Product Information:

The Precision Electronic Product Chain Plate Tunnel Furnace is a high-efficiency, continuous industrial heat treatment system. It uses stainless steel chain plates as the conveying carrier and relies on a high-precision temperature control system combined with an optimized hot air circulation structure, allowing electronic products to continuously pass through the heating zones according to the preset temperature profile. This equipment is specially designed for drying, curing, aging, and sintering processes of electronic components, semiconductor discrete devices, automotive electronics, and other precision products. It features excellent temperature uniformity and high-level automated production capability.

Product Applications

FAQ

Q1: How does the equipment prevent precision electronic products from being damaged by excessive temperature?

A1: The equipment adopts high-precision PID microcomputer temperature control and multi-zone independent temperature control design, combined with an over-temperature power-off protection system. If any heating zone exceeds the preset safety temperature, the system will automatically cut off the heating power and activate an audible and visual alarm.

Q2: Will the chain plate material contaminate or scratch electronic products?

A2: No. The conveyor system uses high-quality industrial-grade SUS304 stainless steel chain plates with finely polished surfaces, providing a smooth and flat conveying surface. For highly sensitive products, customized solutions such as non-metallic conveyor plates (e.g., PTFE) or special chain plates with fixtures are also available.

Q3: How is temperature uniformity inside the furnace ensured?

A3: The furnace is equipped with high-performance, high-volume circulation fans. Through specially designed air guide channels on both sides or the top, hot air circulates strongly inside the furnace, evenly surrounding the products and controlling local temperature differences within ±2.5℃.

Q4: Can the conveyor speed and temperature be adjusted according to different product processes?

A4: Yes. The equipment is equipped with a variable frequency speed control system and an intelligent touch screen. Operators can digitally adjust the conveyor speed and independently set the temperature curve of each heating section according to process requirements.

Q5: What is the difference between a chain plate tunnel furnace and a conventional mesh belt tunnel furnace?

A5: Mesh belt tunnel furnaces are suitable for lightweight and regularly shaped products. Chain plate tunnel furnaces provide stronger load-bearing capacity and more stable operation, eliminating common issues such as mesh belt deviation, loosening, and vibration. They are more suitable for transporting precision electronic components with carriers or fixtures.
