Problems solved by technology

[0002] With the development of science and technology, single-molecule fluorescence leak detection has received great attention in the fields of analytical chemistry and life sciences, but the development has been slow during this period. With the development of fluorescence detection technology, single-molecule detection has developed from low temperature conditions to possible Performed at room temperature, tends to be gentle, and successively realizes single-molecule fluorescence detection in liquid streams, microdroplets, and solutions. Intermittent information, this single-molecule spectroscopy method can be used for high-throughput screening of single molecules of disease markers and monitoring of single-molecule interactions. To evaluate the airtightness of the test object, it plays an extremely important role in the waterproof performance test of current electronic products. However, the current waterproof performance detection method of electronic products has many shortcomings. For example, the traditional electronic product leak detection method usually uses The red ink test is used for detection. After the test, the test sample is dried and disassembled to find the leak point. This method is still difficult to accurately find the leak point, and this method requires the sample to be disassembled to find it, which takes a lot of time. Leak detection, low work efficiency, therefore, a fluorescent leak detection method is proposed to solve the above problems

Embodiment

[0016] Embodiment, a fluorescent leak detection method, the leak detection process is completed through the following steps:

[0017] Step 1: Fill the inside of the injection needle with fluorescent glue, ready for use;

[0018] Step 2: Open a hole at a suitable position of the sample;

[0019] Step 3: Use the injection needle tube to squeeze out the dye inside the injection needle tube from the inside of the sample at the position of the hole found in step 2 under a certain pressure;

[0020] Step 4: Use a camera or video camera to record the location of the sample leak in step 3;

[0021] Step 5: Observing the leak position of the sample found in step 4 through the microsection, and finding the gap in the assembly process of the electronic product, so as to realize the leak detection process of the electronic product.

[0022] As an optimized technical solution of the present invention, in the first step, there is no other debris inside the injection needle, and the amount...

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.
