Reflow Soldering Machine Controller

A leading manufacturer of soldering equipment needed a circuit to control its new automated reflow soldering machine. Voler was selected to design the circuit board, firmware, and PC software. The circuit has both analog and digital circuit design with signal conditioning for thermocouples, RTDs, flow sensors, and control actuators.

We wrote firmware for the on-board microcontroller to provide closed loop PID control and communication to a PC. We wrote an extensive application in Windows to set up and operate the machine. We worked closely with the customer’s mechanical engineers to develop new hardware and software technology to perform the desired functions with high quality to minimize problems in volume production.
