  • Publication number: 20200176940
    Abstract: A crimping apparatus comprising a press module connected with a pressing mold, a translation module, and a pressure control module is disclosed. The press module generates an action force on the pressing mold through a fluid. The translation module is coupled to the press module for driving the press module to move toward a flexible printed circuit having two isolated circuit layers such that one circuit layer is pressed to crimp to the other circuit layer, wherein the pressure control module adjusts the pressure within the press module to maintain a constant force on the pressing mold whereby the pressing mold can generate a constant stress acting on the flexible printed circuit during the crimping process. In addition, the crimping apparatus can be adapted in a roll-to-roll process for crimping two isolated circuit layers of each flexible printed circuit unit arranged on the roll.

  • Patent number: 10650961
    Abstract: An apparatus of coupled inductors includes a first coil and a second coil arranged in a way that an inter-coil capacitance between the first coil and the second coil can keep electromotive forces induced by a first inductance of the first coil and a second inductance of the second coil about the same. As the current bypasses an unbalanced parasitic capacitor, a compensation capacitor disposed between the two coils can compensate the inter-coil capacitance of the parasitic capacitor. The apparatus of coupled inductors implemented with a specific coil arrangement or disposed with the compensation capacitor can keep the EMFs induced over the two inductances equal in amplitude, which prevents both the differential-mode and common-mode interference from being converted, improving the characteristics of mode conversion and is suitable to be utilized in a PoE system or the like.
