ABB PM153 PCB Board 3BSE003644R1 PM153 Controller module

PCB have the following functions in electronic equipment.
(1) Provide mechanical support for fixing and assembling various electronic components such as integrated circuits, realize wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits, and provide the required electrical characteristics.
(2) Provide solder resistance graphics for automatic welding, identification characters and graphics for component insertion, inspection and maintenance.
(3) Electronic equipment using printed board, because of the consistency of similar printed board, avoid manual wiring errors, and can realize the automatic insertion or installation of electronic components, automatic soldering, automatic detection, to ensure the quality of electronic products, improve labor productivity, reduce costs, and easy maintenance.
(4) Provide the electrical characteristics, characteristic impedance and EMC characteristics required for the circuit in high speed or high frequency circuits.
