What are the main methods of welding inspection? Third party testing

Date:2023-04-14 14:30:47Views:597

Weldability welding inspection is a very important part of the manufacturing process of electronic products. In order to ensure product quality and reliability, scientific inspection methods need to be adopted. If you want to gain a deeper understanding of solderability testing, this article will summarize relevant knowledge and provide you with a comprehensive understanding and understanding.

Classification of Weldability Welding Inspection Methods

The weldability welding inspection methods are mainly divided into the following types:

1. Physical inspection method: The physical inspection method mainly inspects the welding quality through physical means, such as observing the welding interface through a microscope, and determining the welding strength through hardness testing.

2. Chemical inspection methods: Chemical inspection methods mainly use chemical reactions to inspect the quality of welding, such as using titration method to inspect the quality of solder balls, and using pH test to inspect the acidity of welding.

3. Optical inspection method: The optical inspection method mainly uses optical means to inspect the welding quality, such as observing the welding interface through a magnifying glass, observing the welding traces through ultraviolet light, etc.

4. Electronic inspection methods: Electronic inspection methods mainly use electronic means to inspect welding quality, such as testing welding resistance through instruments and verifying welding current through current testing.

Characteristics of different inspection methods

The characteristics of different inspection methods are as follows:

1. Physical inspection method: The physical inspection method is easy to operate and has a low cost, and can quickly detect welding quality. However, physical observation of the welding interface is required, making it difficult to intuitively understand the welding process and welding quality.

2. Chemical inspection methods: Chemical inspection methods can intuitively understand the welding process and welding quality, but require chemical reactions, which are relatively complex and costly.

3. Optical inspection method: Optical inspection method can intuitively understand the welding process and welding quality, with simple operation and low cost, but requires the use of optical equipment, resulting in relatively low inspection accuracy.

4. Electronic inspection method: Electronic inspection method can intuitively understand the welding process and welding quality, with relatively simple operation and low cost, but requires the use of instruments, resulting in relatively high inspection accuracy.

Selection of Weldability Welding Inspection Methods

The selection of weldability welding inspection methods should be based on the specific situation. Generally speaking, if the welding quality requirements are high, multiple inspection methods can be used to ensure the welding quality. If the welding quality requirements are low, physical or chemical inspection methods can be used for inspection.

The weldability welding inspection method is a very important part in the manufacturing process of electronic products. By using different inspection methods, you can fully understand the welding quality, timely find welding defect and problems, and ensure the quality and reliability of products. However, it should be noted that different inspection methods have their own advantages and disadvantages, and the inspection results may have errors and inaccuracies. Therefore, when conducting inspections, various factors should be comprehensively considered, appropriate inspection methods should be selected, and comprehensive judgments should be made to determine whether the welding quality meets the requirements.

In addition, in the manufacturing process of electronic products, weldability welding inspection is only a part of quality control, and it is also necessary to comprehensively consider product design, material selection, manufacturing process control, and other aspects to ensure product quality and reliability. Therefore, when conducting weldability welding inspection, multiple factors should be comprehensively considered to ensure the quality and reliability of the product.
