PROJECT GOALS
AND OBJECTIVES

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.

SYSTEM
CONFIGURATION
  • unloading system for carriers with microchips;
  • system of manual placement of carriers with microchips on the belt;
  • belt (conveyor) type microchips transport system;
  • positioning device;
  • laser marker;
  • optical scanning module;
  • machine vision system with feedback for marking quality control;
  • device for pushing microchips into containers;
  • microchip packages protection system;
  • electrostatic discharge protection system;
  • software;
  • unauthorized access protection system;
  • control system (electronics, pneumatics, touch screen);

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.

  • Marking Control Software is software for direct marking process control.
  • Key features of the software:
  • Creation of marking drawings. To create a drawing, you can use the drawing functions of graphic primitives: rectangle, ellipse, polygon, grid, text or serial number, barcode.
  • Import of the external image files.
  • Export of PLT files.
  • Editing of drawings.
  • Tones editing.
  • Inserting of automatically incremented fields.
  • Inserting of automatically updated fields: date, time, serial number.
  • Changing the marking filling parameters.
  • Marking preview.
  • Offline processing of marking files.
  • Laser parameters adjustment.
  • Marking position adjustment.
  • User access rights differentiation.
  • Saving of all parameters into the database.
  • Storing of information on all marked products.
  • Automatic and manual marking operation mode.
