Procedures For Making Precision CH Bumps On Capsules
Recently we were asked to produce target capsules with bumps on the surface. The bumps were to test the effects of fill tubes in future targets. The bumps desired were to be Gaussian in shape and from 60 to 40 {micro}m in diameter and from 1 to 6 {micro}m high. The capsules had a nominal diameter of 500 {micro}m. The approach we used was to align a precision aperture to the capsule and coat through the aperture onto the capsule surface using plasma polymer coating. The bumps were characterized using optical microscopy, Wyko interferometry, and AFM sphere mapping.
