PCB Stencil Design | How to Balance the Speed and Quality of PCB Stencil Design

Time:2022-05-27Views:399

Introduction: PCB Stencil design is the core process of SMT (Surface mounting technology). Stencil’s quality concerns 70% PCB manufacturing process, including silkscreen printing, SPI, SMT, reflow welding, etc.

Are you still troubled by the error-prone stencil design? Or have you ever encountered confusion about stencil design after the senior engineer resigned? Or you might have found that the stencil designed by different personnel varies in quality. Actually these situations are common in the industry.

Following the trend of intelligent manufacturing, you need to explore a new approach to design your stencil. How? Yes, to introduce the intelligent software tool.

Vayo-Stencil Designer is an intelligent software to automate the stencil design, developed by Vayo Technology, a global provider of all-in-one NPI solutions. How could this software help you speed the stencil design while to ensure the quality?

Stencil Aperture Library

Vayo-Stencil Designer is equipped with an aperture library, which allows the company to standardize the stencil design and prevent quality varying due to change of designers. With the aperture library, the software could learn the high-quality stencil design or the stencil aperture of former projects, then store these aperture into the library for future use, which could save much time for stencil design when a new project arrives.

The learning process is also a know-how digitalization process. By traditional method, stencil design know-how is only retained as engineers’ personal experience, hard to pass forward. Once these experienced engineers resigned, it would be a great loss for the company. By digitalizing the stencil design know-how, even a fresh designer is able to design the high-quality stencil with the software.

The standard and requirements of stencil are also critical factors affecting the stencil quality. Different process engineers prepare different requirements and stencil manufacturers may misunderstand these requirements, thus providing unqualified stencils. Using the stencil aperture library, process engineers don’t have to spend a long time preparing the requirements anymore and the understanding variation by manufacturers could also be reduced.

 

Stencil Design Automation

Based on the high-quality aperture library, stencil design becomes a time-saving job. When a new product project arrives, the software would intelligently assign the aperture matched with the new project from the aperture library. You don’t have to prepare requirements and communicates with stencil fabricators like before. The design would be completed in minutes.

For those packages not stored in the library, Stencil Designer software also provides rich aperture patterns. Process engineers could selects appropriate patterns aligned with the package and modify some parameter settings, then a new aperture design is completed.

 

Automatic Stencil Optimization

Besides the high-quality aperture library, Vayo-Stencil Designer also come with powerful functionality to automatically optimize the designed aperture. The optimization items include: via avoiding, step area, cooling pads, common pads, exposed via, test points, and so on.

Stencil Design Checking Rules

Vayo-Stencil Designer also provides 50+ checking rules to ensure the quality of stencil design. Before exporting the final stencil Gerber file, the software will check every aperture in details per the checking rules, so as to detect and address the omissions or defects as early as possible. Besides these 50+ checking rules, Vayo Technology also provides rule customization service.

This stencil design automation software not only focuses on the frontline engineers’ demands, but also pays attention to the retention of know-how.
