Products are packaged using silicone, environmentally friendly lead-free process product requirements. Light-emitting diode chip material gallium nitride. 2, high brightness, light color consistency; 3, LED Chip Life: "50,000 hours; 4, the use of high-quality silicone glue package imported from Japan, bad low light, long life; 5, the use of imported chips formal qualification, United States and Britain US special phosphor, quality assurance; 6, quality assurance, reasonable price, have regular inventory, delivery is very timely. Note: a) material no more than 2 times the number of welds. Suitable for all SMT assembly and soldering processes. b) Do not twist welding temperature back down to normal after the circuit board. Second, the manual welding specifications: hand soldering iron temperature no higher than 300 ℃, each solder tail welding time is not more than three seconds three storage specification: 1. In the Not Ready Do not open the bag before using antistatic LED. 2. LED Before unopened should be stored below 30 ℃, humidity 60% or less of the environment, the longest shelf life of one year. 3. Open the package until after, LED should be kept at 30 ℃ / 40% humidity under the following conditions, and must be finished within 7 days use. 4. If the LED is beyond the requirements of point 3, the LED must go through in order to use baking, baking conditions: 60 ± 5 ℃, 12 hours. Four: Product Description: 1. Product dehumidification: SMD product due to moisture absorption after welding at high temperatures can cause water vapor evaporation and expansion, likely to cause interfacial peeling, chip and support the gold wire connected to pull off, so customers before using unpacking 65-70 degrees with baking reuse more than 12 hours after opening the package to be welded complete in the fastest time, not more than 24 hours, such as more than 24 hours, we need to do dehumidifying again. (Reel loaded baked: 65-75 degrees / 10- 15H bulk Baking: 130-150 degrees / 2-3 hours) 2.SMT patch: customers in the SMT placement need to select a ratio SMD (colloid) large light-emitting surface nozzle to prevent pressure nozzle height setting improper internal lamp beads gold wire is damaged or SMT nozzle under pressure can also affect the height of the lamp beads quality, because too deep under the oppression of the nozzle pressure lamp beads Colloidal gold wire lead to internal deformation or fracture, causing the lamp is not lit or blinking beads and quality problems, select the appropriate nozzle is to provide quality products of the key technology lies. 3. Manual Welding: We recommend using heated iron and selection of <0.5mm solder wire, and the temperature was controlled within degree, a single lamp bead welding time can not be more than three seconds, the welding process due to the colloidal state at high temperatures, do not press the colloid surface can not be applied to the LED pin pressure to melt tin and lead wire binding nature, careful not to use a hard object and objects with sharp edges scraping, paint, pressure colloid surface, easily lead to gold wire deformation inside the stent. Cause dead lights. (Mass production can not hand soldering, hand soldering quality because of instability) 4. Reflow soldering: SMT chip production required mass production, we recommend that the melting point of the solder paste used in the following 220 degrees, preferably eight reflux temperature zones welding, the maximum temperature should not exceed 240 degrees, the peak time of less than 10S, reflow need a complete, not too light beads twice over reflow, multiple reflow damaging the product. Lamp beads should repair after reflow, when repair is unavoidable, you must use the heating units or welding Confirmed operation, but must be confirmed in this way may or may not damage the LED own characteristics. 5. vulcanization measures: After due SMD lamp beads soft silicone products are not anti-curing, LED curing if there will affect the brightness products, light color shift, the bottom bracket black and other undesirable phenomena, so the use of SMD products in the process must take anti- curing measures. In the production process, you can not use sulfur-containing solder paste, washer water. Because there will be PCB chemical plant residual volume in the production process, and therefore need to be used before the PCB 70 degrees with dehumidification bake 3-6 hours, residual volatile material. Processed semi-finished products, avoid light beads containing sulfur compounds and materials in contact, such as those containing sulphides boxes, bubble bags, rubber bands. 6. Anti-static measures: use in contact with the product machine grounding wire required, please use an electrically conductive workbench pad through a resistor to ground, the tip of the soldering iron table must be grounded, the operator should wear a wrist strap, static clothing and so on, it is recommended from the electronic generator. 7. Product testing: Our products shipped, customers do incoming inspection, there are problems and timely feedback, before mass production use, make small series production, confirmed that no problem and then mass production, hand-picked no more than 10% of the total volume.
