The warp and twist are required to be minimized as much as possible. z Reflow soldering is only applicable. z Be sure not to touch the component'

s (PT72) body by a soldering iron to avoid chipping. z The product side is not insulation construction. Avoid the pattern layout designing under/near the product. z If you use the product exceeding the max. working voltage, it may be a cause of the short mode failure. Mar. 2015 ........
