SMT Print tooling

Lasertec provide a range of printing tool from squeegee blades/holders to PCB Clamps and SMT Micro Stencils. With a full array of rework SMT Micro Stencils and Solder Paste printing applications we want to help operators take control of their rework needs.

Duraprint Squeegee blade / holders

Heart Sine Image For squeegee blades the main factors that must be considered is the metal type, hardness, edge profile and the coating. Each of these properties combined make the optimum squeegees blade. Lasertec uses a proprietary metal which delivers the performance characteristics. This unique metal alloy has been tested and measures over 650 on the Vickers hardness test.

More About this Service

Lasertec uses a proprietary metal which delivers the performance characteristics for durability. It has to return to the same position after each print just like a spring. Stainless steel definitely doesn’t do this, try bending a spoon !!!

Duraprint has Twice the lifetime of stainless steel !

We have Dek and MPM in stock but will make to and dimension or machine specification.

Two types of edge are available, round and stepped.

Features:

  • Longer Life
  • Lower Pressures
  • Better Flatness
  • We also still manufacture stainless steel for those wishing to stay with existing designs.

    PCB Clamps

    Heart Sine ImageMicrco SMT Stencils are tools that can be used for rework, repair of SMT and electronic components. Micro Stencil has been paramount in changing the way SMT rework is viewed and what can be done in-house. With a full array of rework SMT Micro Stencils and Solder Paste printing applications we want to help operators take control of their rework needs.

    Micro SMT Stencils

    Heart Sine ImageMicrco SMT Stencils are tools that can be used for rework, repair of SMT and electronic components. LaserTec offers a complete range of precision laser stainless steel micro stencils allowing for the accurate and precise volume deposition of solder paste to the circuit board pads for reworking BGAs.

    BGA Reballing Fixtures

    This method involves component-specific stencils and tooling to allow paste or flux to be printed and loose solder balls to be located in the correct position before being reflowed – again in a controlled environment. Solder balls of different sizes and compositions are available from us or your solder paste manufacturer.
    The diagrams show the process being used with printed solder paste and non-melt, high-temperature solder balls.
    Stencil printing. Figure 1 shows solder flux gel being printed onto the component. The part is held in a fixture and the solder paste is manually applied using a LaserTec mini stencil.
    Solder ball application. In the second stage (Figure 2), the flux gel printing stencil has been removed and replaced with a larger stencil that will dictate the position of each solder ball. Loose solder balls are then poured onto this stencil and fall ( or brushed ) into their intended positions above each printed pad. When all the apertures have been filled, any excess solder balls can be brushed off or poured off the stencil.
    Reflow. After all of the balls have been placed, the component is ready for reflow. The method shown in Figure 3 completely removes the stencil and uses forced convection from above to reflow the solder balls.
    The reballed part is removed from the fixture and is ready to be attached to the PCB as a normal component.
    This method is preferred over the solder paste rebumping method as the size and shape of the balls can be controlled

    All of these technologies and process guides are avilable from any of our staff just give us a call
