Carbon ink printing
To avoid short-circuits in the PCB during carbon ink printing (it acts as a conductor) the following recommendations should be observed:
Carbon ink print
| Type | Characteristics | |
| SD2841 (PETERS) | Colour: | Black (mat) |
| Standard | IPC-SM-840C, Class H | |
| Surface resistance
(with coat thickness ~25µm) | ~ 20 Ohm/cm2 | |
| Conductivity | Very good | |
| Resistance to HAL | good | |
| Smooth surface |
