When the home sweeping robot is in operation, it will often be "trapped" and unable to move. In response to this problem, Xiaobing told everyone today why they are "trapped" and the solution. I hope that those who have encountered similar problems can learn.
The intelligent mode of the intelligent sweeping robot is nothing more than the intelligent system of its main board, but its hardware can not fully simulate the human skeleton, and the muscles operate. After all, the robot is still dead. There are several common types of sweeping robots that are trapped:
1. The robot is wrapped around the wire.
The 21st century is already the age of electrical appliances. There are wires in the refrigerators, plug-in boards, TV sets, etc. in the home. If there are too many wires, the robot will be entangled in the cleaning process.
2. The robot is wrapped around the edge of the curtain or carpet.
During the operation of the robot, the places that are often entangled are also under the curtains, on the edge of the carpet, etc. These edges must not be sucked into the integrated box, but mislead the robot to think that it is capable of sucking up the garbage, causing jamming and entanglement. occur.
3, too many obstacles lead to
Too many obstacles are also one of the main reasons for the robot to be trapped. For example, in a dead corner, the stool is too dense and the operation of the robot is mistaken into it, which may cause the robot to enter and return.
Solution: The reasons for the above three reasons are trapped or hindered. Under normal circumstances, the sweeping robot will intelligently find a solution. If the robot can't get rid of the trouble, we need to manually help the sweeper. Get the thread.
Usually,10 & 20 layers PCB are HDI board,but some are not .Some with big trace width and space,holes are over 0.3mm too. We have much experience in doing 10 layer PCB & 20 layer PCB.
A ten-layer board should be used when six routing layers are required. Ten-layer boards, therefore, usually have six signal layers and four planes. Having more than six signal layers on a ten-layer board is not recommended. Ten-layers is also the largest number of layers that can usually be conveniently fabricated in a 0.062" thick board. Occasionally you will see a twelve-layer board fabricated as a 0.062" thick board, but the number of fabricators capable of producing it are limited..
High layer count boards (ten +) require thin dielectrics (typically 0.006" or less on a 0.062" thick board) and therefore they automatically have tight coupling between layers. When properly stacked and routed they can meet all of our objectives and will have excellent EMC performance and signal integrity.
A very common and nearly ideal stack-up for a ten-layer board is shown in Figure 12. The reason that this stack-up has such good performance is the tight coupling of the signal and return planes, the shielding of the high-speed signal layers, the existence of multiple ground planes, as well as a tightly coupled power/ground plane pair in the center of the board. High-speed signals normally would be routed on the signal layers buried between planes (layers 3-4 and 7-8 in this case).
