SUPERWORLD ELECTRONICS (S) PTE LTD PG. 6 26.01.2015 FERRITE CHIP INDUCTORS L3 SERIES 8. SOLDERING AND MOUNTING : 8-1. Recommended PC Board Pattern 3.00 1.00 8-2.2 Soldering Iron : 8-2.1 Lead Free Solder Re-flow : cannot be avoided, the preferred technique is the utilization of hot air soldering tools. Mildly activated rosin fluxes are preferred. The terminations are suitable for re-flow soldering systems. If hand soldering Recommended temperature profiles for lead free re-flow soldering in Figure 1. (Refered to J-STD-020C) Products attachment with a soldering iron is discouraged due to the inherent process control limitations. If a a) Preheat circuit and products to 150° C. b) 350° C tip temperature for Ferrite chip bead (max) c) Never contact the ceramic with the iron tip soldering iron must be employed the following precautions are recommended. for Iron Soldering in Figure 2. Note : 8-2. Soldering e) Use a 20 watt soldering iron with tip diameter of 1.0mm f) Limit soldering time to 4-5 secs. d) 1.0mm tip diameter (max) mechanical stress when warping the board. PC board should be designed so that products can prevent damage from Preheating TP(260° C/40s max.) 60~180s 4 80s max. Figure 1. Re-flow Soldering:3 times max 150 25 200 217 Time(sec.) Within4 ~5s G rad ual Cooling O ve r 60s. Figure 2. Wave Soldering:1 times max cooling 60~150s 20~40s Soldering Natural cooling 150 350 Preheating Soldering Natural Re-flow soldering temperatures below 240 degrees, there will be non-wetting risk If wave soldering is used ,there will be some risk.
