CCD circuit automatic exposure machine

Abstract

The invention relates to the technical field of exposure machines, in particular to a CCD circuit automatic exposure machine. The CCD circuit automatic exposure machine comprises a base, a gear motor,a turntable, a lower clamping seat, a sleeve, a limiting block, a tension spring, a movable rod, an upper clamping seat, an exposure box, an outer cylinder, a light-transmitting plate, an exposure lamp, an adjusting block, an electric push rod, a closing plate and a cabinet, wherein the gear motor is located in the middle of the bottom of the base, the output end of the gear motor extends to theposition above the top of the base, the output end of the gear motor is in transmission connection with the middle of the bottom of the turntable, and the middle of the top of the turntable is fixedlyconnected with the bottom of the lower clamping seat. The purpose of carrying out double-sided exposure on the CCD circuit board at one time is achieved, the whole process is simple and convenient, and a large amount of working time is saved, so that the production efficiency is improved, the labor force is reasonably allocated, the production cost and the labor cost are reduced, and the exposurequality of the CCD circuit board is ensured.

Description

technical field [0001] The invention relates to the technical field of exposure machines, in particular to a CCD circuit automatic exposure machine. Background technique [0002] Exposure machine refers to the machine equipment that transfers the image information on the film or other transparent body to the surface coated with photosensitive material by turning on the light and emitting ultraviolet rays of UVA wavelength. One of the most critical processes in the printed circuit board manufacturing process is to transfer the negative image to the copper foil substrate. First, a layer of photosensitive material, such as liquid photosensitive glue, photosensitive anti-corrosion dry film, etc., is coated on the substrate. Then, the photosensitive material coated on the substrate is irradiated with light to change its solubility. The resin in the non-photosensitive part does not polymerize or dissolve under the action of the developer, and the resin in the photosensitive part...

Problems solved by technology

[0003] Exposure treatment is also required in the production of CCD circuit boards. At present, in the process of using the exposure machine, the placement of CCD circuit boards is mainly through the way of lying flat, so the front and back sides need to be sequentially exposed during exposure. The method makes the operation of the exposure machine extremely cumbersome, and it is extremely wasteful of working hours, the exposure efficiency is low, and it takes up a lot of labor, which increases the production cost.
