Solder paste printing quality is becoming more important, because electronic products is becoming preciser, and components is becoming smaller.  Solder Paste Inspection (SPI) is a key inspection equipment to control the solder paste printing quality in SMT.

SPI can inspect the solder paste, such as volume, area, height, XY offset, shape, bridge, etc. on PCB. The principle of optics and the triangulation calculation the core technologies in solder paste inspection. Nowadays, SPI has the powerful SPC process control software. SPC can effectively ensure good solder paste printing quality, greatly reduce the possibility of defective rate of finished products.

There are many manufacturers provide solder paste inspection (SPI). But, there are few article list them.  Thus, we introduces top 10 SPI manufacturers around the world. In a word, they are are Omron, CyberOptics, Viscom, VCTA, Vi TECHNOLOGY, Orbotech, Kohyoung, TRI, Saki, and SEHO Systems GmbH.
