The SM421 can be applied to parts from 0603 microchip to 22mm IC part through On-The-Fly recognition technology, which is Samsung's proprietary technology that realizes the placement at the highest speed among medium speed chip mounters. It also allows recognition of parts with fine pitch such as 55mm with 0.4mm pitch by adopting a mega pixel vision system for the Stage camera. It allows IC parts to be placed with high accuracy of 30 microns. It also easily registers parts of complicated shape by supporting the polygon recognition algorithm.
