Description
Technical field
The utility model relates to the circuit board technology field, relates in particular to the two-sided synchronous exposure machine of a kind of circuit board.
Background technology
In general, the step that forms electronic circuit on the circuit board comprises: at first design the distribution of electronic circuit, and draw out the last original copy and the following original copy of electronic circuit, be used for exposure and use; Secondly a two-sided circuit board that is laid with copper film is carried out surface clean, to remove the oil stain dirt; Punch then, comprise the jack of electronic component and registration holes etc., and at coated on both sides one deck photosensitive dry film of circuit board, again last original copy with following original copy is corresponding with circuit board exposes, utilize developer with the part cleaning removal that do not need on the photosensitive dry film to keep to expose copper film; With chemical reagent the copper film that exposes on the circuit board is etched away at last, can finish through green lacquer, step such as anti-welding again.
Fig. 1 be in the prior art circuit board exposure machine at the structural representation of the second exposure stage open mode.Fig. 2 be in the prior art circuit board exposure machine at the structural representation of the first exposure stage open mode.As depicted in figs. 1 and 2, fluorescent tube 20 and following fluorescent tube 21 are installed in the exposure room 101 of this exposure machine 10, irradiation by last fluorescent tube 20 and 21 pairs of circuit board 30 upper and lower surfaces of following fluorescent tube, the photosensitive dry film on these circuit board 30 two sides will not hardened because being subjected to light by the part of last original copy and the covering of following original copy, because last fluorescent tube 20 and following fluorescent tube 21 are to expose synchronously in the two sides, therefore whether go up fluorescent tube 20 and following fluorescent tube 21 equates with luminous range and light application time between circuit board 30 two sides, can directly influence the synchronous hardenability of circuit board 30 two sides photosensitive dry films, and then influence the quality of circuit board 30.
This exposure machine 10 be equipped with first exposure stage 40 and second exposure stage, 41, the first exposure stage 40 be higher than 41, two exposure stage of second exposure stage can be by track at exposure room 101 with change turnover between the pallet 102.First exposure stage 40 and second exposure stage 41 are transparent platform, can place down original copy, and are provided with first transparent cover body 400 and second transparent cover body 401 respectively, can be used to place original copy.
During work, the circuit board 30 of preparing exposure can be placed on second exposure stage 41, cover second transparent cover body 401 again, push the exposure that exposure room 101 carries out 3 to 5 seconds then, send exposure room 101 at last to changing pallet 102.Then start first transparent cover body 400 again and in first exposure stage 40, place circuit board 30, and push exposure room 101 exposures, so alternately turnover exposure.
Because two exposure stage are not to be on the same surface level; two fluorescent tubes in the exposure room 101 have notable difference apart from the distance of circuit board 30; so need go up the irradiation time of fluorescent tube 20 and following fluorescent tube 21 by computer control; for example; need close in advance during the short circuit board 30 of last fluorescent tube 20 respective distances; close and when the short circuit board 30 of last fluorescent tube 20 respective distances, need prolong, can reach exposure quality average, normalization to guarantee circuit board 30 two sides exposures.
But control the standard that this mode is difficult to reach accurate exposure by computer, because the time shutter of circuit board 30 in exposure room 101 only has 3 to 5 seconds, last fluorescent tube 20 and following fluorescent tube 21 are obvious with the distance difference on circuit board 30 two sides, control the time shutter by computer has any problem very much, and go up fluorescent tube 20 degree of aging different and the problem of voltage instability with the following fluorescent tube 21 long-term meeting of use formation, computer is more difficult control just.
Like this, the fault rate that burr or linear deformation appear in the electronic circuit that circuit board 30 is made is very high, is difficult to the requirement that reaches high-accuracy, high-quality, and two exposure stage all need to start transparent cover body and could place circuit board 30, causes work efficiency lower.
