The demand for flex PCBs is exploding as a result of the proliferation of consumer electronics that require a thinner, lighter circuit board. Flexible circuit boards can be made with a variety of copper thicknesses and layer counts, providing the flexibility and performance needed for many applications. They can also be used in more dynamic environments than traditional rigid PCBs. Flex PCBs are ideal for a range of high-value, low-volume production applications, including mobile devices, medical wearables, robotics, and automotive components.
Choosing a flex pcb supplier isn’t an easy task, but there are several key tips that you should follow when making your choice. The first thing to look for is a manufacturer that adheres to industry standards. A good flex pcb supplier will be certified by an internationally recognized body such as ISO 9001:2008, and have years of experience. They should have the ability to work with both rigid and flex PCBs, as well as provide prototypes for a quick turnaround.
In addition to meeting manufacturing rules and certifications, you should look for a flex pcb supplier that offers competitive pricing. To get the best price, you should request a quote from multiple manufacturers and compare their capabilities and features. Lastly, make sure that the manufacturer can meet your deadlines and is capable of handling engineering changes.
How do flex PCB suppliers handle engineering changes?
When designing a flex circuit, be cautious when routing traces near bend areas. These areas need to be avoided if possible, as they can cause damage to the vias and pins. If it is necessary to route near these areas, then the traces should be staggered instead of being adjacent to one another. This will help avoid exposing the ends of the traces to the bending force.
Another consideration is the material. Rigid PCBs are typically made from FR4 glass-epoxy compounds, while flex circuits are built using polyimide. The stiffeners in rigid boards are laminated to the FR4, while flex circuits use a PSA (pressure sensitive adhesive) to attach the stiffener materials to the board.
A flex pcb supplier should be able to handle a variety of different finishes. For example, a tin finish will cover the pads and resistors on the board, while a soft gold covering can be applied to areas where soldering is required. Adding these finishes will increase the cost of the flex circuit, but it will give it the look and feel that you need for your design.
Considering the advantages of a flex circuit, it is essential to consider the design and assembly process when deciding which type of PCB you need for your application. In addition to a thorough evaluation of the manufacturer, it is important to review the quality of the product. This includes electrical test results, flex cycle endurance tests, and dynamic bending tests.
Flex PCBs are well-suited to the Internet of Things (IoT) ecosystem because they can be curved into tight spaces, allowing them to connect to sensors and other devices. This helps the IoT ecosystem to be more efficient and reduce costs by eliminating wiring harnesses, reducing weight, and increasing reliability in dynamic environments. In addition to this, flex circuits can accommodate more complex shapes, and have the potential to add 3D functionality.
