A Method for Creating PCBs

Dated:2017-11-09      Popularity:1105


Your choice for creating PCBs is usually based on the availability of the materials needed for the method, the technical difficulty level of the method, or the PCB quality you want to achieve. Here's a brief description of different methods and their main features for your reference.

Acid Etching: This method requires extreme safety precautions, the availability of many materials like etchant, and it is somewhat slow. The quality of the PCB obtained depends on the material you use, but in general this is a good way to get simple or medium complexity circuit boards. Circuits involving more close wiring or tiny wires often use other methods.

Laser Etching: This is usually used by large manufacturing companies, but still can be found at some universities. This concept is similar to mechanical etching, but the laser beam is used to etch the circuit board. It is often hard to get such a machine, but if your local college has such a machine, you can use their facilities if they allow.

Mechanical Etching/Routing: This method requires special machine which can mechanically remove unwanted copper from the circuit board or route empty separators between wires. It can be expensive to buy such a machine, however, this method is useful if you need to create multiple circuit copies and fabricate qualified PCB boards.

UV Etching: This method is used to convert PCB layouts to PCB boards and requires more expensive materials that might not be available everywhere. However, these steps are relatively simple and can produce finer and more complex circuit layouts.
