What x-ray system do I need for my applications?
- The right system will depend on your specific application. However, the questions you should be asking your potential x-ray system supplier (using the requirements for a system for general printed circuit board assembly needs, or PCBA, that includes BGA and flip chip inspection as an example) should include, amongst others:
- Does the system have an open x-ray tube to give me the highest resolution and magnification, especially as devices and joints are continuing to shrink in size?
- Does the system tilt the detector instead of tilting the sample to achieve oblique angle views without compromising the available magnification?
- What is the maximum oblique angle view?
- Can less skilled operators use the system simply and easily without compromising the analytical quality?
- Does the system have collision-free sample movement?
- Does the system have a digital detector to provide the best image quality in real time?
- What is the greyscale sensitivity of the system?
- Can I automate my inspection procedures?
- Can I measure BGA void percentages and BGA solder ball diameters manually and automatically?
- Does what I need come as standard or what additional system options will I need to ensure that I have the facilities that I need?
- What is the price – including all the necessary options for my needs if not provided as standard!
