Semi-Automated SMT Pickup and Place Machine


The CAT90-SA pick and place systems are semi-automatic machines featuring software guidance and the latest high resolution vision technology. Systems are designed for placement of various SMT components such as capacitors, resistors, SOIC’s, fine-pitch QFP’s, and many other SMD’s. Software control ensures error free pick and place sequences on the assembly. This is a critical feature that greatly reduces debugging of prototype assemblies. High productivity is achieved by eliminating the need to refer to a PCB layout / schematic diagram as with manual machines.

Software guides the operator to pick up an appropriate component from a specific bin (handles loose parts) or feeders and then displays the corresponding placement location on a virtual PCB. The operator simply moves the placement arm along X and Y axis’ while as necessary, referring to the camera monitor for a magnified view. To place fine pitch components, the camera may be rotated to view all 4 sides of a component. With the placement arm automatically locked in place, X and Y micrometers of a positioning stage, along with Theta rotation are used to provide necessary fine adjustments for component positioning. The software also allows an unlimited number of feeders and carousels that may be programmed for each assembly. Both feeders and the carousel are interchangeable in mid assembly within a matter of seconds.

In comparison to manual pick and place systems, CAT90-SA delivers higher productivity (up to 1,000 CPH), eliminates placement errors, and greatly reduces operator fatigue. On the flip side, fully automatic pick and place systems require expensive feeders, are time consuming to program, and are unable to place loose parts. The overall cost of owning and operating an automatic system is typically not efficient for prototype and low volume assembly requirements. This makes the CAT90-SA a very attractive and cost effective solution for prototype and small volume assembly requiring, precise error proof placements
