FAQ

1. What is an insert-type tunnel oven used for?

It is mainly used for through-hole (insert-type) electronic components requiring controlled reflow or heat treatment.

2. What is the benefit of vacuum reflow in this system?

Vacuum reduces air voids in solder joints, improving product reliability and consistency.

3. How is product damage prevented during conveying?

The conveyor system uses a smooth mesh or PTFE belt supported by rollers to avoid vibration, scratching, or jamming.

4. Can this oven meet cleanroom requirements?

Yes, it is designed to meet Class 100 cleanliness standards with low particle generation.

5. Is the system customizable?

Yes, dimensions, conveyor type, heating zones, and vacuum configuration can be tailored to specific process requirements.
