Compact Reflow Ovens for SMT Assembly Applications

High-volume quality achieved in a space-saving zone configuration

One of the key features of ANTOM’s compact reflow ovens is their ability to achieve mass-production-level quality within a limited installation footprint.
In SMT applications, compact reflow ovens are commonly used for prototyping, evaluation, and reliability testing.
However, ANTOM also offers space-saving reflow ovens with a total length of 4 meters that can support production use.
High-volume quality achieved in a space-saving zone configuration
At first glance, a 4-meter-long system may not seem “compact.”
However, consider this configuration: eight heating zones combined with two cooling zones within a total length of just 4 meters.
For comparable configurations from other manufacturers, a total system length of 5 to 6 meters is typically unavoidable.

This compact design allows manufacturers to support various production styles—even in space-limited environments—without restricting production scale, including:

– Mass production lines
– Pre-production or pilot runs
– High-mix, low-volume manufacturing

Providing only what truly matters for SMT production—without unnecessary excess

In recent years, many manufacturers have begun offering reflow ovens with nitrogen capability as a standard specification.

However, in actual production environments, it is not uncommon to hear concerns such as:

– Sufficient quality is achieved under air atmosphere
– Many processes do not require nitrogen
– Unnecessary specifications lead to higher costs

At ANTOM, we clearly separate designs for air-only operation and nitrogen-capable operation, depending on the application.

For example, a nitrogen atmosphere is required in applications such as:

– Workpiece materials or solder alloys that are sensitive to oxidation
– Assembly of fine-pitch components
– Processes where yield stability is critical

In such cases, ANTOM’s SMT reflow ovens can be operated with a nitrogen atmosphere only when required.
The ability to use nitrogen and designing equipment based on nitrogen as a default assumption are fundamentally different concepts.

This distinction enables an optimal balance between equipment cost and soldering quality.

The option of air-only reflow ovens

ANTOM offers dedicated reflow oven solutions designed to maximize soldering quality in air atmosphere environments.
These air-only reflow ovens feature:

– A rational configuration that eliminates unnecessary nitrogen-related specifications
– Stable mass-production quality while keeping initial investment costs low
– A footprint optimized for domestic mass-production lines

ANTOM believes that choosing not to introduce nitrogen-capable equipment into processes where air atmosphere is sufficient is also a sound and correct approach to equipment selection.

Reflow ovens designed from the perspective of SMT production floors

ANTOM has consistently designed reflow ovens based on the following principles:

– Understanding SMT assembly processes in depth
– Designing with real-world production constraints in mind
– Retaining only the functions that are truly necessary

That is why ANTOM’s reflow ovens are often described as “compact, yet fully capable of mass production.”

ANTOM’s SMT reflow ovens meet all of the following requirements:

– Efficient operation in air-only environments
– The ability to use nitrogen only when necessary
– Achieving mass-production quality within limited installation space

Options are also available for applications where air atmosphere is sufficient

Not all heating processes require a nitrogen atmosphere.
ANTOM offers dedicated reflow ovens optimized specifically for operation in air environments.

By eliminating unnecessary functions, these systems reduce both initial investment and operational burden, while reliably delivering the performance required for SMT assembly and heating processes.
ANTOM proposes air-only reflow ovens equipped with exactly what is needed—nothing more, nothing less.
