Whether you’re looking for prototype quantities or full production runs, we’ve got you covered. They offer the possibility to combine RF and digital electronic designs on one PCB. Typically, a hybrid PCB can use a mixture of FR-4 material with high-frequency PTFE material.
We use advanced technologies such as filling, measured impedance, via-in-pad, HF materials or manufacturing in the IPC Class 3 standard. Whether it’s quickly repeating designs or creating a wide range of products, these indispensable tools will help you ship a higher quality product in less time. This is one of the examples of hybrid stacking that I like to show in high-frequency PCB design courses.
My strategy of working with manufacturers to design a hybrid stackup is to start with materials I’ve used before. I usually do this with Rogers materials, but you could work with others. I will then send the fantastic house a suggested buildup to see if they can achieve my target tier layout. They then send a structure that they can do with the required number of layers and the dielectric/impedance data that incorporates the desired hybrid structure. From there, I can create the impedance design rules I need to design and route the design.
During extreme excursions (i.e. thermal shocks or repeated extreme cycles) some delamination may occur in the stacking. Some manufacturers may also tell you that this superstructure cannot be manufactured because you have placed adjacent PWRs and GIS on the two inner layers. If the board is small, it doesn’t matter; this board will not experience an arc until the wingspan reaches multi-U backplate sizes. You can also balance the inner layer with copper casting if necessary. The image below shows a 6-layer hybrid stack that I introduced in a previous post. This stackup is a good example of stackup for radar modules or other specialized applications of mmWave signals as images.
Aluminum/metal coated circuit boards are used as a base metal material to aid in the heat dissipation of printed circuit boards. The thickness of the metal cores at the PCB base is usually 30 to 125 thousand, but thicker and thinner plates are available depending on the application needs of the customer. Even after you’ve made a preliminary stack, you should send it to your manufacturer so they can inspect it before producing it. Sometimes you are not free to choose a low-loss laminate and material system that you want to use in a hybrid stack. Your manufacturer has a say in which materials are available, has a low lead time or has to outsource production. If you can review your stacking before creating the rest of your design, your manufacturer may recommend an alternative material system that supports the required PCB lamination process.
The answer is that flexible circuit boards already offer processing power with some flexibility. Such circuits have long been used in high-end applications for high-end automotive and multilayer pcb consumer electronics, such as cameras. FPCCs differ from FHE circuits in that the interconnects are not printed, but are etched by photolithography from a laminated copper sheet.
