In comparison to other solder paste inspection systems, the SPI-Line 3D provides a true accurate three-dimensional measurement of applied solder paste. The solder paste printing is inspected for form, height, surface area, bridges, volume, x/y offset and coplanarity.
The SPI system provides:
- camera head optimised for speed
- 180 images per second at 4 megapixel resolution
- highly precise 3D image capturing based
- on fringe projection technology
- operating without moving parts
- double-sided projection for 100% shadow-free measurement
- intuitive software SPI-Pilot
- touchscreen interface
The easy-to-use software guarantees a generation of test programs in less than 10 minutes.
Utilizing the SPI-Line 3D opens new opportunities for your processes:
- Close-loop to paste printer
- Connection to AOI/AXI repair station
Inspection Program Generation
Debugging and Analysis
Precise three-dimensional solder paste printing measurement
The SPI-PILOT software features optimised inspection functions to evaluate the following criteria:
- Surface area
- X/Y offset
PCB warpage is compensated for by up to +/- 5 mm by hardware and software guaranteeing precise measurement of deflected and bulged boards.
Most innovative 3D image capturing technology “Made in Germany”
A camera head specially developed in Germany provides highly precise 3D image captures of the solder paste printing. The camera head is functionally based on the fringe projection principle, operating without moving parts.
Camera and projector are synchronized at 180 images per second. This extremely high image capturing speed is the basis for one of the fastest 3D solder paste inspection systems on the market.
The camera head is offered in three different configurations determined by lateral resolutions of 10 µm, 15 µm and 20 µm.
Utilizing fringe projection technology, the system reacts very flexibly to different topographies. Hence, 3D measurement is reproducible and guarantees excellent precision.
SPI-PILOT – new standards in operator convenience
The touchscreen operated system guarantees minimal effort in test program generation by virtue of intuitive software features. With the help of the SPI-Wizard you can generate an inspection program in less than 10 minutes!
A powerful import module for Gerber data and CAD formats is available for automatic generation of test programs.
You store, evaluate and process all captured images in a 3D visualization. A module for statistical process control (SPC module) is available as an add-on option.
