SMT Stencils and Micro-cut Parts

Cutting-edge solutions from the stencil laser cutting pioneer

Stencils, also called "SMT stencils", play a key role in the transfer of accurate amounts of solder paste to correct positions on bare circuit boards ready for assembly. Based on its extensive stencil cutting experience, LPKF provides a flexible laser process that you can use to manufacture precision parts to your specific requirements.

The first choice for SMT stencil manufacturers

Stencil manufacturers depend on efficient production processes. This means a perfect combination of high-speed, top-level-accuracy and trusted repeatability. LPKF StencilLaser technology itself plays a key role here. But there is more: One of the most important points is a deep understanding of the stencil application. Our LPKF experts for stencil cutting are happy to help you with your projects.

Optimum results

Stencil apertures with defined properties are essential for perfect solder printing results. LPKF StencilLasers are capable of cutting sheets from 20 μm up to 600 μm. The pictures below show exact geometries with nearly burr-free stainless steel. Steep or tapered sidewalls with equally smooth surfaces, as displayed in the pictures below, result in optimum paste release.

Step stencils

Step stencils allow the exact adjustment of the solder paste volume on differently sized contact surfaces. A step stencil is a special SMD stencil shape that features local recesses (step-down) or bumps (step-up). This allows assembly of a circuit board with semiconductor components having little pitch or with rugged connection components in one work step.

Commitment and innovation

LPKF has been introducing innovations in electronics manufacturing for more than 30 years. With the LPKF StencilLaser a new form of electronics manufacturing in 1992 was established. Even today  we continue to be the gloabal market leader in SMD stencil manufacturing.
Investment in capital equipment is a big deal. LPKF StencilLaser systems are designed from the ground up to be safe and successful. The LPKF stencil cutting systems enable the stencil business to provide the highest performance, quality and reliability to their clients.
LPKF not only supplies the laser systems but also offers expert service and support around the clock. The supplied software meets the requirements of stencil technology. Our ambition is to offer the most productive and precise equipment – at the cutting edge of development. That is what our engineers and technicians are committed to. Performing “Made in Germany” at its best.

Micro-cut parts made from thin metal foils

Deriving from the stencil cutting knowledge, micro-cutting of parts and stainless steel membranes is also possible. The detail and accuracy are amazing.

As many applications continue to shrink, accuracy and micro-cutting are becoming manufacturing necessities.

The laser separates out the desired components from metal foils up to one millimeter in thickness. Depending on what is asked for, the StencilLaser can either perform fusion cutting or cut out the contours by vaporizing the metal multiple times along the cutting contour. This makes it possible to produce even complex contours – such as tabs that are only a few micrometers thick – without distortion.

Extended application option

The LPKF flatbed frame features a stable support grid consisting of a number of pointed support posts. The metal sheets are laid on the grid for laser cutting. Thick sheets in particular can be laid flat, helping the laser to remain focused on the material surface across the entire working area

The StencilLaser product line

By far the most productive SMT stencil cutting system on the market today.

The LPKF StencilLaser P 6060 is a state-of-the-art laser system for manufacturing SMT stencils.

 Options and accessories


The performance capabilities of the LPKF StencilLasers can be extended through the addition of accessories and options. High-grade materials and precision manufacturing ensure the high reliability and longevity of all add-ons. Please don't hesitate to contact us, to discuss your requirements.
StencilCheck Software for Performing Quality Checks on SMT Stencils

LPKF StencilCheck inspects the quality of SMT stencils. The software produces an optical scan of the stencil using a conventional PC scanner, and compares it with the production data. Any discrepancies are graphically shown on the screen. All of the test results are compiled in a report which is available for tracing to support seamless quality management.

SMT Stencil Stretching Frame

The LPKF ZelFlex Z4P is a unique patented pneumatic four-sided stretching frame for quick and uniform clamping of SMT metal stencils.
ZelFlex Protect is a high-quality reusable stencil frame system that saves time and money. Frameless stencils can be mounted directly into the frame system without the need for glue or mesh. Uniform tension is applied through a unique air bladder system that provides continuous tension in all directions without requiring a permanent air connection.
Traditional framed stencils have many disadvantages. The mesh relaxes and the tension changes; each stencil is mounted at a different angle to the frame; the frame takes up a significant amount of storage space; and old-style frames use epoxy and must be recycled. The ZelFlex Protect Reusable Stencil Frame system is a cost-effective and environmentally friendly alternative to glued stencil frames.

Dust Extraction

The LPKF dust extraction with absolute filter ensures a clean workspace.

Flatbed Laser Cutting Frame

The LPKF flatbed frame features a stable support grid consisting of a number of pointed support posts. The metal sheets are laid on the grid for laser cutting. Thick sheets in particular can be laid flat, helping the laser to remain focused on the material surface across the entire working area.
