 Second Day, Week 4 

TUESDAY,17 July 2012  

 My second trial was the second day of the week 4.As usually, i'm continue to run and often asked Mr. Mazran want we can not do. The route on the board must follow the required size. At the same time, we must know which components in SMD or through hole.

For this entry, i will explain to you about the PCB LAYOUT DESIGN. Before we start go next step, firstly is, check rule. It is best practice for us to check rule for your Conduct electrical circuit. ISIS can check for simple errors in a design byexamining the u pin types connected to each net. you can do it by go to Tools> Electrical Rule Check . Confirm that no error in your circuit design through the report generated.

“Netlist” is another important feature in electrical circuitschematic. “Netlist”  will show what connect with what in electrical connection. Furthermore, information in netlist will be utilized when we convert our schematic to PCB layout. “Netlist” can be compiled from Tools > Netlist Compiler

Foot print refer to PCB layout of our individual component.As mention earlier, several component here don`t have any footprint (e.g. LED, battery). Check whether the component have footprint or not by selecting the component and right click it and go to Packaging Tool.
