Description

Technical Field

[0001] This utility model belongs to the field of ceramic copper-clad laminate dewatering technology, and relates to a non-contact dewatering device based on the Coanda effect. Background Technology

[0002] During the production process, residual moisture may remain on the surface of the ceramic copper-clad laminate. This moisture can cause corrosion of the copper layer, affecting the conductivity and mechanical strength of the circuit board, and consequently impacting the overall performance and reliability of the product. Effective moisture removal ensures the surface of the ceramic copper-clad laminate is dry and clean, thereby improving product quality and reliability.

[0003] Currently, water-absorbing sponges are used to remove excess water from the copper surface and deep trenches, forming a thin and uniform water film on the surface. During the hot air blowing process, the moisture can be dried quickly and evenly, resulting in a copper surface with a uniform appearance and no water stains or oxidation.

[0004] However, after prolonged contact between the absorbent sponge and the product, there is a risk of contaminating the product surface. For some products with deep grooves, the water in the grooves is difficult for the absorbent sponge to reach and absorb completely. During subsequent hot air drying, the water in the grooves is blown to the surface by the hot air, resulting in uneven surface moisture and inconsistent drying time. Ultimately, due to the coffee ring effect, water stains or oxidation may appear on the surface. Utility Model Content
