Multilayer PWB Material for High-Speed Mass-Volume Transmission

摘要：

A newly developed multilayer board material based on non-polarity structure PPE (polyphenylene-ether) has excellent dielectric properties (εr=3.5, tanδ=0.002 (1GHz)) and is capable of reducing transmission losses. The low coefficient of thermal expansion (Z-CTE) in the direction of the thickness (45×10-6/℃) provides a good through-hole reliability of PWBs with many layers and large thickness. The high thermal degradation temperature can resist the higher reflow temperature adopted for lead-free solder.The material is expected for use in high-end electronic equipment such as network equipment, large-scale computers, IC testers etc requiring high-speed information transmission and large-scale operations.
