SMT Stencile

According to many years’ practical experience, we make a deeply research in stretching technic. We adopt the materials such as environment type and high strength glue, low elongation polyester mesh and so on. we have been sincerely providing the clearer surface and ultra high precision stencil for our customers.

The Pre-stretched Frames are most commonly used in SMT stencil industry, its features are as follows:
Raw Material: AL6063, T5 Aluminum Alloy meets the standard of European RoHS.
Uniformity of Stretching Tension : +/-0.5N/cm
Tension: 34-36N/cm (measured by TETKO MAT 7-50N/CM Tension Meter)
Mesh: 24T-150um tension-stabilized and low elongation polyester mesh
Glue: Japan Epoxy A B Glue
