Description
Technical field
The utility model relates to photoresistance dry film production technical field, particularly relates to a kind of for checking the exposure machine of laser direct imaging dry film quality.
Background technology
At present, because laser direct imaging exposure machine has the advantages such as high-effect, making circuit precision is high, contraposition is simply accurate, the use in the Precision wire PCB making that HDI, soft board and soft or hard combine obviously increases.And the dry film being applicable to laser direct imaging exposure machine is also produced more and more.
For dry film manufacturing enterprise, producing the special D/F of laser direct imaging needs to use laser direct imaging exposure machine to carry out the inspection of product quality.But because current laser direct imaging exposure machine output is less, the price of this exposure machine is very expensive, dry film manufacturing enterprise is that use printed circuit board (PCB) enterprise uses, the typical exposure machine of relative low price carries out the inspection of product quality mostly for this reason.But, be in very large difference between typical exposure machine and laser direct imaging exposure machine, be mainly manifested in following two aspects:
(1) laser direct imaging exposure machine uses laser, and the ultraviolet light launched is Single wavelength (wavelength is respectively 365nm or 405nm); And typical exposure machine uses mercury lamp, the ultraviolet light launched is multi-wavelength (wavelength is 250 ~ 450nm).The special D/F of laser direct imaging has certain absorption to specific wavelength, uses typical exposure chance to cause the special D/F resolution of laser direct imaging to be deteriorated.
(2) exposure energy of the special D/F of laser direct imaging is lower, is generally 10 ~ 20mJ/cm
2.If the energy > 20mJ/cm of laser direct imaging exposure machine
2can production capacity be affected, and at 10 ~ 20mJ/cm
2energy comparison is stablized, and does not affect production capacity; And typical exposure function is at 10 ~ 20mJ/cm
2instability, is difficult to control at specific energy, causes the resolution of the special D/F of laser direct imaging to be deteriorated.
As can be seen here, use typical exposure machine to carry out Quality Detection to the special D/F of laser direct imaging and there is very large drawback, for verifying whether the special D/F of laser direct imaging that produces is certified products, it is very difficult whether can to use in special laser direct imaging exposure, obviously cannot meet the production development demand of the special D/F of laser direct imaging.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of simplicity of design, easy to make, is easy to the exposure machine for checking laser direct imaging dry film quality realized, to meet the production development demand of the special D/F of laser direct imaging.
The purpose of this utility model is achieved by the following technical programs:
It is a kind of for checking the exposure machine of laser direct imaging dry film quality that the utility model provides, for having the typical exposure machine of framework, copper coin; Comprise track, optical filter, gusset plate in addition; Described Orbital Symmetry is arranged on the both sides in framework, and described gusset plate is arranged on the periphery of optical filter; The top and bottom of described gusset plate are corresponding with track and activity plugs in orbit, and the position of described optical filter is corresponding with copper coin.
The utility model adopts optical filter to improve typical exposure machine wavelength of light, is transformed by the ultraviolet light of multi-wavelength and makes it to export, to be applicable to the inspection of the special dry film of laser direct imaging with 365nm or 405nm Single wavelength.
Further, the utility model also comprises light damping plate, and described light damping plate is superimposed upon on optical filter, to reduce UV energy as required.
In such scheme, the end of track described in the utility model is provided with limited block, with the position of stable optical filter/gusset plate.
The utility model has following beneficial effect:
(1) the utility model by simple designs improve can realize different wave length export, processing and easy to make, be easy to realization, be applicable to the use of variety classes laser direct imaging dry film.
(2) the utility model is convenient to change optical filter, can select the optical filter of different wave length according to actual needs or superpose different types of light damping plate, thus reaches the effect changing wavelength and energy.
Accompanying drawing explanation
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the A-A cut-open view of Fig. 1.
In figure: framework 1, copper coin 2, track 3, filter 4, gusset plate 5, limited block 6, LDI dry film 7
Embodiment
Fig. 1 and Figure 2 shows that the utility model is a kind of for checking the embodiment of the exposure machine of laser direct imaging dry film quality, as shown in Figure 1, for having the typical exposure machine of framework 1, copper coin 2, comprises track 3, filter 4, gusset plate 5 in addition.
Track 3 is symmetricly set on the both sides in framework 1, and the end of track 3 is provided with limited block 6 (see Fig. 2, or end is closed).Gusset plate 5 is arranged on the periphery of optical filter 4, and the activity corresponding with track 3 of the top and bottom of gusset plate 5 is plugged in track 3.The position of optical filter 4 is corresponding with copper coin 2.
In addition, the optical filter of different wave length can be selected according to actual needs, or superpose the use of different types of light damping plate to reach the effect changing wavelength and energy.
As shown in Figure 2, when using the present embodiment, LDI dry film 7 covers copper coin 2 surface, and during exposure, the direct mating plate 4 after filtration of light arrives the LDI dry film 7 on copper coin 2 surface, thus realizes the exposure of LDI dry film 7.
