Features
Higher reliability, better warpage control and thinner thickness. Material performance required for recent substrates and PCBs can be achieved by LαZ® which has excellent material property such as low CTE, high TG and high modulus.
Applications
Electronic Circuit
Package substrate, etc.
For applications that require higher reliability, better warpage control and thinner thickness boards for package substrates.
