Ltcc Ceramic Powder

A low temperature co fired ceramic ltcc device is one of the most rapidly developed integral passive devices which provides a solution to the integration of passive components such as capacitor resistor inductor resonator and filter etc.

Ltcc ceramic powder. Ferro offers ltcc glass ceramic powder formulations with a wide range of k values for use in a variety of components across a vast range of frequencies. Chip filter chip antenna chip inductor capacitor high k er 40 low k er 8 rf smd component with 3 component design patents rn2 designs and manufactures rf smd components for amp rrh. Ltcc powder rn2 started as a ltcc powder maker and has 3 patents on ceramic compositions. Into a multilayered ceramic module by interconnecting each component in layers.

Composite powder for low temperature cofired ceramics is a composite material that is made by uniformly blending glass and ceramic fillers. Ltcc low temperature co fire ceramics is a multi layer glass ceramic substrate which is co fired with low resistance metal conductors at low firing temperature less than 1000. Firing can be conducted at a low temperature in the range of 870 900 c which allows the use of highly conductive elements such as gold and silver paste to create a screen print circuit pattern with high electric properties. Low temperature co fired ceramic ltcc is mixed powder of a glass and an alumina ceramic and it was used for the nonmagnetic pattern.

In order to allow the co firing of metals with high electrical conductivity the sintering temperature of the ceramic substrate has to be reduced well below the melting point of the individual metal e g. It is sometimes referred to as glass ceramics because its composition consists of glass and aluminum. Low temperature co fired ceramic ltcc materials systems offer the highest performance packaging solutions for high frequency devices in a wide variety of wireless telecommunication microwave automotive electronics ltcc blue tooth antenna module transmitter power amplifier filter component duplexer switch and more. The ceramic sintered at 785 c for 2 h exhibits excellent dielectric properties of ϵ r 2 86 q f 38093 ghz 16 0 ghz τ ƒ 2 17 ppm c which indicates that the ceramic is a promising candidate for ltcc applications.

The composite weight ratio of the glass powder and the alumina powder in the glass alumina composite material was 63 and 37.
