Electronics design can be complicated and designers usually face the issue of wasted resources and rework. This is because of the use of small tracks for circuit layout since not all components could not fit. One more reason is the rush to meet the deadlines.
Communicating with the manufacturer is also very important. If something is not clear or the designer failed to share all design schematics and components with clarity, the manufactured product can be expected to be flawed. Technical challenges also come with these things.
Pre and post design analyses are highly important in order to ensure proper electronics design and circuit outcome. These includes the following considerations.
Right Board Spacing
Choosing the right spacing will save you a lot of money and rework. It is very important to make sure that you have the right digital representation of the circuit before proceeding to the production. At the same time, you need to define all components and circuit schematic during the design. If you happen to miss out a component, you have to define it in the CAD library in the proper way and process all information.
Protection Against ESD
ESD or electrostatic discharge is caused by sudden electrical energy. This is developed by electrostatic induction or static electricity which flows from one charged object to the next. The components of the electric circuit are very sensitive to ESD. This is why design and manufacturing floor areas need to invest in ESD-protected areas where highly charged objects are kept out.
Save your Circuit from EMI
EMC or electromagnetic compatibility is important in ensuring the quality of the circuit that is being designed. This also helps ensure that the electric circuits are not disturbed by EMI or electromagnetic interference.
One reason for EMI to rise is due to radio-emission of another electronic object. This affects the electric circuit by providing it with wrong data or by making the system stop. You can perform EMI shielding by using components such as capacitor filters and ferrite beads.
There will always be a time when two charged ends of an electronic device are connected to wrong terminals. One best example is attaching a battery in a reverse polarity to an electronic device. If the design of the circuit is not properly protected against reverse popularity, you can expect some hazardous outcomes such as frying or malfunctioning of the circuit. As a precautionary measure, you can connect the heavy load that carried the microprocessor output drivers to a large resistor. You can also use a diode bridge to rectify the input and ensure that there is correct polarity in the circuit.
These rules will serve as your guide as accomplish your design. Having them in mind will spare you the trouble of making mistakes that may or may not be easy to fix.
