Impedance control means making sure the size and position of the lines on a circuit board match the material it's made from. This helps keep the power of the signal on the lines just right, so it works the way it should.
A Flexible Printed Circuit Board (Flex PCB), also known as a flexible circuit or flex circuit, is a type of printed circuit board (PCB) that offers flexibility in its design and shape, allowing it to bend or conform to various three-dimensional shapes.
PCB enclosures are integral components of electronic systems, providing protection, organization, and functionality. Here are steps and considerations to guide you in designing the appropriate PCB enclosure.
