Description

TECHNICAL FIELD

[0001] The utility model relates to a copper block buried PCB processing field, especially to a copper block buried PCB copper block brown bearing fixture. BACKGROUND

[0002] Compared with traditional PCB design, copper block buried PCB has better heat dissipation performance and electrical connection performance, can effectively provide a heat dissipation path in high-density integrated circuit and power device applications, reduces temperature and thus improves performance and reliability. With the continuous expansion of the electronic market and technological progress, copper block buried PCB is widely used in communication, automotive electronics, industrial control, medical equipment, aerospace and other fields, and its technology will develop towards diversification trends such as shape position diversification, size and thickness variety, and connection mode individualization.

[0003] In the processing of pressing the copper block and the PCB, in order to improve the bonding force of the copper block and the resin, the surface of the copper block is usually subjected to brown treatment.

[0004] However, due to the fact that the ultra-small size copper blocks are stacked together by the chemical solution during the brown treatment, the brown treatment is poor, and the copper blocks are scratched, which leads to poor bonding force and PCB board explosion, and thus reduces the quality of the PCB.

[0005] In order to avoid the above problems, it is necessary to provide a copper block buried PCB copper block brown treatment auxiliary jig to overcome the defects in the prior art. SUMMARY

[0006] The utility model discloses a copper block buried PCB copper block brown treatment auxiliary jig, solve the ultra-small size copper block brown treatment and be stacked together by chemical solution, lead to brown treatment is poor, and the copper block is scratched and the like problem.

[0007] The utility model discloses an embodiment is realized, a copper block buried PCB copper block brown treatment auxiliary jig, including board frame, its characterized in that, the board frame includes whole face paving net cloth and fixed position has one -way 90 degree bending movable page, be equipped with a plurality of net bags on the paving net cloth, the net bag can open with the one -way 90 degree bending of board frame, and the copper block is placed in the net bag after the brown copper block flat straight board frame.

[0008] Further technical solutions, the structure of the copper block buried PCB copper block includes different size thickness and shape.

[0009] Further technical solutions, the copper block thickness is 0.1-4.0mm.

[0010] Further technical solutions, the minimum size length of the copper block is 1mm, and the minimum size width is 1mm.

[0011] Further technical solutions, the mesh number of the paving net cloth is 30-140.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] The utility model not only can solve the problem that the ultra-small size copper block is pressed and overlapped together by the chemical water during the brown oxidation, causes the brown oxidation to be bad, and the problem of scratch, can be applied to different shape copper block, and can be repeatedly used, saves the cost investment, improves the production efficiency and improves the yield.
