X-ray and Through/Blind-hole Drilling ings become more complex aer lamina- tion. Copper covers the top and bottom sur- faces, making it impossible for standard scan- ners to read through the copper. However, it is still possible to use an X-ray source to read a Figure 4: Data-matrix code read by X-ray on the inner layer. data-matrix code on an inner layer. From this, the machine can load the correct part program, locate fiducials, and link to the MES system. Following X-ray, should the process create a new code using a laser, via drilling, or through another method? If so, which code works Figure 5: Drilled data-matrix code by X-ray.
