Simplifying The Printed Circuit Board Design Process - Miracle Electronics
Designing Printed Circuit Boards is a challenging task that requires complete understanding of more than just circuit functionality, such as how the board will fit within the application, how heat will be dispersed within the board, and much more. With all of this to be considered, designing a Printed Circuit Board can become really complicated, which is why you’ll need to get your circuit boards from a professional Printed Circuit Board manufacturer in India, who has complete knowledge and understanding of every aspect of the PCB as well as its designing procedure.
One such manufacturer is Miracle Electronics, who has been manufacturing a wide range of PCBs and supplying them successfully to clients across the globe since more than a decade now. However, this blog also lets you know a few tips to simplify the PCB design process, bringing ease to the oh-so-very complicated process.
Spacing between components
One may want to stuff as many components onto the board as possible. However, there must be ample space left between the components. Putting up components too close to one another can create a number of problems. Also, cramping up the components together may leave very little room for wiring; thus creating additional problems. Thus, there must always be enough space left between components to avoid any such problems, while also making it simpler to solder the components in place, and making auto-routing easier.
Orientation of components
The components must be placed within the same orientation. Keeping a single orientation throughout the entire circuit board can lead to fewer errors during the soldering process, while also making inspecting the circuit boards simpler.
A small loop size
Keeping the loops small in size ensures avoiding certain issues. Smaller loops themselves possess lower inductance; however, keeping the loops over a ground plane can reduce inductance even more. Smaller loops also reduce high frequency voltage spikes and the number of signals in the node.
Appropriate trace size
Copper plays an important role in a circuit board design; and equally important is the amount of resistance within the copper wires. It is thus important to size the traces appropriately to account for things like voltage drop, power dissipation, and temperature increase. And for this, the length, width, and thickness must be factored in to control resistance. Because the physical properties of the metal cannot be controlled, the size of the metal can be decided upon to combat resistance and other challenged that can affect the performance of the circuit board.
Correct placing of decoupling capacitors
Decoupling capacitors play a significant role in a circuit board design, but only if they are placed appropriately. They must be placed as close as possible to the power and ground pins of the integrated circuits to improve their efficiency and reduce inductance.
Avoiding 90 degree trace angles
Creating a 90 degree trace angle can prove to be problematic; for example, the outside corner becomes narrower than the standard trace width, or multiple angles can only be partially traced, leading to shorting and other problems. Thus, instead of 90 degree angles, 45 degree angles must be chosen, to ensure that etching can be fully accomplished, while avoiding shorting.
