I sent this out last week but I believe it didn't get through so I'm
trying again.


I would appreciate some help here from you guy's & gal's!

On considering the switch from using RMA flux for Class 3 to OA-(WS) for
board assembly a full SIR testing exercise has been carried out
externally IAW IPC-TM-650 using appropriate test coupons; this proved
satisfactory.

ROSE testing will be used locally as a form of process control but I was
wondering whether their would be benefit in using ion chromatography to
assess the first off's pucker hardware...........maybe one for you Doug!
