Recently, Opto-Intel Technologies Co., Ltd. independent research and development of the core features of the product Vacuum Solder Reflow Oven VSR-20MPA was identified as the second batch of Chongqing City, the first (sets) of major technology and equipment products.

Chongqing Municipal Economic and Information Commission, the relevant person in charge of the explanation, the first (sets) of major technical equipment refers to the independent innovation and research and development, in terms of varieties, specifications and technical parameters and other aspects of a major breakthrough, with intellectual property rights but in the early stages of market promotion of complete sets of equipment, single equipment and key core components and other equipment products, these products have a high and new technology breakthroughs, drive industrial development, market potential and other characteristics.

Vacuum reflow soldering technology is an advanced process technology related to chip packaging, it is through the traditional reflow soldering process to increase the vacuum exhaust phase, remove the liquid solder in the air holes, can achieve the chip and circuit substrate cavity-free brazing (can obtain very low void rate such as <1% of the solder layer). The technology and equipment have been widely used in the field of high-reliability high-power chip packaging, such as 5G communications, new energy vehicles, smart grid, rail transit, laser processing, aerospace military and other fields.

The Vacuum Solder Reflow Oven VSR-20MPA from Opto-intel is mainly used to realise high-quality void-free chip eutectic reflow soldering process. It uses vacuum, reducing atmosphere and unique plasma technology to optimise soldering quality, and is the first in the industry to adopt the advanced technology of microwave plasma-assisted de-oxidation, which perfectly empowers the reflow process, and is especially suitable for applications in semiconductor lasers, optical communication modules, microwave T/R components, and power chip packaging.

VSR-20MPA is a high-performance equipment. Its main features include the ability to achieve vacuum reflow soldering without voids, non-destructive microwave plasma-assisted technology for surface treatment of workpieces and perfect compatibility with low-temperature solder processes. It also has the ability to control the temperature profile quickly and accurately. In addition, it is equipped with a powerful self-developed Windows+PLC graphical control interface, which makes it easy to achieve repeatable, highly flexible and data-traceable production processes.

Government of Chongqing Municipality has studied the successive introduction of “Chongqing Municipality to accelerate the development of integrated circuit industry a number of policies""and “the Chongqing Municipality of manufacturing high-quality development 14th Five-Year Plan (2021-2025)” as well as “Chongqing Municipality of a new generation of electronic information manufacturing industry clusters high-quality development action plan ( 2023-2027)” and a series of policies and measures to promote the formation of "complementary advantages, mismatch synergies, both hard and soft" development pattern.

Opto-Intel Technologies Co., Ltd. is located in Western Science City (Beibei) Section of Chongqing together with Chongqing Sensor Industrial Base.
