Abstract
According to one or more embodiments described herein, an electronic power steering system includes a motor, and a semi-flexible ridged printed circuit board (PCB) assembly that is coupled with the motor. The semi-flexible ridged PCB assembly includes a first portion, a second portion, and a bendable member that couples the first portion and the second portion. The first portion is bendable with respect to the second portion using the bendable member.
Claims17
An electronic power steering system comprising:
- a motor;
- and
- a semi-flexible ridged printed circuit board (PCB) assembly that is coupled with the motor, the semi-flexible ridged PCB assembly comprises:
- a first portion of rigid PCB material;
- a second portion of rigid PCB material;
- a bendable member of rigid PCB material with at least one milled portion, the at least one milled portion having a thickness less than a thickness of the first portion and the second portion, the bendable member couples the first portion and the second portion and spaces the first portion from the second portion, the first portion being bendable with respect to the second portion using the at least one milled portion of the bendable member;
- wherein the bendable member is formed at least partially of copper material and the bendable member is pre-impregnated;
- and
- wherein the milled portion is formed in the copper material by depth controlled milling of the bendable member that is pre-impregnated.
A semi-flexible ridged printed circuit board comprising:
- a first portion of rigid PCB material;
- a second portion of rigid PCB material;
- a bendable member of rigid PCB material with at least one milled portion the at least one milled portion having a thickness less than a thickness of the first portion and the second portion, the bendable member couples the first portion and the second portion and spaces the first portion from the second portion, the first portion being bendable with respect to the second portion using the at least one milled portion of the bendable member;
- wherein the bendable member is formed at least partially of copper material and the bendable member is pre-impregnated;
- and
- wherein the milled portion is formed in the copper material by depth controlled milling of the bendable member that is pre-impregnated.
A system comprising:
- a motor;
- and
- a motor control system comprising a semi-flexible ridged printed circuit board comprising one or more electronic circuits to control operation of the motor, the semi-flexible ridged printed circuit board comprising:
- a first portion of rigid PCB material comprising connector circuits for coupling the semi-flexible ridged printed circuit board with the motor;
- a second portion of rigid PCB material comprising one or more controllers for operating the motor;
- a bendable member of rigid PCB material with at least one milled portion the at least one milled portion having a thickness less than a thickness of the first portion and the second portion, the bendable member couples the first portion and the second portion and spaces the first portion from the second portion, the first portion being bendable with respect to the second portion using the at least one milled portion of the bendable member;
- wherein the bendable member is formed at least partially of copper material and the bendable member is pre-impregnated;
- and
- wherein the milled portion is formed in the copper material by depth controlled milling of the bendable member that is pre-impregnated.
