Eight common technical problems of PCB design
What samples should be provided for PCB circuit board proofing? The quotation information needs to be provided to the manufacturer, and the GEBER file is generally provided for the drawings. There are clear process requirements and quantity. The pcb manuf
There are three requirements for PCBA processing
PCBA processing needs to do three requirements: first, the solder paste, must be stored in 5-10 degrees of environment. In order not to affect the use of solder paste, shall not be placed in the environment below zero, second, in the process of SMT proces
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
