Fig. 3 - 22 is a complete electronic circuit diagram made by vertical mounting method. fig. 3 - 22 is a complete circuit layout.As can be seen from the figure, the resistors are installed vertically to save space.Lead the lead at the top of the resistor down the outer wall of the carbonaceous resistor and trim the two leads to the same length.This mounting method is also applicable to electrolytic capacitors with axial leads.Of course, these components can also be installed horizontally.
Dual in-line integrated circuits are usually mounted on circuit boards drilled with a plurality of holes in close proximity to each other.If this type of integrated circuit is suitable for mounting directly on a drilled circuit board, point-by-point wiring may be used, but it is preferable to use an integrated circuit dedicated socket.Care should be taken when inserting dual in-line integrated circuits into special sockets. The pin-type leads of integrated circuits are very thin and will bend or even break if they are not applied properly.The correct insertion method is to align the lead-out wire on one side of the integrated circuit with the hole on the corresponding side of the socket and insert it.Each lead-out is tapered and suddenly becomes square in the middle.When inserting the leads on one side of the integrated circuit into the socket hole, do not insert all the leads into the hole at once.It is necessary to wait until the lead wires on the other side are also aligned with a part of the socket hole before tapping the middle of the integrated circuit element so that each lead wire can enter the socket completely at the same time.When inserting, gently shake the element, which will make it easier to enter the socket.It is very simple to remove the integrated circuit from the socket, as long as a small screwdriver is inserted into one end of the integrated circuit component and the component is gently pried, it can be removed.If possible, you can practice with a bad integrated circuit. If the lead-out of the integrated circuit is damaged, the entire component will be discarded.
3 - 10 Summary
To successfully manufacture electronic circuits, a good start must be made, and correct manufacturing techniques must be adhered to and excellent components must be adopted.Assembly of electronic circuits is not too complicated, but all components and tools must be ready before production can begin.If there is a lack of components or poor tools in production, a lot of time, money and setbacks will be wasted and nothing will be achieved in the end.
Don't force yourself, this is a basic rule.Don't set yourself a deadline when making circuits.Because this will make you irritable, especially at the beginning of the production, the progress is very slow.Whether it is experienced or inexperienced producers, mistakes will be made when they are impatient.When an error occurs, the components will be damaged or the circuit will not work, sometimes even the entire circuit will be scrapped.Making it in a normal order and in a reasonable way will help you learn more about the manufacturing process, the performance of the components and the function of the circuit.In this way, even if the electronic circuit is first made, there will be a 100 % chance of success.
In this chapter, only some simple circuits are mentioned. Readers should develop good manufacturing habits when making simple circuits.If you don't pay attention to this learning process, you will eventually fail.So when making electronic circuits, be sure to follow the requirements. It will make you succeed.
