High-Frequency PCB

Electronic devices with high frequency are developing nowadays, especially in wireless networks. In addition, satellite communication is growing rapidly, and information products move towards high speed and high frequency.

What is high-frequency PCB?

High-frequency PCBs are often needed while developing new high-frequency products, such as satellite systems, radio frequency, microwave, mobile telephone base stations, etc. These communication products usually use high-frequency substrates when designing the PCB.

It has a frequency range of 500MHz to 2GHz, perfect for high-speed designs. Higher transmission frequencies can also give faster signal flow rates, which are critical in today’s increasingly sophisticated electronic switches and other components.

How are high-frequency PCB boards made?

Certain materials are necessary to attain the high frequency afforded by this sort of printed circuit board; any changes in the Er value of these materials can impact the board’s impedance. Many PCB designers turn to Rogers, Taconic, and Arlon dielectric material due to its lower dielectric loss, less signal loss, lower circuit fabrication cost, and greater appropriateness for rapid prototyping applications.

Besides selecting the suitable PCB material and finding the correct Er value, designers need to consider parameters such as conductor width and spacing and the substrate constant. These parameters must be precisely determined and implemented with the tightest process control possible.

What materials are used for high-frequency PCBs?

When it comes to the cost of FR4, PPO, and Teflon laminates, FR4 is the least expensive, while Teflon is the most costly. Teflon is the best in terms of DK, DF, water absorption, and frequency characteristics. Only Teflon PCB substrate can be used to produce products that require frequencies more than 10GHz. Teflon’s performance is significantly superior to that of other substrates, yet, Teflon has the disadvantage of great heat resistance.

Yes. Since we have all kinds of factories, we can offer a wide range of delivery times. Also, many of our volume factories have prototype services in-house, so both prototype and volume will be produced in the factory.

Yes, there are still a lot of PCB manufacturers inside Europe, and we have carefully selected PCB manufacturers as our suppliers for express prototyping, but also a producer of solder paste stencils for PCB soldering. This laser-cut solder paste stencil can be of various types, such as vector guard, zellflex, genesis, and more, but also multi-level stencil.

All deliveries will pass Multi-Teknik quality control, and we check quality with the CAM-prepared data made at the beginning of the process. You will also have a CoC and quality control document along with the delivered PCB.

The straight answer is no. You will have the correct quantity of PCBs and only pay for the correct ones. The x-outs are not considered when counting and will not be included in the amount on the delivery note.

Flex PCB is the same as the ordinary PCB, but with the difference that the base material is flexible. This is to let the circuit be able to be bent during a lifetime or be installed in a static folded mode. There are many design rules to take into account when designing flex PCB.

A PCB (printed circuit board) is a board with a printed copper pattern that forms a given circuit to enable the designer to connect several electronic components rationally. The most common material today for PCB boards is a combination of woven glass fiber and epoxy. For more demanding electronic designs, there are a lot of other base materials, such as ceramics, Teflon, polyimide, aluminum (mcpcb), and more.

The stack-up is the schematic view of how all copper layers, cores, and prepregs are grouped with data regarding thickness and material selections. Often impedance controlled PCB has this data in the stack-up view as well.

There is no exact date for the invention of the PCB; the truth is that it is a line of innovations that together contributed to today’s PCB. Of course, there is endless material about this on the Internet, but we have tried to pinpoint an unambiguous answer.

Mainly in China, where the world’s production is concentrated today, but also in Taiwan and inside Europe.

No one knows why just green became the standard color of PCB solder masks. But the rumor says that the electronic production staff in the USA during the second world war had voted about what colors were most friendly to eyes during a long time of work. And the green has become favorite.
