Flexible PCB


Flexible PCB develop and receives a wide range of applications owing to its remarkable advantages including flexible structure, small volume and light weight, compatible with electronics development trend towards miniaturization. Apart from static flexibility, flexible PCB is also capable of implementing dynamic flexibility, curling and folding. Capable of expanding towards 3D space, flexible PCB improves freedom degree of circuit design and mechanical design. Moreover, tracing can be done on X, Y and Z surfaces with connection points decreasing, which can both decrease machine work and assembly errors and dramatically improve reliability and stability of the whole system applied by electronic devices. As a result, flexible PCBs are widely applied in fields such as computers, communicators, instrument, healthcare devices, military and aerospace etc. Furthermore, new application fields of flexible PCB including wireless floating head, repeaters, digital cameras, cell phones and flat panel display and HDI PCB dramatically lead flexible PCB to rapidly flourish and account for an increasing portion of the whole PCB industry. 


In accordance with Copper layers, flexible PCBs can be classified into the following categories: 


a. Single-side flexible PCB, which features a simple structure and is easily fabricated. 


b. Double-side flexible PCB, which features a far more complicated structure than single-side flexible PCB, calling for more control difficulties. 


c. Multi-layer flexible PCB, which features a more complicated structure than 2-layer flexible PCB and its fabrication quality is more difficult to control. 


d. Single-side rigid-flex PCB 


e. Double-side rigid-flex PCB 


f. Multi-layer rigid-flex PCB 


Single-side rigid-flex PCB, double-side rigid-flex PCB and multi-layer rigid-flex PCB are more difficultly fabricated than the first three types of flexible PCBs, featuring far more complex structures. 


Flexible PCB Assembly


Flex PCB assembly has no much difference than rigid PCB, the most differences is you have to fix the flex PCB boards well when do the SMT assembly since the FPC boards are very thin and could move or curve or warping very easily during the assembly. Normally, it's very same as rigid PCB when do single sided FPCB Assembly. But when you need do both sides FPCB assembly, you'd better to make an assembly fixture for the flex PCB assembly job to get the good quality. 


Flexible PCB Assembly Properties 


a. From Flexible PCB to Rigid PCB Flexible PCB tends to get deformed due to its light weight and thinness, incapable of being directly assembled on SMT manufacturing line like rigid PCB. Thus, to successfully implement assembly on flexible PCB, it has to be fixed on rigid carrier or tray so that it can be dealt with like rigid PCB. Flatness, accuracy of positioning and consistency of board carrier play a key role in completing product quality, which is where flexible PCB assembly focuses on. 


b. Low Density Up to now, because flexible PCB features higher cost than rigid PCB, majority of flexible PCBs are only applied for connections between modules with different functions based on product cost concern. As a result, the number of components ready to be assembled on flexible PCB is relatively low with low assembly density. Generally speaking, the number of components is within 50 and some boards contain only two connectors. 


c. Large Number of Panels Flexible PCB is mainly used in miniaturized electronic products such as cell phones and digital cameras so that the area of single board is small. Furthermore, the number of components assembled on single board is quite low, so in order to improve assembly efficiency, panels are usually applied for assembly after which they will be separated through punching. 


d. Wide Applications of Auxiliary Fixutres during Assembly Process Lots of auxiliary fixtures participate in flexible PCB assembly due to its deformation and damage features, including flexible PCB baking fixture, board carrying tray, electrical test fixtures, function test fixtures and cutting fixtures. 


e. High Requirement on Product Quality Since flexible PCB is usually applied in the environment calling for repeating bending and control accuracy, components assembled on flexible PCB have to be able to meet the demands of their application environment. As a result, flexible PCB calls for higher requirement in terms of cleanliness, anti-static precautions and soldering reliability than rigid PCB. In addition, owing to prevalence and acceptance of lead-free manufacturing technologies, flexible PCB assembly has to face up with some technical challenges. 


f. High Assembly Cost Compared with rigid PCB assembly, flexible PCB assembly leads to high overall cost, which is especially true in the starting phase as a result of wide range of applications of fixtures, long manufacturing period, low rate of equipment utilization, higher demands of accessories and staff and higher requirement on manufacturing environment and product quality. 


The application range becomes increasingly larger as electronic products develop and flexible PCB assembly technology constantly improves and become optimized with manufacturing and assembly cost gradually decreasing, which will thereafter lead flexible PCB to step further into wider range of applications.
