Features and Upgrades
Automatic Stencil Cleaning System
As standard the HP Series of Screen Printers from SJ Innotech come with an Automatic Stencil Cleaning System which uses a two step vacuum cleaning unit with the option of three cleaning methods, IPA, Vacuum and Blower while also allowing for manual cleaning as well if required. After the stencil has been cleaned the system automatically returns to stand by mode ready for the next cleaning interval.
Upgraded 3D Inspection
The SPI machines in the SJ Innotech HP series come with an upgraded 3D Inspection System as standard. The can even further reduce the number final defective products by allowing for a more accurate inspection of excessive solder and shape defects while adding the ability to check for bridges. The system provides real-time feedback and control of the screen printing system through the 3D Inspection system to provide users to develop the best quality products possible.
SPI Offset Control
Taking advantage of the 3D Inspection System the SPI Machines are capable of performing accurate size, height, volume and location inspections of all solder paste deposits. This uses an SPI Offset Communication Control by taking images from each axis to combine these into a single image to determine the offset of each deposit to ensure that it is in the correct location. This increases the productivity and minimises the need for rework on defective boards.
