Laser Stencil Masks have a number of distinct advantages, which make them ideal, for printing heavy, solder pastes and epoxy die-attachement materials:

Excellent paste transfer 100% open area

Excellent solvent resistance

Outstanding durability if properly handled

Our unique mesh-support system helps to maintain optimum tension on the metal stencil.

The mesh will flex enough to allow for printing in the off - contact as will as on contact mode.

In most cases, a 25mm minimum border of mesh will be provided around the perimeter of the metal stencil.

More border must be provided when off - contact printing is to be utilised.

Laser stencil masks from MCI are available on our standard aluminium frames and on all frames provided by customers.
