Stress strength according to
he mounting position:
so please pay attention to the touch on product.
We recommend the soldering pattern that shows on the right.
It will be different according to mounting situation of circuit board,
therefore, please concern before designing.
・No resin hardening agent such as filler is used in the sealing resin of the product. Therefore, resin
expansion and moisture absorption at humidity will cause heat stress during soldering process and
・Compare with N2 reflow, during air reflow, because of the heat and surrounding conditions,
or damage of LED internal junction, therefore, please concern the mounting direction and position
to avoid bending or screwing with great stress of the circuit board.
the mounter to control the product stabilization. In addition, it is recommended to set ionizer
one of its specific characteristics is that solder will penetrate into LED. Thus, there's high possibility
that will influence its reliability.Therefore, please be informed, concerning it before using it.
４－２. Automatic Mounting
４-２-１. Silicon Resin Sealing Product
The sealing resin of LED is very soft, so please select adsorption nozzle that would not apply stress
directly on the sealing section.
４-２-２. Mini Package (Smaller than 1608 size)
・Vibration may result in low mounting rate since it will cause the static electricity of product and
adhere to top cover tape. Therefore, the magnet should be set on parts feeder cassette of
・Do not expose the product in the environment of high temperature (over 100℃) or rapid temperature
to prevent electrostatic charge.
４－３. Mounting Location
The stress like bending stress of circuit board dividing after mounting, may cause LED package crack
it may cause the discoloration of the resin.
・For our product that has no solder resist, because of its solder amount and soldering conditions,
finally has bad influence on the product’s reliability.
・The product is not guaranteed for flow soldering.
In case of carrying out flow soldering of surrounding parts without recommended conditions, please
contact us for inquiries.
・Please set appropriate reflow temperature based on our product usage conditions and specification.
・The max for reflowing is 2 times, please finish the second reflow soldering and flow soldering
with other parts within the usage limitation after open the moistureproof package.
shift (within 3℃/sec. of temperature gradient) during the flow soldering of surrounding parts.
４―４. Mechanical Stress after Mounting
The mechanical stress may damage the LED after Circuit Mounting,
