The progression of our project by this week is,we have completed design the PCB by using software which is DIPTRACE. Using this software can reduce our IC and jumper ,instead of that,we can create and design circuit which is can make a size of original circuit to become small circuit than before. Diptrace is for creating schematic diagrams and printed circuit boards.
Using A Diptrace,the first thing we need to do is construct the schematic diagram and PCB Layout.To construct schematic diagram we need to use schematic diagram to make sure the connection is correct. After done the schematic diagram, then we may convert the circuit into PCB by Diptrace software. By using the multisim for the first step is to make sure our connection is correct before we transfer to PCB by Diptrace software and troubleshoot it when it have an error an connection.
Below show of our pcb layout:
Both picture above show the connection of circuit which is view form top and bottom.By looking view from the bottom show the copper connection and components hole to solder.While view from the top layout shows the components symbols and positions.From that state,it will make our work easily to solder at PCB board.
After we design the PCB using Diptrace,then printed circuit on the paper of Transparency using a special printer.Next we need to go to Lab, we have to bring our printed circuit and PCB board.
One of technique that we want to produce our pcb circuit is by using Ultra Violet transfer.UV rays produced by UV Exposure tool that will transfer print circuits on a transparency layer to Presensitized PCB.
Presensitized PCB equipped with light protective layer. This protector should be opened before doing this process.Layer Transparency should be inserted above the light sensitive PCB Presensitized using transparent adhesive tape. The most important is ensure transparency layer attached position not reversed because this process using UV Acting Positive Transfer.
Before that we have to cut our pcb board according to Transparency paper above circuit size.
After done all the technique,we have to do etching
Below show the etching manually other using machine.
Finally,wash the circuit with water,make sure all the line of connection clear if not use a permanent marker.
Next, we directly do drilling process to punch holes in the PCB to place components on the circuit legs.
The size of the hole depends on the type of components used. Use the correct size drill bit depending on the size of the component legs.Please make sure do step by step and observe safety precautions when using this equipment.
Next entry will show the progression ,we will construct component and soldering to the pcb board.
