TP High Frequency PCB
Introduction
Wangling’s TP material is a unique high-frequency thermoplastic
material in the industry. The dielectric layer of TP-type laminates
consists of ceramics and polyphenylene Oxide resin (PPO), without
fiberglass reinforcement. The dielectric constant can be precisely
adjusted by adjusting the ratio between ceramics and PPO resin. The
production process is special, and it has excellent dielectric
performance and high reliability.
Features
The dielectric constant can be arbitrarily selected within the
range of 3 to 25 according to circuit requirements, and it is
stable. Common dielectric constants include 3.0, 4.4, 6.0, 6.15,
9.2, 9.6, 10.2, 11, 16, and 20.
The material demonstrates low dielectric loss, with a slight
increase at higher frequencies. However, this increase is not
significant within the 10 GHz range.
For long-term operation, the material can withstand temperatures
ranging from -100°C to +150°C, showcasing excellent low-temperature
resistance. It's important to note that temperatures exceeding
180°C may result in deformation, copper foil peeling, and
significant changes in electrical performance.
The material exhibits radiation resistance and displays low
outgassing properties.
Furthermore, the adhesion between the copper foil and dielectric is
more reliable compared to ceramic substrates with vacuum coating.
PCB Capability
Let’s see our PCB Capability on TP materials.
Layer count: We offer single-sided and double-sided PCBs based on
the characteristics of the material.
Copper weight: We provide options of 1oz (35µm) and 2oz (70µm),
catering to different conductivity requirements.
Wide range of dielectric thicknesses are available, such as 0.5mm,
0.8mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 3.0mm, 4.0mm, 5.0mm, 6.0mm,
7.0mm, 8.0mm, 10.0mm, and 12.0mm, allowing flexibility in design
specifications.
Due to laminate size constraints, the maximum PCB we can provide is
150mm X 220mm.
Solder mask: We offer various solder mask colors, including green,
black, blue, yellow, red, and more, enabling customization and
visual distinction.
Our surface finish options include bare copper, HASL, ENIG,
immersion silver, immersion tin, OSP, pure gold, ENEPIG, and more,
ensuring compatibility with your specific requirements.
Applications
Displayed on the screen is a TP high-frequency PCB with a thickness
of 1.5mm, featuring OSP coating. TP high-frequency PCBs are also
utilized in applications such as Beidou, missile-borne systems,
fuzes, and miniaturized antennas etc.
Thank you. I’ll see you next time.
