The core of electronic equipment is the circuit board, which is welded and assembled by various types of electronic components. If the equipment fails or has a short circuit, most of the reasons will be caused by the failure or damage of electronic components. Next, the third-party testing organization will introduce you to the fault judgment and testing methods of circuit board components. You may wish to continue reading. View >>

First, what is aging test? During the aging test, the components on the special aging circuit board will bear the pressure equal to or higher than its rated working conditions to eliminate any components that fail prematurely before the rated life. These test conditions include temperature, voltage / current, operating frequency or any other test conditions specified as the upper limit. These types of stress tests are sometimes referred to as accelerated life tests (a subset of halt / HASS) because they simulate the operation of components under extreme conditions for a long time.

What is UV testing? UV test, also known as UV aging test, is a process of simulating various factors involved in the actual use conditions of products and strengthening the experiment of corresponding conditions. It can reproduce the damage caused by sunlight, rain and dew and obtain the service life of products in a short time. The equipment carries out the test by exposing the material to be tested to the controlled interactive cycle of sunlight and moisture and increasing the temperature at the same time. View >>

Nondestructive testing is to use the acoustic, optical, magnetic and electrical characteristics of materials to detect whether there are defects or non-uniformity in the tested object without damaging or affecting the service performance of the tested object, and give information such as the size, location, nature and quantity of defects. With the continuous improvement of testing requirements, nondestructive testing technology has widely adopted digital technology and has gradually entered the measurement field. For example, for the measurement of geometric quantities and material characteristic parameters, it is necessary to monitor and control the continuous stability of instrument indexes according to certain procedures, so as to improve the reliability of testing results.

Low temperature test is mainly used to evaluate the impact of low temperature conditions on the safety, integrity and performance of equipment during storage, work and disassembly. To determine the sequence of low temperature test, two principles should be followed: maximize the service life of equipment and the applied environment should be able to display the superposition effect to the greatest extent.

Ultrasonic testing, also known as ultrasonic testing and ultrasonic flaw detection, is a kind of nondestructive testing. Nondestructive testing is a testing method to check the surface and internal quality of the inspected parts without damaging the working state of the workpiece or raw materials. Ultrasonic nondestructive testing (NDI) is a development and application of ultrasonic nondestructive testing. Its equipment includes: ultrasonic flaw detector, probe, coupling agent and standard test block. Its purpose is to detect casting shrinkage cavity, bubble, welding crack, slag inclusion, incomplete fusion, incomplete penetration and other defects and thickness measurement. View >>

Chemical analysis is classified into classical gravimetric analysis and volumetric analysis. Gravimetric analysis refers to the calculation of the chemical composition of the sample according to the mass of the product generated by the chemical experimental reaction of the sample. Most of them refer to the mass method. Volumetric method refers to the volume of standard test solution consumed by the sample in the reaction. The volumetric method can determine the main components of the sample and the secondary components of the sample. View >>

Alternating damp heat test includes constant damp heat test and alternating damp heat test. The test simulates the environment of tropical rain forest to determine the adaptability of products and materials to use and storage when temperature changes and product surface condensation. It is commonly used in life test, evaluation test and comprehensive test. The technical indexes include: temperature, relative humidity, conversion time and alternating times. View >>
