Introduction for SMT stencil types

1.FRAMED SMT STENCILS

Framed SMT stencils, also known as glue-in stencils, feature a permanent stencil frame. A mesh border keeps the stencil foil stretched taut for optimum accuracy. These stencils have benefits such as:

--Double-bonding for high-wear applications: Sturdy engineering resists intense use.

--Superior print performance: Smooth and taut aperture design creates accurate prints.

--Non-fading fiducial (marking) results: Screen-printing process makes long-lasting fiducial layouts.

--Ability to withstand numerous uses: Permanent mounting offers high levels of integrity.

--Availability for immediate use with an SMT printer: Preassembled product works in a screen printer right away.

Because of its durable engineering, a framed SMT stencil suits high-volume printing applications. We recommend this product for production runs that require long-term use. Consider choosing a framed stencil when you plan to assemble a large number of PCBs over an extended period.

2.UNFRAMED SMT STENCILS

Unframed SMT stencils consist of stainless steel foil without a permanent frame. They fit into reusable frames and can detach from them at any time. The benefits of using frameless stencils include:

--Cost-effective price: Frameless stencils results in a significant price reduction from a framed design.

--Reduced storage space: Compact size saves on space needed for storage.

--Lower environmental impact: Use of fewer materials suits eco-friendly production methods.

--Excellent print performance: High-quality engineering promotes top performance throughout stencil’s lifespan.

--Compatible with screen printing and hand-printing: Versatile format allows for printing with a machine or squeegee.

Since frameless stencils last for a fair amount of time, they fit short-term applications. We recommend them for short production runs or prototype circuit boards. Choose an unframed stencil for lower volumes of PCBs produced in a short period.

3.PROTOTYPE STENCILS

A prototype stencil features the design you specify using a CAD or Gerber file. The user places it over their PCB and uses it to print the design by hand. Prototype stencils offer these benefits:

--Precise hand-printing: Alternative to hand soldering reduces the potential for errors.

--Reduced prototype assembly time: Quick alignment and printing increase efficiency.

--Eliminated need to use a machine: Hand-printing application requires no machine setup.

--Ultimate cost-effectiveness: Efficient design results in affordable price.

--Ease of use: Alignment tools allow for an easy-to-understand stencil printing process.

Prototype PCB stencils live up to their names — they suit prototype printing SMT applications. We recommend using them to test out your PCB design due to their affordability and ease of use. Add a prototype stencil to your order if you want to print a fast test product before creating a permanent design.
