Rectangular Type Chip
Components
Example:
(a) Resistor
= 473 = 47 [kΩ]
(b) Capacitor
= Not shown
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 which use 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.
