Embodiment Construction
[0028] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0029] like figure 1 As shown, a kind of solder joint quality detection method of the present invention comprises the following steps:
[0030] S1. According to the actual welding requirements, set the welding temperature value on the soldering station, and record the corresponding power and temperature when the soldering station reaches the welding temperature value; among them, the soldering station can choose an intelligent lead-free soldering station so that it can automatically record and store the entire Power changes during welding, temperature fluctuations, length of welding time;
[0031] S2. Manual reference welding, as a reference solder joint, re...

The invention relates to a welding spot quality detection method, which comprises the steps of S1, setting a welding temperature value on a welding table, and recording corresponding power and temperature when the welding table reaches the welding temperature value; S2, welding a reference welding spot, and recording change data of power and temperature and welding time in the welding process; S3,after welding is completed, taking power and temperature change data and welding time data recorded in the welding process as reference values; S4, welding a conventional welding spot, and recordingchange data of power and temperature and welding time in the welding process; S5, when the power and the temperature return to the power and the temperature value recorded in the step S1 again, representing that the current welding is finished, and stopping recording; S6, calculating the similarity rate of the conventional welding spot and the reference values; and S7, setting a weight ratio to obtain the percent of pass of the conventional welding spot. The detection result obtained by the detection method is more accurate, reasonable and scientific.
Description
technical field [0001] The invention relates to the technical field of solder joint detection, in particular to a method for detecting solder joint quality. Background technique [0002] In the process of manufacturing or repairing the PCB board of electronic products, it is necessary to solder the electronic components on the PCB board. The current manual soldering method is still the most commonly used and most common welding method, but due to the artificial and objective factors in the manual soldering process, it is easy to As a result, the welding quality is uneven, and it is difficult to ensure the consistency of the quality of each solder joint in the welding scene with relatively high requirements, resulting in the appearance of defective products. Therefore, it is necessary to remind the quality of the solder joints during the manual welding process, and to evaluate and record the quality of the solder joints after welding. [0003] The traditional detection metho...
