Abstract
The invention discloses an acid tank-washing agent for a developing stripping tank. The acid tank-washing agent comprises the following raw materials in percentage by mass: 20 to 35 percent of hydrochloric acid, 10 to 20 percent of trisodium phosphate, 2 to 7 percent of propylene glycol monomethyl acetate (PMA) and 5 to 15 percent of citric acid. The tank-washing agent has a good washing effect and can effectively remove attachments attached to tank walls, pipes and nozzles.
Description
Technical field
The present invention relates to a kind of development striping groove with acid washing trough agent.
Background technology
The internal layer of PCB is made flow process and is comprised steps such as cutting out plate, pre-treatment, coating, exposure, development, etching, striping, and in the prior art, yellow soda ash, salt of wormwood are widely used in the green lacquer development of dry film striping process; Owing to contain a large amount of carbanions in the tank liquor, when itself and calcium ions and magnesium ions in the water combine, just can generate deposition; Along with the equipment prolongation of duration of service, during untimely again clear groove, a large amount of depositions is attached to the place of easy foulings such as cell wall; Be blocked in pipeline and the nozzle; The life-span that influences the equipment works better even reduce equipment, however the cleaning performance of existing washing trough agent is unsatisfactory.
Summary of the invention
The purpose of this invention is to provide a kind of development striping groove with acid washing trough agent.
The technical scheme that the present invention taked is:
A kind of development striping groove is with acid washing trough agent, and it comprises the hydrochloric acid of the raw material of following mass percent: 20-35%, the tsp of 10-20%, the PMA of 2-7%, the Hydrocerol A of 5-15%.
It comprises the hydrochloric acid of the raw material of following mass percent: 25-32%, the tsp of 12-18%, the PMA of 3-6%, the Hydrocerol A of 8-12%.
Described tsp is anhydrous level tsp.
The concentration of said hydrochloric acid is 37%.
The invention has the beneficial effects as follows: washing trough agent cleaning performance provided by the present invention is good, can effectively remove attached on the cell wall, the dirt settling located such as pipeline and nozzle.
Description of drawings
Fig. 1 is the pictorial diagram without the roller in the major trough that cleans.
Fig. 2 is to use washing trough agent of the present invention to clean the pictorial diagram of rear roller.
Fig. 3 is without the filter screen pictorial diagram of cleaning.
Fig. 4 is the filter screen pictorial diagram after cleaning through washing trough agent of the present invention.
Embodiment
