Solder paste misprint cleaning

A processor receives solder paste information, where the solder paste information describes a solder paste used in assembly of a printed circuit board. A processor determines a minimum magnetic force required for removing the solder paste from the printed circuit board based on the solder paste information. A processor receives electromagnet information, where the electromagnet information describes an electromagnet used in cleaning of a misprint of the solder paste on the printed circuit board. A processor determines a minimum amount of power to provide the electromagnet to induce the minimum magnetic force in the electromagnet, where the determination of the amount of power is based on the electromagnet information and the minimum magnetic force. A processor adjusts an amount of power applied to the electromagnet to at least the determined minimum amount of power to clean the misprint of the solder paste from the printed circuit board.

Reflow soldering apparatus, system and method

A reflow soldering apparatus, system, and method. The reflow soldering system may include a housing that is alterable between an open state and a closed state, the open state being used for loading and unloading of substrates and the closed state being used during operation. The system may also include a heating assembly located within the chamber and a cooling assembly that is spaced apart from the heating assembly. A support member may be included to support a substrate within the chamber. A first actuator unit may be operably coupled to either the heating and cooling assemblies jointly, or to the support member. Additionally, the system may include a control unit coupled to the first actuator unit to cause relative movement between the substrate and the heating and cooling assemblies. Thus, the substrate can move between the heating and cooling assemblies during the various stages of the reflow soldering process.
