Nowadays, ceramic PCBs are widely used because of their high thermal conductivity, low CTE, low dielectric constant, and resistance to chemical attack.
Ceramic printed circuit boards are printed with conductive paths on a ceramic substrate. The ceramic used in ceramic PCBs is different from the ceramic used in flooring, which is a special material called "fine ceramic". Ceramic PCBs are divided into high-temperature ceramic PCBs, low-temperature ceramic PCBs, and thick-film ceramic PCBs, which will be introduced in detail in this article.
High-temperature ceramic PCBs have sometimes referred to as high-temperature co-fired ceramic (HTCC) circuits. These boards are designed for high temperatures and are manufactured in a unique way. To create new ceramics, the process combines solvents, plasticizers, binders, alumina, and lubricants.
Low-temperature ceramic PCBs are sometimes referred to as low-temperature co-fired ceramic (LTTC) circuits. LTTC PCBs are designed for low temperatures and are manufactured using a different process than high-temperature ceramic PCBs. adhesive substances and crystal glass are used to make the LTTC PCBs. both of which are coated with gold paste on a metal board.
LTTC PCBs have better shrinkage tolerance and less warpage. The thermal advantages of LTCC PCBs make them more suitable for heat-free products such as LED lamps.
Manufacturing this type of PCB requires coating the ceramic substrate with dielectric and gold paste and baking at 1000 degrees Celsius or lower. Thick film ceramic is preferred because it prevents copper oxidation.
Ceramic PCBs are used in a wide range of applications and are typically used in the following applications.
Power controllers
Spotlights and high-current LEDs
Variable optical systems
Converters
Audio amplifiers
Power Supply Applications
Automotive power conditioners
Solar Cell Substrates
Printers
Semiconductor cooling devices
IC arrays
High Power Transistors and Transistor Arrays
Industrial power devices
