Audited Supplier 
We have professional team, using automation, digitization to greatly improve pcb production efficiency and reduce PCB procurement costs.
We do many keyboard PCB, and we also have other 61 keys, 86 keys, 101 keys, 104 keys, Win98 keyboard models. We are able to produce high quality keyboard PCB according to our customers' gerber and requirements, which will eventually be used in the keyboard assembly of Razer, Corsair, HP and BenQ brands etc. High-quality raw material, advanced production equipment, intelligent systerm, strict inspection provides users with PCB products of higher quality, more cost-effective, and faster delivery.
Specifications:
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.
