SOT-223 SOLDERING RECOMMENDATIONS
It is not recommended to use hand soldering or wave sol-
dering to attach the small SOT-223 package to a printed
circuit board. The excessive temperatures involved may
cause package cracking.
Either vapor phase or infrared reflow techniques are pre-
ferred soldering attachment methods for the SOT-223
package.
