content: I would like to announce that I design the PCB layout project in one layer, two layers or four layers. PCB projects can be used to manufacture PCB prototypes or large amounts of PCBs.PCB layout projects can be presented in the following form:PDF files + Gerber 274X files, if you want to build PCB's in multiple copies to a specialized company + your prototype. Gerber format is 274X and is a format supported by many PCB manufacturers.PCB projects are made keeping in mind the standard IPC2221.The cost of developing a project will be:1) for circuits that operate in the frequency range0 ... 20kHz=10...15 USD / hourdepends on the complexity of the circuit.2) For circuits that operate in the frequency range20kHz ... 1GhHzcost will be:2 layers PCB project:Proiect Cost =15....25 USD / hourdepends on the complexity of the circuit4 layers PCB project:Proiect Cost =20...50 USD / hourdepends on the complexity of the circuitNote the following: To develop a PCB layout project I will have to reproduce circuit diagram of the project in my software (informative, this process depends on the complexity of the schematic, it can take between 25 ... 60% of the time required to complete the PCB layout project, because we have built in some cases, new PCB footprint).ATTENTION!My PCB projects using PCB netlist. So, from this point of view PCB will follow as closely circuit diagram. This is a big advantage.VERY IMPORTANT:A.To tell you the exact price please send me your final version of the electronic schematic. The final version of the schematic is enough to have namely the wattage resistors and voltage capacitors, because I'll numbered electronic parts. Also, in the final schematic, please specify the integrated circuits package (DIP8, SOP14 ...), as well as their name because I need to know the numbering and name pins. So, is no need to tell me the values of the capacitors and resistors - not mandatory - that to protect your project, but the name must be specified for each integrated circuit and electronic component is SMD or THT (this must be specified for any electronic components directly on the diagram or schematic sent to me).In this step I recommend you send me an excel file with what I said above.B.Regarding the location of the connectors and what types of connectors you plan to use, you must send me a JPG image with the arrangement of these connectors and where you want to be placed holes for mounting PCB. In that picture it is necessary to present some significant share (distance holes from the margins PCB, mounting hole diameter - ie diameter 3.2 mm is typical - distances of the connectors to the PCB edges or margins…). At this stage you can send me and a PCB shape (or what is the desired format of the PCB board). I will analyze the format and tell you if it can fit in those dimensions circuit diagram. If don’t fit, then agreed with you, I'll take some decisions about the components used (ie if I use only THT or SMD components or both).C.Performing design will cover three stages or phases:1. In the first phase of the project, after you send me the final version (including what I said in paragraphs A and B above), I communicate your project cost and period of the design (or timing of development of the design). If you agree, then move on to second part below.2. In the second part of the project, as things evolve right (example: we agreed on the price of the project), after you send me the final version of the schematic, I'll reproduce that schematic. To do this, you must pay in advance 10…50% of the project cost. So, you have to make payment through Pay-Pal, 10…50% of the project cost to redesign schematic (paypal fees are paid by the customer) and start PCB layout design. After I reproducing circuit diagram, I'll send you the PDF version of it to analyze (with 3D PCB Preview). Then you can do some corrections or additions (improvements) before moving effective to PCB layout routing.3. In the third part of the project will begin the actual design of the PCB. The remaining project cost can be paid within 1, 2 or 3 installments (or rates). Pay an installment involves continuous design. In the third stage does not allow schematic changes - is permitted only small changes in PCB fotoprint of active electronic components (like transistors or integrated circuits, but not resistors or capacitors).For further details, additional information or questions, please post them in this topic or send me a private message:here, oneevblog.com/forum/or my websitewww.tehnium-azi.roor my e-mail:donpetru- at -gmaildotcomI recommend you use my email address if you want to communicate quickly.Payment will be made in advance through pay-pal after a preliminary discussion in which we establish conditions for project delivery and project execution time.I assure the confidentiality of schematic submitted and that:I don't allow you to specify the values of passive components (like resistors and capacitors), plus it guarantees, that the confidentiality of the project.!!!!!!!!!!!!!!!!!!!! If you want the project development in a professional setting you can find me on elance.com com under user-name: PETRISOR D. But there the price for design will be higher. However, you do not have to worry because I am an honest person (known in many technical forums), but it's your choice, so you can call both ways: through this forum or using the website elance.com. I will give all my experience practice for PCB layout project results to be very useful and will bring money to you.UPDATE: 19 february 2014:If you want to develop projects of commercial audio amplifiers, I can provide support for:- schematic amplifier design;- improving the technical performance of the amplifier;- construction and prototype testing and much more.All these things can be negotiated with prices between: 10 and 25 USD / hour.I can also offer PCB layout services for boards from old audio amplifiers, if you want to refurbish them and it is necessary to create other new PCBs. The price is between 10...20 USD/hour for creating PCB layout and Gerber files.LAST UPDATE - 29 december 2023:I change price for PCB layout design.

content: i have a schematic consisting of 4 connectors , 2900 pins each and 3 decoupling caps ... so it's 3$ right ? (less than 5 connectors )on parts selection : how do you know what size to pick for the components. if i tell you 1000uf 25 volt you have no idea if it is a 10mmx25 a 12x22 a 25x10 or any other size.same for resistors. same for ceramic caps. i want all my ceramic or film caps to be 5mm pitch , but the width of these can change.i also wonder how you make 3 layer boards ....

content: Today I saw the answers above. Unfortunately I forgot to switched to favorites this topic in this forum.Quote from: free_electron on December 18, 2013, 08:04:05 pmI do not understand irony. When I refer to the connectors, I mean the connectors used with up to 20 pins. For other types of connectors quote is calculated accordingly. Anyway, it's good that you asked. It may be, and such offer, but that does not mean is 3$ .What I did not say above is that you have to show me an excel file that includes the numbering of components and their footprints (constructive dimensions). But issues like this is understood.And PCB usually runs in a single layer, 2 or 4 layers.Quote from: c4757p on December 18, 2013, 08:11:57 pmYes, you do not you believe it that.And beware:price = part x 1 USD; is PDF format (the audio field), delivery format that does not include drilling gerber file, only PDF with information drilling (drill legend). PDF format PCB design is for those who want to achieve a single PCB (prototype) or at most a few pieces. If you wish Gerber files will have to pay twice as much.Of course, for customers who realize more PCB projects can give significant discounts for Gerber files.Then there are times when customers wanted at first only PDF, as to make the prototype. After you have tested the prototype and have made improvements, they asked me to change the PCB. The cost of amending the PCB was very small and they could then command Gerber files for large series production of PCB. So, are many customers who have chosen this strategy, because it saves time and money.

content: When I saidmeter panelI mean "ammeter voltmeter panel with LCD 1x16" connected via a connector and cable.The name initially chosen is not the best, but considering the title of the photo, it is understood what it was about.

content: Quote from: free_electron on July 09, 2014, 05:27:12 pmI said above (see first post): "For other areas thatexceedthe operating frequency of the audio spectrum". So, that means over 20kHz but no more than 1GHz. And beyond 20kHz isn't audio spectrum, as you misunderstood.Anyway, I change little my expression from the first post as not to create confusion (sorry for my english, but I think it is pointless to quarrel on this aspect).

content: At this moment I design PCB layout in maximum 4 layers (with SMD and/or THT parts) and the deliverable files are - as I said in the first topic - Gerber 274X files and PDF files. With these files, the client can build his own prototype and send the Gerber files to a PCB factory that he agrees with (it's his choice).
