The optimal design of stencils plays a key role in ensuring good productivity and quality in our production processes.
The control of the sizes of the apertures, the thickness of the template and the exact generation of fiduciaries / markers / are directly related to the volume, the correct positioning and printing of the paste during the assembly operations. The correct design of the template, combined with quality production, significantly affects the productivity and quality of installation.
Laser cutting is a fast process that allows us to offer a standard 2-3 day production, with the ability to send faster, if necessary, and without compromising the accuracy or quality of the template. The templates are made of stainless steel, carefully selected for smoothness and uniform thickness – important qualities of the precision template. The laser cutting process produces holes with a trapezoidal cross section, which allows excellent release of paste in production. The laser cutting technology is unique in that by adjusting the intensity of the laser during production, we can create extremely accurate and correct holes in the templates.

Information required for processing inquiries in MOST ELECTRONICS regarding the design and delivery of metal templates / stencils:

• Complete Gerber files in mm or mils.
• When the boards are delivered in panel-panelized gerber files.
• Type and thickness of the material – 80um to 300um.

PCB design includes:

• preparation of files for automatic drilling
• cutting
• solder mask / color – green (standard), red, blue, black, white/
• white seal
• if necessary, files for making a stencil, automatic saturation,
• panelization of the finished project
• generate Gerber and Drill files.

Upon completion of the project, the client receives all the necessary files with complete technical documentation on the printed circuit board and a prototype of the product, if such is agreed upon the assignment of the project. The finished files and projects are the property of the client and we do not distribute them and provide them to third parties under any pretext.

For the production and delivery of bare printed circuit boards we use subcontractors approved by us, which offer an excellent ratio of quality, delivery times and price. All printed circuit boards are delivered with passed internal circuit electrical test.
