4. one kind includes the connection version that non-notch according to claim 1 and 2 etches partially reinforcement steel disc, it is characterized in that, the positive and negative that also comprises positive and negative and described reinforcement steel disc body (1) is the quadra (3) in a plane all, dowel (4) and brace (5), the parallel some dowels (4) that are connected with of inside offside equi-spaced apart of described quadra (3), described non-notch etches partially reinforcement steel disc and is located between dowel (4) and dowel (4) and forms in gap (6), one end of described brace (5) is connected on dowel (4), another of described brace (5) is connected to the middle part of the corresponding end face of square groove (2) that described non-notch etches partially reinforcement steel disc and the length that its transverse width is less than square groove (2) to side.
5. include the connection version that non-notch according to claim 4 etches partially reinforcement steel disc, it is characterized in that, the transverse width of described brace (5) is than the little 0.05-0.1mm of length of square groove (2).
6. non-notch according to claim 5 etches partially a preparation method for the connection version of reinforcement steel disc, it is characterized in that, comprises the steps:
Step 1: design configuration, is depicted as the film
Use the single non-notch only of wiring board industry professional software (as CAM350 or GENESIS2000) design to etch partially the connection domain paper that reinforcement steel disc drawing and non-notch etch partially reinforcement steel disc, the connection domain paper that ready-made non-notch is etched partially to reinforcement steel disc is derived wiring board industry universal form, then by optical plotter, the wiring board industry universal form light of above-mentioned derivation is plotted to the end, wiring board special-purpose film top two-layer;
Step 2: steel plate pastes dry film, with film exposure, then develops
By connection version dimensions, cut steel plate, positive and negative at steel plate all sticks dry film, then the steel plate that positive and negative is all posted to dry film is clipped between the bottom film of top and the medicine face of the top bottom film is oppositely arranged, by ORC5KW exposure machine, the pattern exposure of the film is transferred on dry film, then positive and negative is all shifted to the steel plate of dry film of the pattern of the film and put into horizontal developing machine, steel plate passes through horizontal developing machine by the speed with 2.8-3.2m/min, the potassium hydroxide liquid medicine that the place of film pattern will be 0.8%-1.4% by mass percent that exposed on steel plate develops out,
Step 3: by the steel plate after developing by the pattern etching of having developed out
The steel plate having developed is put into iron chloride acid etching machine; steel disc passes through iron chloride acid etching machine by the speed with 0.7-0.8m/min; it is the iron chloride liquid medicine corrosion etching that 150-190g/L, concentration of hydrochloric acid are 0.2-0.4mol/L that the place of the steel plate that oneself development is exposed can be subject to ferric ion concentration; there is the place of dry film can not be subject to liquid medicine corrosion because being protected; steel plate just according to the pattern etching of having developed out like this; then undeveloped dry film is taken off and washed off, just obtain the connection version that non-notch etches partially reinforcement steel disc.
