Description

CCD line automatic exposure machine

Technical Field

Background

An exposure machine is a machine that transfers image information on a film or other transparent body to a surface coated with a photosensitive material by turning on a lamp to emit ultraviolet rays having a UVA wavelength. Exposure machine in the process of manufacturing printed circuit boards, one of the most critical processes is to transfer the negative image to the copper foil substrate. First, a layer of photosensitive material, such as liquid photosensitive glue, a photosensitive dry film for anticorrosion, etc., is coated on a substrate. Then, the photosensitive material coated on the substrate is irradiated with light to change its solubility. The resin of the non-photosensitive part is not polymerized and dissolved under the action of the developer, and the resin of the photosensitive part is left on the substrate to form an image. This process is known as exposure.

The same exposure processing that needs carries out in CCD circuit board production, and at present in the use of exposure machine, mainly be through the mode of lying to placing of CCD circuit board, consequently need positive and negative two sides to go on in proper order when the exposure, and this kind of mode leads to the exposure machine unusual loaded down with trivial details of operation when using, and extremely extravagant man-hour in addition, and exposure efficiency is low, occupies a large amount of labours simultaneously, has promoted manufacturing cost.
