Features:
1. The integration of the board design is very high, the thickness-to-diameter ratio exceeds 10:1, and the difficulty of electroplating of copper is high.
2. Made of TG140 material
Shenzhen XMD Circuits Co.,Ltd, previously known as Jaleny(jlypcb), was founded in 2009 and started the journey of circuit board in Shenzhen,China. Through the introduction of advanced production and testing equipment and technical exchanges with factories in the same industry and engineering colleges, XMD greatly expanded the process capacity of double-sided board and multi-layer board. In 2011, we began to explore overseas markets and export foreign orders to all parts of the world. In 2018, Jiangxi Ji'an added a new production line, mainly making batch orders.
