A vehicle body welding system includes a work station (10) for welding components of a preassembled body (12) with respect to one another.

The application of the so-called solder mask (7) ensures that only the areas intended for the soldering of parts and components come into contact with solder and that the conductor paths are protected.

The components are mutually assembled by continuous welding on the edges and by point-to-point welding at the centre.

Current manufacture technology for packaging electronic components depends exclusively on the reflow and wave soldering processes.

The dual solder layer comprises a layer of a self-assembly solder (12) disposed on a layer of a base solder (14) which is disposed on the solder pad (16) of an electrical component substrate(18).

Components are mounted to the substrate using solder.

A vehicle body welding system includes a work station (10) for welding components of a preassembled body (12) with respect to one another.

Thermally critical and uncritical components (20, 22) are inserted into the soldering paste on the printed circuit board (10).

The solder mask has critical components which include a polyhydroxyether and melamine formaldehyde.

The invention relates to shaped solder pads for automated PCB assembly, which permit a uniform distribution of the solder at a soldering point.

As the solder dries, components also become soldered.

As the solder dries, the components also become soldered.

The components are then pressed together, and a weld is made in the relief region.

A shrouded bomb is provided having components which are substantially free of weld lines and rivets.

A USB connector used to connect with a USB mother socket comprises: metal weld, connection line, base, and shaft components.
