Why You Should Use X-Ray Fluorescent Testing
Posted on: 14 April 2020
Printed circuit boards (PCBs) are used in a variety of products, such as electronics and toys. For the PCBs to be effective, they need to be tested to ensure that they do not contain any defects. One of the testing methods often used for PCBs is X-ray fluorescence testing.
Advantages of X-Ray Fluorescent Testing
X-ray fluorescent testing is ideal when you have limited time to test your PCBs. It requires less capital and can allow you to increase production capacity. It is a non-destructive method, which is essential when testing products that will then be used in commercial goods.
A PCB is inspected at several points in the manufacturing process. The X-ray fluorescent test is performed at one of the stages in the manufacturing process. They measure the thickness of the coating and also perform a composition analysis when necessary in some models.
The Requirements of an X-Ray Fluorescent System
The type of X-ray fluorescent test used by the manufacturer must be able to test any section of the PCB. The larger the circuit board, the harder it will be for the device to be able to analyze the entire board. You will need to consider the depth of the slot. To meet most PCB requirements, you must analyze multiple spots on the board.
Properly Installing an X-Ray Fluorescent System
Before installing the X-ray fluorescent system, you'll want to consider all of the ways that you may want to use it. That way, you can install software to coincide with your X-ray fluorescent system that will help you perform the tests that you need to perform. Also, you'll want to make sure that you have all of the necessary filters installed and that everything is properly calibrated.
Choose an Analyzer with Many Options
Make sure to measure the size of the spots that will be tested with the X-ray fluorescent system. You might experience an error in measurement if you choose a collimator that is too large. The measurement spot should be about twice the size of the collimator. You will want to choose an analyzer that provides you with a broad range of options.
The X-ray fluorescent test has several advantages over the dispersive X-ray spectroscopy. It does not use an electron beam for excitation. The sample is also not as difficult to prepare because it does not require electrical conductivity. This allows insulators to be examined without a lot of effort.
