Ramping up a new model involves a time-consuming process of determining the right printing conditions to use, which largely depends on individual operator skills. Furthermore, the fact that the result cannot be known until actual printing makes it even more difficult.

Even after trial production with the right printing conditions is successfully performed and it comes time to go into full production, the printing conditions may need to be fine-tuned if the first pass yield at the SPI is poor and the quality is not stable, resulting in additional time spent.

Fuji has a solution to this challenge with its printing support system, making it more efficient to set printing conditions, which currently depends on operator skills.

With the printing support system, recommend parameters based on the accumulated data and quality data calculated from the first pass yield are presented, simply by entering printing conditions.

In addition, inspection results are automatically accumulated through SPI linkage. The more that gets registered to the system, the more it will evolve into a database that matches your needs, and more practical printing conditions can be provided.

Through this, printing conditions (parameters) can be determined while comparing quality data and cycle times, without relying on the operator's intuition. When performed under conditions at Fuji, this system reduced the startup time by 57%.

1. Enter the parameters.
2. Optimal conditions are searched for based on past results, and parameters linked to the first pass yield are displayed.
3. Compare the displayed results with the desired production conditions and determine the printing conditions.

Enter the parameters such as the metal stencil thickness or solder particle diameter.

＜Parameters that can be entered＞
Panel (size, panel thickness), solder (manufacturer, model, particle type), mask (size, thickness), squeegee (type: urethane/metal), cleaning mode (dry/vacuum/wet), angle

The system extracts data close to the parameters and desired print quality from the past results database and displays the top ten conditions with the highest scores calculated from the SPI machine's first pass yield and control parameters such as the printing speed and pressure.

Determine the printing parameters, referencing the displayed results. Printing quality can be checked without actual printing, making printing condition setting more efficient.

With the printing support system, which enables ramp-up of new models without relying on the operators' skills and intuition, Fuji is committed to helping you reduce preparation time in the printing process.

NXTR PM also features a variety of production-enhancing functions including automated changeover processes and non-stop exchange of solder cups and cleaning paper.
