Top-Side Preheater helps improve selective soldering.
Press Release Summary:
Used as primary preheating function or in combination with ACE discrete preheaters to maintain board temperature during soldering operation, real-time preheating module applies heat to top side of PCB. For high-mass assemblies, unit promotes draw of solder through barrel to top side of board, enhancing formation of solder fillets. Optical pyrometer reads actual PCB temperature with real-time closed loop control.

New Top-Side Preheater from ACE Improves Selective Soldering of High Thermal Mass Assemblies
July 3, 2007 - Spokane Valley, WA - Large, high-mass assemblies are a challenge for any soldering process, but are particularly troublesome for selective soldering, where process heat is applied only to the bottom side of the assembly. The ability to apply continuous, real-time top-side pre-heating during the selective soldering process is critical to achieving good soldering results when processing such assemblies.
ACE Production Technologies announces the introduction of a real-time top side pre-heating module that applies heat to the top side of the PCB during soldering. For high-mass assemblies, this top-side preheating promotes the draw of the solder through the barrel to the top side of the board, enhancing the formation of solder fillets on the top side. The implementation of internal continuous pre-heat, during the selective soldering process, improves thermal distribution and solderability of difficult assemblies.
This function is not practical or possible on machines that grip and robotically move the PCB, since the pre-heater would need to travel with the board and the gripper simply is in the way. The unique design of all ACE KISS Selective Soldering machines keeps the PCB stationary while the flux and solder stations move beneath.
The top-side heating module can be used as the primary pre-heating function, or to maximize productivity when used in combination with ACE discrete pre-heaters to maintain board temperature during the soldering operation. An optical pyrometer reads the actual PCB temperature with real-time closed loop control.
