S Miller,
Thermount is manufactured by a company called
Arlon.
It is equivelant to what DuPont
manufactures which is called Kevlar.
You are correct in that they probably offer the
lowest CTE
available for material supplies. My previous
company
AIT-Atlanta(Advanced Interconnection Technology)
still manufactures
boards using these materials for military
applications.
The contact would be Dominic DeDuonni

Subject: [TN] Thermount Laminate
Happy Holidays to All,
We have a couple of board designs that have LCCCs (Leadless Ceramic
Chip Carriers) and our domestic PCB supplier has recommended that we use a
different laminate substrate other than the traditional FR-4 that has a CTE
close to the ceramic on the chip.
It has been suggested that
they use a laminate called Thermount.
Being on unfamilar
ground, I was wondering if any of you could lend assistance by providing:
- Do you we know of any suppliers that currently manufacture
PCB's using Thermount?
- What is the price difference between FR4
and Thermount? (Please advise in percentages)
- Is there a suitable
alternative that will work that has similar properties of Thermount?
Any and all feedback would be truly appreciated.
Regards,
