What is the composition of PCBA testing components?
ICT testing (online testing)
This section mainly includes testing of circuit switching, current value, voltage, amplitude, noise, etc., to check whether PCB manufacturing and assembly are normal.
FCT testing (functional testing)
Its purpose is to test the entire PCBA circuit board after IC program placement, check for code and hardware issues, and equip it with corresponding placement process fixtures and testing racks.
fatigue test
By analyzing the results of PCB manufacturing and assembly samples that have undergone this test, we can understand the functional operation of the PCB assembly board and determine whether there are any faulty areas. For example, if the mouse is clicked up to 100000 times or the LED is turned on and off 10000 times, the possibility of a malfunction is tested. Therefore, the above example can demonstrate that the performance of the PCBA board has been fully demonstrated through this test.
Testing in harsh environments
This includes testing circuit cards under extreme conditions such as temperature and humidity, drops, splashes, impacts, etc. Therefore, random samples can be obtained and the standard responsibility of the entire printed circuit component can be inferred.
Aging test
It mainly observes whether there is a fault intuitively by powering on the assembled circuit board and electronic products for a long time and maintaining their operating state. It is worth noting that only after this step of testing will it be put into the market and sold in factories.
The assembly and testing process of electronic circuit boards is quite complex and plays a crucial role in the entire production process. Without this process, products will experience high failures and rework, which is very detrimental to the development of enterprises. Through the assembly testing and assembly process of printed circuit boards, enterprises can timely understand the quality and effectiveness of their products, make timely improvements based on problems, ensure product reliability, and create a favorable environment for the development of the enterprise and the establishment of its brand.
