How to install electronic components? Answered

Hello. everybody.

I'm new to this electronic hobby thing. I'm trying to make a simple sound amplifier, purchased all components, have the schematic of the circuit BUT I have no idea how to install them on a protoboard (breadboard).

I've one of these: http://img.td-imgs.com/images/67/14/26714_971289_CTL-26714.jpg

I don't know how to use these boards. Are those circles painted with copper? How do I turn this into a circuit board?
 Eventually I lost my mind and started wiring up the components but it's really messy and time consuming.

I couldn't get a mainstream breadboard so I picked the one above, but it seems to me that it's just a support for the component and the wiring part is still inevitable. I can't find tutorials on this topic, heck I don't even know how to search this topic. It's very annoying.

Please give me some feedback. Thank you.

Very often, I just use a BLANK (un-etched) pc board that has a layer of copper on both sides. I just use the whole surface of the board as a grounding spot. I just glue all the components down in a general location that sort of lines up with how the schematic is laid out. Then when the glue dries, just run all the jumper wires using some thin wire about 26 to 30 gauge thickness. Sometimes, I may use a dremel tool to cut squares into the copper layer. Use those squares for things like PLUS input or input/output signal pads to solder to. This method works great for prototyping or just building something quickly but not for making a production-run of several circuits. You could also use the method of hammering nails into a piece of wood and use them as contact points. But only if the circuit is low frequency and low voltage. Wood can conduct electricity and mess with your project becoming a failure using this method.

Solder and soldering iron. Watch some soldering videos on Youtube.

I have a TDA7294 IC with 15 legs, each at a 2 mm distance from its neighbor. How am I supposed to connect those legs to the other components without using a printed circuit board? All I have is a perfboard..

Use the long legs from adjacent components to reach over to the chip. You just have to create solder bridges across to each component. This instructable should help. You can use leftover legs from components or wires to help create your trace. It's all about having all the parts laid out and well organised on the board.
