Vacuum the chamber and remove the flux residue and soldering balls Reflow Oven full convection, excellent soldering performance.Clean the ventilation pipe with a cleaning agent.Once the chamber temperature decreases to room temperature, open the hood and clean the inside surface of chamber with a proper cleaning agent.Clean the photoelectric switches which detect whether a board is within or outstide of the reflow oven.Check conveyor chains, sprockets, mesh and the automatic lubrication system.Clean and wipe down the machine daily.The following is a list of daily, house-keeping tasks to be accomplished for maintaining a reflow oven: The Benchtop Reflow oven uses highly efficient infrared heating elements, and has several thermocouple temperature gauges. More info Low to Medium Volume 1800HT Conveyor Reflow Oven Conveyor reflow solder oven with 50' (1270mm) long heating tunnel for low to medium volume surface mount assembly. Furukawa Electric, a leading manufacturer of reflow soldering systems, has now developed an oven designed for the Sn-Ag process, which at present seems to show. This will cause inaccurate thermal data readings and the thermal controller will make the wrong adjustment instructions. GF-125 Five Zone Benchtop Reflow Oven Five (5) zone horizontal convection PCB reflow oven with 56' (1423mm) long heating tunnel for medium-volume or high-mix assembly. This setpoint is in correspondence with the temperature the circuit board should be exposed to while passing through the zone. Each zone has a specific thermal set point. According to length, there may be five, eight, or twelve zones or even more. ![]() Although there is a flux collection system in modern reflow machines, there still is a big probability tha flux will adhere to the inert air ventilation pipe and thermal regulator panel. Reflow ovens have a number of heating zones followed by cooling sections. One of the most important tasks for properly maintaining a reflow oven is remove the built-up flux residue inside the oven's chamber. Proper reflow overn maintenance can extend its life cycle, keep the machine in good condition, and improve production efficiency and product quality. ![]()
