1. What factors should be considered when choosing the material for a PCB board?
Below factors should be considered when we choose the material for PCB:
The material’s Tg value should be greater than the operation temperature;
Low CTE material has good performance of thermal stability;
Good thermal resistance performance: Normally PCBs are required to resist 250℃ for at least 50s.
Good flatness; In consideration of the electrical properties, low loss/high permittivity material is used on high frequency PCB; Polyimide glass fiber substrate used for flexible PCB; Metal core is used when the product has strict requirement of heat dissipation.
2. What’s the merits of O-leading's rIgid-flex PCB?
SHINELINK’s rigid-flex PCB has the characters of both FPC and PCB, so it can be used in some special products. Some part is flexible while the other part rigid, it can help save product’s interior space, reduce product volume and improve performance.
3. How to you make the impedance calculation?
The impedance control system is done using some test coupons, the SI6000 soft and the CITS 500s equipment from POLAR INSTRUMENTS.
The equipment measures the impedance on a representative track configuration coupon of which the client has given us a determinate value and tolerance.
