The Pearl River Delta is home to many excellent domestic magnetic component manufacturers. Many cutting-edge and popular transformer application technologies were first developed and are gradually being mass-produced here...
In recent years, the market demand for planar transformers has been growing exponentially, and the supply situation of Dongguan Junjia Electronics Technology Co., Ltd. (hereinafter referred to as "Junjia Electronics") is no exception. Junjia Electronics has assessed the future growth potential of planar transformers and, combined with its existing advantages, is shifting its development focus towards this product.
planar transformer
Founded in 2010, Junjia Electronics began exploring and developing planar electronic transformers in 2016, and established a planar transformer division in the same year. By 2017, they had achieved mass production capacity for planar transformers, and currently have a full production capacity of 100,000 units per week.
The superiority of the new and old transformer solutions is immediately apparent.
Today, Junjia Electronics has accumulated a wealth of valuable experience in the research and development and production of planar transformers. Previously, when serving a manufacturer of 1800W server power supplies, Junjia Electronics encountered a situation where the transformers used employed traditional manufacturing processes, resulting in low production capacity, high costs, and large size. After optimizing the design to a planar transformer, Junjia Electronics increased the product's output efficiency from 92% to 93.5%, doubled daily production capacity, and resolved the customer's supply issues. The product size was also optimized from 55*60*58mm to 51*55*42mm for a planar transformer, significantly saving space. Overall costs were also reduced by 10%.
In addition to the experience mentioned above, in the actual process of serving customers, downstream manufacturers often raise technical requirements for Junjia Electronics' high-power planar transformers, such as safety regulations, efficiency, temperature rise, and size. Junjia Electronics has overcome and resolved these issues within the feasible scope.
During this period, Junjia Electronics has built a complete supply chain and a comprehensive quality system. Gong Changhong, Deputy General Manager of Junjia Electronics, said that Junjia Electronics can now provide rapid response and high-quality service in terms of product development and design, delivery time, and product quality.
Multiple factors have led to an increase in the demand for planar transformers.
Gong Changhong believes that the main reasons for the significant increase in demand for planar transformers are: 1. Market demand has changed, with end users demanding higher efficiency, larger power, smaller size, and lower temperature performance of transformers; 2. Increasing labor costs have led to higher production costs for traditional transformers; 3. High turnover of human resources in traditional processes has resulted in poorer product consistency, thus increasing market demand for planar transformers.
From servers to automotive, energy storage, and 5G communications...
As downstream end-product solutions gradually adapt to changes, the application scenarios for high-power planar transformers are expanding. Currently, Junjia Electronics has already achieved some success in markets such as server racks, PC gold-rated power supplies, and 5G communications. Gong Changhong told reporters that Junjia Electronics' main focus, server power supply projects, is currently in a deep cooperation phase with demand manufacturers. Customers particularly value Junjia's development, delivery, and quality control capabilities, which are Junjia Electronics' most significant advantages.
Junjia Electronics has also expanded its high-power planar transformer business through multiple channels, and its products are gradually being applied in energy storage inverters, charging pile power supplies, vehicle DC-DC converters, military and other markets.
Expanding scale, pursuing high-power, high-end strategies, and building a platform for co-creation, win-win cooperation, and shared benefits.
To better serve the aforementioned mid-to-high-end markets, they have made significant investments in software, hardware, human resources, and material supply systems. They have also obtained UL CLASS-B insulation system and IATF16949 certifications, as well as national high-tech enterprise certification. They have established a product reliability laboratory and are planning to collaborate with universities to establish an industry-university-research base.
Gong Changhong stated that the market for energy storage power supplies and charging pile power supplies is expected to bring more possibilities for Junjia Electronics' development in the future. To meet such market demand, Junjia Electronics has already established two production plants in Shaoguan and plans to purchase its own factory in a science and technology park in Qingxi, Dongguan this year.
Junjia Electronics is building a learning organization, with regular training sessions for everyone from senior executives to ordinary employees. Gong Changhong believes that talent is a company's most valuable asset; therefore, their focus in recent years has been on team building to attract more outstanding talent.
Regarding the company's future development aspirations, Gong Changhong expressed his hope to attract more customers with a demand for high-power and ultra-high-power transformers, and to cooperate with them so that Junjia Electronics' meticulously developed high-power planar transformers can fully demonstrate their strengths, contribute to safe, healthy, efficient, and energy-saving electricity use, provide customers with innovative products and services, and create a platform for co-creation, win-win, and shared benefits!
