[0002] Embedded copper block PCB is a technology that embeds metal copper blocks in the local position of the PCB board corresponding to the high-power components. When used by the client, the high-power components are directly mounted on the metal block. The large amount of heat generated by the components during operation is conducted to the dedicated heat dissipation device on the other side of the PCB through the metal block, thereby effectively reducing the operating temperature of the components and PCB and increasing the service life of the equipment. In order to improve the bonding strength of the metal copper block embedded in the PCB board, the metal copper block will be browned to roughen the surface.

[0003] At present, the copper block is browned using a browning jig. The copper block is placed in the jig and passes through a horizontal browning line to achieve the purpose of browning. The existing jig design allows the copper block to easily slide to the side wall of the jig and fit together during the browning operation after the copper block is placed in. When this happens, the side wall of the copper block will be poorly browned, and the potion at the fitting will not dry, which will cause quality problems and reduce the quality of the copper block browning.

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] First embodiment

[0025] Please refer to Figure 1 , Figure 2 ,in, Figure 1 A schematic structural diagram of a first embodiment of a jig for browning a buried copper block provided by the utility model; Figure 2 for Figure 1 A magnified schematic diagram of part A is shown. A jig used for browning of buried copper blocks comprises: a substrate 1, a top of the substrate 1 is provided with a plurality of rhombus-shaped grooves 11, and the bottoms of the inner sides of the plurality of rhombus-shaped grooves 11 are provided with first through holes 12;

[0026] The copper block 2 is arranged on the inner side of the diamond-shaped groove 11.

[0027] A plurality of first through holes 12 are provided and are evenly distributed at the bottom of the inner sides of the plurality of diamond-shaped grooves 11 .

[0028] The working principle of a fixture for browning copper blocks provided by the utility model is as follows:

[0029] When the substrate 1 is grooved, the groove on the top of the substrate 1 is grooved into a diamond-shaped groove 11 instead of a rectangle, and then the copper block 2 is placed into the inner side of the diamond-shaped groove 11 so that the four corners of the copper block 2 are stuck on the inner side of the diamond-shaped groove 11, thereby limiting the position of the copper block 2 and preventing the length and width of the side walls of the copper block 2 from touching the groove wall.

[0030] Compared with the related art, the jig provided by the utility model for browning copper blocks in buried copper blocks has the following beneficial effects:

[0031] A diamond groove 11 is formed on the top of the substrate 1, and the copper block 2 is placed into the inner side of the diamond groove 11, so that the four corners of the copper block 2 are stuck in the inner side of the diamond groove 11. In this way, the copper block 2 can be limited, thereby preventing the copper block 2 from sliding during the browning process and causing the side wall of the copper block 2 to touch the side wall of the fixture, thereby increasing the quality of the browning of the copper block 2.

[0032] Second embodiment

[0036] The cover plate 3 is provided with side grooves 34 on all sides thereof, and a through groove 33 is also provided on the top of the inner side surface of the cover plate 3 .

[0037] When the bottom of the cover plate 3 is against the top of the limiting plate 35, the bottom of the retaining ring 31 will be at the top of the copper block 2 and will not contact the top of the copper block 2. In this way, the copper block 2 can be limited and direct pressure on the top of the copper block 2 can be avoided, thereby affecting the browning effect.

[0038] The working principle of a fixture for browning copper blocks provided by the utility model is as follows:

[0039] After placing the copper block 2 into the inner side of the diamond groove 11, the user can then cover the cover plate 3 on the top of the outer side of the substrate 1, and press the bottom of the cover plate 3 on the top of the limiting plate 35. At this time, the bottom of the retaining ring 31 will be at the top of the copper block 2, thereby limiting the copper block 2 on the inner side of the diamond groove 11. When browning and cleaning is performed later, the liquid can enter the inner side of the cover plate 3 through the second through hole 32, the through groove 33 and the side groove 34 to brown the copper block 2.

[0040] Compared with the related art, the jig provided by the utility model for browning copper blocks in buried copper blocks has the following beneficial effects:
