Our company specializes in producing large size low warpage alumina ceramic substrates that are essential components in a wide range of electronic devices. These substrates are made from raw materials that are often mixed with iron-containing oxides.
However, during high temperature sintering, these products can develop red spots, which not only affect the whiteness of the product but also the electrical properties such as volume resistivity and dielectric strength. To address this issue, our company has developed a unique iron removal process that reduces the inclusion of iron content by more than 95%. This process greatly improves the electrical properties of the ceramic substrate, ensuring high performance and reliability in electronic applications.
One common issue with ceramic substrates produced by tape-casting is the presence of camber, especially in thinner products. Conventional products like 120*120*0.5, 127*127*0.5, and 138*190*0.5/0.635 typically have more than 0.3% camber. To combat this, our company utilizes a special flat-firing technique that reduces the camber to less than 0.25%, ensuring a flat and uniform surface for optimal performance. Our core products include large size ceramic substrates like 240*280*1mm and 95*400*1mm, which have been well-received by our customers for their high quality and reliability. These large size substrates are essential for applications that require a larger surface area, such as power electronics, LED lighting, and automotive sensors.
In conclusion, our company is dedicated to producing high-quality ceramic substrates that meet the stringent requirements of modern electronic devices. With our advanced manufacturing processes and innovative techniques, we are able to offer large size low warpage alumina ceramic substrates that deliver exceptional performance and reliability.
