LTCC PCB Prototype Fabrication

LTCC stands for a ceramic material system used as a low-cost substrate technology in electrical and electronic engineering. It can accommodate an almost infinite number of stacked layers. The conductor paths are usually made of gold or silver thick film pastes. The metallization layers are silkscreen printed one by one onto the unfired "green" ceramic tape; once the setup has been stacked and printed, it is fired in the process oven. The sintering temperature for LTCC is below 900°C, a relatively low temperature which allows the use of gold and silver conductive traces. LTCC technology is especially useful for microwave applications because ceramic substrates and gold or silver conductive layers have excellent physical and electrical properties. LTCC PCB also has the advantage of competitive material and processing costs compared to other substrate systems like HTCC and printed circuitboards (PCB / PTFE), such as laminated substrates.
