PN-G655E 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.
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.
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
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.
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.

*1 Cannot be used simultaneously.
*2 Does not support plug and play.
*3 Connection is allowed with an HDCP-compatible device only.
Does not support Repeater control function.
■ DIMENSIONAL DRAWINGS
Note: That the values shown are approximate values.
When mounting the monitor, read the manual of the brackets or stand
for their mounting procedure. The screw holes for mounting brackets
(M10 x 4 holes) are provided on the rear of the monitor.
Note that screw hole depth of the monitor is 20 mm. Loose holding may
cause the product to fall, resulting in serious personal injuries as well as
damage to the product. The screw and hole should come together with
over 10 mm length of thread. SHARP recommends using mounting
interface that comply with UL1678 standard.
