1 High Frequency Test Methods for Laminate Materials (HF) Project HDPUG May 18, 2011

2 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 Goals

3 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 ) 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.

4 Project Details, Cont. 5) Testing, Cont. b) IST Testing (Phase II) * Preconditioning 6X at 260 C * 500 Cycles, Peak Temp 150 C * Weibull Plot of failures * Crossection checks for delamination

5 Laminate Materials Draft list high frequency laminate materials includes the following halogen-free laminate materials; Df (0.007 to 2 GHz): * EMC EM-828* EMC EM-285 * EMC EM-370-D* Grace GA-HF-17 * Hitachi 679(HE)* Hitachi 679H * Hitachi 67(G,H)* Hitachi LZ-71G * ITEQ IT-170GRA* ITEQ IT-168G * Panasonic R-1566W* TUC TU-862HF

6 Project Milestones 1) Generation of standard test board design and construction stackup. 2) Suppliers commit to supply the laminate materials to be tested. 3) Labs/test sites committed for the before and after 6X at 260 C preconditioning. 4) Labs/test sites committed to perform the Loss Tangent(Df)and Er (Dk) at 2 GHz, 10 GHz, and up to GHz where possible. * SPP(IBM)* SET2DIL(Intel) : * Bereskin Stripline(Isola) : * EBW, Stripline (IPC ) : * Split Post Dielectric Resonator Cavity (IPC ) : * Tri-plate Line Resonator (JPCA-TM001) : 5) Phase II labs/test sites committed.
