THERMAL SYSTEMSIt’s your choice – air doping or nitrogenPAirdopingIn the case of air doping, the processchamber is contaminated with atmosphericoxygen. A defined leak is createdin the process chamber by meansof a servo-valve to this end, which isopened just far enough to generatethe desired residual oxygen value. Thereflow system’s nitrogen consumptionis not influenced by this procedure, andalways remains constant. Air doping isadvisable for SMD production lines forwhich loading circumstances and conveyorwidths vary only minimally in thereflow oven.StickstoffregelungWith the nitrogen control the desiredppm level is held constant by continuouslymeasuring the residual oxygenvalue. This is accomplished by injectingnitrogen into the process chamberin a variable fashion dependingupon the measured residual oxygenvalue. This results in varying nitrogenconsumption levels depending uponthe extent to which the reflow systemis loaded with PCBs and the selectedconveyor width, allowing for reducednitrogen consumption.peakzone coolingzoneEasy maintenanceThe great advantage of the pyrolysisis the maintenance free technology.The high granulate life time makes aperiod of a year for the change of thegranulate possible.With the new condensate trap Rehmbreaks new ground.
