Solder paste, solder paste, and solder paste are two kinds of products - solder paste and solder paste, solder paste and solder paste can be distinguished from the appearance of color, solder paste is yellow, solder paste will hair gray or black, this is
What aspects of PCB have an impact on PCBA: one, PCB board surface dirty, two, white slag, three, PCB deformation
Design methods to reduce stray capacitance of PCB: 1, remove the inner stratum, 2, use the Faraday shield, 3, increase the space between adjacent trace lines, 4, minimize the use of holes
To improve the pass rate of SMT patch processing, the following five process optimization methods are required :1. Improved pcb circuit board steel mesh design;2. Select the appropriate solder paste type; 3. Improve the printing process operation method;
SMT patch processing for the requirements of flux: 1. The appearance of the flux should be uniform, transparent, no foreign matter. 2 viscosity and density than molten solder is small, 4 melting point than solder is low, 5 welding does not produce welding
SMT patch processing refers to the process of pasting electronic components and other materials on PCB bare board. It is a popular processing technology in electronic assembly industry.
Why should we do electrostatic protection in PCBA processing? PCBA board has precision electronic components, many components are more sensitive to voltage. A shock above the rated voltage will damage these components
SMT patch processing common detection methods: 1, optical detection method, 2, artificial visual detection method, 3, AOI detection method
SMT patch processing common materials: 1, patch resistance, 2, patch capacitor, 3, induction coil, 4, transformer, 5, crystal diode, 6, field effect transistor
SMT processing plant plays an important role in the electronic processing industry, which is indispensable for the precision and miniaturization of electronic products
SMT patch processing main characteristics: 1, high density: 2, small aperture: 3, low coefficient of thermal expansion: 4, high temperature resistance performance:
Manual welding methods for SMT patch processing of leadless chip components: one by one welding spot, two, using special tools horseshoe iron head welding, three, using flat chip iron head quick welding
