# What’s the difference between thick film ceramic PCB and DCB ceramic PCB?

_Published: 2016-08-12_

 

- Conductor (trace) Thickness: thick film ceramic PCB is 10~20um, DCB ceramic PCB is 0.1, 0.2, 0.3mm
- The conductor(trace) for thick film ceramic PCB is Au or AgPd, DCB ceramic PCB’s conductor is copper.
- Min trace width/space:thick film ceramic PCB is 300um (250um for prototype), DCB ceramic PCB is 0.3, 0.4, 0.5mm
- PTH (Plated Through Hole) is available for thick film ceramic PCB, but it is unavailable for DCB ceramic PCB now.
- 2 layers traces on the same top side and more than 4 layers traces for thick film ceramic PCB, but can not do this for DCB ceramic PCB now.
