    摘要: Disclosed is a printed circuit board (PCB) layout for increasing the ability of the PCB to transfer heat away from a component mounted thereon. The locations of signal vias in the PCB are selected so as to define continuous pathways in a PCB heat sink layer. This allows heat to be effectively conducted away from thermal vias connected to heat sink layer, thereby preventing PCB-mounted components from overheating.

    摘要: A method and apparatus for transferring products from one conveyor to another. Guide rails direct products into substantial contact with a push bar. The push bar pushes the products from one conveyor belt to another conveyor belt in a smooth and efficient manner, thereby significantly reducing the possibility of damaging the products.
