[High-tech LED reporter / Liu Pingping] " We exhibited a bulb lamp aluminum substrate, COB aluminum substrate, COB copper substrate, double-sided aluminum substrate and some glass fiber boards." Dongguan Kaichen Electronics Co., Ltd. (hereinafter referred to as Zhang Huaijun, general manager of "Kain Chen Electronics".
Founded in 2008, Kaichen Electronics specializes in the production of aluminum-based circuit boards and multi-layer laminates. It is designed to have a capacity of 500,000 square feet and an aluminum-based circuit board of 300,000 square feet.
Zhang Huaijun introduced that in the past, Kaichen Electronics' circuit board was mainly designed for SMD package form. In recent years, with the rise of COB packaging, the demand for COB substrates has increased, and the shipments of Kaichen Electronics COB substrates have gradually increased.
It is understood that compared with the SMD package, the COB substrate has high technical content and is difficult to process. The COB substrate belongs to a double-sided metal sandwich panel with lines on both sides, and a metal material such as aluminum/copper is inlaid in the middle, which is pressed together, which is equivalent to a three-dimensional circuit board.
Zhang Huaijun said, "Our factory was predecessor for multi-layer lamination. We have an advantage in this respect both in terms of equipment and experience."

“The advantage of equipment is only one aspect of our trust in customers. The most important thing is the emphasis on quality.†Zhang Huaijun said that in order to ensure the quality of the products, Kaichen Electronics has very high requirements for sheet suppliers.
“We strongly demand that the materials supplied by the sheet suppliers meet the standards we need. The definition of aluminum substrates is in terms of withstand voltage and thermal conductivity. We require a withstand voltage of 4,000 and a thermal conductivity of 1.0.†Kaichen Electronics will occasionally get Taiwan Lianmao Electronics Co., Ltd. for testing.
Due to the high quality of Kaichen Electronics and the recovery of the LED market this year, the order volume of Kaichen Electronics has increased dramatically, and the monthly shipments can reach 25,000 square meters.
