1-5. HOW TO READ LEADLESS (CHIP) COMPONENT VALUE
1, Check the followings before S.M.D Troubleshooting
* Cracked or Chipped Component Body
* Cracked or Separated Solder Joints
* Peeling end Terminations or Fractured Leads
* Rejection of Solder from Copper Pads or Component
* Foreign Matter on Copper Pads
* Solder Bridges
2. §.M.D (Surface Mounted Devices) Identification
1) Chip Resistor Identification
Standard Chip Resistor Code

=12KQ
MULTIPLIER (0-9)
2nd SIG. DIGIT (0-9) i 470 f = 47x 10°(1) = 479
1st SIG. DIGIT (1-9)
| 00 | = CHIP JUMPER = 08
2) Chip Capacitor Identification
Standard Two Place Code
= 2.2 x 10° (1000)
