Abstract
Description
Technical Field
[0001] The utility model relates to the field of printed circuit boards, in particular to a back drilling D+0 operation device. Background Art
[0002] A printed circuit board, also known as a printed circuit board, is a substrate used to connect and support electronic components. It is an important component of electronic equipment and is used to achieve circuit connection and wiring.
[0003] A printed circuit board is usually composed of one or more layers of insulating substrate covered with metal foil. Through processes such as etching or printing, the circuit pattern is transferred to the metal foil to form conductive circuits. These circuits connect the pins of electronic components, enabling the transmission and interaction of electrical signals between them.
[0004] The main function of the printed circuit board is to provide physical support and electrical connection for electronic components, while reducing circuit complexity and wiring errors. It makes the manufacturing of electronic equipment more standardized and reliable, and improves the maintainability and scalability of the circuit.
[0005] Signal transmission between layers is achieved through metallized through-holes on multi-layer printed circuit boards. For signal conduction between specified layers, the hole wall metal is often removed through a back-drilling process to specifically cut off the layers that do not need to be connected or transmitted. This process uses a drill bit larger than the through-hole diameter to perform controlled-depth drilling at the original through-hole position to remove the hole wall metal connecting non-specified layers, so that the remaining hole wall metal can achieve circuit conduction between local layers, thereby avoiding reflection, scattering and delay of high-speed signal transmission, causing signal "distortion".
