Circuit Protection Parts (Fuse/Ic Link); Unleaded Solder - Sony DSR-DR1000 Service Manual

2-6. Circuit Protection Parts (Fuse/IC
Link)
The circuit protection parts such as fuse and IC link are
mounted on the DDE-18, DEN-20, DPR-224 and DY-19
boards.
w
. The fuse and IC link are important parts for ensuring
safety.
Replacement with parts other than those designated will
result in fire hazards and electric hazards. Therefore be
sure to use only designated parts.
. If the replacement work for fuse or IC link is attempted
with the power ON, this may result in electric shock.
When replacing the fuse or IC link, not only turns off the
power of the unit but disconnects the power cord con-
nected to the POWER connector.

2-7. Unleaded Solder

Boards requiring use of unleaded solder are printed with a
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
m
. Be sure to use the unleaded solder for the printed circuit
board printed with the lead free mark.
. The unleaded solder melts at a temperature about 40 d
higher than the ordinary solder, therefore, it is recom-
mended to use the soldering iron having a temperature
regulator.
. The ordinary soldering iron can be used but the iron tip
has to be applied to the solder joint for a slightly longer
time. The printed pattern (copper foil) may peel away if
Part No.
the heated tip is applied for too long, so be careful.
