SPC / Control Charts etc | 10 May, 2002

Morning guys,

I would just like to find out which type of control charts / SPC type methods (if any) that people are using for SM and flow soldering.

I am setting up process controls for our 3 flow solder machines at my new company and would just like to bounce some ideas around.

Regards & thanks,

Chris May

We chart the following: * Reflow: Time over liquidous +25�C * Wave: Contact time and track tin, copper, gold, and antimony in pot analysis.
