Notes for Mounting the Surface Mount Type Package
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).
