   * Decapping: always destructive for epoxy packages, I am equipped to get the die out but the package will be broken in the process thus the chip won't work; ceramic lidded packages should still work.
   * Imaging: I can image using any of the listed optics for you with 20x typically being the highest for a full die, plus you can specify ROIs to be imaged at higher magnification.
-  * Deprocessing: I can deprocess the die down to the substrate, **without** taking intermediate images -- you'll get top metal + substrate images only.
+  * Deprocessing: I can deprocess the die for simple dies with 1 metal layer so producing top metal/poly/substrate images. For dies with more than one metal layer, results will vary.
 The default package is, I do imaging top metal at 20x, decapping and/or deprocessing would obviously require more work and consume more material.

 If decapping is required, please bear in mind that it may result in damage/destruction of samples despite trying my best; providing multiple samples is highly desirable. Decapping different package types:
-  * Ceramic lidded packages is universally successful just by desoldering the lid.
