Heller
1700EXL
The Heller 1700EXL is a forced convection reflow oven in the EXL series. The Heller 1700EXL has six heating zones and one internal cooling zone. The Heller 1700EXL has line speeds up to 32 inches (80 cm) per minute.[1][2]
What it is
General reference — not yet source-verifiedA reflow oven heats assemblies in a controlled thermal profile so solder paste reflows and then solidifies into electrical and mechanical joints. Forced convection reflow ovens circulate heated process gas through multiple thermal sections to balance heat transfer, throughput, and profile control across an assembly.
How it works
General reference — not yet source-verifiedA reflow oven transports assemblies through preheat, soak, peak heating, and cooling regions while convection transfers heat into the board and mounted parts. Process recipes in this class of equipment typically control zone temperatures, conveyor motion, atmosphere selection, and profile verification so the assembly sees the intended thermal history.
Where it fits in the process flow
General reference — not yet source-verifiedReflow ovens are used after solder paste deposition and component placement in electronics assembly. Reflow ovens are followed by inspection and any downstream cleaning or test operations required by the product flow.
Applications
General reference — not yet source-verifiedForced convection reflow ovens are used where solder joints must be formed across populated assemblies with controlled heating and cooling. The equipment class supports process development and production for assemblies that combine varied package masses, substrate types, and thermal sensitivities.
