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.

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. 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.

It is sometimes referred to as glass ceramics because its composition consists of glass and aluminum. 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.

The composite weight ratio of the glass powder and the alumina powder in the glass alumina composite material was 63 and 37. 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. Ltcc sheet in unfired sometimes called green state is a thin flexible compound of ceramic or glass powder with organic composites. 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 dupont greentape 951 low temperature co fired ceramic ltcc material system combines the benefits of multilayer co fired ceramic and thick film technologies to meet the increasing demand for reliable electronics functioning in extreme heat and other harsh environments.
