What is a PCBA tester？

Definition

PCB tester is specialized for printed circuit board components (Infrared Infrared PCBA) for testing professional equipment. It is like a rigorous quality inspector, before the PCBA enters the next production link or the final product, a comprehensive "physical examination". Its purpose is to accurately determine whether the performance indicators of PCBA fit the established design standards, so as to ensure the quality of electronic products.

Main types of tests

Circuit Connectivity Test: This test focuses on the conduction condition of the line on the PCBA. By inputting a small current signal into a specific circuit node, and then detecting the signal reception of other nodes, it can determine whether the circuit is open or short. For example, in the multi-layer circuit board, it can accurately find out the circuit blockage caused by the production process problem of the inner circuit.

Component parameter test: For PCBA on the dazzling array of electronic components, such as resistance, capacitance, inductance, etc., the tester can accurately measure its parameter values. For example, the capacitance of capacitors, the resistance of resistors, and the inductance of inductors, etc., ensure that the actual parameters of these components are within the tolerances allowed by the design. Once a component parameter deviation is too large, it may cause abnormal performance of the whole circuit, such as frequency drift, signal attenuation and other problems.

The function and significance of PCBA tester

In the electronic manufacturing industry chain, PCBA tester plays a pivotal role. It can find defects and faults of PCBA in the production process in time, avoid defective products flowing into the subsequent processes, so as to greatly reduce production costs and improve production efficiency. From the perspective of product quality, it is the key line of defense to ensure the reliability and stability of electronic products, reduce the product failure and repair rate caused by PCBA problems, and improve the brand image and user satisfaction.
