My thoughts include that you should consider:

1.      How to run DOE's and GR&R (or assume they come in with a back ground).

2.      How to run failure analysis  with multiple examples which include  techniques used and (why not used) as well as the thought process.

3.      Horror& risks of manual cleaning.

4.      Chemistry interactions with labels, ink markings

5.      Listing & review of useful IPC  (and other industry) specifications

6.      FOD - issues with identification, risk, control, etc.

7.      FTIR usefulness and complications.   (like statistics- you can almost never say you are certain - especially with unknown "crud").

8.      How clean does DI water really need to be

9.      Thoughts on steam cleaning

10.     When (if ever)  can you leave a residue on a PCA ( coating of residues).

11.     Lots of nasty looking failure pictures to scare the "bah-gee-bees" out of them

Good morning Technetians



OK, so I have been thinking (and we know how dangerous that is) about developing a course of study for someone to become a "cleaning expert".

Something along the lines of starting with a new hire and educating the new hires up to my level. Courses would include things like flux chemistry, cleaning processes and chemistry, cleanliness measurement methods, SIR methods, etc.  What items would you suggest be added to the course of study?
