When it comes to PCBs, there are a whole lot of PCB materials that are used to make these PCBs depending of course upon the application and the environment in which it will be used. Some of the popular materials include:
Polyimide is a high-performing polymer, which is made up of imide monomers. Polyimide occurs naturally and can also be manufactured synthetically. Polyimides are broadly of three types:
The most common way of production of polyimides is through a reaction between dianhydride and diamine.
Polyimides are known for their heat and electrical resistance as well as their high mechanical strength. They are ideal for use in flex and flex/rigid circuit boards.
Below are some features of polyimide that make them extremely useful in certain PCB applications:
On account of high resistance to physical stress, Polyimide PCBs are extremely durable. They retain their shapes even in extremely harsh environments.
Polyimide PCBs can withstand a wide range of temperatures. In fact they are known to support operations with temperatures up to 260℃.
The other advantage with them is that they can resist any thermal damage during production or repair.
Known for their extreme flexibility, they are suited for use in rigid-flex as well as flexible printed circuit boards.
Polyimides are also known for their chemical stability. If they are exposed to corrosive materials, they do not show any adverse effects. In applications where the PCBs are likely to be exposed to chemicals, Polyimide works best.
Known for its tensile strength, polyimide PCBs can support high load without any fracture. Also, when it comes to warping, Polyimide PCBs are resilient. They are therefore widely used in applications where physical strength and durability are a must have.
Some of the other important features of Polyimide PCBs include:
Some of the differences between Polyimide & FR4 PCBs include:
Little surprise then that Polyimide PCBs are used in a wide variety of PCB industrial solutions, including but not limited to:
Polyimide PCBs find application in:
Polyimide PCBs work as a very good alternative to FR4 printed circuit boards on account of the features that Polyimide PCBs offer. These mainly include flexibility, thermal resistance, quality and reliability.
