As for <a href=\"https:\/\/www.bestpcbs.com\/\">PCB<\/a> inspection, X-ray is commonly used in the inspection of <a href=\"https:\/\/www.bestpcbs.com\/products\/pcba.htm\">PCB assembly<\/a> in order to test the quality and find the hidden defects, X-ray inspection is one of the most important steps for quality-oriented <a href=\"https:\/\/www.bestpcbs.com\/\">PCB<\/a> manufacturers.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><a href=\"https:\/\/www.bestpcbs.com\/blogimages\/2022\/6\/15\/X-Ray-Machine.jpg\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blogimages\/2022\/6\/15\/X-Ray-Machine-s.jpg\" alt=\"\"\/><\/a><figcaption>X-Ray Machine<\/figcaption><\/figure><\/div>\n\n\n<p><strong>X-Ray Inspection\u2019s Working Principle<\/strong><\/p>\n\n\n\n<p>Generally, there are three elements in the X-ray devices.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>X-ray tube\u2014to generate the X-ray photons.<\/li><li>Operation platform\u2014to move along with the sample so that the sample can be inspected from different angles and magnification.<\/li><li>Detector\u2014it can capture the X-ray through the samples and then transfer it into the image so that we can find out whether there are defects on the<a href=\"https:\/\/www.bestpcbs.com\/\"> printed circuit board<\/a>.<\/li><\/ul>\n\n\n\n<p><strong>The Hidden Defects that can be Identified by X-Ray<\/strong><\/p>\n\n\n\n<p>Since <a href=\"https:\/\/www.bestpcbs.com\/\">PCB<\/a> has the higher density with the solder joints hidden and holes buried or blind, X-ray enable us to inspect the quality of the <a href=\"https:\/\/www.bestpcbs.com\/\">PCB<\/a> and identify various hidden defects. And there are three common hidden defects that can be inspected by X-ray.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><a href=\"https:\/\/www.bestpcbs.com\/blogimages\/2022\/6\/15\/PCB's-Image-After-X-Ray.jpg\"><img decoding=\"async\" src=\"https:\/\/www.bestpcbs.com\/blogimages\/2022\/6\/15\/PCB's-Image-After-X-Ray-s.jpg\" alt=\"\"\/><\/a><figcaption>PCB&#8217;s Image Under X-Ray<\/figcaption><\/figure><\/div>\n\n\n<ul class=\"wp-block-list\"><li>Solder bridges\u2014it is a common issue that will occur when the solder joints are so close that they create a connection which is not allowed. And usually, the solder bridges will be covered by some components on the <a href=\"https:\/\/www.bestpcbs.com\/\">PCB<\/a>. But they can be easily found with the help of the X-ray device.<\/li><li>Solder voids\u2014when gas or flux is entrained during welding, solder voids will be produced, which will lower the thermal conductivity at the solder joint and may cause physical defects. And X-ray can help to &nbsp;identify the solder voids<\/li><li>Pin-hole fills\u2014pin-hole fills issue is a common problem occurring in the plug-in components on the &nbsp;<a href=\"https:\/\/www.bestpcbs.com\/\">printed circuit boards<\/a>. The X-ray device can be used to identify these errors, and can even quantify the missing filling amount.<\/li><\/ul>\n\n\n\n<p><strong>Our X-Ray Inspection Device<\/strong><\/p>\n\n\n\n<p>The maximum size of the board that can be put in the device\u2019s operation platform is 510*430 mm, while the maximum inspection size of the device is 435*385 mm. So here is the manifestation of the operation platform\u2019s function. When the size of <a href=\"https:\/\/www.bestpcbs.com\/\">PCB<\/a> is over 435*385 mm, the operation platform will move along with the board so that the board can be inspected thoroughly.<\/p>\n\n\n\n<p>And here is a video about operation of our X-ray inspection device.<\/p>\n\n\n\n<figure class=\"wp-block-video aligncenter\"><video controls src=\"https:\/\/www.bestpcbs.com\/blog\/wp-content\/uploads\/2022\/06\/123-1.mp4\"><\/video><\/figure>\n\n\n\n<p>So, this is the end of this article.
