PN-655E LEAD-FREE SOLDER
■ LEAD-FREE SOLDER
The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder. The
alphabet following the “LF” mark shows the kind of lead-free solder.
Example:
(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread. Never use conventional lead solder thread, which may cause a breakdown or an
accident.
accident.
Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the exclusive-use solder-
ing iron is recommendable.
(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering capacity
is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land separation or may
exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when completion of soldering is
confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron tip after com-
pletion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.

COMPATIBLE SIGNAL TIMING
• All are compliant only with non-interlaced.
• Depending on the connected PC, images may not be displayed prop-
erly even if the compatible signal described above is input.
• If the monitor is receiving timing signals that are not compatible, [OUT
OF TIMING] may appear. In this case, please change the setting so
that the timing signals will be compatible with the monitor, according
that the timing signals will be compatible with the monitor, according
to your PC manual.
• If the monitor is not receiving any signal (sync signal), [NO SIGNAL]
will appear.
• The frequency values for the Sun Ultra Series are reference values.
A separate conversion adapter (commercially available) may be
required for connecting the monitor to the Sun Ultra Series.
