3D-SPI Board

3D reference plate for evaluating the measurement capability of SPI systems

3D-SPI Board – Reference standard for validating Solder Paste Inspection systems

Precise solder paste printing is the foundation for efficient and cost-effective SMT production. The 3D-SPI Board, which utilizes a structured glass substrate, reliably ensures the measurability of x, y position, height, volume, and area. This is ideal for direct process control and quality assurance, as it allows for the identification of error sources and the sustainable improvement of manufacturing quality.

The most important advantages in a quick check

Quickly find errors, optimize processes, master audits

Realistic SMT Structures

3D-etched glass substrate replicates typical PCB structures, including defects – simulating realistic paste printing.

Robust Handling

Embedded in an aluminum carrier, durable and easy to handle in any SPI system.

Golden Board for SPIs

A Golden Board enables the comparison of all SPI machines in production, regardless of manufacturer. This supports the standardization of quality levels across all machines.

Reliable SPI Validation

Enables measurements in four different orientations. Since the board is square, it can be fed to the SPI in an orientation of 0, 90, 180, or 270 degrees. This allows for the evaluation of how the SPI machine performs when evaluating a panel board.

High Precision

Stable and high accuracy is ensured through exposure using a mask – as in the semiconductor industry – and the subsequent etching process. This represents the state of the art.

Diverse Pad Structures

Includes 0201–0603, QFP to BGA (0.5 mm pitch), ground planes, and simulated defects (bridges, incomplete, and missing pads).

Measurement Accuracy of SPI

Interpret SPI results more effectively by understanding the measurement accuracy

Analysis of the measured height in relation to the deposit size

The measurement indicates that the height measured by the SPI depends on the size of the deposit. Deposits of smaller components tend to be measured as ‘flatter’. This is an interesting effect, considering that all structures on the 3D SPI Board have the same height.

Influence of the 3D Board’s orientation on the displayed volume

For the test, the 3D SPI Board was measured in two different orientations. A 10% difference in the displayed volume becomes apparent. This is critical if the circuits on the panel have different orientations.
