Knowledge about KingshengPCBA/  flexible circuits board
 
There probably 3 classes for flexible printed circuit boards with specified uses kingshengPCBA would like elaborate and share with you here.
 
For those who may not be familiar with the flexible printed circuit boards , you have visited the right place!  They are simply printed circuit boards that have the ability to bend or flex making them wearable.
Once you understand this the name makes perfect sense and is self-explanatory.  Generally, they are uses in type of electronic device that needs to be flexible during its use.  They are separated into three separate classes each with specified uses that make them unique.
 
Class I
Class I flexible circuits are a part of every type of device that you can conjure up.  They do not need a whole of attention while wearing them because they are not exposed to rough environmental factors that usually results in the malfunction of the device.  Some examples of flexible PCB devices would be halter monitors (measures your heart rate), calorie counters, and devices that measure the number of steps you take during the time you are wearing the device.  The standard that must be met for this class is based on reliability and quality.
 
Class II
Class II flexible printed circuit boards are utilized for industrial and commercial industries.  They also are not usually exposed to tough environmental factors because of this their standards are based on quality and efficient solder joints making connections within the circuitry.  An example of where you will find a flexible PCB would be in a home automation system.  Most home systems allow you to communication with certain appliance through the internet.
 
Class III
Class III flexible printed circuit boards are used for military, aerospace, automobile and medical electronics.  Since these boards are used for such important tasks their standard requirements must meet an extremely demanding testing process before they are deemed ready to function.  The assembly process is also more involved when creating them;
Knowing when and how to connect the vias in the bend areas
Avoid connecting vias when possible
Assuring stiffeners stay in the right places
Different electrical components that are associated with it
Bending and twisting at different ratios, angles and levels
Different thermal traits
Application of the J Standard to all military devices
Thermal Shock cycling
Temperature cycling
Environmental testing
 
Flexible PCB’s are the very heart of computerized machinery, without them we would not be able to enjoy our Mobil phones,cars, games, computers, the list can go on and on ! We have come to depend on our devices, understanding the types of circuit boards your electronic gadgets have will help you appreciate those wonderful fabricators or manufacturers who share their expertise with the world so we can benefit from everything technology has to offer.  Whether you are using class one, two, or three, or any combination of the three you have experienced what todays flexible printed circuit boards have to offer us.  We excitedly continue to look forward to see what today’s technology will bring us next.
