Generally, the land width should be 0.7 to 0.8 times (W) of the width of chip resistor. In case of reflow soldering, solder amount can be adjusted, therefore the land width should be set to 1.0 to 1.3 times chip resistor width (W).

For soldering (Example : Sn/Pb) Preheating Main heating Peak Peak Time 60 s to 120 s Above 200 C 30 s to 40 s 235 5 C max. 10 s For lead-free soldering (Example : Sn/Ag/Cu) Temperature Time Preheating Temperature Temperature 140 C to 160 C Preheating Heating Main heating Peak 150 C to 180 C 60 s to 120 s Above 230 C 30 s to 40 s max. 260 C max. 10 s Time l Recommended soldering conditions for flow For soldering For lead-free soldering Temperature Time Temperature Time Preheating 140 C to 160 C 60 s to 120 s 150 C to 180 C 60 s to 120 s Soldering 2455 C 20 s to 30 s max. 260 C max. 10 s Safety Precautions 1. If transient load (heavy load in a short time) like pulse is to be applied, carry out an evaluation and confirmation test with the resistors actually mounted on the board. When a load of more than the rated power is applied under load condition at steady state, it could impair performance and/or reliability of the resistor. Never exceed the specified rated power. 2. Chlorine type or other highly-reactive flux is not recommended. Residue could affect performance or reliability of the resistors. 3. When using a soldering iron, never let the tip of the soldering iron touch the body of the chip resistor. When using a soldering iron with a tip at a high temperature, solder for as short time as possible (no more than three seconds and up to 350 C). 4. Avoid physical shock to the resistor and nipping of the resistor with hard tool ( pliers or tweezers) as it may damage protective coating or the body of the resistor and may affect its performance.
