In recent years, the application of transformer products in markets such as energy storage, automotive electronics, military, and 5G base stations has shown a trend towards high power and flatness. In response to these trends, some transformer manufacturers have made adaptive adjustments and shifted their product development focus to planar transformers.

The Pearl River Delta gathers numerous excellent domestic magnetic component manufacturers, and many cutting-edge and popular transformer application technologies are taking the lead here, with mass production gradually emerging

In recent years, the market demand for flat transformers has doubled, and the supply situation of Dongguan Junjia Electronic Technology Co., Ltd. (hereinafter referred to as "Junjia Electronics") is also the same. Junjia Electronics is assessing the future growth potential of planar transformers and, based on the company's existing advantages, will tilt the development balance towards this product.

Junjia Electronic Flat Transformer

Junjia Electronics was founded in 2010. In 2016, they began to develop flat electronic transformers and established a flat transformer department in the same year. Since 2017, we have been able to meet the large-scale production capacity of flat transformers, and currently our full production capacity has reached 100000 units per week.

Comparison of old and new transformer schemes, with a clear distinction between high and low standards

Up to now, Junjia Electronics has accumulated a wealth of valuable experience in the research and development, production, and other aspects of planar transformers. Previously, when Junjia Electronics was serving a manufacturer producing 1800W server power supplies, the transformer originally used by the manufacturer was a traditional process product with low production capacity, high cost, and large volume. After optimizing its design as a flat transformer, Junjia Electronics increased the product output efficiency from 92% to 93.5%, doubling its daily production capacity and solving the customer's supply problem; The product volume has been optimized from the original 55 * 60 * 58mm to 51 * 55 * 42mm after the flat transformer, greatly saving space; The overall cost has also been relatively reduced by 10% on the original basis.

In addition to the above experience, in the actual process of serving customers, downstream manufacturers often mention technical requirements such as safety regulations, efficiency, temperature rise, size, etc. for the high-power planar transformer of Junjia Electronics. Junjia Electronics has overcome and solved them one by one within feasible limits.

During this period, Junjia Electronics has established a comprehensive supply chain and a complete quality system. Gong Changhong, Deputy General Manager of Junjia Electronics, said that currently Junjia Electronics can achieve rapid response and high-quality service in product development and design, delivery time, product quality, and other aspects.

The demand for multi factor variable planar transformers is increasing

Gong Changhong believes that the main reasons for the significant increase in demand for flat transformers are: 1. There have been new changes in market demand, and end-users have increasingly high requirements for products, gradually pursuing transformer products with high efficiency, high power, small size, low temperature rise, etc; 2. The continuous increase in labor costs has led to higher production costs for traditional transformers; 3. Traditional craftsmanship has a high turnover of human resources, resulting in increasingly poor product consistency. Therefore, the market demand for flat transformers is gradually increasing.

From servers to vehicles, energy storage, 5G communication

With the gradual adjustment of traditional solutions for downstream terminal products, the application scenarios of high-power planar transformers are constantly expanding. At present, Junjia Electronics has made some gains in markets such as server cabinets, PC computer power supplies, and 5G communication. Gong Changhong told reporters that the server power supply project that Junjia Electronics is currently focusing on is in a deep cooperation stage with demand vendors. Customers particularly value Junjia's development, delivery, and quality control capabilities, which are also the most significant advantages of Junjia Electronics.

Junjia Electronics is also expanding its high-power planar transformer business through multiple channels, and its products are gradually being applied in the energy storage inverter power supply, charging pile power supply market, vehicle DC-DC, military and other markets.

Expand scale, take the high-power high-end route, and create a co creation, win-win and sharing platform

To serve the above-mentioned mid to high end markets, they have made extensive layouts in software, hardware, manpower, and material supply systems. They have also obtained UL CLASS-B insulation system and IATF16949 certification, national high-tech enterprise certification, established product reliability laboratories, and are planning to cooperate with universities to establish industry university research bases.

Gong Changhong stated that it is expected that the energy storage power supply, charging pile power supply and other markets will bring more possibilities for the development of Junjia Electronics in the future. In order to meet such expected market demand, Junjia Electronics has established two production factories in Shaoguan in advance, and is expected to purchase its own factory in a science and technology innovation park in Qingxi, Dongguan this year.

Junjia Electronics is building a learning oriented company, providing regular training and learning for executives and ordinary grassroots employees to create a learning organization. Gong Changhong believes that talent is the most valuable asset of an enterprise. Therefore, in recent years, the focus of their development has been on building a good team in order to attract more outstanding talents to join.

Gong Changhong expressed his expectations for the next development of the enterprise, hoping to attract more customers who have a demand for high-power and ultra high power transformers, cooperate with them, and let Junjia Electronics' carefully developed high-power planar transformers play their strengths, contribute to human safety, health, high efficiency, and energy-saving electricity use, provide customers with creative products and services, and create a platform for co creation, win-win and sharing!

Junjia Electronics is participating in the 9th Greater China Electronic Transformer, Inductor, and Power Adapter Industry Annual Awards in 2021. Below are the voting QR codes for the two awards in which the company participated. If you think the company is excellent, you can scan the code to vote in support.
