Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of PCB board production, and particularly relates to a vertical developing machine with self-adaptive adjustment of guide wheel spacing. BACKGROUND

[0002] Film pressing, exposure and development technology is a commonly used technology in the field of electronic manufacturing, especially in the manufacturing process of printed circuit boards (PCB). The basic steps include three stages of film pressing, exposure and development. First, in the film pressing stage, the photosensitive material (usually dry film) is pressed onto the copper foil. This step is to tightly combine the dry film with the copper foil so that the required circuit pattern is formed in the subsequent exposure and development process. In the development stage, the unexposed dry film is dissolved by using the weak alkaline of the developing solution, and the exposed part is washed away to form the required circuit pattern. In the whole process, the dry film plays a key role. It is a special photosensitive material that can undergo chemical reaction in the exposure process to form the required circuit pattern in the development stage. At the same time, the copper foil as the basic material of the circuit is tightly combined with the dry film to form the final circuit board.

[0003] The developing machine is an essential device in the development stage. In the prior art, the distance between the two rollers of the guide wheel assembly in the developing machine is fixed.
