UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed withthe lead free mark due to their particular size.)

: LEAD FREE MARKUnleaded solder has the following characteristics.• Unleaded solder melts at a temperature about 40°C higher than

ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350°C.Caution: The printed pattern (copper foil) may peel away if theheated tip is applied for too long, so be careful!

• Strong viscosityUnleaded solder is more viscous (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.

• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

Notes on Chip Component Replacement• Never reuse a disconnected chip component.• Notice that the minus side of a tantalum capacitor may be

damaged by heat.
