FPC PCBs Withstand High Temperatures
A flex circuit, or FPC PCB, routes electrical signals through conductive pathways and offers greater flexibility than a traditional circuit board. It can be found in items like solar power cells, cell phones and vehicles that require a high degree of flexibility. Its flexible structure also makes it lighter and thinner than a traditional circuit board, while still maintaining durability and functionality.
A flexible printed circuit board can withstand high temperatures, but you need to ensure the right design is used. For instance, it is important to consider the thickness of the copper layers, as thinner ones are prone to cracking under excessive stress. Similarly, it is important to avoid placing critical components in areas with sharp bends as this can cause fatigue over time. You should also choose a flex circuit with enough redundant traces to provide backup if the original traces become damaged.
The surface treatment process on the conductive copper layer of an fpc pcb can influence its temperature resistance. In general, immersion gold is the preferred method, although anti-oxidation (OSP) is sometimes used due to its lower price. Both can withstand high temperatures, but the former has a higher environmental endurance.

Another factor that affects an FPC’s ability to withstand high temperatures is the adhesive used in its manufacturing. A quality adhesive is essential to ensuring that the conductive tracks and insulation substrate base remain securely joined together. It also prevents moisture, dust or other external agents from corroding or oxidizing the conductive surface of the flexible circuit.
FPCs are easy to manufacture, making them suitable for a wide range of industries and use cases. They are also available in a variety of configurations, from single-layer to double-layer. They can be made with either liquid crystal polymer (LCP) or polyimide as the insulation substrate base, allowing them to meet different requirements. Some even feature a reinforced GND design for noise resistance.
When choosing an FPC manufacturer, make sure to select one with experience in designing and producing flexible circuit boards. A good company will be able to work with you to create the best solution for your product, offering design support and advice throughout the process. They will help you select the most appropriate material for your application and ensure that the board is properly designed to account for flex movement and EMI issues. They will also offer suggestions for component placement and routing. Ultimately, this will result in superior, high-performance products that can withstand a wide range of conditions.
