- 2 LAYER fpc circuit boardDetail InformationFlexible Printed Circuit Board (abbr. FPCB) .Features：FPCB is minimization , slimness , high technology for whole digital products which are getting smaller , slimmer.Compare with the rigid printed circuit board , FPCB has the following advantages :① light, thin, short, small, flexible structure, can be bent, curled, folded, and three-dimensional assembly, adapter can replace a lot of parts, easy to use maximum available space, making electronic products become more slim in appearance, widely used has a small,lightweight and mobile requirements of all kinds of electronic products ;② high heat resistance, can produce higher density and finer pitch products to meet the high density interconnect between the components and the high stability requirements, so that a larger increase the quality of the signal output ;③ can be wound transfer roller processing methods (Roll-to-Roll), easily automated, mass production, improve production efficiency.Technology：Flexible electronic assemblies may be manufactured using identical components used for rigid printed circuit boards, allowing the board to conform to a desired shape, or to flex during its use.Applications：Computer,communication equipment,precise apparatus and instrument,router and etc.Single-sided flexible pcbSingle-sided flexible circuits have a single conductor layer made of either a metal or conductive (metal filled) polymer on a flexible dielectric film. Component termination features are accessible only from one side. Holes may be formed in the base film to allow component leads to pass through for interconnection, normally by soldering. Single sided flex circuits can be fabricated with or without such protective coatings as cover layers or cover coats, however the use of a protective coating over circuits is the most common practice. The development of surface mounted devices on sputtered conductive films has enabled the production of transparent LED Films, which is used in LED Glass but also in flexible automotive lighting composites.Double-sided flexible pcbDouble-sided flex circuits are flex circuits having two conductor layers. These flex circuits can be fabricated with or without plated through holes, though the plated through hole variation is much more common. When constructed without plated through holes and connection features are accessed from one side only, the circuit is defined as a "Type V (5)" according to military specifications. It is not a common practice but it is an option. Because of the plated through hole, terminations for electronic components are provided for on both sides of the circuit, thus allowing components to be placed on either side. Depending on design requirements, double-sided flex circuits can be fabricated with protective coverlayers on one, both or neither side of the completed circuit but are most commonly produced with the protective layer on both sides. One major advantage of this type of substrate is that it allows crossover connections to be made very easy. Many single sided circuits are built on a double sided substrate just because they have one of two crossover connections. An example of this use is the circuit connecting a mousepad to the motherboard of a laptop. All connections on that circuit are located on only one side of the substrate, except a very small crossover connection which uses the second side of the substrateProduct DisplayNAVIGATION
