From idea to working electronic circuit board

PCB design and custom circuit board development

If you want a control board for your machine or would like to develop your own electronic product, we can start even without a circuit diagram. VOMRO manages circuit design, PCB layout, embedded software, prototyping and testing within a single project plan. We define the scope of your turnkey PCB solution together and deliver a working board with the source files and technical documentation we develop. At your request, we can work under an NDA before you share technical details.

VOMRO engineering approach

Describe what your device will do; Let's develop the technical solution together.

Saying "I want to see the sensors on my machine on a single screen" or "Let my product keep records even when the internet is disconnected" is a start. You do not need to choose a processor or draw a circuit to have an electronic circuit board made. We discuss the actions the user will take, the equipment the device will be connected to, and the result you expect. From this information we extract the connections of the board, the tasks of the software and the functions to be tested.

For example, level measurement, on-screen display, alerts and remote logging are separate functions in a tank monitoring device. We decide which belong in the first version and develop the electronics, software and, where needed, enclosure around the same objective. This makes the work and its verification clear from quotation to delivery.

Do I need a ready-made schematic to make an electronic circuit board?

No. You can start a circuit development project with a product idea, a video of your existing machine in operation or a simple drawing. Tell us where the device will operate, what it will measure and control, and your approximate quantity. We clarify any technical details you are unsure about together during the discussion and review.

If you have a schema, software or working example, we will also evaluate these. After reviewing the status and usage rights of the design documents, a scope is created to improve the existing structure or design a new circuit board.

A design that replaces a board in an existing machine must do more than fit the same dimensions. Together, we define the connections, communications and machine behaviour that must be preserved. Sharing the following information, where available, helps distinguish what can be reused from what needs to change.

What needs does the customer-specific PCB meet?

PCB is the printed circuit board that connects electronic components together. In the customer-specific PCB design, the board's size, connections, power supply and functions are determined according to your device. A box that does not fit ready-made modules, sensors that you want to combine on a single board, or a product that you will offer with your own brand may be the beginning of this work.

A machine-specific control board can read sensors, command motors or valves and exchange information with an operator display. We review the necessary connections and operating conditions together. If an off-the-shelf solution meets your needs, that option is also considered; the decision to develop a custom solution depends on functionality, production quantity and maintenance expectations.

What does the turnkey PCB solution include?

Turnkey electronic board development aims to deliver a board that performs the agreed tasks. At VOMRO, this process may include requirements analysis, circuit schematics, PCB design, component selection, prototype preparation, the necessary embedded software and functional testing. If an enclosure, display, server connection or assembly is needed, its scope is also defined at the outset.

A bare PCB, an assembled board and a programmed and tested board are different deliverables. We clearly state in the quotation which outcome you will receive. PCB fabrication and assembly support are offered only as part of customer projects developed by VOMRO.

We plan the electronic circuit and PCB design according to your usage

We determine which sensors, motors or other devices the board will be connected to. Battery or mains operation, indoor or outdoor environment, measurement frequency and connection distance affect the design. The screen, buttons, cables and mounting points are also placed according to the use of the device.

When moving from the circuit diagram to the PCB layout, we consider power requirements, heating, electrical protection and interactions between signals. Component selection covers technical suitability, availability and alternative parts. We connect design decisions to the results that will be checked on the prototype.

We test the working prototype with real usage scenarios

The components of the sample board are placed, the necessary software is installed and the first run is made. The board is then tested with the sensors, displays or loads to be used in the project. We determine acceptance criteria at the beginning of the project, such as the measurement being stable, the outputs responding correctly, and the data reaching the target.

For example, we check how the device restarts after a power outage and what happens to records when communication is lost. After the necessary improvements, the hardware revision and software version are recorded together. This establishes the conditions under which the delivered working circuit board was verified.

We address the board's software, enclosure fit and production readiness together

Embedded software enables the board to read sensors, make decisions, and communicate with connected devices. Screen interface, error recording and update functions are developed as needed. If a connection to the web panel or existing automation is desired, the information to be transferred is also defined in the same project.

In projects where cases are developed, board dimensions, connection clearances and assembly are checked together. A bill of materials, programming and testing steps are prepared for the subsequent production of the approved board. Depending on the production quantity, test apparatus and serial number tracking can also be added to the plan.

How is the price of making a custom electronic circuit board determined?

Development fees and production cost per board are separate items. Circuit and PCB design, software, prototyping and validation fall within the development scope. Subsequent production incurs costs for bare boards, components, assembly, programming and testing. The required functions, board size, prototype quantity and production quantity affect this calculation.

In your first request, you can share the function of the device, its current status and your expectations. After the technical review, a proposal containing work packages, revision steps and delivery list is prepared. Instead of giving a fixed price for a project whose scope is unclear, we explain which result will be achieved with which work.

Receive your project with source files and technical documentation

We can work with a confidentiality agreement (NDA) upon your request before sharing technical details. We do not sell the project we developed specifically for you as our own ready-made product. At the end of the project, source codes developed within the scope, editable schemas and PCB designs, mechanical CAD files and technical documents, if any, are delivered.

Gerber production deliverables, bill of materials, programming descriptions and test records are specified in the delivery list. License terms of third-party libraries and tools are explained separately. This way, you have a working board and a documented project package that you can use for maintenance, remanufacturing and subsequent development.

Frequently asked questions

Before starting the project

The technical scope, deliverables and test plan are clarified together according to the requirements of your project.

Is a turnkey PCB solution the same as bare PCB manufacturing?

These are different scopes. PCB fabrication may mean producing bare boards from existing production files. VOMRO's turnkey development approach plans circuit design, software, prototypes, testing and project file delivery together according to your needs. PCB fabrication and assembly are offered only for customer projects we develop.

Can you redesign an existing board?

If there is a technical document, working example and legal right to use, a new architecture can be evaluated for boards that are out of production or need to be improved.

Can mass production be done after the prototype?

Yes. Prototype revision is made suitable for mass production by discussing the production quantity, component supply and testing method at the beginning.

Do I need to prepare a schematic to make an electronic circuit?

No. To get started, simply explain what the device should do, where it will be used, the sensors or loads it will connect to and your expected dimensions. The circuit schematic, PCB layout and required software can be prepared as part of the engineering work.

Do you also develop software and casing along with the PCB board specific to my project?

Yes. According to the need, electronic circuit design, embedded software, operator display, communication, mechanical case and prototype are included in the same project plan. The functions to be developed and the resources to be delivered are determined in writing at the beginning.

Do you offer standalone rapid PCB manufacturing or contract PCB assembly?

We offer rapid PCB production, PCB assembly and sample preparation only for our customers whose projects we developed as VOMRO. These steps are part of our design, prototype validation and production preparation process.

Can we work with NDA before sharing technical details?

Yes. We can complete the NDA arrangements together before you share your project's technical details.

Do you deliver source codes and technical files at the end of the project?

Yes. We deliver the source codes, design files and technical documents we developed within the scope of the project to you at the end of the project. The delivery list and file formats are clarified at the beginning.

Does a working prototype mean the product is ready for sale?

A working prototype allows the agreed functions to be tested under specified conditions. The conformity assessments, external laboratory work and product documentation needed to place the product on the market must be planned separately, according to the target market and application. In the quote, we distinguish the tests included in prototype validation from work to be carried out separately; we do not present functional testing as completion of all product requirements.

How do we proceed if I want to add a new feature after delivery?

First, we distinguish a shortfall in the agreed functions from a new requirement. We assess the hardware, software and retesting needed for the new feature, and clarify the scope, schedule and cost before work starts. The delivered source files can form the basis for further development, but not every new feature can necessarily be implemented on the existing board through software changes alone.
