Description

Technical Field

[0001] The utility model relates to the technical field of circuit board processing, in particular to a circuit board developing device. Background Art

[0002] Circuit boards can be called printed circuit boards or printed circuit boards. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can be divided into three major categories according to the number of layers: single-sided boards, double-sided boards, and multi-layer circuit boards.

[0003] When manufacturing circuit boards, they usually need to undergo processes such as exposure, development, and etching. Development is the process of dissolving the exposed area with a developer to display the exposed area. Traditional development mostly involves directly spraying the developer on the surface of the circuit board and then wiping it. This does not fully utilize the developer, resulting in serious waste of developer, uneven coverage, and is inconvenient for adaptive locking and fixing according to circuit boards of different sizes.
