Title: Welding machine for inner layer board
Inventor: ARAKI MASATOSHI
IPC: H05K3/46
Filed: 1999-11-19
Granted: 2002-04-21
Abstract: A set of inner layer circuit boards with prepreg exposed on the surface are laid up, and the prepreg is then melted and welded by the welding head to fix the inner layer circuit boards. In the manufacturing process of multi-layer printed circuit boards, double-sided circuit boards constituting the inner layers and prepreg are alternately laid up on a jig board, several peripheral portions are spot heated and pressured and then the prepreg is melted and welded for temporarily fixing said members which constitute the inner layers. A tape 25 is arranged between the front tip of the spot heating and pressuring welding head 17 and the work 40, so that the welding head 17 is not directly in contact with the prepreg on the surface of the work 40 to prevent the prepreg from adhering to the tip of the welding head 17 due to carbonization or softening. Further, the protrusion on the prepreg surface, formed by the tip of the welding head 17, is subjected to pressing and leveling by using a stamper 27 to prevent the reduction in the adhesion of the surface copper foil. In the case of the outer-most layer having double-sided circuit board or in the case of carbonization caused by heating of the tip of the welding head 17, the solution using tape 25 is very effective.

Abstract: A method and system for providing seamless mobile IP connectivity between mobile stations (MS) connected to a PCS network via base stations (BS) connected to base station switching centers (BSCs). The BSCs are connected to a mobile station switching station (MSC) and are configured to direct voice traffic from the MS to the MSC. A gateway router (GR) is connected between the BSCs and the Internet and each BSC is configured as an IP data node. One or more subnets are defined, each of which includes at least one BSC. Each MS is assigned a permanent IP address and associated with a home subnet. When the system detects that the MS is connected to a BSC outside of its home subnet, it is assigned a care-of address to the MS to which IP data can be forwarded. IP data from the MS is routed through the GR. IP data directed to the MS is directed to the MS's permanent IP address. If the MS is connected to a BSC outside of its home subnet, the data traffic is forwarded to the MS's care-of address. A mobile station and base station controller for use in such a network is also presented.
