Abstract

The invention discloses a fluorescence leak detection method. Detection is completed by the following steps that fluorescent glue is filled into a syringe needle tubing, and the syringe needle tubing is prepared for further use; a proper perforation position is searched in a sample for leak detection; a dye in the syringe needle tubing is extruded out of the internal of the sample under certain pressure at the searched perforation position; a camera or pick-up head is used to record the leak position of the sample; and the searched leak position of the sample is observed via a micro slice, gap in the assembling process of an electronic produce is found, and the leak detection process of the electronic product is realized. The fluorescence leak detection method has the advantages that the leak position can be found accurately, significant basis is provided for improvement of the product assembly process, the leak detection process is rapid, a detection structure is correct, operation is simple, the working efficiency is high, and the waterproof performance of the electronic product can be developed.

Description

A kind of fluoroscopic leak test method
Technical field
The present invention relates to a kind of leak detecting, be specially a kind of fluoroscopic leak test method, belong to detection method applied technical field.
Background technology
Development along with science and technology, single molecular fluorescence leak detecting is at analytical chemistry, the fields such as life sciences are subject to very big attention, but period development is slower, development along with detection technique of fluorescence, hereafter Single Molecule Detection is by developing under cryogenic conditions and can at room temperature carry out, tend to gentle, and realize liquid stream successively, single molecule fluorescence detection in microdroplet and solution, this real-time measurement makes single molecular fluorescence record not only reflect the specific molecular time of staying at detecting area, and comprise characteristic interval information, this unimolecule spectrographic method can be used for the unimolecule of high flux examination disease markers and monitors the interaction of single molecule, Fluorescein leakage test is the air-tightness that the fluorescein amount penetrated after being exposed to tested material by detection evaluates tested material, water resistance test for Current electronic product has extremely important effect, and there is a lot of weak point in the water resistance detection method of electronic product at present, electronic product leak hunting method as traditional typically uses what red ink test carried out detecting, detection after bake dry doubling is disassembled test sample and is found leakage point, this way is also difficult to can find leak source accurately, and this method causes sample must take searching apart, require a great deal of time and hunt leak, inefficiency, therefore, for the problems referred to above, a kind of fluoroscopic leak test method is proposed.
Summary of the invention
The purpose of the present invention is that provides a kind of fluoroscopic leak test method to solve the problems referred to above.
The present invention is achieved through the following technical solutions above-mentioned purpose, a kind of fluoroscopic leak test method, completes leak detection process by following steps:
A, standby glue, will pour into fluorescent glue, ready for use inside injection needle;
B, perforate, in testing sample correct position perforate;
C, injecting glue, find in b and use injection needle from position of opening and under a certain pressure the stain within injection needle to be squeezed out from sample interior on the position of perforate;
D, record, use sample leakage position in camera or photographic head record c;
E, looking for leakage, by micro-sections observation d sample leakage position found, finding the gap of electronic product assembling process, thus realizing the leak detection process of electronic product.
Preferably, without other foreign material inside injection needle in described gum, and the fluorescent glue amount within injection needle is more than the volume of sample interior.
Preferably, the hole diameter of described perforate and injection needle equal diameters.
Preferably, described camera or photographic head to detect each orientation of sample.
Preferably, described in look for the position that the micro-cutting machine that leaks through in journey is observed to sample rationally, observe through many sub-samplings.
The invention has the beneficial effects as follows: this kind of fluorescence method of leaking hunting can find leak source position accurately, find to improve for the process of assembling product to provide important foundation, and process of hunting leak is quick, detection structure is accurate, simple to operate, work efficiency is high, and the development for the water resistance aspect of electronic product has extremely important effect, is suitable for promoting the use of.
Detailed description of the invention
