About solder ability, following conditions were confirmed
(1) Solder ability
(1) Use of Sn-37Pb solder Bath
• solder bath temperature = 230°C
• dipping time = 5 seconds
• the number of times = once
• use of R-type flux
(2) Use of Sn-3.0Ag-0.5Cu solder Bath
• solder bath temperature = 245°C
• dipping time = 5 seconds
• the number of times = once
• use of R-type flux
This product has a MOS structure and is sensitive to electrostatic discharge. When handling this product, ensure
that the environment is protected against electrostatic discharge by using an earth strap, a conductive mat and an
ionizer. Ensure also that the ambient temperature and relative humidity are maintained at reasonable levels.
