How to Read the Values of the Rect-
angular Type Chip Components
Example:
(a) Resistor
(b) Capacitor
Caution:
Once chip parts (Resistors, Capacitors, Transistors,
etc.) are removed, they must not be reused. Always
use a new part.
Pb (Lead) Free Solder
Pb free mark will be found on PCBs used Pb free
solder. (Refer to figure.) For PCBs with Pb free
mark, be sure to use Pb free solder. For PCBs
without Pb free mark, use standard solder.
Replacement Procedures for
Leadless (Chip) Components
The Following Procedures are Recom-
mended for the Replacement of the Lead-
less Components Used in this Unit.
1. Preparation for replacement
1.1. Pb free solder
a. Soldering Iron
Use a soldering iron for Pb free solder.
b. Solder
Be sure to use Pb free solder.
c. Soldering time
Do not apply heat for more than 4 seconds.
d. Preheating
Leadless capacitor must be preheated before
installation. (130°C~150°C, for about two minutes.)
