<p>A shielding can for a printed circuit board comprise a frame with side walls and a lid with means to increase flexibility of the lid. The flexibility means are slits on the sides of the lid. These slits enable a flexible contraction, when soldering the shielding can onto the printed circuit board. The invention also includes a method for mounting the shielding can onto printed circuit boards. The shielding can is placed onto the printed circuit board and heated slowly to melt the solder paste to solder the shielding can to the printed circuit board. The heating phase is followed by a fast cooling phase, and the flexible means (the slits on the shielding can) reduces the internal stress, which occurs when the shielding can is exposed to different temperatures at the same time, without any permanent deformations. <IMAGE></p> |
