Dear all
As I am not that long in the business, if have a lack in knowledge regarding CEM1- PCB materials.
If I remember right (starting as an electronican 24 years ago) CEM is a paper based PCB material single sided without through hole metallization.
In the internet I cannot find any information about CEM1 (maybe there is some from chines companies, but i Cannot read it).
Is this material still used in high volume somewhere (like in cameras...)
I thick it is still used sometimes in consumer products.
What are the recommendations for assembly and reflow process?
Can somebody forward me more information about CEM1 ... CEM3 or FR 1... FR3?
Thanks for your help
Siggi
