Abstract

The invention relates to a horizontal-line multi-washing serial washing overflow structure which comprises a first washing area and a second washing area, wherein the first washing area comprises a first-level washing pool, a second-level washing pool and a third-level washing pool; the second washing area comprises a fourth-level washing pool, a fifth-level washing pool and a sixth-level washing pool; the first-level washing pool and the second-level washing pool are communicated by an overflow outlet; the second-level washing pool and the third-level washing pool are communicated by an overflow outlet; the fourth-level washing pool and the fifth-level washing pool are communicated by an overflow outlet; the fifth-level washing pool and the sixth-level washing pool are communicated by an overflow outlet; and the sixth-level washing pool is provided with an overflow inlet. The invention is characterized in that first bypass lines are connected in parallel between the fourth-level washing pool and the third-level washing pool, and the first-level washing pool is connected with a sprinkling pipe by second bypass lines. The horizontal-line multi-washing serial washing overflow structure has low renovation cost, realizes reasonable water resource utilization, and requires little change to original structure of equipment.

Description

Technical field [0001] The invention relates to a water-washing overflow structure for multiple water washing in series in a horizontal line, in particular to a water-washing overflow port used for a horizontal line of a wet process in the printed circuit board industry. Background technique [0002] In the precision circuit printed circuit board industry, the requirements for the cleaning effect of the circuit board are relatively strict, and the common horizontal lines are often washed with multi-stage countercurrent overflow water, such as figure 1 As shown, the inner layer of the DES (Development-Etch-Remove) line has two independent 3-stage countercurrent washings after the film is removed. The conveying direction is from right to left, and the water flow direction is from left to right. Each grid in the figure represents inspection. Section 18, the first-stage washing tank 11, the second-stage washing tank 12, the third-stage washing tank 13, the anti-oxidation zone 17, the...
