In order to prevent the PCB printed circuit board from containing or absorbing water or moisture from the outside during the production process, resulting in board explosion, delamination, curling, virtual soldering and other phenomena and problems, so choose the right one Baking equipment is very important. In this issue, the manufacturer’s editor will inventory and analyze for you the different types of tunnel oven ovens dedicated to PCB printed circuit boards, as well as the characteristics and applicability of different PCB circuit board tunnel oven drying line equipment.
1. Flip-type tunnel furnace:
Flip tunnel oven, also known as flip tunnel oven, is mainly used for drying and curing double-sided multi-layer PCB circuit boards after solder mask development or text printing. It is a tunnel dryer that is widely used in the PCB industry. One of the line equipment, the technology is mature and stable, and it is an energy-saving tunnel oven equipment that is compatible with the baking needs of most PCB circuit boards; the representative brand manufacturer of turning tunnel oven: Shenzhen Energy Saving Technology Co., Ltd.
2. Side clamp/side hug tunnel oven:
The difference between the side-clamp/side-hug type drying tunnel oven and the page-turning type mainly lies in the different conveying mechanisms and methods. In addition to drying and curing after solder mask development or text printing, solder mask pre-baking can also be performed. However, there are certain requirements for the thickness of the board, and compared with the flip tunnel oven, the overall length may be longer and the area is larger. It is mainly a tunnel oven equipment that meets the solder mask drying and curing needs of PCB manufacturers; side clamps Representative manufacturer of tunnel ovens: Dongguan Pengli Energy Saving Equipment Co., Ltd.
3.Suspended tunnel oven:
The suspended tunnel furnace is also called the hanging claw tunnel furnace drying line. It is transported by the hanging claw splint. Compared with other types, the internal structure is further simplified, maintenance is more convenient, heat loss is lower, and temperature uniformity is better. , is an ideal solution for PCB energy-saving drying in the future. It has the advantages of various tunnel ovens, but it has higher requirements for the process technology level and production and manufacturing capabilities of tunnel oven manufacturers; currently, the suspension system developed by Jiangxi Xinjinhui Intelligent Technology Co., Ltd. The distance between the drying lines of the suspended tunnel furnace has exceeded 15mm, and the energy saving is 55% higher than that of Xin Jinhui’s own first generation. However, the common plate distance of the industry’s suspended tunnel furnaces is still above 31.75mm. Therefore, Xin Jinhui’s energy-saving tunnel furnace It basically occupies a leading market position in the field and is a representative brand manufacturer of suspended energy-saving tunnel furnaces.
4. Insert-type tunnel furnace:
The rack-type tunnel oven is also called a frame-type tunnel oven. The carrier can be customized and can basically meet the baking needs of various products. The overall structure is also relatively simple and is suitable for semi-automatic, small batch, and miscellaneous material production conditions. ; Due to its simple structure, any professional tunnel furnace manufacturer can produce it. However, considering safety, energy saving, and stability, it is recommended to look for a company ranked among the top ten tunnel furnace brand manufacturers, among which comprehensive strength, reputation, experience and For cost-effectiveness, we recommend Jiangxi Xinjinhui Intelligent Technology Co., Ltd.
5. Mesh belt tunnel furnace
Mesh belt type, also known as mesh belt IR furnace and far infrared mesh belt tunnel furnace, is a relatively common tunnel oven drying line on the market. It adopts a simple mesh belt conveying method and is widely used in various industries, such as: printing, Painting, textile, clothing, electronics, electrical appliances, ceramics and other industries.
6. Roller tunnel furnace:
Roller type tunnel furnace, also known as roller type IR far infrared tunnel furnace oven, compared with mesh belt type tunnel furnace, mainly solves the problem of wear debris pollution caused by mesh belt transportation, and is suitable for baking and drying needs with higher cleanliness requirements.
7. U-shaped double-sided baking tunnel oven:
U-shaped double-sided baking tunnel oven, compared with other IR far-infrared tunnel ovens, adopts a U-shaped design, mainly to meet the baking and curing needs of double-sided panels. Representative brand manufacturer of IR far infrared tunnel oven oven: Shenzhen Xinjinhui Energy Saving Technology Co., Ltd.
8. Tunnel furnace customized drying line:
Tunnel furnace customization is mainly based on the process, designing the transportation method, heating system, internal structure, high-speed air circulation system, ventilation system, exhaust system, filtration system, safety system, anti-fool system, process technology parameters, specifications and size parameters, etc., and Not all tunnel furnace manufacturers have the ability to customize tunnel furnaces. Therefore, in order to ensure production efficiency and safety, energy saving, stability and other requirements, it is necessary to choose a tunnel furnace manufacturer with full R&D and manufacturing capabilities, rich industry experience, and a certain industry reputation. For example: companies listed in the top ten domestic tunnel furnace manufacturers include Jiangxi Xinjinhui Intelligent Technology Co., Ltd., Dongguan Pengli Energy Saving Equipment Co., Ltd., Shenzhen Xinjinhui Energy Saving Technology Co., Ltd., etc.
