  1. Soldering Profile (1) Reflow Soldering Conditions / Profile (Lead Free Solder) (2) Hand Soldering conditions Do not exceed 4 seconds at maximum 315ºC under soldering iron. (3) The encapsulated material of the LEDs is silicone. Precautions should be taken to avoid the strong pressure on the encapsulated part. So when using t he chip mounter, the picking up nozzle that does not af fect the silicon e resign should be used. Note : In case that the soldered products are reused in soldering process, we don’t guarantee the products.

  1. Precaution for use (1) Storage In order to avoid the absorption of moisture, it is recommended to store in a dry box (or a desiccator) with a desiccant. Otherwise, to store them in the following environment is recommended. Temperature : 5ºC ~30ºC Humidity : maximum 70%RH (2) Attention after open. LED is c orrespond to SMD, whe n L ED be solde red di p, interfacial se paration m ay affect the light transmission efficiency, causing the light intensity to drop. Attention in followed; Keeping of a fraction Temperature : 5 ~ 40ºC Humidity : less than 10% (3) In the cas e of m ore tha n 1 week pa ssed after opening o r change col or of indicator on desi ccant, components shall be dried 10-12hr. at 60¡¾5ºC. (4) Any mechanical force or any excess vibration shall not be accepted to apply during cooling process to normal temperature after soldering. (5) Quick cooling shall be avoided. (6) Components shall not be mounted on warped direction of PCB. (7) Anti radioactive ray design is not considered for the products. (8) T his de vice sh ould not be use d i n a ny type of fl uid s uch as water, oil, o rganic s olvent et c. When washing is required, IPA should be used. (9) When the LEDs are illumin ating, operating current should be decided after con sidering the ambient maximum temperature. (10) The LEDs must be soldered within seven days after opening the moisture-proof packing. (11) Repack unused products with anti-moisture packing, fold to close any opening and then store in a dry place. (12) The appearance and specifications of the product may be modified for improvement without notice.

  1. Handling of Silicone Resin LEDs (1) During processing, mechanical stress on the surface should be minimized as much as possible. Sharp objects of all types should not be used to pierce the sealing compound. (2) In general, LEDs should only be handled from the side. By the way, this also applies to LEDs without a silicone sealant, since the surface can also become scratched. (3) When populating boards in SMT production, there are basically no restrictions regarding the form of the pick and place nozzle, except that mechanical pressure on the surface of the resin must be prevented. This is assured by choosing a pick and place nozzle which is larger than the LED’s reflector area. (4) Silicone differs from materials conventionally used for the manufacturing of LEDs. These conditions must be considered during the handling of such devices. Compared to standard encapsulants, silicone is generally softer, and the surface is more likely to attract dust. As mentioned previously, the increased sensitivity to dust requires special care during processing. In cases where a minimal level of dirt and dust particles cannot be guaranteed, a suitable cleaning solution must be applied to the surface after the soldering of components. (5) SSC suggests using isopropyl alcohol for cleaning. In case other solvents are used, it must be assured that these solvents do not dissolve the package or resin. Ultrasonic cleaning is not recommended. Ultrasonic cleaning may cause damage to the LED.
