A PCB or Printed Circuit Board is one of the essential parts of an electronic device as all the electronic components are mounted on a PCB connected with the tracks printed on it. We can also consider it as the foundation for a successful electronic device as every operation of the device depends on how perfect the PCB is. While the process of PCB designing is essential, the validation and manufacturing phase holds an equally crucial role to avoid common PCB design mistakes.
Here is a quick brief about PCB Validation and Manufacturing, which can help you out in the smooth process of manufacturing a perfect PCB.
What is a PCB?
While designing and building an electronic device, all the electronic components need to be connected both electrically and mechanically. A Printed circuit board (PCB) has printed electrical tracks, paths, and footprints of components etched from material like copper. The PCB paths and trails are conductive so that all the electrical components can be connected to fulfil the desired functionalities. The electronic components, namely resistors, capacitors, and other components, are soldered according to the PCB design. The components are embedded in the PCB as a complete circuit and then integrated into the device.
The main elements of the PCB are dielectric substrate (rigid or flexible) with copper conductors on it, vias and holes both plated and non plated. PCB Design can be single layered or multi- layered according to the complexity of the circuit and form factor of the final device. The PCB board also consists of an insulating substrate, i.e. mostly FR-4 epoxy and can be other materials as per the design needs.
PCB designing is the process of designing the circuitry using potential PCB Design software such as Altium, Eagle, Ki-Cad, Easyeda etc, consisting of diverse essential PCB tools helping us to make a perfect design, and also runs a DFM (Design for Manufacturability) check so that no problem is faced during manufacturing. A perfect PCB is designed, keeping in mind the complete requirements of the device. The design is tested as per the requirements with the help of simulations. Let’s understand the process in detail.
Testing and Validation: Testing the prototype and validating it with the software
After the PCB design is complete, the next step is to manufacture a prototype and to test it under various conditions and constraints to assure the quality and robustness of the hardware. The prototype and its application or dashboard need to be validated before taking it forward for manufacturing processes. The different parameters of the hardware such as signals, voltages, amplitude, magnitude, temperatures, heat conditions, power consumption etc. are tested. The prototype is created several times till the final prototype is ready covering all the requirements of the client. The final prototype is the one that fits the client’s requirements thoroughly, and the client approves it for manufacturing. At the end of this stage, the delivery of the prototypes, design files, test reports, estimates, and a detailed set of future recommendations is done.
Manufacturing: Fabrication of the Printed Circuit Board and its Assembly
The manufacturing of the product can be done for bulk products. Test such as stress testing, defects identification, and individual components testing is performed for the product after the first batch manufacturing, for quality check and to reduce rejection. After the issues are identified, the reason for the problem is checked, and the rectification of the problem is started.
Maintenance: Product lifetime support.
After all the stages, as mentioned above, get completed, the product is marked complete. Now the maintenance part starts. The product needs modifications from time to time to remain up to date with the technologies. The engineers and programmers provide maintenance throughout the product’s lifetime. The firmware updates are provided, and new features are updated every now and then.
This is the last stage of the IoT Product lifecycle.
The process of PCB validation and manufacturing is not only vast but also fundamental when making an electronic device. The process is crucial as the slightest mistake can lead to the failure of the product.
