DESCRIPTIONPCBWay is a company of Chinese origin that offers high quality manufacturing services of PCBs in prototype and productionIn this document I will show printed circuits that have been made in PCBWay.MY EXPERIENCE IN PCBWAYWhen Anson Bao contacted me via Facebook I was surprised, because I did not plan to do business with people from other countries, I was scared, I thought about my money and I asked me "will they be thieves?" However, after a while I decided to pay to PCBWay, with too much fear I hired the services of this company.They guided me and explained how to pay. They are very understanding, very patient, they make the client feel very good.When I first saw the production process of my PCBs, I was happy because I was doing business with responsible people. After 3 days I received the tracking number of the shipment, after 1 and a half months, I received the printed circuits in my house; I was surprised and fascinated, excellent work, excellent quality, beautiful and very functional.After this first experience, I totally trust PCBWay, so I want to show some printed circuits designed by me and manufactured by PCBWay.Half-Bridge Boost Power Factor Corrector power stage v1Figure 1: HBBPFC power stage PCB v1.Half-Bridge Boost Power Factor Corrector power stage v2Figure 2: HBBPFC power stage PCB v2.HBBPFC's conditional signals v1Figure 3: HBBPFC's contiional signals and control stage PCB v1.HBBPFC's conditional signals v2Figure 4: HBBPFC's contiional signals and control stage PCB v2.Multiple supply voltage based on a single inputFigure 5: multiple supply voltage based on a single input PCB.Hysteretic stageFigure 6: Hysteretic control stage PCB.Words to PCBWayThank you PCBWay and Anson Bao for manufacturing the PCBs and helping me.

DESCRIPTIONPower factor correctors or PFCs are developed as a solution to power consumption problems due to their high power factor, protect systems against voltage fluctuations and high currents [1], [2].The purpose of a PFC is that the input current follows the sinusoidal form of the line voltage, so that its unit power factor is obtained [1], [2].The new HBBPFC is a converter designed to obtain 450VDC output (400VDC in the first converter), powered from the mains and obtaining a power factor PF = 1.FIRST DESIGNThis project has three printed circuits designed in Altium Designer, the first, the power stage or HBBPFC, the second, the signal conditioning stage with the control stage and, finally, the supply stage and its implementations were:Figure 1: HBBPFC international project global implementation.EXPERIMENTAL RESULTSThe following figures correspond to some of the results obtained in the implementation of the HBBPFC:Figure 2: HBBPFC international project global testing [1].Figure 3: HBBPFC international project Power Factor visualization [1].Output voltage (vs) = 212.3 + 212.7 = 425VPF = 1.Power output = 83W.NEW DESIGNIn [3] a new design of the signal conditioning PCB was proposed because the DSP used for the implementation of the control stage was obsolete, for this reason, PSoC creator became the new programming environment to develop the controller of the HBBPFC, with a development card based on FPGA with reference CY8CKIT-059 PSoC 5LP CY8C5888LTI_LP097.When changing the programming environment, the operating point of the HBBPFC was changed, increasing its voltage to 450VDC maintaining the power factor (PF = 1). The new implementation of this rectifier with power factor correction is observed in detail below:Figure 4: HBBPFC new implementation side view.Figure 5: HBBPFC new implementation top view.Figure 6: HBBPFC new implementation global view.In the upper part is the printed circuit that has the supply of voltages and the control stage (signal conditioning included), the other PCB is the power circuit (topology of the HBBPFC) and the lower part is the resistive load.With this new design, the result is a unit power factor with a power greater than 100W, as shown in the following figures:Figure 7: waveform of the current and input voltage with measurement of power factor and power of the converter.Figure 8: output voltage of HBBPFC.In summary, with the new design of the HBBPFC the power of the converter is increased maintaining its control of power factor.

Hello,My name is Luana and I am Current working on the development of a active magnetic bearing. I would like some financial support on the PCB prototype development.Bellow are finit element simulation on the bearing, and now I want to build a prototype.I would like a sort of coupoum so that I can work on my prototype. Futher I will make lager purchase and the project is done, that is why I would like to save the most with the prototype.

DESCRIPTIONPower factor correctors or PFCs are developed as a solution to power consumption problems due to their high power factor, protect systems against voltage fluctuations and high currents [1], [2].The purpose of a PFC is that the input current follows the sinusoidal form of the line voltage, so that its unit power factor is obtained [1], [2].The HBBPFC is a converter designed to obtain 400VDC output, powered from the mains and obtaining a power factor PF = 1 (see results here) [1], [2].To carry out the control step a Texas Instruments DSP (TMDX28069USB or Piccolo™ F28069) is used [3], [4], [5], [6]. This development card is observed in detail below:Figure 1: Piccolo™ F28069 [1]The Piccolo™ F28069 is obsolete, for that reason, the conditioning stage must be redesigned.OLD CONDITIONING STAGEOver time, many PCBs have been made from the signal conditioning stage. The first PCB is shown below:Figure 2: signal conditioning stage first PCB.This PCB has protection by galvanic isolated. The second version of that was a better design. As shown in the following figure:Figure 3: signal conditioning stage second PCB.Nevertheless, both PCBs did not function well because the drastic reduction in all signals caused by the galvanic isolated protection was the main problem. For this reason, the conditioning signal was redesigned from a new control diagram.Figure 4: control diagram applicated for a HBBPFC international project [1].From that diagram another PCB is created without the galvanic isolated protection, avoiding the problem mentioned above. This printed circuit board is:Figure 5: signal conditioning stage third PCB [1], [2].Because the Piccolo™ F28069 is obsolete, the signal conditioning stage shall never use more, therefore, it's created a new version that consists in change the microcontroller for a FPGA with reference CY8CKIT-059 PSoC 5LP CY8C5888LTI_LP097. This development board has digital and analog devices incorporated reducing the number of external components and simplify the design with the same control diagram (shown in the figure 4). That PCB include the supply stage and is observed below:Figure 6: signal conditioning stage new PCB.This PCB is perfectly assembled with the current HBBPFC power stage shown below:Figure 7: HBBPFC power stage.REFERENCES[1] A.

I am a power electronic matster student at Universidade Federal do Rio de Janeiro, in Brazil. I am currently working a Cascaded Doubly-fed Indunction Machine, foucousing on wind energy conversion.For this project I will need many sensors and converter borad in order to control these machines. I am working on the bench to make it possible to control the machine and aquire all the data I need. It means that I will need a lot of PCB, I need 9 current sensing, 6 voltage sensing, the torque transuder signal conditioner board and also for the speed encoder. Unfortunatelly the University is going through a crisis due ours gouvernements problems, in this way I have to bear the costs my self, or stop the project. I love to do what I do and I am trying to reduce the costs at the most to make it possible for me to pay for this.I write papers for congresses and I can use the papers to make a sort of propaganda to PcbWay.Regards

About Our TeamWe are a team from Federal University of Rio Grande do Norte, Brazil/RN, formed by undergraduate students who developers a Baja Off-road car to race on Baja SAE competitions every year on Brazil. We are one of the top 10 teams on Brazil, in the last competition (2017), we have placed 5th in overall with a total o 7 trophies. Like the others, events sponsored by SAE, like Formula SAE, Aero Design SAE, we have to develop one embedded system to our vehicle to acquire data, online or offline. We represents our state (Rio Grande do Norte - RN) on national-level Baja SAE competition here in Brasil. All of our team are undergraduate students in mechanical/mechatronics engineering. Also, we are one of the oldest team on Brasil, founded in 1995, we have two national champions (1998 and 2001, first place) and we were the first Brazilian team to win the international Baja SAE competition in 1998. About Our ProjectFor this competition year, we are planning to develop 4 PCB for our embedded system, each PCB (as we call, electronic control unit, or just ECU) is responsible for certain part of the car. For example, the rear ECU acquires the speed and RPM of the car, among temperature and gas level. The front ECU acquires front-suspension positions and minor data. The data logger ECU, as the name says, saves all the data collected and storages on a SD card, and send it via Xbee to a computer in almost-real time. For last but not least, the steering ECU shows to the pilot all-important data to see on real time race (such as speed and rpm).As the others SAE Collegiate Design Series, we have to project and build an prototype with some subsystems, including a embedded system. Now, for the embedded system, we've placed the 5th on this subsystem presentation. Some pictures of our embedded system project:Our dashboard, integrated on carbon-fiber steering wheel, made by us. Our PCBs for this year has two layers and does not pass the size of 100 x 100 mm; we do our best for developing the smallest and compact PCB for each ECU. This one is the dashboard ECU, it stays inside the steering wheel, among the display and tachometer. It has a integrated buzzer to alert the pilot in some situations, also it is responsible for receiving data and showing on the 2.4" display. In the picture below, we have the rear ECU (top) and the front ECU (bottom). The first one reads speed, rpm and gasoline level on the tank. The second one does many things (we call it the central ECU). One of the most important things that the central ECU does is to send in real time all the data collected from the embedded system to one computer on the team's box (not in picture, but the central ECU also have a GPS integrated).So, with this electronic, we've placed a top 5 in electronics project and 3th in comfort. But, as you can see, our electronic is very simple, all PCB are one sided cooper and are made by a very poor CNC. For this year project, we are planing to make a step over: starting using 2-layer PCB and some SMD components, and applying a more robust manufacturing, so we can spend more time with actually real test besides spending days searching for a broken trace or bad contact on our CNC PCB. Other thing is, as you can see too, we have a distributed system, and for this year our team are going to race with 2 cars. One goal for this year is testing for real a Centralized Vs Distributed embedded system, therefore, besides the four ECUs, we are projecting a centralized ECU to be installed on our second car.Some specs of our 2017 PCBs: We have maintained the amount of pcbs on the first car ( four pcbs); and for they, these are the specs (with quantity and dimensions) of the boards that we are looking to build through you:- Datalogger: Qty 5, 2 layer, 70 x 90 mm- Dashboard: Qty 5, 2 layer, 85 x 50 mm- Front ECU: Qty 5, 2 layer, 50 x 50 mm- Rear ECU: Qty 5, 2 layer, 50 x 64 mmAnd for the second car:- Centralized: Qty 5, 2 layer, 86 x 75 mmWe are starting to work with SMD components and 2 layers PCB, but this kind of technology is very scarce on our country, only two or three companies produces 2-layer PCB, but none of them has metalized pin (vias), so it make to us very difficult to work with these technologies. We hope, with your sponsors, the possibility to improve our embedded system and grow up more and more on our project, to stay as competitive as possible to get the 1th place! Best regards,M.

Competition Introduction with related photos: Our team participates the RoboCUP (//www.robocup.org/) and CBR (//www.cbrobotica.org) universitaries competitions, in the Small Size League (//wiki.robocup.org/wiki/Small_Size_League), Small Size League RoboCup is a competition domain designed to advance robotics and AI research through a friendly competition. Small Size robot soccer is one of the RoboCup league divisions. Small Size robot soccer, or F180 as it is otherwise known, focuses on the problem of intelligent multi-agent cooperation and control in a highly dynamic environment with a hybrid centralized/distributed system. of six robots each. Each robot must conform to the dimensions as specified in the F180 rules: the robot must fit within an 180 mm diameter circle and must be no higher than 15 cm. The robots play soccer with an orange golf ball on a green carpeted field that is 9 m long by 6 m wide. All objects on the field are tracked by a standardized vision system that processes the data provided by two cameras that are attached to a camera bar located 4 m above the playing surface. The vision system - called SSL-Vision - is an open source project maintained by the league’s community. Off-field computers are used to communicate referee commands and position information to the robots. Typically, these computers also perform most, if not all, of the processing required for coordination and control of the robots. Communications is wireless and typically uses dedicated commercial FM transmitter/receiver units. Building a successful team requires clever design, implementation and integration of many hardware and software sub-components into a robustly functioning whole making Small Size robot soccer a very interesting and challenging domain for research and education. Community Introduction with related Community activity photos: Our community is a robotics team RoboIME (www.roboime.com.br), that is part of the laboratory of robotics and artificial intelligence of the Militar Institute of technology (www.ime.eb.br), we have already taken part of some competitions like: LARC 2010 OBR 2011 RoboCUP 2012 RoboCUP 2013 OBR 2014 ROBOCUP 2014 And have already achived some results like: In 2011 we were vice-champions of Latin American Robotics Competition (LARC). In 2012 we were the vice-champion na Latin American Robotics Competition (LARC) In 2014 we were in received the fourth place in Latin American Robotics Competition (LARC) BENEFITS： Target market exposure: Logo in the sponsors area on our team’s site (//www.roboime.com.br/), Logo in the competition banner, Post in our facebook: https://www.facebook.com/roboime/ Contact with brazilian’s market Contact to Brasil’s young engineering talents working in the project, Project Introduction: Embedded System RoboIME electronics consist of nine boards: (a) the Main board, responsible for communication between the other boards; (b) the Stamp board, responsible for the embedded computations; (c) the Kicker board, responsible for maintaining high voltage and activate the kickers; (d) five motor controller boards which are responsible for the robot’s motion control and the dribbling device. (e)Transceiver board, which is responsible for the link between the robot and the main computer. Looking forward to participate this year’s LARC competition, we aim to upgrade the project by enhancing the electronic design. We are making the layout of all boards from scratch, starting for the main boar and motor controller board, using a new platform, the altium designer, and paying much more attention to details like the routing dimensions. We are also changing the assembly process that used to be manual, trying to use an automatic pick and place, the NEODEN TM245PA. Project Details The Main Board This board features a socket to plug the boards in: the kicker’s sensor, a optical sensor that is used to detect if the robot is with the ball possession, dribbler motor, which makes possible to the robot to spin and to move backward without lose the ball, four wheels’ motors, four quadrature encoders and the power supply with safety devices. We are making some changes on this board like substituting the former true hole fuses and capacitor for newer smt resettable fuses and smt capacitors, and adding a current sensor the ina220 to have a precise real time feedback of the current that flows in each motor. We are also adding a connector to the NRF24 transceiver and making an experience with a bulk voltage regulator. Stamp Board This board is responsible for performing all the logical functions. Serving as a brain of sorts for the electronic system. There is an embedded STM32F407VG micro-controller, with an ARM Cortex M4 as main CPU, 1 MB Flash, 192 KB RAM memory, working at 168 MHz, that was programmed in C language using CoIDE and Eclipse IDEs. The main function of the embedded system is to receive the data from the AI and convert it into movement. So, there is a Proportional Derivative Integrative Control sampling the real wheel’s velocity, comparing with the desired and outputting the appropriate voltage to the motor. That control has the fundamental importance of look for the right wheel’s velocity. There is also a current control that doesn’t permit the Motor Controller Board to burn out. Kicker Board This board is responsible for produce the high voltage used to activate the two coils, controlling the kick strength and discharge almost instantly all the power stored on the coils. There are two kinds of kick, the forward kick and the high kick. There are two steps in this board: charge and discharge. The first has the unique function of keep a constant output of 180V DC from a input of 7 8V DC. A DC-DC step-up power supply controlled by the MC34063 IC and two electrolytic capacitors of 2200 μF, 200 V are used for this task. The second is to drive the kickers. In this part are used one TC4427 Mosfet Driver IC and two IRFP4868PBF Power Mosfet that are responsible for close the high voltage circuit of the first step with the ground through the coil, converting electrical into mechanical energy. A precise control of the actuation time ensure that the kick will occur with the right velocity. Motor Controller Board: The idea of the RoboIME electronic is to modularize the electronic project. So, there is one controller module board for each wheel motor. If one of them burns out, it is possible to exchange it quickly. Each board has two TC4427 (MOSFET driver) and two IRF7319 (complementary half H bridge). These ICs create an H-bridge, allowing the velocity control in both directions through a Pulse-Width Modulation, converting a digital signal input into an analog output. Transceiver Board The transceiver board is responsible for the link between the micro-controller and the main computer through a NRF24L01 transceiver. The first is done using a own protocol, operating in the 2,4 GHz band, the second is accomplished through the Serial Peripheral Interface Bus (SPI), a standard.
