Tunnel-type reflow ovens move PCB assemblies through a sequence of controlled heating and cooling sections. Continuous conveyor transport makes this format suitable for SMT production in which boards follow a repeatable soldering profile after component placement.
The number and configuration of zones influence how closely the oven can shape the thermal cycle. Conveyor speed, air circulation and loading all affect the temperatures reached by the assembly. Lead-free soldering and boards with uneven thermal mass require particular attention to component limits and temperature distribution.
Equipment selection should consider working width, conveyor support and the required production rate at the validated recipe. Atmosphere options and cooling capacity may also influence the result. Periodic profiling, cleaning and checks on the transport system help maintain consistency as board designs and production loads change.
