Lead-Free Solder; Fuse And Ic Link Replacement - Sony PMW-EX30 Service Manual

1-12-3. Lead-free Solder

Boards requiring use of lead-free 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 lead-free solder for the printed circuit board printed with the lead free mark.
. The lead-free solder melts at a temperature about 40 dC higher than the ordinary solder, therefore, it is
recommended 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 the heated tip is applied for too long, so
be careful.

The fuse and IC link are critical parts to safe operation.
Replace the components with Sony parts whose part number appear in the manual published by Sony. If
the components are replaced by any parts other than the specifi ed ones, this may cause a fi re or electric
shock.
c
If a fuse or IC link is replaced while the main power is kept on, this may cause electric shock.
Before replacing fuse or IC link, not only turn off the POWER switch but also remove the power cable
that is connected to the DC IN connector.
The AVP-11 board is equipped with fuse. The KY-633 board is equipped with IC link.
Any an excessive current fl ow due to abnormality inside the equipment, the fuse and IC link blow. If a
fuse or IC link blows, turn off the main power of the equipment once and inspect inside of the equipment
and remove the cause of excessive current. After that, replace the fuse and/or IC link.
