Hello, readers welcome to the new tutorial. Here we will discuss What is Polyimide PCB Board. PCB board is now a very basic and important portion of any electronic projects and devices that are normally used. It comes with different types and categories and features that are necessary for making any project and module. There is a non-conductive substrate material used PCB and over which copper layers are assembled to make circuits and traces of components that are linked to make circuits of projects.
According to the use and features of the PCB board, there are single and double layers of PCB designed and created. There are some applications where different numbers of layers of boards can be created.
There are many kinds of PCB boards The creation of your project relies on the excellence of the PCB board. If there is no good feature PCB you are not using your tasks will not work in an appropriate technique. To get a decent feature PCB there must be reliable and trustable PCB providers. Many PCB producers are working in this creation but the most dependable and highly trustable PCB provider is PCBWAY which offers high-quality PCB boards at a reasonable price.
The chief resolution of PCBWAY is to offer high quality, less expensive, and fast delivery to their clients.
In the characteristic of less-priced electronic schemes, it is the first PCB provider that offers PCB prototyping service at $5/10pcs.
If you use coupons after getting new registration the price will be reduced to zero dollars.
They offer ten dollars stencil and a comparable price for different solder mask colors. The order delivery time is normally two to three days.
History of Polyimide PCB
- First-time polyimide PCB boards were created in 1908 and then about 1955Â its mass production was increased to a high level.
- The common color combinations that is used to make PCB boards is yellow, orange, and ambers which have a high value of flexible behavior through this module.
- Their temperature range for operation is about four to five hundred.
- These boards offer numerous categories such as coated surfaces, fibers portion sheets of films.
What is a Polyimide PCB Board
- To give a detailed overview of Polyimide PCB boards first we discuss the term polyimide.
- The term polyimide is a combination of two words first one is poly which means polymers and the second one is imide which means monomers. Simply, polyimide is a group of polymers.
- Polymers are created through use of different processes such as synthetic. These artificially made polyimide materials are used to make PCBs called polyimide PCB boards.
- The polyimide used to make PCB gets through the use of different types of imides. Use process of creation is called polymerizing and the resultant is used to make PCB boards.
Materials of Polyimide PCB
- Polyimide PCB boards are created through the use of imide monomers. There are different types of material created through natural and synthetic processes are used for PCB creation.
- In the case of natural polyamide, there is silk and wool are used while to make PCB boards there is synthetically made polyamide is used.
- The main process used for the creation of this board are bis maleimides and maleic anhydride.
- To get good results there are certain chemicals are employed that are explained here.
Pure Polyimides:
- This category of polyimide is called second-generation polyimide and was created in the absence of brominated flame retardants.
Filled Polyimide
- This material comprises of polyimide and fillers. Fillers are used to decrease the resin shrinkage process and polyimide gives flexible behavior to the board.
Third Generation Polyimide
- This material offered resistance for the flame to the board helpful for damaging wires if the fire burn
Features of Polyimide PCB
- The main features offered by this board are listed here with the details.
Durability
- They come of with features that have high value of resistance when the force is applied to it. Such design it has that there is physical structure is retained for a long time without breaking and damaging so prefer for strict conditions.
Chemical Resistance
- This board shows the high-level resistance to different corrosion substances when applied to it and makes it effective to use on.
Stability for High Temperature
- There is best features that can bear the large value of temperature applied and has the ability to manage the two sixty degrees of temperature. The high value of temperatures applied during the manufacturing process can also handle by this board.
Flexible Nature
- It shows the high value of flexibility nature.
Applications of Polyimide PCB
- The main applications of the Polyimide PCB board are listed here with the details.
Military Devices
- Due to high flexible nature of thermal ability and reliability, it is mostly used in different appliances and devices of military use.
Medical devices
- As this board is flexible and different devices used in medical need flexibility such as imaging process prosthetics so it is employed.
Smartphones
- The boards of smartphones tablets and mobile phones are designed through these boards that need a certain value of flexibility to maintain the construction of components
Automobile Industry
- Polyimide board are used in different parts of vehicles since it can manage the heating process in the devices.
Differences Between FR4 and Polyimide PCB
- The detailed comparison between FR4 and Polyimide PCB is discussed in detail in the below table. That is discussing the different features based on their working and construction
| Features | Polyimide PCB | RF4 |
| Chemical Resistance | It offered good resistance against for applied chemical materials | It offered good resistance against applied chemical materials |
| Thermal Cycling Process | Its thermal cycling process is better than the FR4 | Its thermal cycling process is good but less than FR4 |
| Temperatures | it can bear the minus two hundred to plus three hundred centigrade | Its operating temperature range is minus fifty to one hundred ten centigrade |
| Durable Natures | Its durability is very impressive and can bear the high value of stress applied to it | It has less durable features but is not bad |
| Tensile Strenght | Its tensile strength is 231 MPA | Tensile strength is 70MPA |

That is all about the Polyimide PCB Board. I have covered the all parameter related to this board. If you have any further query ask in the comments. Thanks for reading have a good day see you in next post
