Ken,

I'm not sure where it would fit in, but you might want to reference
IPC-4101, "Specification for Base Materials for rigid and Multilayer
Printed Boards."

As you delve into 4101, you will find that you CAN get more specific in
specifying materials, if you feel you NEED to.

Good luck.

Subject:  [TN] Fab note for Laminate material




Currently my fab note says...
MATERIAL: X THICK GLASS EPOXY, NATURAL COLOR, LAMINATED NEMA GRADE FR-4, 1
OUNCE COPPER.

I believe above is for regular material with Tg of 110C but I want to use
high Tg material, so how should I rewrite it...like

MATERIAL: X THICK GLASS EPOXY, NATURAL COLOR, LAMINATED NEMA GRADE FR-406,
TETRA II OR EQUIVALENT SUBSTARTE MATERIAL WITH MIMIMUM 165 DEGREE C Tg, 1
OUNCE COPPER.

or something different.

re,
Ken patel
