Advantages of Laser-cut SMT Stencils
Direct input of data through CAD files minimises the chance of errors.
High accuracy ; errors : ≤ ± 5μ m .
High smoothness of pads;roughness ≤ ± 1 μ m
Cuts accurately on stencils as thick as 0.6mm
Convenient addition of pads.
Fiducial marks can be made virtually anywhere on every side.
Fast delivery:12 hour delivery, to main cities arranged on request.
Custom-made stencil designs for customers to suit different brands of solder paste printers
Pad pitches of 150 μ m easily made.
Trapezoid pad walls help the adhesion of epoxy resin or solder paste to PCB.
Protection lip at the openings ensures epoxy resin diffuses into the openings, reducing bridging, solder bails and the cleaning of stencils. thereby decreasing waste prints.
Suitable for the strict requirements for SMT no-clean technology.
Waste prints reduced by Increased manufacturing reliability
