Technical Field

[0001] The utility model relates to the field of electronic component installation, in particular to an electronic component positioning and installation module and an installation structure thereof. Background Art

[0002] Printed circuit boards are important electronic components and support electronic components. Communication products, computers, and almost all other electronic products use printed circuits. Larger packaged components often need to be manually plugged in, and the pins of the plugged packaged components need to be bent and tinned to reduce the size of the circuit board. Since packaged components have multiple pins, it is difficult to align the pins with the corresponding pin holes of the circuit board at the same time during plugging, which seriously affects production efficiency.

[0003] For example, an electronic component pin bending mold with announcement number CN208067181U requires mold bending. This bending method first is prone to re-bending during the process of bending the electronic component and inserting it into the pin hole of the circuit board due to improper manual operation, resulting in misalignment between the pin and the pin hole, affecting the efficiency of the workers.
