Regarding the Soldering operation
a. Use 25~ 30W soldering iron and maintain 310℃~330℃ in operation.
b. Operators who work in the solder fixture and the soldering iron must be statically grounded
under each soldering process.
c. Soldering should be accomplished within two seconds at each terminal so as not to be overheated.
d . Optimal design for heat sink pad is same as below.
