Flexible PCBs (FPC) are PCBs that can be bent or twisted without damaging the circuits, which means the boards can bend freely to conform to the desired shape in the applications. The material of the substrate is flexible, such as Polyamide, PEEK, or a conductive polyester film. DuPont manufactures  substrates and materials for rigid and flexible…

Rigid flex printed circuit boards (PCBs) provide designers with one of the more unique packaging methods for electronic designs.Combining the component and routing density of hardboards with the flexibility of flexible circuits, rigid flex PCBs allow designers to achieve routing density and interconnectivity that is not available in other types of circuit boards. Primarily used…

what is ceramic pcb thermal conductivity? The thermal conductivity of a ceramic PCB (Printed Circuit Board) refers to its ability to conduct heat. It is a measure of how well the material can transfer heat from one point to another. Ceramic PCBs are known for their high thermal conductivity, which allows them to efficiently dissipate…

PCB (printed circuit board) depaneling, also called singulation, is the process of removing numerous smaller,individual PCBs from a larger multi-PCB panel produced during manufacturing. The depaneling process was created in order to increase throughput of PCB manufacturing lines as circuit board sizes reduced.At CMS Laser, our depaneling process has the advantage of speed, pin-point accuracy,no tooling cost or wear, no…

When you begin to design your rigid flex PCB, there are a few rules you want to adhere to as best as possible: Pads and Vias on Flexible PCBs The pads used for your rigid flex PCB should have anchoring spurs, also known as tie-downs.The anchoring spurs help to ensure there is no separation between…

In modern days, flex circuit boards have become smaller, faster, and more complicated.Flex boards are typically used in high-frequency applications such as RF communication, telecommunication, computing using signal frequencies above 100MHz,high-speed signal processing, and high-quality analog video such as DDR, HDMI, Gigabit Ethernet, etc. Signal traces have impedance at each point on the signal path….

Ceramic PCB, also known as ceramic printed circuit board, is a type of circuit board that uses ceramic as the base material instead of traditional materials like fiberglass or epoxy. It offers several advantages over conventional PCBs, such as high thermal conductivity, excellent mechanical stability, and superior electrical performance. Ceramic PCBs are commonly used in…

The cost of ceramic PCBs is generally higher than FR4 PCBs. Ceramic PCBs are made from ceramic materials such as alumina or aluminum nitride, which are more expensive than the fiberglass material used in FR4 PCBs. Additionally, the manufacturing process for ceramic PCBs is more complex and requires specialized equipment, which adds to the cost….

A charging connector flex PCB board is a type of flex PCB that is specifically designed for use in charging connectors.It is a flexible circuit board that has a connector on one end and a charging port on the other end. The charging connector flex PCB board is used to connect the charging port of a device…

Isn’t it frustrating when you insert a button cell battery into a gadget only to get an error message? Don’t worry. You aren’t alone. Since several battery types look similar, most people can’t tell them apart.It’s also challenging to remember the battery names. Battery CR2025 vs. CR2032—they’re long, and they’re confusing. There’s also a clear…

Speed is an essential component of the rapid prototyping process.A custom quick turn PCB flex prototype is a common prototype manufacturing technique, and you can complete it in as little as one to three days. You will fabricate your PCBs and test them.This ensures that they meet your expectations and conform to stringent specifications during…

Flexible PCB coverlay’s major function is to protect the circuitry on the flexible PCB.It acts as the solder resist or solder mask for flexible printed circuit boards. Conventional solder masks or solder resist having limited ductility or flexibility.So for flexible printed circuits that need greater flexibility, flexible PCB coverlay is affixed on the circuit board for the…

While a well-designed flexible circuit will eliminate many connectors, ultimately most flexible circuits need to connect to something.Probably the most common entity that a flex circuit connects to is a rigid printed circuit board, but cable harnesses, polyester membrane switches, and even other flex circuits are also possible connection partners.The connection is usually done by a…

First let’s discuss the basics when it comes to a typical rigid PCB.During the production process with a rigid PCB, we would image and etch our inner layer cores, laminate them together, drill and plate with Electro Deposited copper (ED copper), and then move on to pattern plating.So you have copper foil with essentially three…

Boards are generally baked at 250°F (121°C) from two to ten hours,depending on the board thickness and design. Baking removes any moisture that may have been absorbed during processing. Polyimide films absorb moisture quickly; therefore, soldering and reflow should be done within 30 minutes after baking. Baking a rigid flex PCB is not recommended as…
