Abstract
The present invention features an improvement in the construction and manufacturing of small peripheral cartridges which plug into exterior slots of computer systems such as PCMCIA cards. The metal cover of a snap-together PCMCIA card is typically tack welded at its seams An inexpensive and highly accurate welding technique is presented for performing this welding operation. The inventive welding technique may be used without risk of damage to highly sensitive electronic components. The lap joint seam formed using the techniques exhibits the strength and stiffness characteristics that allow the size of welded seams to be minimized thereby also reducing the risk of burn-through or other damage to the cards during manufacturing.
