AOI is the short form of Automated Optical Inspection. It is an expensive but effective test for LED light PCBs.
During this test, the inspector uses a well-structured AOI machine to take 2D and 3D photographs of the circuit board. Then, an automated program compares these images with ideal LED circuit board images and finds out the loopholes of designs.
If the tested PCB design does not match to a certain degree, you need to change your design. You can apply the AOI test if you want to optimize your LED high-volume PCB projects.
AOI Test For LED PCB
FPT (Flying Probe Test) is another dependable test method. Here, the inspector involves electric probes from X, Y, Z-axis. These probes touch the LED bulb PCB surface and the inspector can see the results on the computer screen.
You can check the voltage, current, power ratings through the flying probe test. Its USP (Unique Selling Point) is that you don’t require additional features here.
Besides, electrical probes shift to the next board automatically. Though the FPT takes time, it is good for low-volume PCB manufacturing due to its cost-efficiency.
The Automated X-ray Inspection (AXI) test is usually used to detect dimensional defects of LED driver PCB or LED bulb PCB. X-ray helps to check some portions of PCB surface where traditional tests are not viable.
You can detect faults in soldering, back drill, conformal coatings, etc. This is also a costly inspection. So, you need to think of the AXI for large-scale PCB manufacturing.
Besides, it is essential to conduct peel tests, vibration tests, thermal tests, functional tests for LED circuit boards from time to time.
LED PCBs offer a wide variety in the case of the price range, durability, functionality, etc. Usually, standard LED bulb PCB boards costs vary from $100-$500 depending on their features and applications. The following factors their cost performance most-
