Thermal analysis is a technical method to measure and analyze the relationship between material thermodynamic parameters or physical parameters and temperature. The so-called thermal analysis refers to the analysis of the change of the corresponding physical and chemical properties of the sample by controlling the change of its temperature. According to the induction and classification of the International Association for Thermal Analysis (ICTA), the current thermal analysis methods are divided into nine categories and seventeen kinds, while at present we commonly use five kinds, namely: differential scanning calorimetry (DSC), thermogravimetry (TG), thermal differential analysis (DTA), thermomechanical analysis (TMA), dynamic thermomechanical analysis (DMA) and other five methods. The following article will briefly introduce thermal analysis. Let's have a look! View >>

When producing electronic products, we need to pay attention not only to the production process, but also to the product defects, especially the defect detection, which can mainly detect the defects on the product surface, and can use advanced detection technology. Generally, when we check the soldering quality of BGA solder ball, if it is a defect in bridging/short circuit, it can be detected by using X-Ray equipment; However, it is more complicated to check whether the solder ball has empty soldering or cracks.

X-Ray detection is a kind of low-energy X-ray that can quickly detect the internal quality of the detected object and the internal quality of the foreign object and the foreign object, and display the image of the detected object through the computer. X-ray is an electromagnetic wave with wave length and wavelength range of 0. 0006-80nm. This kind of electromagnetic wave has strong penetration ability, can penetrate materials with different densities, and also has good penetration to some objects that cannot be penetrated by visible light.

Halogen test, halogen-free test and HF test all mean halogen test. Halogen compounds are widely used in the electronic industry. For example, chlorinated paraffin can be used as a plasticizer for plastic materials, and difluorodichloromethane can be used as a foaming agent in ABS, PS, PVC, PU and other plastics. However, halogen compounds are widely used as flame retardants. Common halogen flame retardants include bromine flame retardants such as PBB, PBDE, TBBP-A and HBCDD, and chlorine flame retardants such as short-chain chlorinated paraffin and PCB.

In the processing of electronic products, there may be obvious defects and potential defects. Aging test is a test method designed to test the reliability and service life of products. It mainly tests the durability and reliability of products by exposing them to a simulated environment and simulating the effects of temperature, humidity, voltage and other conditions that often occur in the process of use.

The welding of BGA is an important process of pcba processing. Due to improper PCB design, the problem of bad BGA welding is often encountered. At this time, X-ray fluoroscopy can ensure the reliability of welding connection. So it is very important to diagnose the bad soldering of BGA during reflow soldering of pcba processing. In order to help you understand in depth, this paper will summarize the relevant knowledge of bad BGA welding. If you are interested in the content to be covered in this article, please read on.

Non-destructive testing is an indispensable and effective tool for industrial development, which to some extent reflects the level of industrial development of a country, and its importance has been recognized. It is the general name of all technical means to detect whether there are defects or nonuniformities in the inspected object by using the acoustic, optical, magnetic and electrical characteristics without damaging or affecting the service performance of the inspected object, give the size, location, nature and quantity of the defects, and then determine the technical status of the inspected object (such as qualified or not, residual life, etc.).

The so-called third-party testing industry acts as an intermediary. It is mainly an organization that participates in the inspection and testing as a fair non-party. For the third party inspection industry, there are inspection equipment industry, manufacturers of industrial and consumer products with terminals, and midstream third party inspection institutions, which evaluate the quality and performance of products with scientific methods and professional equipment and issue relevant reports by accepting the entrustment of customers.
