This paper summarizes the packaging problems prone to occur in SMT patch processing
Reflow welding may have some effects on SMT machining quality: 1. PCB deformation caused by temperature gradient; 2. Component damage caused by temperature gradient, 3. Oxidation in reflow welding process
Factors affecting SMT patch processing straight through rate
There are five technological means to improve the pass-through rate: (1) optimize the design of steel mesh, (2) select the appropriate solder paste, (3) optimize the printing operation, (4) optimize the temperature curve, (5) adopt tooling and improve the
A good SMT patch factory will do this!
In order to do a good job in PCBA processing, we need to do the following three things: first, solder paste should be used during SMT processing; second, the SMT equipment must be checked frequently during SMT processing; third, we should always pay atten
What are the factors affecting SMT machining quality?
Factors affecting SMT processing quality: 1, equipment, 2, technology, 3, PCB circuit board, 4, steel mesh (template), 5, furnace temperature curve setting
What is the minimum length of SMT patch proofing material braid?
Requirements on the minimum length of tape for SMT patch proofing materials: In the production process of SMT patch, materials are mainly packaged by pallets and tape braiding. Such packaging is convenient for taking materials from the SMT patch machine a
SMT patch processing how to achieve efficient refueling?
Polarity means that the positive and negative electrodes or first pins of a component are in the same direction as the positive and negative electrodes or first pins on the PCB(printed circuit board). If the component does not match the direction on the P
How can SMT factories improve the efficiency of SMT processing?
Ways to improve SMT machining efficiency: (1) Aim for fewer component changes, (2) Focus more on PCBA assembly, (3) You should know every step of the SMT process
