High Freqency PCB Built on RO4350b and RO4450b with Blind Via

1.1 General descriptionThis is a type of 4 layer high frequency PCB circuit board built on RO4350B with RO4450B prepreg for the application of radar sensor board. It's a multilayer layer RF PCB board at 1.0 mm thick with immersion gold finish and solder mask and silkscreen. This board contains blind via from top layer to inner 1. Since it's asymmetric buildup,1.2% warpage is allowed. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 10 boards are packed for shipment.1.2 Features and benifits
1) Tg > 280 ºC
2) The dielectric constant (DK) is low and stable, so the signal transmission is good without delay.
3)Superior corrosion resistance.
4) 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.
5) Engineering design prevents problems from occurring in pre production.
6) Thermal stress test, reliability test, insulation resistance test and ionic contamination test,
7) High quality helps customers win cost-saving.
8) 1-10 pieces are offered .
9) UL conformed1.3 Application
