(2) High temperature solder reflow : For Sn96.5% , Ag3.5% , Cu0.5% alloy . (1) Lead wires should be soldered within

3 seconds with the iron heated to a temperature of 380°C ( max. ) . (2) In solder-dip mounting , it should be within

10 seconds with a temperature of 260°C ( max. ) . Suggested Reflow Profile [ SMD type products ] Heating the whole crystal unit in the dip mounting process should be avoided . Upright mounting is recommended ( to prevent applying heat directly to the body of a crystal unit ) . (3)Heating the whole body of the crystal unit , for example , in a reflow oven may affect the performance. The holder is small and is sealed by solder material by press sealing , so that such a reflow process is not allowed to be applied . (1) Low temperature solder reflow : For Sn62 , Pb36 , Ag2 , Sn63 , Pb37 alloy . Mercury's Green Program is implemented in accordance with the European Union's directive on "Restriction of the use of certain Hazardous Substance(RoHS)".Mercury's Lead-Free and RoHS Compliant products follow the EU directive (2002/95/EC) and include test reports issued by SGS Group on hazardous substances levels for the six substances:lead(pb),cadmium(cd),mercury www.jkoe.cn
