Abstract
Reporters obtained the following quote from the background information supplied by the inventors:“Robotic assembly systems assemble computer systems and other devices. One of the expensive elementsin assembly are the modules, such as dual in-line memory modules (DIMMs) inserted into sockets on theboard. A module ins erted incorrectly can damage the module and the socket, which can render the ent ireboard unusable, and is an expensive error considering that there are typical ly 12 to 24 sockets per board,and damaging any one of those sockets can scrap t he entire board. Module insertion needs high accuracywhich accounts for real wo rld variation in pitch, yaw, and rotation of the part on the board. Incorrector incomplete insertion of modules can cause defects and rework for manufacturers. And most insidiously,it may lead to board-level failures long after the board has passed testing at the manufacturer, and hasentered its service life in an e nd-customer product or data center rack.”
