Analyse Schematics and PCB layout to find issues -- 2

Hi Sir I have seen your project. I can help you get it rectified. I have more than 7 years of experience. Please share the altium files I have more than 130 project completed here and have done a lot of work with altium. Please get in touch to discuss it further Regards ALi

Greetings, I have good experience with circuits specifically in power supply, battery charging/management. I think I can help you here. Please see my profile/portfolio for my experience. However I don't have Altium license so I can help you with finding the issue only. Schematic & Layout update you will have to manage on your own. All I need is the schematic pdf and gerber files. Let me know if you would like me to assist you. Look forward to hear from you. T & R Alok Pugalia

Hello, I have been associated with Hardware design (Circuit / Electronics design), PCB design, Library creation and Library database maintenance, PCB Manufacturing, Component procurement, PCB Assembling and Functional testing for over 9 years. I have used various CAD/EDA tools for PCB design. I'm having good experience in Altium designer. I will provide the PCB Manufacturing, Component procurement, PCB Assembling & Functional testing services too. I would like to take this up and are fully equipped to deliver the required files. So, if you'll give me a chance to take part to your work, I will respond in the same manner, handling you good quality projects, as soon as possible. I look forward to hearing from you! Wish you a nice day! Thanks & Regards, Karthik

Hi! I've saw your post regarding the project and I can help you with your issues. I've work also in Altium Designer so will be easy for see the problem on the schematics and on the PCB. I've done many projects regarding complex circuits with memory, SATA, SoC, so will not be a problem for me this project. If you need more details regarding my projects please let me know on the chat. Thanks! Adrian

Altium designer pro here. Seems you've already found the problem (power supply?) so I'm here to turn it into a solution, haha. Anyway, would need to look at the files, but can give you a general overview of what else might be suboptimal, and no problem to redo power supply with whatever specs you need. Drop a message if any questions, capabilities are listed in user profile. Payment only after everything is delivered and agreed/confirmed that new changes work.

Dear Valued Employer, My name is Martin Botsov and I am an engineering physicist with extensive experience in the field of circuit design, circuit prototyping and PCB design. As I understand from the project description you are looking for a hardware engineer capable of providing technical feedback and design improvement ideas for an already existing prototype PCB. So, without further ado here's how the workflow would look like, if you happen to choose me as a partner for your project: 1. Initial discussion 2. Review existing schematics and layout 3. Feedback on existing schematics and layout 4. Schematic update (if where/neccessary) 5. Component library creation (if neccessary) 5.1 Schematic symbol library creation 5.2 Footprint library creation 6. Schematic drawings 7. Review of final schematic drawing 8. Layout design update (if where/neccessary) 8.1 Components placement and arrangement 8.2 Review of proposed layout design arrangement 8.3 Components routing 8.4 Review of final layout design 9. Design rule check 10. Verification and validation 11. Production files (GERBER, NC DRILL, BOM, ASM, PICK & PLACE, SCH, STEP) Your project will be carried out on Altium Designer. Don't hesitate to contact me with questions regarding any details around your project. You could also check out my profile on Freelancer and LinkedIn for more details around my professional experience. I am looking forward to hearing from you soon. Thank you for your time. Kind Regards Martin Botsov

Hello, contact me for high quality work delivered on time. I will work on you paper personally since i do not outsource some of the writers will outsource your paper which might delay the delivery time , this guarantees you to high quality work and you can request for revisions till your fully satisfied with the work. I believe writing is a passion and not money making business where people will deliver low quality work just to get paid. Try my services and you will never regret. Waiting for your kind response.

Hi I'm Tra from VietNam. I hope we can work together in this project or any other project in future. I'm looking forward to chat with you for further information and get files to review. Regards Tra

Hi, I am an Electronics Engineer and works in a good firm as an designer . I have 5 years of experience in making PCB's. I have skimmed your project details and it is very easy for me to do. In my PCB designs I will provide you with the following aspects to ensure quality of the PCB. 1) Power and Ground plane. 2) Fully tested and Functional on simulators. 3) Proper Calculation of track size according to the Max load current. 4) Proper stacking up all layers so that characteristic impedance can be as low as possible. 5) Proper consideration of via types and their current handling capabilities. 6) Proper take care of design rules like component placement, crosstalk budgets, layer allocation, length matching/time of flight analysis, and so on. 7) Proper verification of the signal and power integrity, this must first ensure that the breakout and route all of the signals on high-pin-count devices. This will also affect the stack-up of the PCB. 8) Proper consideration of Signal Integrity and Power integrity such as signal rise and fall times, track lengths and characteristic impedances, and the drive strength and slew rates of the drivers and terminations. I have some samples of my work which will be provided upon request. I will provide you quality work on reasonable rates. Please contact me as soon as possible. Looking forward to work with you.

I will do the complete hardware (NOT FIRMWARE debugging) design check and recommend possible layout fixes if that's the case, and if needed to make a complete pcb redesign I will do it & deliver to you both schematic & pcb drawing as pdf for reference & correcting your design, and of course the GERBER & NCDRILL & BOM ready for PCBA, files needed to make production of your project. However I do prefer not to work for this with Altium, although I have it and occasionally working with it (mostly for minor upadets of some of my standard customers boards that I do production for them, with my pick & place machine). Gerbers might be also usefull, as I can see fast enough if there is a cardinal mistake on the layout of your pcb, since this an RF related design, and there may be some RFI issues on the layout, that makes the uCU rebooting, during large RF usage. If a redesign of the board is essential I will prefer to do it using the more powerful Easy-PC professional CAD (Number One system UK) that I'm using for more than 25 years, since their DOS version (or if you prefer to be able in the future to modify the design without paying anything for specific CAD programs, in the real NO COST freeware, but not so pro-looking, similar CAD named Design-Spark that is freely available from RS Components, & it is a COMPLETE CAD with everything available for design and production output). Feel free to contact me for anything you may want to discuss. Sotiris Papadimitriou
