What is a metal stencil?
To soldering SMD-parts on the PCB a sufficient depot of solder must be available. The finish surface on the PCB has usually not enough for this. For this reason solder paste is brought on the pads. The solder paste is applied with a laser cut metal stencil.
So that the SMD-parts are not be able to slip during the soldering process on the PCB, the parts were fixed with an adhesive. The adhesive can also be applied with a laser cut metal stencil.
We offer you SMD-Metal Stencils and Glueing-Stencils. Developers we offer our economical ECO-Stencil.
The metal Stencil were made of refined steel according DIN 1.4301. There were Stencil with thicknesses of 100 μm, 120 μm, 130µm, 150 μm, 180 μm, 200 μm, 250 μm and 300 μm.
For manufacturing Stencils for self mounting systems we need once the type of the mounting system (manufacturer and type) a drawing of the perforated egde.
For positioning the Stencil on the PCB fiducials were needed. For our Stencils 4 fiducials are inclusive.
The fiducials could be manufactured in several ways. These are:
fiducial engraved: only a part of the surface will be removed
fiducial cut through: a breakthrough is made
fiducial black filled: a breakthrough is made and filled with a black lacquer
Our base prices for SMD-Metal Stencils and Glueing-Stencils contain the following achievements:
- 1000 Pads inclusive
- modification of the pads; procentual or absolute
- 4 fiducials
- inscription (engraved): 3 x 25 characters
To extend the durability of your Stencils we offer you the following options:
Edge Protection (Only for SMD stencils for a self-tensioning frame system):
For this the edges of the stencil are folded over. This minimizes the danger of injuries through sharp edges. The stability of the stencil is increased considerably.
The cutting process forms at the pad openings and pad walls an oxide coating and to the laser withdrawal side a burr. The burr will be removed within a brushing process. With several polish procedures the surface of the Metal Stencil and the pad walls will be more smoothened. Thus cleaning of the Metal Stencil will be more easily and the release behavior of the solder paste is improved.
We supply your SMD-Stencil starting from 2 working days. If you had ordered in our online shop also a PCB then we can deliver both products together if you like.
