    How To Design A Barebones PCB?

    Every electronic design starts with the drawing. Besides this, there are several steps to get the final output of a barebones PCB.

    Now, we will be discussing their step-by-step design process of them.

    Drawing The Schematic

    The first step is to draw the schematic design of the barebones PCB. The schematic is for the shape of the board, component placement, routing design, and traces design.

    PCB Schematic Diagram

    PCB Schematic Diagram

    It is the foundation of PCBs.

    Designing The Layout

    The next step after successfully drawing the schematic is the PCB layout design. The layout design depends on the schematic drawing.

    To shape the layout, you need to import the SchDoc file to the designing software. To do this, you need to create a blank layout first.

    Confirming Layer Stack Up

    Confirm the layer number for your PCB. It is essential when you design a multilayer PCB.

    Printing The Layout

    Now you are ready with your layout design. So, you can go to the next step. Now you need to print your layout on the barebones PCB board.

    There are different printing methods such as 3D printing, laser printing, chemical printing, etc. You can use one of them. This video shows how 3D printing prints PCBs:

     

    Etching Conductive Traces

    The conductive traces of your barebones PCB will flow the electric current towards the PCB components. Etch the traces with proper copper.

    Component Placement

    When you customize your barebones PCB with particular functionality, you need to place the right components properly. Carefully solder the components so that no soldering-leftover sustains. Now, your customized barebones PCB is ready to function with your desired functionality.

    How Can You Solder The Barebones PCB?

    Solder masks are used on most printed circuit boards (PCBs) to avoid solder bridging, cover traces, and empty areas. You will see that the surface anticipation pushes the solder masks away from the hot solder and towards the solder pads. This occurs as a result of the reflow procedure.

    However, the reality remains that the barebones PCB does not have any solder masks. Because the solder does not include solder masks, solder bridges may form on the PCB pads.

    Be Careful While Soldering The Barebones PCB

    Be Careful While Soldering The Barebones PCB

    As a result, you must exercise caution throughout the soldering process. Make sure that the solder paste is evenly distributed throughout the circuit boards. In addition, you may solder by hand to prevent the solder bridge problem altogether.

    If you do not, you may have barebones PCB malfunctioning. Additionally, the solder bridge has the potential to generate short circuits.

    After you have completed the soldering, you must test your barebones boards. Before turning on the board and circuit, you need to test the boards to ensure no problems.

    How Can You Minimize The Time For The Prototype Of Your Barebones PCB?

    PCB prototyping is a time-consuming process in general. According to the experts, the designing procedures and the PCB shipment are the most time-consuming aspects of the process.

    It is generally agreed that you will have to wait many weeks after placing your purchase order for PCBs. In this scenario, the barebones circuit board method may assist you in reducing the amount of time spent prototyping.

    Barebones PCB Prototyping Is A Fast Prototyping Method

    Barebones PCB Prototyping Is A Fast Prototyping Method

    You can expect to get the prototype boards in a week or less because of the fast turnaround time of 24 hours for the barebones PCB. PCBMay may complete the task in the least amount of time by avoiding several customary but ineffective stages.

    • Utilize high-grade materials to make the barebones PCB board. Ensure that the materials are highly compliant with the highest range of temperature.
    • Correctly place the different components. Make sure you keep separating the analog and digital components.
    • Use conformal coating to avoid high heat. It will also protect your board from oxidation.
    • Good surface finishes and epoxy coatings are among the best solutions for high heat.

    What Factors Impact On Barebones PCB Costs?

    The cost of making PCBs is continuously variable. Different entities determine the barebones PCB cost. So you cannot choose a fixed price for your PCB production. Instead, you can predict a costing based on the following entities.

    • The material types impact the PCB production cost. Also, the quantity and quality of the material play a vital role in PCB costing.
    • The components’ quality and types are among the role players of PCB manufacturing cost.
    • The quantity of the barebones PCB impacts the cost. If you produce bulk production, the total cost may be raised. But the rate will be decreased.
    • The PCB thickness also plays a vital role in determining the PCB manufacturing cost. The thicker board you choose, the more it will cost.
    • The size of the PCBs is the most crucial fact that impacts the PCB costing. Different sizes of the PCB vary their production costs.
    • The number of layers increases the total cost. The more layers you employ, the more the price increases.
    • The costs of different types of surface finishes are different because gold is more expensive than nickel and palladium. So, which one you will choose will vary the price.
    • If you make your barebones PCB with more customization and functionalities, you will have to pay more costs.

    What Is The Barebone PCB Surface Finish?

    The surface finishes are the metallic coating to the exposed copper and other metals on the PCBs.  Surface finishes protect the exposed metals from oxidation.

    The Gerber File is the universal design documentation for PCBs. The Gerber File is the standard image input format for bare board fabrication. It is the de-facto standard in the PCB industry. It describes copper layers, solder masks, drill data, legend, etc.

    We will see how you can create a Gerber file for the barebones PCB in Eagle software.

    Begin by launching the Eagle software. Then choose File>> CAM Processor from the menu bar. A pop-up dialog box will appear at this point. Then select File>> Open>> Job from the drop-down menu. Open a design file in a new window at this point.

    You must specify Gerber Files in the newly opened window that has shown. This is required for the component side, the solder side, and the Silkscreen CMP, among other things. In addition, solder stop, mask SOL, border paste CMP, paste SOL, and silkscreen are also available options.

    How do I Use A Barebone Board?

    When utilizing barebones PCBs, you have to put the components together to get the desired functionality. Using the PCB diagram, carefully position each element on the board. Make a list of the features you want to modify.

    Be careful not to position or solder any components incorrectly. You’ll have to redo your PCB if you make a mistake. Time and money will be wasted as a result.

    Now is the time to put and solder the capacitors and resistors that you will be using. When working with the polarity of the capacitors and diodes, you need to do this with utmost care.

    Put the microcontroller into the socket correctly. Solder the programming header and power supply connection jacks into place.

    After placing and soldering all components, check them properly before plug-in. You must connect a USB cable to the microcontroller to get the final product. Make sure you’re capable of doing this.

    It is essential to program your barebones PCB through Arduino or Freeduino. You need to ensure a 100 mils spacing header for your barebones printed circuit board.
