11 / 13 page [Data Sheet] Ultrasonic Cleaning 15W/Below 1 liter (capacity of tank) Drying Under 100℃ within 3 minutes furnaces vary by customer’s own conditions. So thermal stress by soldering greatly influence its reliability. Please keep following points for manual soldering. ITEM a) Heating method b) Handling after soldering Please handle after the part temp. goes down to room temp. Solvent We recommend to use alcohols solvent such as, isopropyl alcohols Temperature Under 30℃ within 3 minutes 4-8.Cleaning after Soldering Please follow the conditions below if the cleaning is necessary after soldering. RECOMMENDED CONDITION 400℃ within 3 sec. Heating on PCB pattern, not direct to the LED. (Fig-1) 4-7.Attention Points in Soldering Operation This product was developed as a surface mount LED especially suitable for reflow soldering. So reflow soldering is recommended. In case of implementing manual soldering, please take care of following points. ①SOLDER USED Sn-Cu,Sn-Ag-Cu,Sn-Ag-Bi-Cu ②HAND SOLDERING CONDITION LED products do not contain reinforcement material such as a glass fillers. Condition ) Temp. of iron top less than reflow furnaces before using, because stress from circuit boards and temperature variations of reflow tL Retention time for TL Within 40sec. TP Peak temperature 260℃(Max) tP Time for peak temperature Within 10sec. ΔTR/Δt Temperature rising rate Under 3℃/sec. ΔTD/Δt Temperature decreasing rate Over -3℃/sec. ※Above conditions are for reference. Therefore, evaluate by customer’s own circuit boards and Tsmin Minimum of pre-heating temperature 140℃ ts Time from Tsmin to Tsmax Over 60sec. TL Reference temperature 230〜260℃ [SML-E1x series] 4-6.Reflow Profile For reflow profile, please refer to the conditions below:(※) ■Meaning of marks, Conditions Mark Meanings Conditions Tsmax Maximum of pre-heating temperature 180℃ Fig-1 SOLDERING LAND SOLDERING IRON ________________________________________________________ www.rohm.com ©2016 ROHM Co., Ltd.
