Brief Introduction
Just as its name implies, high frequency is that the frequency is relatively high, generally refers
to the frequency of >=300 MHz (i.e. wave length <=1m), that is, the usual radio frequency band.
The electromagnetic wave of frequency >=1GHz is called microwave.
Typical frequencies for wireless applications:
* Current mobile: 0.9GHz - 2GHz
* 3G systems: 2.5GHz
* Bluetooth: 2.5GHz
* GPS: 12.6GHz
* LMDS: 24GHz and 40GHz
* Automotive: 77GHz
Market: RFID, Wireless communications, base station and antenna, amplifier, military products,
consumer electronics.
High frequency printed circuit board or microwave PCB refers to the printed circuit board made
on the high frequency (microwave) substrate copper clad plate. The common types are: Double
-sided board, multilayer board and mixed structure.
Mixed structure includes high performance special substrate, PP sheet + ordinary performance
board and PP sheet mixed pressing board; high frequency substrate + ordinary FR4 substrate;
high frequency substrate + metal base etc.
PCB Case: High Frequency PCB Taconic RF-35A2 20 mil
(0.508 mm) HASL
(Printed circuit boards are custom-made products, the picture and parameters shown are just
for reference)
General description
This is a type of high frequency PCB built on RF-35A2 20 mil substrate for the application of mixer.
It's a 2 layer RF PCB board at 0.6 mm thick. It's HASL finish with green solder mask and white
silkscreen. It's fabricated per IPC 6012 Class 2 using supplied Gerber data. Each 10 boards
are packed for shipment.
1.2 Features and benefits
Delamination of copper foil will not be caused by the change of cold and heat due to the consistency
with the thermal expansion coefficient of copper foil.
Heat resistance, chemical resistance, impact strength and peeling strength are good.
Reducing signal loss in high frequency application meets the development needs of communication
technology.
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.
Meeting your printed circuit board needs from PCB prototyping to mass volume production.
Strict WIP inspection and monitoring as well as working instruction,
High quality helps customers win cost-saving.
