The device has been qualified to meet the JEDEC  
standard for Pb-Free assembly. The temperatures  
and time intervals listed are based on the Pb-Free  
small body requirements. The temperatures refer to  
the topside of the package, measured on the  
package body surface. The CD-700 device is  
hermetically sealed so an aqueous wash is not an  
issue.
