Stencil printing is core process in the Surface Mount Technology (SMT) manufacturing process and plays a crucial role in SMT production. However, in the current forms of Stencil printing design, past experiences know-how are difficult to pass down, standards and requirements cannot be digitalized, and stencil know-how cannot reuse. This situation not only hampers quality stability but also prevents the digitalization of valuable know-how, impacting a factory's ability to swiftly respond to new product introductions (NPI) and deliveries. Most importantly, we have corporate know-how library allow you to centralize know-how for competition advantage.
Rapid Intelligent Design
Know-how Digitalization Database
Ensure Quality Stability
Quickly Respond to NPI ProductionStencil is the core process of the entire PCBA, as we have found that 70% of issues originate from the stencil. This is because every aperture on each stencil represents a potential risk. Therefore, if we can address stencil-related issues effectively, we can define the overall quality of the entire PCBA.
Vayo's Stencil solution can digitalize factory’s past know-how and engineers' experience into your digitalized know-how database, enabling quick reuse in new NPIs. This not only saves time but also benefits engineers at every site, facilitating efficient collaboration and knowledge sharing.
When new product comes into production, SMT process engineers will be able to obtain apertures automatically for those packages available in the library. This automatic know-how reuse approach spare engineers from repetitive operations; most importantly, engineers without such experience or deep knowledge will reach consistent result.
Vayo’s solution only allow senior engineers to manage the centralized knowledge base, all other engineers just apply them for new products . The manufacturing team can review top n defects, and make continuous improvement related to stencil apertures.
For big organizations with worldwide sites/factories, global deployment with centralized management team allows you to manage best practice for worldwide manufacturing sites; it not only minimizes business risks, but also enables business expansion.
Vayo solution converts traditional human inspection of aperture design (from external suppliers) to intelligent/automatic way with powerful checks, which not only increase work efficiency of SMT process engineers, but also guarantee high quality design to stencil apertures.
Vayo’s solution can check the difference with the past aperture design automatically to ensure consistency of core PCBA process, save lots of time and maintain high quality.
Vayo solution records aperture usage for every product, it allows you to trace all applied products if there is a risky aperture, like job name, PN, package, project… you can track aperture usage on every products and query by aperture ID, product, date, engineer.
Stencil Designer comes with flexible aperture pattern creation function, it contains plenty of pattern templates and allow end-users to select & fine-tine them easily; more over it support DXF graphic import/export for special aperture design.
Stencil Designer comes with automatic processing & optimization approaches for special pads (thermal, common shared, test points …), safe distance to via holes, step generation & etc.
Pin-in-paste is a common concern in stencil production, and Vayo solution offers a specialized set of formulas to help you calculate the filling rate and determine the required solder paste volume. This enables you to identify the best solution for your specific needs efficiently.
In contrast to the manual preparation of stencils and the management of processes and teams, Vayo's stencil designer presents numerous clear benefits.
For OEM companies (outsourcing PCBA to external EMS), you could extract process experience for products built in the past (critical package, key process), achieve
process traceability for existing EMS suppliers; then automatic recommend such best practice for new products (NPI), and quickly verify the process consistency.
