       Instructions for use 1. wash LED in order to prevent damage, do not use chemical cleaning liquids with no detail LED. When it is necessary to wash, dip in alcohol LED at room temperature, and no more than 1 minute, and then to dry at room temperature for 15 minutes then normally used. 2. moisture-proof packaging In order to prevent the transportation and storage of moisture intrusion to SMD LED,SMD LED in the process must be packed in sachets sealed. When packaging desiccant and humidity cards inside. Humidity humidity display on the card can provide moisture levels within the package. 3. storage Original packaging unopened storage environment: temperature < 40  humidity and stored under the <90% environment for no more than 12 months, when stored for more than 12 months under the roast has to be replaced. Before unpacking check that the packaging is leakage condition. After the package is opened, SMD LED products to be stored in a temperature < <60% 30 c and humidity environment, and SMD LED products in this environment must be opened within 24 hours after the package is finished (reflow soldering), if used for longer than the 24-hour baking again after use. Referred to above in the SMD LED is the baking in the oven at a temperature of 80 ± 5  relative humidity conditions <=10% for 24 hours. Bake again to remove the material from the package baked in the oven, baking process do not frequently open the oven door. 4. welding Manually with a soldering iron welding Welding chromium plated iron that is recommended when less than 25W, soldering iron temperature when welding products should remain at 315 below and must be completed within 3 seconds of welding. Welding tip not to touch the SMD LED epoxy resin part. Do not weld any mechanical pressure is applied on top of epoxy resin. Welding products when you are finished, only when temperatures drop below 40 c only when further processing is allowed, this is to prevent product failure due to mechanical thermal pressure of the follow-up. 5. electrostatic discharge and surge current Electrostatic discharge (ESD) and impact (EOS) may damage the SMD LED products. When there is no any protective measures to be taken when touching the SMD LED products are: ESD ESD wrist strap, ESD foot straps or ESD gloves. All replacement parts, equipment and machinery safety. Recommended in the test arrangement tests to pick out the bad products ESD. Circuits setting elimination of those to be sure current is very important. 6. heat treatment At design stage of SMD LED, SMD LED thermal management must be taken into account, according to SMD LED specifications included in the current changes with the temperature curve, the current should be appropriate in addition to low.
