SMT patch proofing processing and installation IC matters needing attention
SMT patch proofing processing and installation IC notes: 1, the welding time is short, not more than 3s, 2, the use of electric iron constant temperature 230 degrees, 3, proofing table do anti-static treatment. 4, choose some pointed and narrow iron head,
Can SMT surface mount technology speed up PCBA processing?
SMT surface mount technology has the following 5 steps: 1. PCB production - this is the actual production stage of PCB with solder points; 2. Deposit solder on the pad to fix the assembly to the plate; 3. With the help of the machine, the components are p
The difference and connection of solder paste, solder paste and solder paste in SMT patch processing
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
The role of AOI in SMT patch processing
What aspects of PCB have an impact on PCBA: one, PCB board surface dirty, two, white slag, three, PCB deformation
Method of preventing short circuit in SMT patch processing
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
What does SMT mean?
Literally, it is a technique for welding electronic parts to the surface of a PCB, unlike earlier through-hole parts, using "wave welding", which drastically reduces the size of electronic products to make them lighter, thinner, shorter and smal...
How to improve the straight through rate of SMT patch processing?
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;
Solder flux requirements for SMT patch processing
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
Detailed understanding of SMT patch processing and production process
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.
What is the function of AOI and SPI in SMT processing?
PCBA proofing processing common production procedures :1. Repair: 2. Mounting: 3. Testing: 4. Curing: 5. Cleaning: 6. Solder paste printing: 7. Reflow welding: 8. dispensing
SMT patch incoming material processing process
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
