Beamworks Spark400 SMT Selective Laser Soldering System

       
The Spark 400 is a multi-process assembly platform designed for assembling low to medium volume PCB lots, automatic rework and prototype assembly. It concurrently performs paste dispensing, component placement and laser soldering (using 4 lasers that work simultaneously and independently), without impacting already assembled components.

Main Benefits

  • Closed loop temperature controlled soldering
  • No stencil required Spark 400 fully automates rework by selectively dispensing solder paste, placing components and processing reflow without heating neighboring components.
  • Flexible operation allows for fast turn around Spark 400 makes production planning easier, e.g. the production plan does not have to be reshuffled for the SMT line if some components do not make it on time because assembly can proceed with one or more missing components.
  • Precise heating without impacting adjacent components
  • Small footprint
  • No baking of moisture sensitive components
  • If a certain lead of a given component is connected to power or ground plane, the laser soldering time is longer for that lead than for the adjacent lead not connected to a heat sink.

System Features

  • Vision system for auto alignment using board fiducials
  • Using standard CAD and BOM files and utilizing on-board component library of components geometry
  • Win 2000 operation system and comfortable GUI
  • Simultaneous operation of 4 lasers provides high soldering throughput
  • Full SMEMA support allows in-line operation
  • Either stand alone or in-line operation
