Flex PCB Manufacturing
The demand for flex PCB is increasing in all business segments, with especially strong demands from the medical, defense, and industrial markets. Since the volumes normally are quite small for these segments, Anpllopcb works with several HMLV (high-mix, low-volume) factories that fit the technology and volume requirement.
Low Cost Manufacturing Flexible PCB
If your project has you thinking of flex circuits, then Anpllopcb is the right place for you.
Whether you need a basic single-sided flexible circuit or a complex multi-layer flex solution, Anpllopcb can provide the assistance you need to get your idea to market. From flex and flex circuit design layout, board fabrication, or a fully assembled flex or rigid-flex circuit solution。
As a leading prototype-to-production flexible PCB manufacturer, we have flex and rigid-flex PCB capabilities that other companies can’t compete with. As your flexible circuit supplier, you will be able to build boards with line and width spacing down to 19 microns (.75 mil) and 1 mil micro vias. Please consult with our flex PCB design and engineering services team to help you determine what the optimal technologies are for your project’s application. We also offer extremely fast quick turn flex circuit prototyping services.

flex pcb benefits
There are some pretty amazing benefits to using flexible PCBs. Some of the advantages of flexible PCBs include the following:
- Reduced Space and Weight: Most advantages associated with flexible PCBs come from their low volume and weight. Using a flexible PCB instead of a rigid PCB can result in a space reduction of over 50 percent and a weight reduction of 95 percent while simultaneously maintaining the function and reliability of the circuit.
- Durability: The flexibility, reduced weight, and reduced number of interconnects in the PCB allow them to handle changing external forces and improve their resistance to shock and vibration.
- Signal Integrity: Flexible PCBs work in many environments, so signals will continue to perform smoothly despite exterior conditions. This improves the PCB’s signal reliability.
- Higher Density: The thin flex layers and smaller parts mean that flexible PCBs can support higher circuit densities.
- Minimized Errors: Due to the elimination of mechanical connectors and reduced variations in assembly methods, flexible PCBs experience reduced wiring errors.
- Low Cost: Because of the fewer assembly steps involved in creating flexible PCBs, they are relatively low-cost.
- Heat Dissipation: The thinner flex PCB materials allow for a greater surface-area-to-volume ratio, improving heat dissipation.
What is Flexible PCB？
Flexible printed circuits, also known as flex circuits, are sometimes considered printed circuit boards (PCB) that can bend when there are significant differences between PCBs and flex circuits regarding design, fabrication, and functionality. One common mistake designers make designing a flexible circuit using the same rules as a PCB. Flex circuits require a unique set-up and have their own design rules that the Hemeixin team has termed “flex-sizing” and have worked hard to perfect over the last years.
Flexible PCB, which is also called Flex PCB, Flexible circuit board, or flex circuit, consists of PI base material, an adhesive layer, a copper layer, an overlay, and sometimes with stiffeners. Flexible PCBs are now widely used to replace traditional FR4 PCB in various applications due to the benefits of flex PCB. Although more expensive than a normal rigid PCB, the right design in the right application could save weight and time in assembly, coupled with reliability, making a flexible circuit board a worthwhile consideration.
A flexible printed circuit consists of a metallic layer of traces, usually copper, bonded to a dielectric layer, usually polyimide. The thickness of the metal layer can be very thin (<.0001″) to very thick (> .010″), and the dielectric thickness can vary from .0005″ to .010″. Often an adhesive is used to bond the metal to the substrate, but other types of bonding, such as vapor deposition, can be used to attach the metal.
Because copper tends to oxidize readily, the exposed surfaces are often covered with a protective layer; gold or solder are the two most common materials because of their conductivity and environmental durability. For non-contact areas, a dielectric material protects the circuitry from oxidation or electrical shorting.
The number of material combinations that could go into a flexible printed circuit is nearly endless; current, capacitance, chemical and mechanical resistance, temperature extremes, and type of flexing are just some of the criteria that impact the material selections that best meet the functional needs. An experienced Anpllopcb design engineer considers critical requirements when designing a circuit to meet your needs.
Flexible printed circuit boards (FPC) have become a common component of electronic products due to their lightness and flexible performance. It is widely used in smart terminals, wearable electronics, consumer, automotive, industrial, and medical fields. The miniaturization and integrated function of electronics product development drive FPC to fine-line and multilayer design.
Fabrication
There are two basic processes for manufacturing a flexible printed circuit: subtractive and additive.
In a subtractive process, one starts with a solid area of metal, and the unwanted areas of metal are removed to form the traces. The two most common processes for defining the circuitry pattern are screen printing and photo imaging.
In an additive process, one starts with a bare dielectric layer, and the metallic traces are added only where needed to form the circuit. The conductive layer can be printed, plated, or deposited in a variety of manners.
The subtractive processes are more common because they are more robust and cost-effective and allow greater final product configuration choices. The circuits created by the additive process have the less current-carrying capability and environmental resistance than circuits created by the subtractive processes.
Finishing and Assembly
Surface finishing is usually required to ensure the printed circuit surface is ready for subsequent bonding, such as SMT assembly, wire bonding, or pressure connector insertion. Nickel or gold, tin, silver, and solder are excellent metals for this purpose. Organic coatings can also be used to protect the copper until the bonding process, which dissolves the material away.
There are countless assembly options for a flexible printed circuit. In addition to electronic components and connectors, various electrical or mechanical devices can be attached to a flexible circuit. The circuit can also be easily bonded to a curved surface or formed into any 3-dimensional shape. With proper construction, a flex circuit can handle dynamic flexing, making it the ideal interconnect solution for electronic packages that connect moving or rotating parts.
