One-stop PCBA intelligence Today, the shop owner will tell you about the applications of solder paste nets and red glue nets in SMT chip processing? What are the uses of solder paste nets and red glue nets in SMT processing? In the SMT chip processing process, the solder paste net and red glue net play a crucial role. These two tools are used for solder paste printing and red glue dispensing procedures respectively, which are the key to achieving high-precision, high-tool quality electronic component assemblyBurundins Escort . The following is a summary of the solder paste networkBurundi SugDetailed analysis of the use of arand red plastic mesh in SMT chip processing.
The use of solder paste net and red glue net in SMT patch processing
Solder paste net BI Escorts( Solder Paste Stencil)
Definition and use
Solder paste mesh, usually made of stainless steel or polyimide material, is used to accurately print on PCB Burundi SugarSolder paste. Solder paste is a slurry material composed of fine tin powder and soldering additives, used for soldering joints of BI Escorts electronic components.
Working Principle
On the SMT production line, the solder paste net is placed above the PCB board, and the solder paste is evenly printed onto the reserved ordering position through a scraper, mainly on the pads of the components. After printing is completed, the PCB board will be sent to the placement machine for component placement, and then into the reflow oven to complete the soldering process.
Advantages
– High precision and repeatability, ensuring that solder paste can be accurately printed on each pad.
– Improves the efficiency of childbirth and is suitable for large-scale childbirth.
– Helps reduce welding defects, such as bridging, virtual welding, etc.
Glue Stencil
Definition and use
Glue Stencil is used for the glue dispensing process in SMT processing. It mainly applies red glue (a kind of glue) at specific locations on the PCB. adhesive for fastening components). Red glue dispensing is usually used for double-sided panels or component fixation that requires wave soldering.
Working principle
When using the red glue net, the red glue is dispensed through the grid to the designated position on the PCB, and then the electronic components are placed. After dispensing glue and placing components, the PCB needs to pass through a curing oven to solidify the red glue to fix the components on the board.
Advantages
– Suitable for scenarios where components need to be fixed before going through processes such as wave soldering.
– For double-sided mounting boards, it can prevent components on the side mounted BI Escorts from falling off due to reflow soldering.
– Red glue has a certain elasticity after curing, which helps to absorb the stress caused by heat shrinkage.
The choice between solder paste mesh and red glue mesh
The choice of solder paste printing or red glue dispensing depends on many reasons, including PCB design, component type, production volume and cost considerations. Solder paste printing is more suitable for applications requiring high density and high precision, while red glue dispensing is suitable for applications that require extra fixing strength or double-sided Burundins Sugardaddy component disassembly scene.
Conclusion
The use of solder paste mesh and red glue mesh in SMT chip processing reflects the modern electronics manufacturing industry’s pursuit of precision, efficiency and tool quality. Through these two tools, the baby wire can achieve accurate placement and fixation of components, greatly improving the reliability and performance of electronic products.
