The overlap pad 1, pad (except for the surface mounting pad) overlap, which means the vias overlap, the drill bit will be broken because of multiple drilling in the same area during the drilling process, then resulting in via damage. 2, 2 vias overlap in multilayer flexible PCB board, such as one via is isolation [...]
Because of the light and thin characteristics, it requires special of the equipment and processing method for the surface finishing of the flex board, regarding to the production of flex board, surface cleaning is a key step, because it requires not only the surface Dimensional stability of the flex PCB board but also the dimensional stability [...]
Over the last decade, flexible circuits, or flex PCBs, have emerged as one of the fastest-establishing market segments for interconnection products. Part of the reason that PCB manufacturing is up so much in terms of growth is because they are commonly used within a large range of quotidian electronic products in addition to many [...]

Full Product Lines of Flexible Circuits We provide with components procurement, flex PCB manufacturing, [...]
The principles for designing a high quality, manufactural flexible printed board are as follows (Minco Application Aid 24): 1) First, it is desirable to have some valuable literature aimed at applied research. The most useful document is the IPC standard or the MIL standard. For example, IPC-6013 and IPC-2223 or MIL-P-50884 can be used if [...]
Printed circuit board specifications are more complexed, many types of products, generally classify by PCB layers, flexibilities and materials. According to the number of layers can be divided into: single-sided, double-sided and multi-layer; according to flexibility can be divided into rigid printed circuit boards and flexible printed circuit boards; by material can be divided [...]
Nowadays, if outsource the FPC in circuit flexible manufacturer, normally for simple FPC (1 layer, 2 layer, 4 layer board) generally 3-5 working days lead time, for complex circuit board (6 layers, 8 layers and above) 6~15 Working days. The engineers are mainly responsible for the design work, outsource processing is generally issued by [...]
First, the advantages Flexible A significant advantage of using flexible PCBs is that they can be more easily routed and assembled in three-dimensional space, and can be crimped or folded. As long as the radius of curvature within the allowable range, can withstand thousands or ten thousand times of usage without damage. Reduce the [...]
According to the placement accuracy requirements and components of the different types and quantities, the current commonly used flexible PCB assembly solutions are as follows: Option 1, simple mounting on a single side FPC Scope of application Component types: mainly resistors and capacitors, etc. Components quantity: Each piece of FPC need to mount a [...]
Flexible circuits PCB have become functionally pivotal and a fast growing electronic goods technology. These circuits function as connectors in most applications where space saving, construction constraints and flexibility limit service capability of hand wiring or rigid circuit boards. The substrate that is used in LCD fabrications is glass. If thin, a flexible metal or [...]
