5 for 24 hours. 3. soldering condition 3.1 pb-free solder temperature profile 3.2 reflow soldering should not be done more than two times. 3.3 when soldering, do not put stress on the leds during heating. 3.4 after soldering, do not warp the circuit board. lifecyclephase: revision : 1 expired period: forever release date:2008-09-20 00:16:12.0 everlight electronics co.,ltd. 27-21/bhc-ap1q2/3c everlight electronics co., ltd. http://www.everlight.com rev 1 page: 10 of 10 device no:szdse-271-b17 prepared date: 15-apr-2008 prepared by: xiao xiaoli 4. soldering iron each terminal is to go to the tip of soldering iron temperature less than 350 for 3 seconds within once in less than the soldering iron capacity 25w. leave two seconds and more intervals, and do soldering of each terminal. be careful because the damage of the product is often started at the time of the hand solder. 5.repairing repair should not be done after the leds have been soldered. when repairing is unavoidable, a double-head soldering iron should be used (as below figure). it should be confirmed beforehand whether the characteristics of the leds will or will not be damaged by repairing. everlight electronics co., ltd. tel: 886-2-2267-2000, 2267-9936 office: no 25, lane 76, sec 3, chung yang rd, fax: 886-2267-6244, 2267-6189, 2267-6306 tucheng, taipei 236, taiwan, r.o.c http://www.everlight.com |
