Products for ECU

ECU Components Maximizing
Characteristics of Ceramics
Murata helps improve the reliability and functionality of ECUs through its products that maximize the characteristics of ceramics, such as high-temperature resistance and vibration resistance. Murata also accommodates various demands including those for electromechanical modules and mounting by Electrically conductive adhesive.

Ceramic Substrates

Low Temperature Co-fired Ceramic Functional Substrates

LFC® substrates provide high reliability under punishing conditions such as high temperatures and strong vibration.

  • LFC® substrates are ceramic substrates using Ag with low-resistance for conductive material. They are used for multilayer high-density wiring substrate for automobile multi-chip modules where high reliability is required under high temperature such as in engine rooms.
  • Eight-inch-square low-temperature co-fired ceramic substrates (LTCC), the world’s largest size, realize high dimensional accuracy and a very flat surface at 0.05% and 5μm/4mm respectively.
  • This material is made with lead- and cadmium-free, environmentally friendly materials, and is one on which electroless Ni/Au plating can easily be applied. It can also be formed into very reliable printed resistors that are essential for automobile-use substrates.
