Laser Stencil

Apart from all types of Printed Circuit Boards (PCBs) such as Prototype PCB, Standard PCB, Aluminum PCB, HDI PCB, Flex PCB, Flex-Rigid PCB, High-Frequency PCB, Thick copper PCB, High-Tg PCB and Halogen-Free PCB, PCBCart also manufactures solder paste stencils to meet Surface Mount Technology (SMT) requirements.

Stencils, also called SMT stencils, play a key role in transferring accurate amount of solder paste to correct positions on bare circuit boards ready for assembly. In other words, stencils can fast and efficiently ensure the most accurate solder paste amount and optimal electrical connection. With solder stencils, it is possible to use metal squeegee blades to apply solder paste easily over the openings on PCBs and make stencil to be well aligned with the surface of the advanced circuit board.

According to SMT stencil manufacturing technologies, we provide two types of stencils: laser-cut stencils and chemical-etch stencils.

Laser-cut stencils

The openings are lasered on 100% stainless steel. Generally speaking, this kind of stencil can be produced with high quality and a high degree of precision within a short time.
• Advantages: high accuracy; barely influenced by objective elements; trapezoid opening beneficial for demoulding; suitable for accurate cutting; reasonable price;
• Disadvantages: relative low manufacturing speed.

Chemical-etch stencil

The openings are etched into the metal using acid. Usually this kind of stencil offers better protection on material temper and hardness.
• Advantages: one-time formation; relatively high manufacturing speed; low cost;
• Disadvantages: tending to form sand clock shape or large openings; numerous manufacturing stages and accumulating errors; unsuitable for fine pitch stencils; bad for environmental protection.

How to Determine Stencil Size?

Stencil size is determined by PCB size. For framed stencil, its Width = width of PCB + 100mm while its Length = length of PCB + 100mm. When comes to frameless stencil, its Width = width of PCB + 200mm while its Length = length of PCB + 200mm

For example, if one circuit board size is 50*50mm, then the size of its frameless stencil should be around 150*150mm and the size of its framed stencil should be around 250*250 mm.

How to Order Stencils

Here at PCBCart, you can order stencil alone or buy together with PCBs.

Purchase stencil together with PCBs. Enter Standard PCB Quote page or Prototype PCB Quote page, fill in your custom PCB spec, then check the Laser Stencil option at the bottom part, and enter your required stencil parameters. As soon as these gaps end up being filled, the stencil will be contained in your order list.
