Immersion Tin high frequency circuit board 

1.Product describe 

Layer: 2 layers 
Board: Ro4450B. 
Thickness: 0.5 mm 
Surface treatment: immersion gold/ HASL/Lead free HASL/ Immersion silver/Tin OSP,etc. 
Minimum aperture: 0.45mm. 
Application: communication. 
Features: high frequency board 

The growing data traffic is constantly driving the demand for faster signal transmission. In the electronics industry, PCBs have become high speed expressways, carrying billions of pulses per second. This capability needs special know-how in PCB design and manufacturing. High accuracy in the design and production is the key item required for control of capacity effects. 

Uniwell circuits supports you with designing high frequency PCBs (HF-PCBs). We help you to find suitable substrates, to define the trace dimensions and to calculate the impedance effects for you. Uniwell has a wide range of HF-PCB base materials on stock and can deliver your high frequency PCBs within the shortest possible time.
