Commonly used PCBA function test equipment
When we perform functional tests on PCBA, such as ICT online tester, FCT functional test and burn-in test, we need some equipment. Several commonly used equipment for PCBA functional test are FCT automatic tester, ICT online tester, and burn-in test. Let's introduce the specific content below.

The FCT automatic tester is a test tool to test whether the PCBA is qualified; the FCT automatic test is divided into two parts (the main part and the test fixture part); the main part of the FCT automatic tester includes the computer system and the signal sampling system.

PCBA testing refers to the electrical continuity and testing based on input and output values of PCB boards that have undergone SMT chip processing, DIP plug-in processing and other processing links. PCBA testing is an important part of the manufacturing process and usually requires a lot of testing equipment. Common PCBA test equipment includes: ICT online tester, FCT function test and aging test.

1. ICT online tester. ICT is an automatic online tester with a wide range of applications and simple operation. The ICT automatic online detector is mainly for production process control, and can measure resistance, capacitance, inductance, and integrated circuits. It is particularly effective for detecting open circuit, short circuit, component damage, etc., with accurate fault location and convenient maintenance.

2. FCT function test. The FCT function test is to provide a simulated operating environment such as excitation and load to the PCBA board, which can obtain various state parameters of the board to detect whether the functional parameters of the board meet the design requirements. FCT function test items mainly include voltage, current, power, power factor, frequency, duty cycle, brightness and color, character recognition, voice recognition, temperature measurement, pressure measurement, motion control, FLASH and EEPROM burning, etc.

3. Aging test. The aging test refers to the process of simulating the various factors involved in the actual use of the product to carry out corresponding conditions to strengthen the experiment on the aging of the product. According to the electronic product PCBA board, a long-term power-on test can be carried out to simulate customer use and input/output tests to ensure that its performance meets market needs. These three kinds of test equipment are common in the PCBA process. The PCBA test is carried out in the PCBA processing link to ensure that the PCBA board delivered to the customer meets the customer's design requirements and greatly reduces the repair rate.

The above is the commonly used PCBA function test equipment carefully organized by the editor. If you want to know more PCBA knowledge or need PCBA SMT and THT plug-in processing services, please contact
