SMT stencil design is an essential step of SMT procedure and determines the soldering quality of PCBA. Along its importance, stencil design also faces various challenges, such as heavy workload for engineers of stencil requirements preparation, repeated communication with outsourcing manufacturers and outsourced stencil validation, or difficulty of process know-how retaining.

For enterprises, every product carries the experience of engineers. In the past, these experience could only be retained in the brain as personal experience, which can hardly be passed down once these experienced engineers resigned. While things become different nowadays, more and more intelligent tools could be used to change the situation.

Vayo-Stencil Designer is an intelligent software for stencil design developed by Vayo Technology and features digitalization of process know-how.

In this article, we will have an understanding on how could the software achieve the process know-how digitalization by aperture learning function. The aperture learning process mainly includes following five steps.

1. To import the CAD data of PCB design.

2. To import Gerber data.

3. To align the layer of Gerber and CAD data.

4. To conduct aperture learning process.

5. To manage the learned aperture.

Following the step-by-step guide, the learning process is quite simple and fast. By learning stencil aperture into the central aperture library, the enterprise could establish their own special aperture library.

With the aperture library, the process engineers could design the stencil by themselves instead of preparing stencil requirements for outsourcing, which could not only save time, but also save the effort to communicate with the stencil manufactures.

Besides the aperture learning function, the Stencil Designer also comes with comprehensive stencil check rules to automatic verify the quality of designed stencil and built-in configurable aperture patterns to support automatic stencil design.
