Problems solved by technology

[0004] However, because the dry film of COF products is very thin and the lines are dense and slender, once it comes into contact with other objects, it is easy to cause scratches on the dry film or damage to the lines. Contact with the processing area of ​​the COF product itself during the process, or the developer crystallizes in the groove and contacts the processing area of ​​the COF product itse

Abstract

The invention relates to a liquid floating spray tray for a COF wet process. The liquid floating spray tray comprises a sealed cavity, the side wall of the sealed cavity is provided with a water inletand a water outlet hole, and a developing solution enters the sealed cavity through the water inlet and is flushed out in a liquid column node through the water outlet hole to jack a COF product located at the upper portion of the water outlet hole and perform developing effect on the COF product. In the structure mentioned above, the liquid column formed by the developing liquid is configured todirectly support the COF product with no need for other structures to be in contact with the COF product for support so as to avoid usage of a traditional segment gap roller and so as not to need theside design for the segment gap roller, and the structure is simple; and moreover, it is avoided that the structure having a support effect is in contact with the COF product to pollute or damage a dry film or a circuit of the COF product so as to improve the COF product quality.
