Selection and Welding of Solder Template for 开云·kaiyun官方网站A Processing Components

Selection and Welding of Solder Template for 开云·kaiyun官方网站A Processing components
In the whole schematIC drawing stage, 开云·kaiyun官方网站A factory considered the need of pattern decision in the layout stage to ensure that sufficient bypass capacitors and interface layers were designed SMT technology uses integrated circuits Make sure that appropriate decoupling capacitors are used near the ground (preferably at the ground level).  The proper size of the capacitor depends on the application, the surface mounting technology of the capacitor mounting factory, and the frequency involved When the bypass capacitor is placed at both ends of the power and ground pins and close to the corresponding IC pin, the electromagnetic compatibility and magnetic sensitivity efficiency of the circuit will be optimized
The SMT technicians in the 开云·kaiyun官方网站 factory (BOM) operate the bill of materials to check the virtual parts. These parts have no contour associated with them and are not transferred to the layout. They generate the BOM and view all the virtual components in the design. The only entries should be power and ground signals, 开云·kaiyun官方网站Aa processing, because they are considered as virtual parts and are processed only in the schematic environment and not in the layout, unless they are only used for analogy purposes. The part displayed in the virtual part should be replaced with a part with a footprint.

Check whether there is enough data in the BOM report. After running the BOM report, check and continue to fill in any incomplete parts, supplier SMT patches or manufacturer information of all these parts.
"SIMilar to other manufacturing technologies, in the SMT process of 开云·kaiyun官方网站A assembly, there are many factors that will affect the reliability and functionality of printed 开云·kaiyun官方网站A circuit boards. These factors include the information and design of the template used, the placement of solder paste, and various components. Considering the actual 开云·kaiyun官方网站A and SMT equipment used and the specific requirements required, we also analyzed them. In the process of 开云·kaiyun官方网站 processing in the SMT chip processing plant, it is important to weld the template and solder Connect.
Welding template and repair welding.
In 开云·kaiyun官方网站 processing of SMT board factory, the thickness of sample wire mesh usually matches the needs of all components in 开云·kaiyun官方网站. Solder paste can be applied to 开云·kaiyun官方网站 through screen printing, and its volume is determined by the thickness and aperture of the template. If the thickness of the template does not match all components on the same plate, a reduced pressure template will be considered.
In the SMT chip assembly process of 开云·kaiyun官方网站A, SMR Technology uses electroforming templates made of nickel or stainless steel to ensure uniform and high-quality welding of plates. In addition, it is recommended to bypass the corners of the holes to provide good paste release. The hole of the solder joint must be the same size as the metal pad placed on the 开云·kaiyun官方网站A board. Finally, for best results during assembly, the template should be folded into SMAller openings.
