Abstract: A bonding pad structure is disclosed, which is composed of two bonding pad units that are symmetrically disposed with respect to an axial line. Each bonding pad units is further composed of at least two bonding pads, i.e. each bonding pad unit is composed of at least one first bonding pad and at least one second bonding pad. In an embodiment, the first bonding pad is arranged next to the axial line and the second bonding pad is arranged at a side of the corresponding first bonding pad away from the axial line while enabling the first bonding pad and the corresponding second bonding pad to be interconnected to each other by a first neck portion. Thereby, a plurality of solder areas of different sizes can be formed by the interconnecting of the at least two bonding pad units that can be used for soldering electronic components of different sizes.

Abstract: A soldering pad layout for flexible printed circuit board (PCB) is disclosed, which comprises: a top substrate; a middle substrate; and a bottom substrate, being arranged by stacking one over the other successively in parallel. In an exemplary embodiment, there are at least a top routing layer, being sandwiched between the top substrate and the middle substrate, and at least a bottom routing layer, being sandwiched between the middle substrate and the bottom substrate. With the aforesaid soldering pad layout, not only circuit breakage caused by stress concentration on a bended flexible printed circuit board can be prevented, but also the routing path required on the PCB can be shortened and the amount of space for laying out parts on the PCB can be reduced.

Abstract: A flexible printed circuitboard structure is disclosed, which comprises: a flexible printed circuitboard (FPC), having at least a soldering pad and at least a solder pasted pad area formed thereon; wherein, by using the extending of a side of the at least one solder pasted pad area as the base line, a bending line is formed on the FPC in a manner that it is prevented from passing through the at least one soldering pad and is disposed at a specific distance away from the periphery of the same. By the configuration of the solder pasted pad area to defined the bending line on the FPC, the bending stress problems caused when the FPC is being bended, such as solder crack and broken circuit, etc., can be prevented.

Abstract: An anti-breakage structure for a transmitting end of flexible printed circuitboard (FPC) is disclosed, which comprises at least a via hole, being formed on the FPC at a position corresponding to each pin of the transmitting end while enabling the at least one via hole formed on any two neighboring pins to be arranged in a staggered manner without being align on the same line. As the via holes formed on any two neighboring pins of the FPC's transmitting end are not aligned with each other but are scattered so that the area where stress is likely to concentrate is increased when the FPC is subjected to an external force, stresses can be distributed evenly through the whole transmitting end of the FPC without forming any specific stress concentration area.
