Can you name several common soldering circuit board testing instruments? Let's reveal the answer. The ICT online tester, FCT operation testing, and aging testing constitute the equipment for PWB assembly testing.
1. ICT online tester
ICT has the advantages of wide application range and simple operation, and is highly praised. To achieve the purpose of detecting open circuits, short circuits, component damage, etc., it is indeed necessary to have the help of this effective testing method. In addition, it can accurately locate the fault location for easy maintenance.
2. FCT functional testing
Generally speaking, products that pass ICT testing can be transferred to functional testing. FCT functional testing mainly tests the corresponding functions of each product to determine whether the product is in good condition. More specifically, it refers to a testing method that provides a simulated operating environment for the testing target printed circuit board, allowing it to run in various design states and obtain parameters in each state to verify the functionality of the testing target printed circuit board.
3. Aging test
Aging testing generally simulates the external environment on the finished circuit board with assembled components. It simulates the daily use environment of the product through the comprehensive effects of high temperature, low temperature, high and low temperature changes, and electrical power. Defects in the assembly of the circuit board, such as poor soldering, inconsistent component parameters, and faults caused during debugging, are eliminated and improved to stabilize the parameters of the defect free PCB assembly board. PCBA boards that are consistent with electronic products are subjected to long-term simulation of consumer use for input/output testing to confirm their performance meets market demand.
These three types of testing instruments are common in the PWB assembly process. Our company Viasion attaches great importance to circuit board testing in the assembly and processing of circuit boards. Therefore, the customer has provided feedback that the PCB assembly we delivered fully meets the requirements. In addition, the repair rate of our products has also been greatly reduced.
