C-MAC is one of the pioneers in thick film technology. We started screen printing in 1965.
Thick film technology means:
- High reliability
- High stability
- Excellent power handling
- Ability to combine analog, digital & power on a single substrate
- High temperature capability

Besides the standard sizes 4″x4″ & 5″x6″ (10.16×10.16cm & 12.70×15.24cm), we can handle sizes up to 5″x12″ (12.70×30.48cm).
metallisation & castellation
By means of hole metallisation (the equivalent of PCB vias) or castellation (similar to metallisation but only half a hole, situated on the border of the substrate), we can route signals from the top to the bottom of the substrate or allow connection to e.g. a PCB pad.
laser RESISTOR TRIMMING
For most applications, thick film resistors are screened with a lower value and laser trimmed to the correct value afterwards.
We offer standard trimming up to 1, 2 or 5% tolerance.
After aging, we can achieve an accuracy of up to 0.1%

TEST & (bad)marking
If required, the following actions can be performed:
- Continuity check
- Short circuit check
- High voltage breakdown test (up to 800V)
- General good mark
- Unit badmark
- Destroy functionality of bad parts
- Lasering of custom codes
