IC substrate PCBs are mainly applied on electronic products with light weight, thinness and advancing functions, such as smart phones, laptop, tablet PC and network in fields of telecommunications, medical care, industrial control, aerospace and military.
Rigid PCBs have followed through a series of innovations from multilayer PCB, traditional HDI PCBs, SLP (substrate-like PCB) to IC substrate PCBs. SLP is just a type of rigid PCBs with similar fabrication process approximately semiconductor scale.
