Project Goals
Phase I:
Electrically test commonly used high frequency (below IPC Df) laminate materials:
* Including all commercial “halogen-free” laminate materials, not “new” materials (not in volume production)
* Using all viable electrical test methods for speeds above 2 GHz.
Phase II:
Reliability testing including IST test coupons from common test vehicles made using the “halogen-free” laminate materials.
Note: The term “halogen-free” used herein refers to bromine or brominated compounds not being used in the resin formulation.

Project Details
1) Determine the lower loss laminate materials to be tested. Ref. Slide #5: Draft list of set of these laminate materials to be tested.
2) Phase I testing to include several baseline non-halogen-free laminate(s). Examples: Isola 408HR and/or IS-415.
3) Standardize on available copper foil type with controlled, constant copper roughness and dielectric construction.
4) In a later phase potentially evaluate alternate constructions.
5) Testing
a) Loss Tangent(Df)and Er (Dk) at 2 GHz, 10 GHz, up to GHz where possible, all completely dried with 0X or 6X 260 C preconditioning.
* Test Methods: SPP(IBM), SET2DIL(Intel), Bereskin Stripline, EBW, Stripline (IPC ), Split Post Dielectric Resonator Cavity (IPC ), Tri-plate Line Resonator (JPCA-TM001), CISCO.
