Multilayer PCB

Features of Multilayer PCB 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 lines, the 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. 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 lines are 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.
