If you are up for selecting the printed boards, some parameters require to be taken into consideration. One of them is choosing the color of the PCB solder mask. Though green is the most traditional color being used, other colors like yellow, white, and black, which are also available, do not require any extra charges. As there is a wide range of colors available for the PCB solder mask, the problem is which color needs to be selected. Are there any advantages or disadvantages to choosing any color other than green?

Given below is the small guide who is going to help you in choosing different solder mask color other than the standard green color: If you are curious about the advantages of purple PCB, please check and read the content below in this passage for more information.

What is the basic information of purple PCB?

The solder mask of the circuit species the color of the circuit. So the purple solder mask will offer the purple PCB. Usually, the general workability increases with purple color but different people have different preferences. And your preference will depend on the purpose you want to achieve from your PCB. As this color is not standard so you may have to place a separate order to your manufacturer to have purple PCB supplied. Manufacturers will charge differently according to your order. So in this sense, you may be asked to pay a premium for purple color PCB.

Why to choose purple PCB?

Even though it is essential to note that there is always a difference between solder masks used in special situations, for instance, in high impedance circuits, specific colors may be chosen to reduce leakage, characterized by impedances. Also, there are cases where colors must be avoided. For instance, there are cases where a transparent PCB is required. In such a case, it may be necessary that you choose one that can serve your needs.

It is also possible to work with a PCB with mixed colors. However, you need to make a particular order from the manufacturer. Such PCBs may be costly and may require that you dig deeper into your pocket. 

The other benefit of using colored PCBs is using solder mask colors such as red and purple to test your PCB’s functionality. Using boards with different colors may be critical if you don’t want to get confused.

Some of the differences between a standard purple PCB and a heavy copper PCB are given below:

·  There is a lesser amount of copper used in standard purple PCBs which is approximately 1 oz having a very thin size. On the other hand, heavy copper PCBs are thick in diameter because there is a large amount of copper in them.

·  By standard, we mean the thickness of the PCB. So the standard thickness offered by manufacturers is 0.063 in or 1.57 mm which is true so far. However, nowadays, there is a range of sizes available depending on your choice for PCB fabrication which is 0.093 in and 0.031 in. while a heavy copper PCB is made with copper ranging from 4 oz per ft2 to 20 oz per ft2.

·  Heavy copper PCBs are designed to deal with heavy activities. On the contrary, standard PCBs can only offer lighter activities.

·  Mechanical strength in heavy copper PCBs is high because of the high use of copper in them; on the other hand, standard PCBs have lesser mechanical strength.

·  Standard PCBs do not offer good conduction for the current. But heavy copper PCBs offer good conduction for the current because of the copper used in them.

·  Thermal distribution is efficient in heavy copper PCBs which improves their performance as compared to standard PCBs.
