High-frequency digital pickup circuit board based on deep hole electroplating technology

The utility model discloses a high-frequency digital pickup circuit board based on a deep hole electroplating technology. The high-frequency digital pickup circuit board comprises a protective layer, a pickup element, a circuit element, a deep hole pipe, a positioning hole, a butt joint hole and a circuit layer. According to the high-frequency digital pickup circuit board based on the deep hole electroplating technology, the electrolyte flows downwards along the inner wall of the extension laminate, and the anti-slip surface on the inner wall of the extension laminate prevents the electrolyte from flowing downwards quickly, so that more electrolyte is reserved on the surface of the extension laminate, a thicker electroplated layer is formed, and the service life of the circuit board is prolonged. When the interiors of the extension layer plate and the built-in through hole are too dirty, the protection layer and the circuit layer are separated from each other, then the pipe body and the external installation
