(5) Handling Precautions
· Warpage of circuit board with soldered LEDs may result in damage or package breakage of the LEDs.
· Depending on the position and direction of LED, the mechanical stress on the LED package can be
· When separating the circuit boards with soldered LEDs, please use appropriate tools and equipment.
· Bare Hand
· Tweezers
Please pay special attention to the orientation of the LEDs as to avoid LED failure caused by bow, twist
and warpage of the board.
changed. Refer to the following figure.
Hand brake without these tools and equipment may not be used.
When handling the product, touching encapsulant with bare hands will contaminate its
surface that could affects on optical characteristics.
force to the encapsulant by hands might result in catastrophic failure of the LEDs due to
wire deformation and/or breakage.
Since silicone used as encapsulating resin in this product is a soft material, the upper surface of the
product is soft.
