Abstract
The utility model discloses an exposing energy uniformity testing device comprising an exposure disc, wherein, a plurality of base plates are arranged uniformly on the exposure disc, and exposure guide rulers are arranged on two sides of each base plate. The utility model is characterized in that the exposure guide rulers are arranged on the copper-clad plates on two sides of each base plate, and the copper-clad plates are uniformly placed on the exposure disc. Before the exposure of a PCB, exposing uniformity test is performed on an exposure machine to control the exposing uniformity , thereby achieving the purpose of uniform exposure. Compared with the prior art, the exposing energy uniformity testing device provided by the utility model is low in cost, simple to manufacture, convenient and quick to operate, and is reusable.
Description
Technical field
The utility model relates to the pcb board exposure technique, and what be specifically related to is a kind of exposure energy homogeneity test device.
Background technology
In the pcb board manufacturing process, exposure is a very important link, its fundamental purpose be through the light source effect with the image transfer on the original negative film to the sensitization base plate.Because exposure is that ultraviolet light is seen through the process that film egative film makes photosensitive resist agent material generation photopolymerization reaction, therefore require exposure energy evenly necessary, otherwise on pcb board, will produce problems such as open circuit, short circuit, plating and live width, line gap instability, serious then can influence the quality of product.In existing exposure technique, even in order to ensure exposure energy, UV energy meter commonly used detects before exposure, but the UV energy meter costs an arm and a leg, and causes the production cost height.
Summary of the invention
For this reason, the purpose of this utility model is to provide a kind of with low cost, easy to use being used to measure the inhomogeneity proving installation of exposure energy.
For achieving the above object, the utility model is mainly by the following technical solutions:
A kind of exposure energy homogeneity test device comprises shutter (1), evenly is provided with a plurality of substrates (2) on the described shutter (1), and the two sides of described substrate (2) is provided with exposure guide rule (3).
Wherein said substrate (2) is copper-clad plate, and this copper-clad plate two sides is pasted with dry film, by this dry film pasting exposure guide rule (3) is arranged.
The utility model is by being arranged on exposure guide rule in the copper-clad plate on substrate two sides, and this copper-clad plate evenly is placed on the shutter.Before the pcb board exposure, the exposition uniformity of exposure machine is tested,, reached the uniform purpose of exposure with control exposure uniformity coefficient.Compared with prior art, it is low to the utlity model has cost, makes simply, easy to operate, quick, advantage such as can reuse.
Description of drawings
Fig. 1 is a working state schematic representation of the present utility model.
Fig. 2 is a structural representation of the present utility model.
Identifier declaration among the figure: shutter 1, substrate 2, exposure guide rule 3.
Embodiment
The utility model, is tested by the substrate and the exposure guide rule that evenly are positioned on the shutter before to the exposition uniformity of exposure machine by the pcb board exposure, with the exposure uniformity coefficient of control exposure machine, thereby reaches the uniform purpose of exposure.
For setting forth thought of the present utility model and purpose, the utility model is described further below in conjunction with the drawings and specific embodiments.
See also Fig. 1, shown in Figure 2, the utility model provides a kind of exposure energy homogeneity test device, this device was mainly used in before pcb board is exposed, earlier the exposition uniformity of exposure machine is tested, to avoid producing quality problem such as open circuit, short circuit, plating and live width, line gap instability because of the inhomogeneous pcb board that causes of exposure machine exposure.
Wherein this device mainly includes shutter 1, evenly is provided with a plurality of substrates 2 on the described shutter 1, and described substrate 2 is copper-clad plate, and this copper-clad plate two sides is provided with dry film, exposure guide rule 3 then by above-mentioned dry film pasting in copper-clad plate.Described exposure guide rule is in the printed circuit board production run, and liquid towards sensitization circuit printing ink, liquid photosensitive welding resistant printing ink have a comparatively accurately indispensable instrument of conditions of exposure control.
Substrate is two-sided FR-4 copper-clad plate of posting dry film, and its physical dimension is 160mm * 200mm, and thickness of slab is 1.0mm～1.6mm.
Concrete operation method of the present utility model is: at first respectively put a substrate on the central area of shutter and corner location; Start exposure machine, set exposure energy, expose according to processing parameter; More than the static 15min in exposure back, will develop, accurately read the lattice number that develops on each substrate through the substrate of overexposure; Then according to formula: energy deviation value=(lattice are counted mxm.-Ge and counted minimum)/lattice are counted mxm. * 100%, calculate the exposure energy deviate: if energy deviation value≤20%, show to reach the exposition uniformity requirement, otherwise be exactly not reach requirement, also need adjust.
More than be that a kind of exposure energy homogeneity test device provided by the utility model is described in detail, used specific case herein structural principle of the present utility model and embodiment are set forth, above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
Claims (2)
1. an exposure energy homogeneity test device is characterized in that comprising shutter (1), evenly is provided with a plurality of substrates (2) on the described shutter (1), and the two sides of described substrate (2) is provided with exposure guide rule (3).
2. exposure energy homogeneity test device according to claim 1, its feature is copper-clad plate at described substrate (2), this copper-clad plate two sides is pasted with dry film, by this dry film pasting exposure guide rule (3) is arranged.
