I am presently working as an contractor for the next few months then back to unemployment, last place I worked was Jet Propulsion Laboratory on the Mars Science Laboratory.  These are lighted panels for various aircraft and the company policy is for J-STD-001/IPC-A-610 Class 3  The failure is with miniature T-1 lamps that stop working after going through an baking process.  Other boards that use these lamps but use RMA flux do not have this problem, I suspect the cleaning process and the flux.  They do not check ionic contamination and handle the boards with bare hands and the operators even know when components are ESD sensitive or not.  I have recommended they change the cleaning process to an Aqueous type batch cleaner but this cost money which they do not wish to spend.  Their process person believes that their process is fine and something else is causing the problem (bad lamps, forming lamp leads, etc.).  This goes against all my knowledge and training.
