines employ multiple brushing steps to efficiently remove flux residues from the surface of PCBA after soldering, without wetting the components.…
There are several types of wave soldering fixtures, and efficient cleaning methods for these fixtures are essential. With the rapid development of electronic devices towards miniaturization, lightweight, and precision, the standards for product quality are becoming increasingly higher. However, people often overlook the maintenance and cleaning of fixtures and equipment in common electronic processes, such…
