In surface mount technology (SMT) printed circuit boards (PCBs), welding paste printing is crucial. Since welding paste directly determines the formation of welding joints, its printing quality has a decisive influence on the performance and
The production process of SMT processing is extremely complex, and each process is closely linked. Problems in any link will affect product quality. To enhance the quality of PCBA processing and soldering, professional testing equipment
In the wave welding machine, the larger the contact area between the molten welding and the air, the more tin oxide is generated. The size of the contact area is directly related to the opening
BOM table The Bill of Materials, or BOM (Bill of Material), is a document that describes the product structure in detail in the form of data. In the SMT processing process, BOM includes key information
The core processes of SMT processing include solder paste printing, SMT machine operation, and reflow soldering. Only by effectively controlling the SMT process flow can we ensure the excellence of processing quality and improve
1.Purpose: The operator can use the VS-600 pneumatic packaging machine correctly to avoid improper operation that may affect product quality, cause machine failure, or cause personal injury. 2.Scope: All humidity-sensitive components (PCB, IC, BGA, QFP)
With the rapid development of electronic information technology, I believe many people have heard of the two professional terms "PCB" and "PCBA" and are not unfamiliar with them. After an in-depth discussion, we found that
15 basic components of PCB If you do not know about electronic circuit board, you should be aware of PCB. But why do you need to know this, you may ask? These circuit boards are
PIP technology is a method of assembling through-hole components using a standard reflow welding process. This process is also called THTR (Through-hole Technology Reflow). In most printed circuit boards (PCBs) containing surface mount components
During the welding process, the PCB pad often falls off due to long welding time or multiple weldings leading to high temperature, which causes the pad copper sheet to expand repeatedly and fall off.
