The use of ceramics in electronics has become more common over the last two decades, particularly with the increasing demand for long-lasting components that are designed to offer top performance even in the most demand environments and applications.
There are several advantages to choosing the new types of ceramic substrate materials. As with any type of product, it is not the right choice for every job, so understanding when ceramics are a consideration and when another material may be better will be essential. Talk to the design team and discuss options for materials, there will be a ceramic that will be an ideal match for the project.
High Risk of Corrosion
Unlike metals and alloys, a ceramic substrate is a material that is resistant to corrosion. This includes exposure to moisture, including humidity, which could lead to oxidation and fouling on electronic components over time.
When corrosion is a consideration, ceramics should be a primary consideration. This is particularly important in aerospace and automotive components as well as for medical devices and military and defense applications.
Long Life Cycles
With the ability to withstand high temperatures and temperature changes without becoming brittle or cracking, the use of a ceramic substrate material provides a strong, durable surface.
Many people may be surprised to find that the new ceramic formulations are actually harder than steel, resulting in printed circuits that will have a very long-life cycle.
Along with non-corrosive and non-reactive, the ceramic materials also provide superior insulation when used in components. The wires can be installed without a sheath or protective coating on the surface, and there is no risk of shorting.
Heat is also much less of a problem as the surfaces will resist overheating, which further adds to the ability of this material to stand up well even in very demanding ambient temperatures and working environments.
