Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a corrosion-resistant circuit board packaging structure. Background Art

[0002] The names of circuit boards include: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, printed circuit board, aluminum substrate, high-frequency board, thick copper board, impedance board, printed circuit board, ultra-thin circuit board, ultra-thin circuit board, printed circuit board, etc.

After the upper protective plate and the lower protective plate are connected, a sealing ring is inserted into the inner cavity of the folded edge portion, and the outer wall of the sealing ring is tightly fitted with the inner wall of the folded edge portion, thereby forming a sealed chamber through the upper protective plate and the lower protective plate to prevent external air and corrosive substances from entering the interior. At the same time, inert gas is injected into the inner cavity of the upper protective plate and the lower protective plate, and the air remaining in the inner cavity of the upper protective plate and the lower protective plate is discharged by the inert gas, thereby forming a chamber filled with inert gas, further reducing the oxidation and corrosion rate of metal parts, and achieving the effect of anti-oxidation and anti-corrosion of circuit boards.

When the circuit board packaging structure is used, it is first necessary to insert the sealing ring into the inner cavity of the folded edge part, and fit the sealing ring tightly with the inner wall of the folded edge part. Then, the upper protective plate and the lower protective plate are fixed by using fasteners and connecting tubes, so as to package and protect the circuit board.
