zUNLEADED SOLDER

Boards requiring use of unleaded solder are printed with the

lead-free mark (LF) indicating the solder contains no lead.

(Caution: Some printed circuit boards may not come printed

with the lead free mark due to their particular size.)

: LEAD FREE MARK

Unleaded 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

be applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set

to about 350°C.

Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

• Strong viscosity

Unleaded solder is more viscous (sticky, less prone to

flow) than ordinary solder so use caution not to let solder

bridges occur such as on IC pins, etc.

• Usable with ordinary solder

It is best to use only unleaded solder but unleaded solder

may also 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 dam-

aged by heat.

SERVICING NOTES

“REEL ASSY, CORD”INSTALLATION

Put the flexible board through the hole of the flexible holder.

Wind flexible board around the flexible holder.

Note :

Leave the flexible board for 20 to 30mm.

Attach the flexible holder to the "reel ASSY, cord".

Loosen flexible board doesn't seem to coil around the flexible holder.
