Generally speaking, the failure of integrated circuits is inevitable in the process of development, production and use. With the continuous improvement of people's requirements for product quality and reliability, failure analysis is becoming more and more important. Chip failure analysis can help integrated circuit designers find design defects, mismatch of process parameters or improper design and operation. The common methods of chip failure analysis are no more than those processes. The most important thing is to rely on various advanced and accurate electronic instruments. The following contents are mainly elaborated from these two aspects, hoping to be helpful to you. View >>

The transformer can be tested with a multimeter. As shown in the figure, the first is to detect the on-off of the winding coil, the second is to detect the insulation resistance between the winding coils, and the third is to detect the insulation resistance between the winding coil and the iron core.

Failure analysis is an important part of chip testing. Whether for mass-produced samples, design links or customer returned products, failure analysis can help reduce costs and shorten the cycle. Common failure analysis methods include decap, X-ray, IV, Emmi, FIB, SEM, EDX, probe, OM, RIE, etc. because failure analysis equipment is expensive, most demand units can not match or complete the required equipment. Therefore, it is also a good choice to use external forces and open resources to complete their own analysis. What information do we need to prepare when we choose to test outside? Let's sort it out for you: View >>

The ability or possibility of the product to perform the specified function without failure under certain time or conditions. The reliability of products can be evaluated by reliability, failure rate and mean time between failures. Moreover, this is an important quality index. Only qualitative description is not enough. It must be quantified in order to make accurate description and comparison. View >>

Reliability test is a means to investigate, analyze and evaluate the reliability of products. The test results provide a basis for fault analysis, study the corrective measures taken and judge whether the product meets the index requirements. According to the method and purpose of reliability statistical test, reliability statistical test can be divided into reliability verification test and reliability measurement test. Reliability measurement test is a test for measuring reliability characteristics or their values, which is usually used to provide reliability data. Reliability verification test is used to verify whether the reliability characteristic value of equipment meets the specified reliability requirements. Generally, reliability identification and acceptance test are collectively referred to as reliability verification test. View >>
