Note: 1.Temperature profiles show the temperature of PC board surface..please perform soldering test with your actual PC board before mass production, since the temperatures of PC board surfaces vary according to the size of PC board, status of parts mounting and heating method. PRECAUTIONS - For details on general precautions, refer to the section on technical descriptions. - Since this is a polarized relay, follow the instructions of the internal wiring diagram for the ± connections of the coil. - Note that the terminal layout and internal wiring of the surface mount relay are a top view 11
RoHS Compliance and Lead Free Relay Information 1. General Information If applicable, relays produced after the specific date code that is indicated on each data sheet are lead-free now. All of our signal and power relays are lead-free. Please refer to Lead-Free Status Info. (http://www.fujitsu.com/us/downloads/micro/fcai/relays/lead-free-letter.pdf) Lead free solder plating currently used in relays is Sn-3.Ag-.5Cu. From February 5 forward Sn-3.Cu-Ni will be used for the FTR-B3 and FTR-B4 series relays. All signal and power relays also comply with RoHS. Please refer to individual data sheets. Relays that are RoHS compliant do not contain the 5 hazardous materials that are restricted by RoHS directive (lead, mercury, chromium IV, PBB, PBDE, decabde and PFOS). It has been verified that using lead-free relays in leaded assembly process will not cause any problems (compatible). LF is marked on each outer and inner carton. (No marking on individual relays). To avoid lead containing relays (for lead-free sample, etc.) please consult with area sales office. We will ship lead containing relays as long as the lead containing relay inventory exists, if allowed. Note: Cadmium was exempted from RoHS on October 1, 5. (Amendment to Directive /95/EC). Recommended Lead Free Solder Profile Recommended solder paste Sn-3.Ag-.5Cu or Sn-3. Cu-Ni (only FTR-B3 and FTR-B4 from February 5. Reflow Solder condition Flow Solder condition: Peak Temp.: max. 5 C Pre-heating: maximum 1 C Soldering Soldering: dip within 5 sec. at 5 6 C solder bath temperature ( C) 17 13 Pre-heating Cooling Solder by Soldering Iron: Soldering Iron Temperature: maximum 36 C Duration: maximum 3 sec. 9~1 sec. ~3 sec. max. 1 sec. (duration) 3. Moisture Sensitivity Moisture Sensitivity Level is not applicable to electromechanical relays. 4. Tin Whisker We highly recommend that you confirm your actual solder conditions SnAgCu and SnCuNi solder are known as low risk of tin whisker. No considerable whisker length was found by our in-house test. 1
