4层FR4 PCB
FR4材料和性能FR4是NEMA(美国电气制造商协会)定义的玻璃纤维增强环氧化合物的标准。FR是英文“flame retardant”的意思,表示该材料符合可燃性标准。
我们制造了一块板厚为 1.6 mm、铜厚为 1 OZ 的 10 层 FR4 PCB。 这些 PCB 的最小孔径为 500 万,最小线宽为 400 万。 这些 PCB 没有丝印,但有绿色阻焊层。
分类:固态硬盘的存储介质有两种,一种是采用闪存(FLASH芯片)作为存储介质,另一种是采用DRAM作为存储介质。 最新的是英特尔的 XPoint 粒子技术。

智能家居系统的所有节点控制模块通过RS485家庭控制总线与系统信息控制中心相连,遵循统一的家庭控制网络通信协议,实现系统数据通信。
可穿戴设备应该有两个最重要的特性:一是长期可穿戴,二是智能化。 可穿戴设备必须持续佩戴在人体上,才能带来提升用户体验的效果。
所谓SSD就是固态硬盘。 硬盘一般分为两种,一种是机械硬盘,一种是固态硬盘。 固态硬盘是由固态电介质制成的硬盘驱动器
Printed circuit boards or PCBs are key components of electronic components. Most people use them every day without even thinking about it, and they are vital to all walks of life. There are tons of applications for PCBs, but we'll cover 10 of the most com
KINGFORG PCB assembly manufacturers for you to explain-How much do you know about the PCB assembly process?
A multilayer PCB is a printed circuit board with more than 2 layers. Double-sided PCBs have two conductive layers on the top and bottom of the PCB substrate. Multilayer PCBs must have at least 3 layers of conductive material or copper. All layers are inte
The digital world is getting more complex every hour, and the hardware associated with it is getting smaller. The advantages of HDI PCBs are many, starting with more interconnects in a smaller area. This leads to miniaturization of circuit boards that can
Open almost any electronic product and inside is a printed circuit board (PCB). The board provides the mechanical mounting for the electronic components that make up the design and the electrical connections between them. Commonly used in the electronics
