Abstract
The utility model provides a green oil film edge contraposition detection device. The detection device comprises a circuit board and solder resisting film, contraposition parts for solder resisting are arranged on the circuit board; small reference discs (hereinafter referred to contraposition PADs) are arranged in the contraposition parts, the contraposition PADs are arranged on the edges of the circuit board; the contrapostion PADs are respectively arranged at the four corners of the circuit board, and contraposition PADs of the circuit board are provided with transparent contraposition areas corresponding to the solder resisting film. The utility model has the benefit that the green oil film edge contraposition detection device detects whether the solder resistance film is superposed with the circuit board through the contraposition PADs, thereby identifying whether derivation exits, realizing the purpose of accurate contraposition, improving the production efficiency, and ensuring the production quality.
Description
Technical field
Whether the utility model relates to the wiring board contraposition, relate in particular to after the resistance weldering green oil film contraposition on the detection line plate to off normal.
Background technology
In the production run of circuit board; Need the green oil film and circuit board be carried out accurate contraposition; When black film contraposition is used in resistance weldering at present since effectively in the unit the black film can't discern PAD (the contraposition reference point on the circuit board) under being in the light a little; Very easily cause, thereby cause wiring board to be washed because of off normal is returned to off normal.Improve production cost, reduce production efficiency.
Summary of the invention
In order to solve problem in the prior art, the utility model provides a kind of green oil film limit to level detecting apparatus, comprises the wiring board and the resistance weldering film; Said wiring board is provided with the resistance weldering and uses the contraposition parts; Being provided with reference to roundel in the said contraposition parts, is contraposition PAD to call in the following text with reference to roundel, and said contraposition PAD is arranged on the edges of boards of said wiring board; The place, four angles of each wiring board is provided with contraposition PAD respectively, and the contraposition PAD of the corresponding said wiring board of the said resistance weldering film is provided with transparent contraposition district.
As the further improvement of the utility model, each said resistance weldering is with being provided with four contraposition PAD that are arranged side by side in the contraposition parts.
As the further improvement of the utility model, said contraposition PAD, the diameter of said contraposition PAD are 0.6mm, and contraposition PAD spacing is 0.5mm.
As the further improvement of the utility model, said wiring board is provided with the resistance weldering and uses the contraposition parts to be the Wu Tong district, and the contraposition PAD in it is for there being the copper district, and contraposition PAD is 0.35mm apart from the distance of contraposition edge-of-part.
As the further improvement of the utility model, the diameter in the transparent contraposition district on the said resistance weldering film is than the big 0.03mm of diameter of said contraposition PAD.
The beneficial effect of the utility model is: whether the green oil film limit of the utility model is detected the resistance weldering film to level detecting apparatus through contraposition PAD and is overlapped with wiring board; Thereby whether identification is to off normal; Reach the purpose of accurate contraposition, production efficiency is provided, guarantee product quality.
[description of drawings]
Fig. 1 is the structural representation of the utility model green oil film limit to the wiring board in the level detecting apparatus.
[embodiment]
Below in conjunction with description of drawings and embodiment the utility model is further specified.
Liquid photopolymerizable solder resist (being commonly called as green oil) is a kind of protective seam, is coated on the circuit and base material that printed circuit board need not weld.Purpose is the formed line pattern of long-term protection.The film: the egative film in the plate-making of finger mark brush.
The utility model provides a kind of green oil film limit to level detecting apparatus; Comprise the wiring board and the resistance weldering film, said wiring board is provided with the resistance weldering and uses the contraposition parts, is provided with reference to roundel in the said contraposition parts; To call in the following text with reference to roundel is contraposition PAD; Said contraposition PAD is arranged on the edges of boards of said wiring board, and the place, four angles of each wiring board is provided with contraposition PAD respectively, and the contraposition PAD of the corresponding said wiring board of the said resistance weldering film is provided with transparent contraposition district.Each said resistance weldering is with being provided with four contraposition PAD that are arranged side by side in the contraposition parts.Said contraposition PAD, the diameter of said contraposition PAD are 0.6mm, and contraposition PAD spacing is 0.5mm.Said wiring board is provided with the resistance weldering and uses the contraposition parts to be the Wu Tong district, and the contraposition PAD in it is for there being the copper district, and contraposition PAD is 0.35mm apart from the distance of contraposition edge-of-part.The diameter in the transparent contraposition district on the said resistance weldering film is than the big 0.03mm of diameter of said contraposition PAD
As shown in Figure 1: as to add that at the circuit edges of boards hindering weldering uses contraposition PAD101; Contraposition PAD101 is the copper of small cylindrical, and its diameter is about 0.6mm, and the spacing of each PAD is 0.5mm; PAD is 0.35mm apart from the copper interval distance; Four outer rectangles of PAD are Wu Tong district 103 among the figure, and rectangle is outer for the copper district is arranged, and have place, copper district to be provided with silk-screen Guan Weikong 102.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
