10L High Frequency PCB Manufacturer Rogers &Isola Hybrid PCB Example

Usually, these laminates need to fit in another room, and there are times when the circuit board has different twists and turns. For a hybrid design, routing the contours of the PCB is a delicate procedure. Speeds and power supplies should be lowered to ensure that the edges remain sharp. The adhesion is good and the reliability of the breadboard is not abnormal.

If printing is done via digital methods, such as inkjet or aerosol, the prototype times of circuits are significantly reduced compared to conventional engraving, because there is no need to design and manufacture masks. Such a transition to a more flexible development process makes it possible to make much smaller volumes of printed circuit boards cheaply and even facilitates custom circuits. Thanks to our experience and exceptional technological training, we are able to produce a wide range of special printed circuit boards, directly adapted to your needs. The design of the high-frequency hybrid PCB is based on cost savings, increased bending strength, electromagnetic interference control and other factors.

This is because FR4 at microwave frequencies suffers a high dielectric loss, causing problems with signal integrity. PCB Trace Technologies Inc. has extensive experience in handling various laminates due to their physical properties and the capabilities of our equipment. We have this critical experience in producing PCBs with different materials. With high-frequency hybrid PCBs, both HF material and regular material are used on the same circuit board. This can meet the requirements of high frequency and regular frequency.

For thermal management solutions, you need to use special PP to dissipate heat. According to Isola, the biggest challenge in fabricating a hybrid PCB layer stack with PTFE is permanent deformation during thermal cycles (backflow and/or pressure), even if it does not result in delamination. This is another side effect of higher CTE multilayer pcb values in PTFE compared to FR4 materials (about 2 times the difference on the z-axis). The main factor that creates the risk of delamination is not the binding strength between layers, but the CTE value. CTE differences cause one material to expand faster than another, creating layers as the plate is heated to high temperatures.

Flat resistors are also screen printed and incorporated into the thick film interconnect design. The composition and dimensions of the resistors can be selected to deliver the desired values. The final value of the resistance is determined by the design and can be adjusted by laser cutting. Once the hybrid circuit is fully filled with components, fine-tuning can be achieved prior to the final test by active laser trimming. With the rapid development of electronic communication technology, to achieve high-speed and high-fidelity signal transmission, microwave RF PCBs are increasingly used in communication equipment.

Design, production and assembly of single-stop hybrid PCBs, from prototypes to bulky production. You can use 2 different types of base materials to make your PCB, and 3 or 4 types are fine too! For example, we produce the following high-frequency hybrid PCBs using 4 types of materials: Rogers RT 6202, FR4, ceramics and copper.

The values represent the level of dimensional changes that each material will undergo when exposed to different temperatures. When these laminates are combined, they complement each other by reducing the negative properties of some materials and increasing the strength of some properties. For example, PTFE offers excellent electrical properties, but may have problems with its structural properties when exposed to certain temperatures. Hybrid PCB manufacturing involves the use of PTFE laminates and FR-4 material. When designing a hybrid PCB, it is very important to know the right materials used for it.
