The surface of wiring board or straight cutting welding are in the circuit board.
Further, the avoiding type stitch is conducting wire, is bent outwardly setting from top to bottom, and it is empty to form the evacuation
Between, and the surface of the end welding assist side of conducting wire.
Further, the end of the avoiding type stitch is welded in the circuit board using SMT patch mode.
A kind of card reader includes the ultra-thin magnetic head of above-mentioned built-in chip.
A kind of card swiping device includes the ultra-thin magnetic head of above-mentioned built-in chip.
The utility model has the beneficial effects that
The utility model is through the above technical solutions, sufficient avoiding space can be formd in the inside of magnetic head to avoid
Soft encapsulation chip on wiring board, allows entire wiring board to be completely disposed at the inside of magnetic head, effectively reduces the longitudinal high of magnetic head
Degree reduces volume, and installation space limitation is small, and the scope of application is wider, while soft encapsulation chip will not touch avoiding type stitch, magnetic
Head performance is more stable, more reliable, protects without special design protection structure to wiring board, and Information Security is high, and
And the ultra-thin magnetic head structure is simple, production is more easier, and is conducive to produce in enormous quantities, promote and apply.
