Specification:

4 Layer Black Soldermask Immersion Gold High TG PCB Board In Panel Format

FR-4 material is a fire code rating, represents a material specification is meant a resin material through the combustion state must be self-extinguishing, it is not a material name, but a material grade. So now FR-4 grade material is typically used in circuit boards, there are many species, but most are based on the so-called four-function (Tera-Function) plus epoxy filler (Filler) and glass fiber made composite materials.

Defined impedance 4 layer black soldermask immersion gold board is: a good laminated structure will be able to play on the printed circuit board characteristic impedance control, the traces can be formed easily controlled and predictable transmission line structure is called impedance plate.

Current common characteristic impedance is divided into: single-ended (line) impedance differential (fixed) impedance coplanar impedance.

Single-ended (wire) Impedance: English single ended impedance, refers to a single signal line measured impedance.

Difference (Fixed) Impedance: English differential impedance, differential drive means to the test in two monospaced equally spaced transmission line impedance.

Coplanar impedance: English coplanar impedance, refers to the signal line at around GND / VCC (signal lines to both sides GND / VCC equal spacing) between the test transmission to the impedance.

Typical Applications

Cellular Base Station Antennas and Power Amplifiers

Microwave point to point (P2P) links

Automotive Radar and Sensors

low dielectric loss

Ballast, lights, navigation

The stability of the dielectric constant

An extremely low water imbibition

IT industry,Keyboard products

General FR-4 differs from high Tg FR-4: in the hot state, especially in the heat after moisture absorption, the mechanical strength of the material, dimensional stability, adhesion, water absorption, thermal decomposition, differences in thermal expansion and other various conditions, high Tg products significantly better than conventional PCB substrate material.

Competitive Advantage:

1) With UL,ROHS,ISO,IPC
2).Lead time:3-10 working days
3)Competitive price best quality
4).Rich 20 years experience in High Tg Multilayer PCB .
