Lead-Free Packaging
CAUTION: When ball grid array (BGA) packages with Sn-Ag-Cu balls are mounted using Sn-Pb eutectic
soldering, junction strength may be reduced under some conditions of use.
·
Storage of Semiconductor Devices
Because plastic chip packages are formed from plastic resins, exposure to natural environmental conditions
will cause absorption of moisture. During mounting, the application of heat to a package that has absorbed
moisture can cause surfaces to peel, reducing moisture resistance and causing packages to crack. To prevent,
do the following:
(1) Avoid exposure to rapid temperature changes, which cause moisture to condense inside the product.
Store products in locations where temperature changes are slight.
(2) Use dry boxes for product storage. Products should be stored below 70% relative humidity, and at
temperatures between 5°C and 30°C.
When you open Dry Package that recommends humidity 40% to 70% relative humidity.
(3) When necessary, FUJITSU SEMICONDUCTOR packages semiconductor devices in highly
moisture-resistant aluminum laminate bags, with a silica gel desiccant. Devices should be sealed in
their aluminum laminate bags for storage.
(4) Avoid storing packages where they are exposed to corrosive gases or high levels of dust.
·
Baking
Packages that have absorbed moisture may be de-moisturized by baking (heat drying). Follow the FUJITSU
SEMICONDUCTOR recommended conditions for baking.
Condition: 125°C/24 h
·
Static Electricity
Because semiconductor devices are particularly susceptible to damage by static electricity, you must take
the following precautions:
(1) Maintain relative humidity in the working environment between 40% and 70%. Use of an apparatus
for ion generation may be needed to remove electricity.
(2) Electrically ground all conveyors, solder vessels, soldering irons and peripheral equipment.
(3) Eliminate static body electricity by the use of rings or bracelets connected to ground through high
resistance (on the level of 1 M).
Wearing of conductive clothing and shoes, use of conductive floor mats and other measures to
minimize shock loads is recommended.
(4) Ground all fixtures and instruments, or protect with anti-static measures.
(5) Avoid the use of styrofoam or other highly static-prone materials for storage of completed board
assemblies.
