Notes for Mounting the Surface Mount Type Packages

The surface mount type packages are very susceptible to heat in reflow mounting and humidity

absorbed in storage.

Therefore, before you perform reflow mounting, contact Oki’s responsible sales person for the product

name, package name, pin number, package code and desired mounting conditions (reflow method,

temperature and times).
