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….

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…

A beta layout flex PCB is a type of printed circuit board that is designed to be flexible and bendable.It is typically used in applications where a rigid PCB would not be suitable, such as in wearable technology, medical devices, and other applications where space is limited. The layout of a beta layout flex PCB is designed…

With the continuous enhancement of electronic device functionalities, their sizes have been continuously shrinking.In order to meet the functional requirements of these smaller devices, component packaging technologies have also been advancing. Since the late 1980s, Ball Grid Array (BGA) has emerged as one of the most popular packaging technologies,making significant contributions to meet this demand….

Circuit bookbinding is one of the best practices employed by Hemeixin engineers for creating stacked PCBs.For flex PCBs, we offered a 12 layer flex PCB board with bookbinding. An additional small length is added to the circuit, making it move in an outward direction from the bend radius.There are copper traces placed at right angles to the…

This is also called the stable flex and involves the flex layer to be bent into shape to fit into a design.The bend is introduced in the beginning, and the layer is not subjected to further stress. For one or two layers, the minimum bend radius can be 6X, while for multiple layers, it can…
