What is the reason for the displacement of components in SMT chip processing? The main purpose of MT chip processing is to accurately install the surface mount components on the fixed position of the PCB.THT&SMT equipment， Sometimes there will be some process problems during the chip processing process, such as various process problems such as component displacement.
Regardless of the country of origin, this should be taken seriously. The reasons for no equipment shifting can be found from the following aspects:
Reasons for component displacement in SMD machining:
1. The flux content in the solder paste is too high, and the flux flows too much during the reflow process, causing the components to shift.
2. During patch processing, the air pressure of the suction nozzle is improperly adjusted, and the pressure is not enough, causing the components to shift.
3. The mechanical problems of the placement machine itself lead to component placement errors. Once the components are displaced in the smt chip processing, it will affect the performance of the circuit board
