Abstract
A carbon oil leak print test PAD of a PCB board comprises a first pad network, a second pad network and a carbon oil strip (4) used for connecting the first pad network and the second pad network, wherein the first pad network comprises a first test pad 1 (1), a first circuit (2) connected with the first test pad 1 (1) and a first test pad 2 (3) connected with the first circuit (2); the second pad network comprises a second test pad 1 (11), a second circuit (21) connected with the second test pad 1 (11) and a second test pad 2 (31) connected with the second circuit (21). The carbon oil leak print test PAD has a simple and practical design, test needles of the first test pad 1 and the second test pad 1 are connected by an external test fixture, and the test fixture tests the leak print situation, pass means normal. Thus the open circuit points of the network are searched by the way to judge whether the carbon oil is printed or not.
Description
Technical field
The utility model relates to the pcb board field tests, and the special standby carbon oil that relates to a kind of pcb board is bitten and tested PAD.
Background technology
Substantially the most also be most crucial parts as electronic product, pcb board is widely used on each electronic product and main equipment and device, usually, according to customer requirement, manufacturer need to be laid in circuit on the substrate of pcb board, in common process, the Industrial Engineering of test pcb board can be set all generally.
The seal carbon oil refers to adopt screen printing technique, stamps carbon oil in the position of pcb board appointment, forms the qualified carbon film with certain resistance and replace original resistive element after oven for solidifying is completed.Its manufacture craft and character silk-screen are similar, and difference is only that carbon oil has good electric conductivity, are semiconductor materials and the character silk-screen adopts, only play sign and every the effect of weldering.
Due to do not print before carbon oil test PAD with printed after the electric current of carbon oil test PAD have or not and exist differently, therefore to the test of PCB carbon oil plate particularly key, also there is no now a kind of proving installation of PCB carbon oil plate, slightly inadequate in this area.
Summary of the invention
Based on this, be necessary to provide a kind of carbon oil of the pcb board test PAD that bites.
The technical solution of the utility model is as follows:
A kind of carbon oil of pcb board is bitten and is tested PAD, comprises a pad network, the 2nd pad network and the carbon oil bar 4 of be connected the centre described pad network of connection and described the 2nd pad network;
Further, a described pad network comprises the first test pad1 1, the first circuit 2 that is connected with described the first test pad1 1 and the first test pad2 3 that is connected with described the first circuit 2;
Further, described the 2nd pad network comprises the second test pad1 11, the second circuit 21 that is connected with described the second test pad1 11 and the second test pad2 31 that is connected with described the second circuit 21.
Further, described the first test pad2 2 connects by described carbon oil bar 4 in the middle of test pad2 21 with being connected.
Concrete, described the first circuit 2 and the second circuit 21 are a copper cash.
Concrete, described carbon oil bar width is 2.2mm.
The utility model is with respect to prior art, its advantage and beneficial effect are: this simplicity of design is practical, can connect the first test Pad1 and the second testing needle of testing on pad1 by outside measurement jig, pass is normal when tool is tested, with this open circuit point of coming Network Search, be determined with without biting carbon oil.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of PCB(Printed Circuit Board; Printed circuit board (PCB)) carbon oil of plate is bitten and is tested the PAD(pad), comprise a pad network, the 2nd pad network and the carbon oil bar 4 of be connected the centre described pad network of connection and described the 2nd pad network; A described pad network comprises the first test pad1 1, the first circuit 2 that is connected with described the first test pad1 1 and the first test pad2 3 that is connected with described the first circuit 2; Described the 2nd pad network comprises the second test pad1 11, the second circuit 21 that is connected with described the second test pad1 11 and the second test pad2 31 that is connected with described the second circuit 21.
In a preferred embodiment, the size of the first test Pad1 1 and the second test pad1 11 is 2.0*2.0mm, the size of the first test Pad2 2 and the second test pad2 21 is 1.5*1.5mm, the first test Pad1 1 is connected with the first circuit 3 that the first 2 of Pad2 of test are 4mm with outer live width size, form consolidated network, i.e. a pad network; The second test Pad1 11 is connected with the second circuit 31 that the second 21 of test Pad2 are 4mm with outer live width size equally, form consolidated network, i.e. the 2nd pad network, welding resisting layer is according to normally windowing, the carbon oil layer increases carbon oil bar 4, its width is 2.2mm, and will stamp carbon oil between two Pad2 by printing technology, does not print carbon oil front for opening a way; Form consolidated network after having printed carbon oil.In this preferred embodiment, described the first circuit 2 and the second circuit 21 are a copper cash, and described carbon oil bar 4 width are 2.2mm.
This simplicity of design is practical, during use, can connect the first testing needle of testing on pad1 and the second test pad1 by outside measurement jig, and pass is normal when tool is tested, and with this open circuit point of coming Network Search, is determined with without biting carbon oil.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
