10 / 12 page [Data Sheet] [SML-M13x/MN2x 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℃ Tsmin Minimum of pre-heating temperature 140℃ ts Time from Tsmin to Tsmax Over 60sec. Reference temperature 230〜250℃ tL Retention time for TL Within 40sec. TP Peak temperature 250℃(Max) ΔTD/Δt Temperature decreasing rate Over -3℃/sec. TL b) Handling after soldering Please handle after the part temp. goes down to room temp. ※Above conditions are for reference. Therefore, evaluate by customer’s own circuit boards and reflow furnaces before using, because stress from circuit boards and temperature variations of reflow 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 furnaces vary by customer’s own conditions. Sn-Cu,Sn-Ag-Cu,Sn-Ag-Bi-Cu ②HAND SOLDERING CONDITION LED products do not contain reinforcement material such as a glass fillers. RECOMMENDED CONDITION Condition ) Temp. of iron top less than 325℃ within 3 sec. So thermal stress by soldering greatly influence its reliability. Please keep following points for manual soldering. ITEM a) Please follow the conditions below if the cleaning is necessary after soldering. Ultrasonic Cleaning 15W/Below 1 liter (capacity of tank) Drying Under 100℃ within 3 minutes Solvent We recommend to use alcohols solvent such as, isopropyl alcohols Temperature Under 30℃ within 3 minutes Heating method Heating on PCB pattern, not direct to the LED. (Fig-1) 4-8.Cleaning after Soldering tP Time for peak temperature Within 10sec. ΔTR/Δt Temperature rising rate Under 3℃/sec.
