1. What Is a Flexible Circuit Board?
A flexible circuit board is a PCB that has been specially designed to be flexible. Flexibility is the essential feature of these boards, and it is the reason why they are becoming so popular.
Flex PCBs have a wide application field, including but not limited to:
- Automotive electronics
- Computer electronics
- Industrial applications
- Medical field
You can use them wherever you need adaptability from the circuit board. If you realize that you require a bending circuit during the assembly process, flex PCBs will be the ideal solution.
Special Manufacturing Processes
Flexible printed circuit board manufacturers use two different processes when designing a flex PCB:
- Subtractive – in the beginning, you have a whole piece of metal, and then you remove (subtract) the unnecessary part. Screen printing and photo imaging assist in defining the pattern of the circuit. The creators prefer using this approach since it is more affordable and allows plenty of freedom in configuring the board.
- Additive – here, the designer has only a bare dielectric layer in the beginning. Forming the circuit is the ultimate goal, and the creator adds metallic traces wherever it is necessary to do that.
Ultimately, the manufacturers use surface finishing to ensure that flex PCBs are ready for future bonding.
Advantages and Benefits of Flexible Circuit Boards
- Reliability and durability – you get a long-lasting product that will deliver consistent performance.
- High-temperature applications – as long as you go with reliable, flexible printed circuit board manufacturers, you will be sure that their product can withstand high temperatures.
- Completely flexible and pliable – if you can’t avoid warping or bending, these boards are your best choice.
- Can accommodate any design – you can demonstrate maximum creativity and pursue the preferred design knowing that the board can provide it.
- Component/connector assembly – flex PCBs are suitable for any connector or component used in rigid board design.
- Package size and weight reduction – thanks to flex boards, you can decrease the overall size of items.
2.Factors to Consider a Flex-PCB Manufacturer
Before you can move to choose the right manufacturers, let’s make an overview of the factors you should consider in the process.
You should strive to find flexible printed circuit board manufacturers that put in maximum effort to ensure maximum accuracy and decrease potential risk factors that may lead to the board’s failure.
Key Design Factor
The experts suggest that the critical factor the creators should apply is ensuring the optimal distance between the center of the material stack and the neutral bend axis. The goal is to keep the length as short as possible as that will enable even distribution of forces when the PCB is flexing.
Some other risk factors are:
- Bending it too much (keeping the angle low is better)
- The thickness of the PCB – thinner boards are better
- Inadequate materials – it is always essential that the manufacturers use materials of premium quality
While we are on the topic, let’s mention that environmental factors can also lead to the failure of a flex PCB. Here is the list of items that can increase the risk of damage:
- Humidity – water and moisture can lead to a shortage if they cross board’s channels. High levels of humidity can lead to mold, which increases damage risk, too.
- Dust – it can decrease the capability of the board to keep optimal temperature by preventing heat dissipation. That can lead to overheating and destroy the unit.
- Extreme temperatures – both heat and cold can damage circuit boards. Cold leads to condensation, while heat can lead to unwanted warping and ultimate destruction of plastic or metal parts of the PCB.
- Static electricity – the experts strongly recommend avoiding any static electricity when the board is in use as it can lead to series damage. That means you shouldn’t have carpets or fabrics that can create in near your board.
- Liquid and gaseous chemicals – some fumes can lead to corrosion, and even cleaning solutions may cause damage to the unit.
Factors to Consider When Selecting a Manufacturer
Now that you are aware of potential design flaws and risks, you know what to be mindful of when selecting and using a flex PCB. Now, let’s take a look at some tips you can use when picking from the available flexible printed circuit board manufacturers:
- Manufacturing capabilities and processes – you want to ensure that the manufacturer has the right type of equipment to fulfill your demands and expectations.
- Is the experience rich? – the company needs to provide outstanding customer service and be ready to answer any question you might have.
- Lead time and delivery time – you should make sure that they can complete the order in the shortest possible timeframe, as well as deliver it as soon as possible.
- Quality – the product you receive should be of the highest quality to ensure that you made a smart investment.
- Price – it is only wise to consider the price, too. The main objective should be that you get an excellent value for the cost.
- One-stop turnkey service – ultimately, it is vital to ensure that a single company can provide everything you may need related to flex PCBs.
