Abstract
It is known from the prior art that holes in a workpiece are filled completely with a solder powder, which leads especially in the case of large holes to the formation of cracks within the solder due to the large volume filled in once the solder cools off after soldering. The invention provides a method for closing a recess of a workpiece, which allows closing an opening of a recess without the risk of crack formation, by using only a solder film for closing the recess. The solder film has a content of non-melting material and therefore is substantially less prone to form cracks.
