LECO, BUEHLER AND STRUERS all have very good systems Of course for boards you will want to adapt them to your needs The one thing lacking in all is the ability to drill alignment holes to mount more than one sample at a time. If you can get your board shop to drill the holes during non-plated through hole operations you willhave an ideal situation. All systems rely on the centerline of holes to be examined to be on the same plane We have an Excellon Unidrill to drill the holes since we get so many different coupons and it also enables us to target holes in boards or other areas of interest in boards.
