The performance of any electronic device depends on the PCB. In fact,PCB trace is an essential part for each PCB just like a current. Moreover,if engineers have used a wrong calculation in fitting the trace,it will obviously take much energy and time to correct it.So,if electronic engineers use wrong trace in their PCBs,their products will perform poorly.
In modern technology,PCBs are the basic element in almost all areas.And everything around you totally depends on PCBs. Whether they are smartphones or 3D printers, electronic industry totally relies on these PCBs.
Furthermore, popularity of Printed Circuit Boards is rapidly increasing day by day in our daily life.And electronic engineers are preferring copper in fabricating these PCBs. In fact, copper, is an ideal choice to create PCB trace. Here we will discuss that why electronic engineers are mostly using copper for a successful PCB industry.
What is PCB Trace?
As we have already descried that PCB trace is part and parcel for every PCB.When we talk about PCB,trace involves the network of
- And even insulation which fabricates a printed circuit board.
Hence, the perfection of PCBs totally depends on trace. Whenever, you find any type of inconsistency in your electronic device. Then it is clear that there is a serious fault in the trace.
Moreover, it is a fact that performance of electronic appliances totally depends on the correction of trace. The most regular term which electronic engineers use in the industry of PCB,is trace resistance.Basically, the meaning of PCB trace resistance is parts of a PCB which resist the electric flow.
Furthermore,there are several different components in PCB.But it is really important for you to know that which materials and parts you need to assemble or repair the PCB.
These PCBs help to save lots of spaces and also reduce the overall weight of the board. Furthermore,there are many kinds of PCBs but flexible PCBs are ideal for countless applications,because in several applications electronic designers need high signal trace density.
The Thickness of PCB Trace
In any PCB design, the PCB thickness always plays an essential role for all electronic devices. Because the thickness of PCB has ability to maintain balance. But there is no danger for PCB damaging. Moreover, thickness also involves all the components which engineers connect to the circuit board.
Width Calculator of PCB Trace
It is a real fact that in PCB design, width of PCB trace is very important design parameter. Moreover, this is very essential for the designers to do an appropriate trace width. Hence, in this way they can be sure that this trace has ability to transfer the perfect amount of current. But without damaging and overheating the board.
In fact, the higher amount of current requires the thicker traces. On the other hand, the thicker weight of copper also permits for thinner traces.
Furthermore, here is the formula for the resistance of a trace:
- Resistance = Resistivity*Length/Area*(1 + (Temp Co*(Temp – 25)) and Area = Thickness*Width
- A copper Thickness of 1 oz/ft^2 = 0.0035 cm
- Copper Temp Co = 3.9E-3 ohm/ohm/C
- Copper Resistivity = 1.7E-6 ohm-cm
- Power Loss is Current^2 * Resistance
- Voltage Drop is Current * Resistance
Additionally, here is something most important for you to understand before measuring the PCB trace width. In fact, it is very complicated to calculate the trace width in comparison to any conductor. Moreover, there are several facts which you must consider before calculating the width of the trace of any PCB.
First thing that you have to know is, maximum electricity which basically has ability to perform the functions of the board as input. Furthermore, it includes,
- The unit of the measurement trace
- Temperature of the trace
- Thickness of the trace
- And trace ambient temperature.
It has ability to make a deep effect on the width input ranges.
As you plug in the numbers into the calculator, you will obtain the output figures.
You will also obtain figures of the width of PCB trace including
- The trace width (measured in amps)
- The trace temperature (measured in Celsius)
- Resistance (measured in ohms)
- The power dissipation (measured in watts)
- The voltage drop (measured in volts).
Hence, all the above information will help you to understand clearly that what the actual width of trace is.
Five Benefits of Using Copper to Create PCB Trace
As we know that PCBs are the basics of electronic devices. Moreover, the performance of your products totally relies on these PCBs. There are several materials which manufacturers use to fabricate PCBs.
Nowadays, electronic engineers are rapidly using copper in order to create their PCBs. Here are some benefits which copper has in comparison to other materials. These are:
The first and most beneficial advantage of copper is,
- It is highly conductive
Because it has capability of easily transmit of the signals.
- It does not lose electricity or current in the way
- Designers need only a small amount of copper for perfect manufacturing of PCBs
- There is no need to use tons of copper
- Copper is relatively low cost and easily available.
So electronic designers prefer copper to create PCB trace.
In fact, an ounce of copper has ability to create 35 micrometers about 1.4 thousandths of an inch thick. And these micrometers have ability to cover all square foot of the PCB substrate.
Copper is highly conductive because it possesses only one valence electron. These kinds of electrons have ability to travel freely from one atom to the other. But with very little or less resistance.
Hence all the above factors have made copper an ideal choice to create PCB trace. Because copper has many advantages in comparison to other metals for entire fabrication of PCBs. Furthermore, it is low cost and you can get it easily for your perfect trace of PCB.
