The embodiment of the present application provides a preparation method of a copper block browning jig and a copper block browning jig. The method includes: providing a tray, a cover plate, a first screen and a second screen; and the preset area of the cover plate are respectively milled to form tray slots and cover plate slots respectively; the inner wall of the tray slot and the inner wall of the cover plate slot are milled to form a plurality of symmetrically distributed Groove; fix the first screen at the position corresponding to the slot of the tray at the bottom of the tray, fix the second screen at the corresponding opening of the cover at the top of the cover At the position of the groove; the tray and the cover plate are fixed from bottom to top, and the tray, the cover plate, and the cavity form a browning fixture for the copper block to be browned. The method provided in this embodiment can overcome the cumbersome operation in the prior art, and problems such as scratches and pollution on the copper block are likely to be caused during the operation.
Description
technical field [0001] The embodiments of the present application relate to the technical field of browning of copper blocks, in particular to a method for preparing a jig for browning of copper blocks and the jig for browning of copper blocks. Background technique [0002] Embedding a metal copper block with good thermal conductivity in a PCB (Printed Circuit Board, printed circuit board) is a high-performance heat dissipation method. Before the embedding copper block PCB board is pressed, the copper block to be embedded needs to be browned to clean and roughen the surface of the copper block and improve the bonding force of the copper block. [0003] At present, the size of the copper block used in PCB is small, generally in the cm (centimeter) level, and the distance between the rollers of the horizontal browning line exceeds the size of the copper block, so the copper block cannot pass through the horizontal browning line. If the browning is carried out directly, it is ...
