:: Have a look of this board and compare it both..
The picture that you see above is the picture of two UV board which is one of it was wrong UV board. You can see the different right? It look like almost same but it actually not. The one at the right is the one that wrong UV board and the one at the left is the correct one. You can see the different by the colour for sure,which is the board at the right is look like shinny gold but the another one is more to light yellow. Here,have a see it more clearly close..
The one is wrong UV board |
This one is the correct UV board |
After i see both of this UV board,then now i know what is the different and why we cannot simply use any board to do PCB fabrication. First thing that we need to do when we want to buy the board is we need to make sure that we bought the correct one. If you not sure about how the board look like,you better bring along the sample of the board then show it to the seller. At least you will not buy wrong board as what we do. So the moral of the story,make sure you know how the things look like when you want to buy something. If not,you better bring the sample in case if the seller also did not know the things that you are looking for. It is better if we be well-prepare or if not we will going to wasting our own money to buy the wrong things.
P/S: This UV board is use to do PCB Fabrication for last assignment in Engineering Design subject
