IP9117

Description

IP9117 is a permanent blue 850 °C firing dielectric composition, displaying the following benefits:

Key Features

Expansion coefficient is closely matched with that of alumina, to provide for minimal substrate bowing Extremely dense, hermetic fired film allows for excellent electrical performance at a fired thickness of ≥ 40 μm Excellent solderability and adhesion of Ag. Ag/Pd, Ag/Pt, Au and Au/Pt conductors on top of dielectric Excellent wire bondability of gold conductors on top of dielectric Resistors can be processed on top of dielectric Absence of the “Battery Effect”3

Metal

30 – 50 Pas (25 °C, D = 75/s)

Coverage

c. 70 cm2/g (40 μm FFT)

Coverage

c. 70 cm2/g (40 μm FFT)

Storage and Paste Preparation

store (n a dry, cool
(5 – 25 °C) and dark place
with container tightly shut

Warranty

6 months

Printing Parameters

Print individual layers with a 200 – 325 mesh
stainless steel screen. For best via resolution,
a 325 mesh screen is recommended;
whenever possible, a double wet pass of the
squeegee is advised, to minimize pin holes.

Printing Speed

 

Drying Temperature

Dry at 150 °C for 10 – 20 minute

Process Temperature (TDS)

All layers of the interconnected structure should be fired separately. Fire in air, with a 30 – 60 minute cycle to a peak temperature of 850 °C.

Film Thickness

≥ 40 μm (3 separately fired layers)
