FAQ0158 Which PCB materials have a low coefficient of thermal expansion (CTE)?

Answer

Many Panasonic materials have excellent low coefficient of thermal expansion (CTE).
Low CTE is good for the through hole reliability.
Other properties such as Tg, Td and interlayer adhesion are significantly important to the reliability as well.
It is necessary to consider total balance of material properties and appropriate process conditions in order to improve PCB qualities.
