what is Board X-ray Testing ?

Intended for heavy output environments, X-ray is utilized to inspect uncooked PCBs and assembled PCBs containing advanced elements this sort of as BGAs, uBGAs and Flip Chips. This multipurpose procedure functions patented, award-winning X-ray digital camera technology that generates high-resolution, high-sensitivity visuals, revealing flaws as little as 0.001 inches which has a total one-inch diameter subject of look at. X-ray inspection is often paired with the electrical screening furnished by ICT or practical take a look at. It can be a super low-cost alternative for verifying prototypes as well as complex boards in quantity manufacturing.

The x-ray machine‘s high repeatability accuracy serves to boost production. The unique angle for sample inspection also makes it suitable for mass testing.

Automatic X-ray inspection relies on the exact same basic ideas as AOI, but instead of working with normal noticeable mild to examine the skin of the PCB, X-ray inspection can discover faults that could normally be hidden from watch. The X-ray inspection machine produces images of your PCB which are then analyzed by impression processing software program, which might detect abnormalities and also the presence or absence of characteristics like parts or wiring. This is certainly specially essential since it indicates that X-ray screening finds faults that AOI cannot. If carried out throughout the production course of action, this can help save a substantial degree of methods as it immediately stops defective pieces from losing any even more time during assembly.

X-ray tests is helpful not merely for the duration of manufacturing, but for the duration of rework. As part of the normal remodeling and repair service approach, engineers scan returned PCBs making use of the X-ray screening device to proficiently figure out the faulty link or element resulting in the PCB to fall short. This could certainly usually be performed promptly for the reason that X-ray inspection equipment may be geared either for low- to medium-volume production operates, or even the inspection of just some damaged PCBs. The remodeling method is as a result held as brief as is possible, much shorter than it might be in which our engineers to rely upon common visible inspection.
