Abstract
The invention provides a method for conducting electric insulation points. The method is used for connecting the electric insulation points on a sample with the electric insulation points with points to be connected, and comprises the following steps of: A, determining positions of the electric insulation points and the points to be connected on the sample; B, manufacturing suitable-shape carbon cement according to the positions of the electric insulation points and the points to be connected; C, washing the surface of the sample clearly and drying; and D, adhering the manufactured carbon cement on preset positions of the sample by a pair of tweezers to finish the connection of the electric insulation points and the points to be connected. According to the method disclosed by the invention, the process is simple, the operation is convenient, the conduction between the electric insulation points and the points to be connected of elements can be quickly carried out, and the efficiency of an electric test is improved; the connection of the electric insulation points and the points to be connected can be quickly changed and the fast switch of conduction positions can be realized by the method of the invention; and in addition, the method disclosed by the invention is convenient to carry out electric connection of the electric insulation points repeatedly.
Description
Technical field
The present invention relates to a kind of electric test method of components and parts, particularly a kind of conducting method of electrical isolation point.
Background technology
In failure analysis field now; Under situation in the face of the components and parts open circuit; Common way is carried out the accurate open-circuit position of electrical detection exactly to some CCs; And when further confirming that open circuit occurs in which particular location of circuit, in the industry, tend to select the method for microcell electrical isolation to carry out.But when quoting microcell electrical isolation technology, also can bring some inconveniences.When need microcell electrical isolation point and other circuit being coupled together when realizing the comprehensive consideration of components and parts circuit, because microcell point is by electrical isolation, so must make its conducting again.
Usually the method for conducting is: gold-plated.But on same interface, not only there are electrical isolation point and point to be connected when considering, also have other circuit to exist.So in gold-plated,, must cover other circuit that need not conducting with veil, only carry out gold-plated to electrical isolation district and point to be connected in order not influence the electrical situation of other circuit.This process is very complicated sometimes; Such as when point to be connected and the electrical isolation district is non-conterminous or not point-blank the time, producing of veil shape can increase workload and the working time of detecting the slip-stick artist greatly, and in case the situation that is connected that connection error or needs are tested isolating points and a plurality of points to be connected occurs; When repeatedly isolating points being tested such as needs; Just must before Gold plated Layer remove, treat to make again behind the veil gold-plated once more, finally cause the lengthening greatly of experimental period.Therefore the conducting method complex procedures of existing electrical isolation point and point to be connected, efficient is low, the test period is long, can not satisfy the needs of modern industrial society's high speed development.
Summary of the invention
In order to solve in the prior art, the conducting method complex procedures of electrical isolation point in the components and parts testing electrical property and point to be connected, the problem that efficient is low, the cycle is long, the present invention proposes following technical scheme:
A kind of conducting method of electrical isolation point, this method are used for the isolating points on the sample that has electrical isolation point is connected with point to be connected, and this method may further comprise the steps:
A, confirm the position of electrical isolation point and point to be connected on the sample;
B, make the carbon paste of suitable shape according to the position of electrical isolation point and point to be connected;
C, sample surfaces is cleaned up and dries;
D, use tweezers paste preposition on the sample with the carbon paste of making, and accomplish being connected of electrical isolation point and point to be connected.
As a kind of preferred version of the present invention, use alcohol that sample surfaces is cleaned up among the said step C.
The beneficial effect that the present invention brings is:
1, the inventive method operation is simple, and is easy to operate, can be apace to carrying out conducting between the electrical isolation point of components and parts and the point to be connected, improved the efficient of testing electrical property;
2, the inventive method can change being connected of electrical isolation point and target point to be connected fast, realizes the quick switching of conduction position;
3, the inventive method is convenient to repeatedly the electrical isolation point is electrically connected.
Embodiment
Set forth in detail in the face of preferred embodiment of the present invention down, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
The present embodiment sample is the chip of one 40 pin pins, finds need carry out conduction test between No. 7 pins and No. 8 pins through analyzing, and therefore operates as follows by the inventive method:
A, confirm the position of electrical isolation point and point to be connected on the sample, i.e. No. 7 pins and No. 8 pins, these two pins are close together close;
B, produce the carbon paste of a small rectangle according to the position of No. 7 pins and No. 8 pins;
C, with sample surfaces clean and oven dry with alcohol wash;
D, use tweezers paste preposition on the sample with the rectangle carbon paste of making, and accomplish being connected of electrical isolation point and point to be connected, promptly realize the conducting of No. 7 pins and No. 8 pins.
After having accomplished the conducting of electrical isolation point and point to be connected, can carry out corresponding testing electrical property.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
