Hello,
Because I didn't recieve any reply's I'm reposting this question.
I have a few questions about IPC 2222 page 11 figure 4-2.
For good electricals and high CTI, FR-6 or CRM-5 should be used.
Does CTI mean Comparitive Tracking Index and if so what is
the definition of it ?
We have never heard before about FR-6.
What kind of materials are FR-6 and CRM-5 ?
I hope sombody can help me out with these questions.
Thanks,
Bas van Zalk
