PCB DESIGN, ETCHING AND DRILL

Assalammualaikum..

The next step for our project, we construct our circuit PCB design by using Diptrace software. After that, we done our etching and drill the PCB board at level 1, UniKL BMI.


PCB Design

Figure 1.0 Circuit diagram

We are using Diptrace software to make the circuit compact. After we done the simulation, the next step is as follow.

Etching

Figure 1.1 PCB board 

The etching process involves sheets of metal, usually made of copper or zinc, and acid used to etch the print onto the metal.  The more complicated the etching, the more time consuming and expensive it will be. We are using the following board to etching the circuit. Below are the steps that we done before we go to the next steps.

Drill

Figure 1.2 Drill box and tools

A drill is a tool fitted with a cutting tool attachment or driving tool attachment, usually a drill bit or driver bit, used for drilling holes in various materials or fastening various materials together with the use of fasteners. The attachment is gripped by a chuck at one end of the drill and rotated while pressed against the target material. The tip, and sometimes edges, of the cutting tool does the work of cutting into the target material. This may be slicing off thin shavings (twist drills or auger bits), grinding off small particles (oil drilling), crushing and removing pieces of the workpiece (SDS masonry drill),countersinking, counterboring, or other operations.
