Microchip laser marking machine Theseus SCI LMS-1500
Start of project: 08.2017, end of project: 01.2018.
JSC “INTEGRAL” “TRANSISTOR” Branch, Republic of Belarus
The microchip laser marking machine Theseus SCI LMS-1500 is designed for marking microchips in ceramic-and-metal packages like CDFP, CQFP, loaded into the carriers, as well as without them, both in automatic and manual feeding to the path.
All records concerning the operation of the laser marking machine including the number of marked microchips, marking file information, batch number, part type, name of the operator who produced the marking, marking date and time are stored in database. The database is generated automatically. Recording of values after each marking provides real-time information update. The information is stored with accumulation for at least 10 years.
The machine is equipped with Siemens programmable controller, specialized marking software, conveyor belt mechanism, controlled air cylinder, YASKAWA servo drive, Siemens touch screen, automatic handling system and a conveyor belt with a flat transport element for moving the microchip to the marking station.

SOFTWARE ‘ icon_select=’no’ icon=’ue800′ font=’entypo-fontello’]
The software consists of two modules, visual inspection module Visionkit and module for marking process control and creating marking templates Marking Control Software.
Visionkit is specialized software for positioning using machine vision. After optical positioning using the specialized optical system, the position deviation data is transferred to the marking software system for compensation and correction, which allows obtaining accurate marking position on the marked microchip.
