Introduction to types of PCB tunnel ovens, applicable baking processes and manufacturer recommendations for tunnel ovens

Affected by the diversified baking and curing needs of PCB circuit boards, there are many types of PCB circuit boards, and each tunnel furnace manufacturer has different names for its products. This time we are honored to interview the energy-saving experts in the PCB circuit board industry. The representative brand, the technical engineer of Jiangxi Intelligent Technology Co., Ltd., will provide you with an in-depth analysis and sharing of the types of tunnel ovens dedicated to PCB circuit boards, as well as the types of tunnel oven oven drying lines suitable for each process and manufacturer recommendations.

1. Introduction to tunnel furnaces in PCB industry:

Under the pressure of carbon neutrality and increasingly severe environmental pollution, PCB manufacturers have an urgent need to accelerate the application of clean energy, save industrial electricity, and improve product, brand, cost and other market competitive advantages. At the same time, they are affected by the energy supply of regional parks. As well as the impact of the safety of large-scale baking and heating processes, drying equipment such as tunnel ovens in the PCB industry are basically electric-heated tunnel ovens, and focus on PCB circuits such as fire safety, energy saving, stability, and high production speed benefits. The core key factors of plate tunnel furnace are the technical strength, industry reputation, application experience, quality level and service experience of tunnel furnace manufacturers.

Secondly, unlike tunnel ovens in other industries, which mainly use mesh belts, there are many ways to feed PCB circuit boards into tunnel ovens. Mainly because of economic benefits, PCBs often need to be baked on both sides at the same time, while mesh belt tunnel ovens Direct contact with the PCB board surface may cause the PCB panel ink to be stuck to the mesh tape, affecting the quality of the PCB circuit board.

2. Introduction to PCB tunnel furnace types and applicable baking processes and recommendations from circuit board tunnel furnace oven manufacturers

(Introducing the products of Jiangxi Xinjinhui Intelligent Technology Co., Ltd. as a representative brand manufacturer of energy-saving tunnel furnaces)

1. Flip-type tunnel oven oven drying production line

The page turning conveying system developed based on the patented fiberglass rod can simultaneously meet the baking and curing needs of double-sided multi-layer circuit boards after solder mask development and text printing. At the same time, based on the characteristics of fiberglass rod materials such as non-heat absorption, heat loss can be greatly reduced. Combined with the unique design of Xinjinhui turning tunnel furnace, the energy saving is far better than the industry, mature and stable.

2. Suspended tunnel oven oven drying production line

It adopts a self-developed suspension conveying system, which is suitable for drying after printing, hole plugging or spraying of multi-layer circuit boards. The latest third generation of suspended text post-baking tunnel oven drying line has a board spacing exceeding 15mm. Compared with the first generation Energy saving increased by 55%, and it was released at the International Electronic Circuit (Shenzhen) Exhibition in December 2023, causing a sensation in the global PCB industry. A large number of practitioners paid attention and discussed it, and many listed PCB companies visited and consulted.

3. Side clamp tunnel oven oven drying production line

PCB double-sided solder mask side-clamp pre-baking line is mainly used for drying double-sided multi-layer circuit boards after printing or spraying. It has a variety of board spacing versions to choose from to meet customer site and process requirements.

4. Side-armed tunnel oven oven drying production line

PCB double-sided side-hugging pre-baking tunnel oven drying production line is mainly used for drying double-sided multi-layer circuit boards after printing or spraying, and is suitable for PCB sheets with a thickness of 0.8mm or above.

5. Mesh belt tunnel oven oven drying production line

The mesh belt tunnel furnace is the most common tunnel furnace product. Its structure is relatively simple. Because it is not suitable for double-sided drying, it is mainly used in the PCB industry for cutting materials and removing stress.

In addition to the above five common ones, there are also roller-type IR far-infrared tunnel ovens, double-sided solder mask U-shaped IR far-infrared tunnel ovens, rack-type hot air tunnel oven oven drying production lines, etc.

3. PCB circuit board tunnel furnace customization and PCB circuit board special tunnel furnace manufacturer recommendations

PCB tunnel furnace ovens have strict requirements on energy saving, safety, stability, etc. Secondly, due to the differences in PCB products produced by various PCB manufacturers, all the tunnel furnace process requirements are also different, so tunnel furnace customization is often required. There are not many manufacturers with completely independent R&D, design and production customization capabilities in the field of PCB tunnel furnace oven drying production line equipment in China. Such tunnel furnace manufacturers have high requirements for industry experience, technology accumulation and manufacturing process. It is recommended to choose companies like Jiangxi Tunnel furnace manufacturers such as Xinjinhui Intelligent Technology Co., Ltd. and Dongguan Pengli Energy Saving Equipment Co., Ltd. are recognized and widely used by PCB factories.
