As a professional PCB manufacturer, we have factories in Guangdong, Jiangxi, and Hunan, using advanced production equipment to ensure the high quality of our products. We have 10 PCB production e machine works 24 hours a day, only to provide customers multilayer metal core PCB with satisfactory delivery time. In addition, all our products have obtained ISO-9001 quality system certification, ISO-14001 environmental system certification, and UL certification. SPEEDAPCB has been focusing on various single side PCB, double-sided PCB, and multilayers PCB manufacturing.
Â
PCB multilayer board simply means that more single and double boards are used to alternate the insulation material and the positioning system, and then the interconnected to form a multilayer circuit board. For example, one double board is used as the inner layer and two single boards are used as the inner layer. The inner layer is a four-layer board formed by technology.
The design of the multilayer board is more flexible and the electrical performance is more stable and reliable. At present, the most multi-layer boards used in various industries are still four or six-layer boards, and the consumer electronics industry uses more high-level PCB boards.
