There are hundreds of robot factories in China. In the small and scattered competition landscape, the second-ranked manufacturers have annual sales of less than 100 million yuan. Only the Shenyang Xinsong robot family stands out from the crowd and has an annual sales income of RMB 1.6 billion. What are the technical advantages of this largest robot factory in China? What exactly is a production plant? Reporter Lu Hongqiao recently came here for a visit.
Hello everyone, my name is Komatsu and I am a member of the family of Xinsong service robots. I am very happy to meet you at the inaugural meeting of the Chinese robot TOP10 summit...
A splendid conference was staged in Shenyang. It was a robot that hosted the conference. This is a service robot developed by Xinsong Robot Automation Co., Ltd. Although it is already an old model, the guest host does not seem to have any flaws.
The robot host is still not the protagonist. Into the factory floor, a white robot with a head-mounted screen spoke to reporters.
Robot: Meet for the first time, please take care. What business do you need to handle?
This is the manager of the robot lobby. It is mainly used in banks. It is not only able to greet and seduce. Xinan Robots Brand and Public Relations Department Minister Hahn Jingjing said that the work of human lobby managers can do almost everything.
Hahn crystal: can introduce, brush a small ticket, you can brush your face, because it is more and more advanced technology, can be identified, can be human-computer interaction. You can see that in the middle of it, you can also move something and take the guests to the designated window, which is the same as the lobby manager. It can automatically avoid, you see people there, it walks around people.
Next to the robot manager, several robots carrying trays and mineral water shuttled back and forth between the tables. Their identity is a robot attendant, also known as a food delivery robot. In fact, they can not only order meals, deliver meals, and some can also complete such technical work as bartending. In some cities, robot attendants have already “workedâ€.
Hahn Jingjing: This meal delivery is now quite mature. You also often see the robot restaurant, so it is quite convenient. The future may be combined with Alipay, as well as other ports, it may be able to check out, guests can use it to pay for dinner.
In addition, Xinsong is also developing new service robots for use in medical care, pension rehabilitation and other fields. Of course, these are now kept secret. However, at present, the company is still the best industrial robot.
In a certain area of ​​the Xinsong workshop, dozens of robotic arms are constantly waving, and the scene is quite spectacular. There are even sci-fi movies. In fact, this is a test of an industrial robot. There are fast sorting robots that can handle two hundred movements in a minute, making people dazzled; there are parallel robots, two robots can coordinate the assembly of parts; there are grinding robots, high precision, but also not afraid of dust pollution.
Hahn Crystal: For example, vision, sensing and many other new technologies we have added. Our domestic robots are now largely replacing imports, including many robots currently used by US General Motors headquarters.
6 layer PCB board is, in general, a 4 Layer PCB board with 2 extra signal layers added between the planes. The 6-layer PCB classic stackup includes 4 routing layers (2 outer layers + 2 internal layers) and 2 internal planes (one for ground and the other for power). This enhances the EMI dramatically by offering 2 buried layers for high-speed signals and 2 surface layers for routing low-speed signals. The signal layers should be closed to the adjacent planes.
6 Layer PCB Prototype Fabrication China Manufacturer
Jinghongyi PCB has been committed to the production of multi-layer PCB and prototype PCB for nearly 10 years. The largest number of multi-layer printed circuit boards for customers are 4-layer, 6-layer, 8-layer, 10 layer, 12 Layer PCB and above. In order to ensure the quality of PCB products, we constantly improve and upgrade the production process. PCB surface treatment technology has hot air leveling(HASL), OSP, electroless nickel, immersion gold, immersion silver, immersion tin and so on.
The printed circuit board is basically composed of the pad, via, solder mask layer, silkscreen layer, copper wire, and other parts. Among them, solder mask refers to the part covered by ink on PCB. Because most PCB uses green ink, the green ink part that can be seen is solder mask. The role of the solder mask in controlling the reflow welding process is very important. In addition to green ink, the welding layer can According to the different needs of customers, and can also be customized in a variety of colors, such as green, blue, black, red, white, yellow, purple. Of course, the price will vary with the color of the solder mask. Green oil is the one with low price and stable quality, which is also the reason why green oil is most used. The price of black oil, red oil, and white oil is almost the same, slightly more expensive than green oil, and the price of rare inks such as yellow and violet oil is the highest. In addition to the color of the solder resist ink, there are also matte and bright, matte ink color.

6 Layer PCB Stackup and Design
What is PCB stack UP?
PCB Stack up refers to the arrangement of copper and insulation layers that make up PCB before the layout design of circuit board. Although stacking allows you to get more circuits on a single board through various PCB layers, the structure of PCB stacking design has many other advantages:
The PCB layer stack can help you minimize circuit noise and radiation and reduce impedance and crosstalk problems in high-speed PCB layouts.
A good stacked PCB stack can also help you balance the need for low-cost, efficient manufacturing methods and focus on signal integrity issues.
Proper PCB stacking can enhance the electromagnetic compatibility of your design.
For PCB-based applications, stacked PCB configurations are usually good for you.
Why do PCBs stack up?
The irreversible development of modern electronic products has increasingly pushed PCB towards such needs as miniaturization, light weight, high speed, better functionality and reliability, and longer life, which has led to the popularity of multi-layer PCB. Two or more Single Sided PCB and/or Double Sided PCB are stacked together by a combination of semi-solid adhesives called "prepregs" to form multilayer PCBs through reliable predefined interconnections between them. There are three or more conductive layers in a Multilayer PCB, two of which are outside, and one is synthesized in an insulating board. With the increasing complexity and density of PCB, some problems may arise, such as noise.
One of the most important factors to determine the performance of product electromagnetic compatibility (EMC) is to plan the optimal multi-layer stack up. The carefully designed cascade can minimize radiation and prevent the circuit from being disturbed by external noise sources. Good stacked PCB substrates can also reduce signal crosstalk and impedance mismatch. However, poorer stacking may increase EMI radiation, because impedance mismatch will lead to reflection and ringing in the system, which will greatly reduce the performance and reliability of the product. Then, this article will focus on the layer stack definition, design rules and basic considerations.
Most six-layer PCB consist of four signal routing layers and two planes. From an EMC perspective, a 6-layer Printed circuit board is usually better than a 4 layer PCB board.
6 Layer PCB Stackup
6 layer 1.6 MM standard stackup and thickness
One stack-up NOT to use on a six-layer PCB board is the one shown in Figure 1. The planes provide no shielding for the signal layers, and two of the signal layers (1 and 6) are not adjacent to a plane. The only time this arrangement works even moderately well is if all the high frequency signals are routed on layers 2 and 5 and only very low frequency signals, or better yet no signals at all (just mounting pads), are routed on layers 1 and 6. If used, any unused area on layers 1 and 6 should be provided with "ground fill" and tied into the primary ground plane, with vias, at as many locations as possible.
Fig. 1 One of the stackup methods of 6-layer PCB
This configuration satisfies only one of our original objectives.
With six layers available the principle of providing two buried layers for high-speed signals is easily implemented as shown in Fig. 2. This configuration also provides two surface layers for routing low speed signals.
Fig. 2 Less common 6 layer PCB stackup
This is a probably the most common 6 layer PCB stack-up and can be very effective in controlling emissions, if done correctly. This configuration satisfies objectives 1, 2, & 4 but not objectives 3 & 5. Its main drawback is the separation of the power and ground planes. Due to this separation there is no significant interplane capacitance between power and ground Therefore, the decoupling must be designed very carefully to account for this fact.
Not nearly as common, but a good performing stack-up for a six-layer PCB is shown in Fig. 2.
Fig. 3 Another performing six-layer PCB board stackup
H1 indicates the horizontal routing layer for signal 1, and V1 indicates the vertical routing layer for signal 1. H2 and V2 represent the same for signal 2. This configuration has the advantage that orthogonal routed signals always reference the same plane. The disadvantage is that the signals on layer one and six are not shielded. Therefore the signal layers should be placed very close to their adjacent planes, and the desired board thickness made up by the use of a thicker center core. Typical spacing for a 0.060" thick board might be 0.005"/0.005"/0.040"/0.005"/0.005". This configuration satisfies objectives 1 and 2, but not 3, 4, or 5.
Another excellent performing six-layer PCB board stackup is shown in Fig. 4. It provides two buried signal layers and adjacent power and ground planes and satisfies all five objectives. The big disadvantage, however, is that it only has two routing layers -- so it is not often used.
Fig. 4 Another excellent performing six-layer PCB board stackup
It is easier to achieve good EMC performance with a six-layer circuit board than with a four-layer circuit board. We also have the advantage of four signal routing layers instead of being limited to just two. As was the case for 4 layer PCB boards, it is possible to satisfy four of our five objectives with a six-layer PCB. All five objectives can be satisfied if we limit ourselves to only two signal routing layers. The configurations of Figures 2, 3, and 4 all can all be made to perform very well from an EMC point of view.
