Etching device for positive concave etching of super-thick copper wire of ceramic-based circuit board

Abstract

The invention provides an etching device for positive concave etching of a super-thick copper wire of a ceramic-based circuit board, which relates to the technical field of circuit board processing and comprises an assembly line, a hanging part, an auxiliary part and a mixing part, the assembly line is fixed on the mounting frame through bolts; the hanging part is composed of a sliding block, a connecting base, a hanging rod, a baffle ring, an elastic piece and an auxiliary rod. The containing box is of a bottomless rectangular box-shaped structure, the blocking rods are welded to the bottom of the containing box in a linear array mode, and the circuit board needing to be etched is placed on the blocking rods; the blocking rod is of a cylindrical rod-shaped structure, so that the bottom end face of the circuit board can be ensured to be fully contacted with etching liquid after the containing box is placed in the etching box, thereby reducing etching dead angles, and solving the problems that a worker needs to bend down to manually place the circuit board in the etching box during etching at present, the worker is easy to fatigue, and the etching time is shortened. The efficiency is influenced; and after etching is completed, a worker needs to manually shake the circuit board to realize draining, and the operation is tedious.

Description

technical field [0001] The invention relates to the technical field of circuit board processing, in particular to an etching device for positive concave etching of ultra-thick copper wires of a ceramic base circuit board. Background technique [0002] Etching is a technology that removes materials by chemical reaction or physical impact; circuit boards are important carriers of electronic components. By installing electronic components on corresponding circuit boards, further operations can The connection between electronic components is convenient for the operator to centrally process and control the electronic components; with the continuous application of circuit boards, the production industry of circuit boards is also developing, and the etching of circuit boards is a necessary processing link in circuit board processing. , In particular, the ultra-thick copper wire of the circuit board requires positive concave etching. At present, the immersion etching method can achi...

Problems solved by technology

[0003] However, as far as the current etching device for the ultra-thick copper wire etching of the traditional base circuit board is concerned, first of all, the staff need to bend down and manually place the circuit board in the etching box during etching, so the reciprocation is easy to cause the staff fatigue , and affect the efficiency; secondly, after the etching is completed, the staff needs to shake the circuit board manually to drain the water, and the operation is cumbersome
