Impedance Control PCB

https://www.hhcircuits.com/impedance-control-pcb

Impedance Control PCB , pcb circuit strictly control the trace width, thickness and dielectric thickness, pcb circuit tolerance of impedance trace ≤±5% is better for impedance matching, pcb circuit apply to High-frequency/high-speed devices and 5G communication equipment. HUIHE CIRCUITS Impedance Control PCB has passed ISO9001 / ISO13485 /IATF16949 / UL /RoHS / REACH certification.

 Impedance Control PCB List

 Classification Of Impedance

Characteristic Impedance: (Characteristic Impedance) When two conductors are insulated from the earth, the impedance between each other.

Differential Impedance: (Differential Impedance) the measured impedance between two conductors.

 Factors Affecting Impedance

A: The dielectric constant (TMr) is determined by the raw material. (Plate, prepreg)

B: Circuit thickness (T): Determined by raw materials and process capability.

C: Line width (w): Determined by the customer's design manuscript and process capability.

D: Media thickness (H): Determined by the customer's design manuscript and process capability and raw materials.

High Tg PCB

https://www.hhcircuits.com/high-tg-pcb

 High TG PCB, electric circuit board Glass transition temperature Tg≥170℃, electric circuit board High heat resistance is suitable for lead-free process, electric circuit board Used in instrumentation, microwave radio frequency equipment. HUIHE CIRCUITS High TG PCB has passed ISO9001 / ISO13485 /IATF16949 / UL/RoHS /REACH certification.

 High Tg PCB List

 What Is A High Tg Circuit Board?

Usually PCB circuit boards with Tg ≥ 170°C are called high Tg circuit boards. Generally, the Tg of the plate is above 130 degrees, the high Tg is generally greater than 170 degrees, and the medium Tg is about greater than 150 degrees. The Tg of the substrate is increased, and the characteristics of the heat resistance, moisture resistance, chemical resistance, and stability of the circuit board will be improved and improved. TG [TG: The highest temperature at which the base material maintains rigidity (℃)],The higher the value, the better the temperature resistance of the board.

 Advantages Of Using High Tg PCB?

PCB substrate materials will soften, deform, melt and other phenomena at high temperatures, and at the same time, they will also show a sharp decline in mechanical and electrical properties. Therefore, the difference between general FR-4 and high Tg FR-4 is the mechanical strength, dimensional stability, adhesion, water absorption, thermal decomposition, There are differences in various conditions such as thermal expansion, and high Tg products are obviously better than ordinary PCB substrate materials.
