PCBs with Cavities can thin electronic device profiles.

Press Release Summary:



Meeting electronic device thermal management and miniaturization demands, Cavity PCBs have structural recesses that enable additional functions. Cavities allow positioning of electronic components to give assembled PCB thinner structure. Applied to multilayer PCBs, process allows variations and layouts with several cavities and different depths (if desired) on one circuit board. Cavities can be made using Controlled Depth Routing, sequential lamination with low- or no-flow prepregs, or laser.

New Year - "New" Technology -- PCBs with Cavities



With the New Year upon us, Nujay Technologies, is eager to take on different types of PCB technology. We are starting to see a greater demand for PCB Cavities. The main driver behind this is the fact that the electronics industry is looking for smaller, more miniature products. There has been a large growing demand for smaller products, the limitations mostly due to the PCB layer count and material thickness.



A Growing Demand for PCB Cavities

PCB Cavities have played a large role in making electronic products get smaller. Cavity PCB's have structural recesses which enable additional functions compared to what a standard PCB can do.  The main drivers for cavities are thermal management and the miniaturization of electronic devices! The end customer is looking for an overall smaller product, therefore we are having more and more customers approach us looking for the Cavity PCB technology.



Cavities allow for the position of electronic components such as capacitors, transistors and logic modules, giving the assembled PCB a thinner overall structure. The process can be applied to multilayer PCB's and allows for different variations and layouts with several cavities and different depths if desired on a single circuit board.



There are various ways the PCB manufacturers create cavities on PCBs. The majority of the Cavity  boards are made using a Controlled Depth Routing process done with special routing machines. The cavities are plated if the design calls for it. Another way to produce cavities is with sequential lamination using low-flow or no-flow prepregs.



The third method is Laser cavities. Laser cavities are formed using a laser.

Laser cavities are a new technology for creating the smallest and finest deep milling grooves with the use of a laser. Applications that use to be impossible to produce are now possible. Laser cavities that are structured at the base, in particular, offer new possibilities for integrating flip chips into circuit boards.



Nujay has partnered with high quality suppliers who are working with PCB Cavities daily. We love to see the growing trend of smaller products which brings about new types of technology. Our team is eager to get more customers on board that use PCB Cavities!  Contact us today by phone at 949-215-8555/ 1-855-4PCB-LCD or by e-mail at sales@nujaytech.com.
