About this member
The application of the relevant amounts of solder for the components is implemented primarily through the correct selection of the required stencil thickness. This selection is influenced by the basic design rules applicable to the components. A final decision, however, is always in the hands of experienced manufacturing engineers.
Normally, different volumes of the paste can be applied due to the professional design adjustments of the pad structure.
Alternatively stepped stencils can be used. In this case the required solder paste volumes are regulated by partial adjustment of the stencil thickness.
Precision stencils for wafer bumping, BGA, LTCC, Solar
Precision plates above 50µm thick are used for wafer bump stencils. These are processed tension free and to high accuracy in climate controlled conditions with highly accurate laser systems.

Laser micro cutting, SMD stencils, laser marking, laser engraving: for more than 32 years KMLT® has been the specialist for reliable contract manufacturing in the demanding field of precise laser micro processing.

These place particularly high demands on the laser equipment and the engineer’s technical know-how.
It is dependent here upon placing the least thermal demand on the material. The results are deformation free stencils with up to several hundred thousand pads.
Special demands on the stencil production need to be considered for semiconductor and hybrid technologies.
By using these precision stencils different substances can be applied in print procedures.
Stencil for solder paste printing for a BGA component
In the case of printing using BGA/μBGA, LTCC, Solar, flip chip technologies and for particular high density stencils, metal foils are used with a material thickness from 20μm.
The production of these stencils, tension free, plane and with very high accuracy, places particularly high demands on our production technology and know-how.
As is true for the wafer bump stencils, the material must be minimally thermally affected in order to produce deformation free stencils with sometimes more than one hundred thousand openings.
