Immersion Gold RF PCB Built on RO4350B 30mil With 2 Layer Copper
(PCB’s are custom-made products, the picture and parameters shown
are just for reference)
General description
This is a type of dual layer PCB built on 30mil RO4350B substrate
with Tg 280°C for the application of Antenna WiFi. It's 0.8 mm
thick with white silkscreen (Taiyo) on green solder mask (Taiyo)
and immersion gold on pads. All vias are designed with
open-solder-mask. The base material is from Rogers supplying 2
designs 2 up PCBs per panel to save cost. They're fabricated per
IPC 6012 Class 2 using supplied Gerber data. Each 50 panels are
packed for shipment.
Features and benefits
Good high temperature and low temperature resistance.(-192℃-260℃)
RO4350B exhibits a stable dielectric constant over a broad
frequency range. This makes it an ideal substrate for broadband
applications.
Stable electrical coefficient of dielectric constant.
Immersion gold has excellent surface planarity, particularly
helpful for PCBs with BGA packages or even CSP mounted components
to reduce failure rate during assembly and soldering.
High voltage test, Impedance control test, micro-section,
solder-ability test,
Right manufacturing instruction (MI),
Delivery on time: >98%
Eligible products rate of first production: >95%
Competitive price
Application
Splitter, Variocoupler, Microstrip antenna, 3G antenna, Relay
Stations, RF Switches
