Zeta Materials

Zeta Materials ~ This changes everything!

Following is a brief overview of  Zeta materials.   If you have a need for a thin, fine line application or are looking for a solution to a pad cratering problem, contact us to learn more!

 First Imagine:  8 layers of Zeta Lam in a 10 layer PCB ~ Total thickness – 16 mils. 

Enabling next generation HDI.

The power of 50 microns at only 12 microns – harness the power of thicker boards in ultra-thin boards that are only 25% as thick.

Zeta glass free films provide less than 25 micron dielectric in a multilayer HDI package.
  •  Dk – Cap – 2.97 @ 10 GHz     Lam – 3.15 @ 10 GHz
  •  Df –  Cap – .006 @ 10GHz      Lam – .010 @ 10 GHz
  • Decomposition Temp – Cap > 500 C      Lam – 400 C
  • Glass Transition Temp –  180 C
  • Thermal Conductivity – Cap – .043 W/mK     Lam – .51 W/Mk
  • Low Z-Axis CTE
  • Low Moisture Absorption
  • Dimensionally Stable

Eliminates Pad Cratering

Pad cratering is a mechanically induced fracture in the resin between copper foil and the outermost layer of fiberglass of a PCB.  The pad remains connected to the component leaving a “crater” on the surface of the PCB.

Zeta Cap virtually eliminates pad cratering.  Once laminated to the surface as a cap, the resilient layer acts as a shock absorber to prevent fracture formation.   This material is more flexible than rigid, but 3 times stronger than flex.   Contact us for more detailed information!

Products:

Zeta Cap:  Next generation C-stage dielectric film designed to interface between the copper pad and the rest of the PCB.  It’s unique liquid-cast polyimide film is bonded to copper foil.  The ultra-thin film lays-up like a copper foil on prepreg in a conventional PCB manufacturing process.

Zeta Lam: Next generation dielectric film that facilities HDI build structures and minimizes the risk of pad cratering.  LAM is formed by laminating Zeta CAP to Zeta BOND, a proprietary B stage bonding film.  It acts like a glass dielectric in a conventional prepreg but is ultra-thin with guaranteed copper-to-copper Z axis standoff as thin as 12 micons.  It’s low CTE, High Tg and high Td make it suitable for sequential lamination cycles and higher-layer HDI structures.

Zeta Bond:  B-stage bonding film capable of filling circuits and vias.
