THE SELECTIVE SOLDER MACHINE
The Selective Solder Machine has demonstrated the capability
to give robust solder joints during [SMD] productions of
Printed Circuit Boards that:
  • Have proven 6 sigma capability
  • Meet IPC-A-610C class 2&3 and military 2000A fillet requirements
  • Display a minimum no-clean flux residue
  • Demonstrate a cycle time of 100-110 seconds
  • Provide a process that stays under 363 degrees. [The reflow temperature of 63 Sn x 37 Pb solder]
Model FE3 Omega Controllers
Design - The Selective Solder Machines were designed to:
  • Reflow solder multi-lead components & [SMD] components placed in solder creme, solder bumped with flux
  • Use solder preforms or solder washers [with internal flux] on leaded component and 16, 20, 48 pin connectors. Different pin configuration optional.
  • Utilize Tin (Sn) & Lead (Pb) solders and Tin (Sn) & silver (Ag) & Copper (Cu) NEW [Lead Free] solders.
Operation - The Selective Solder Machines is fed a PC Board Assembly, placed in the machine, automatically indexed, and Processes controlled by:
  • Time controlled pneumatic [Jacob's Ladder] feed mechanism
  • The process requirements
  • Temperature controllers; Preheat station; Solder Station; Cool-down station
