Everything you want to know about printed circuit board designing and artwork

An introduction to the design of pcb manufacturing china

The design of a printed circuit is generally required when you want to connect electronic components together. In this way, pcb manufacturing china are able to produce a complex electronic circuit.

The printed circuit is present in almost all electronic devices. And it is quite easy to design it provided you have the required knowledge. Do you want to try your very first PCB design? Excellent idea!

But first, make sure you have enough information to adopt the right approach. Already,

• What exactly is a printed circuit?
• And what is it used for?
• What does it take to make it?
• What are the different stages of designing a printed circuit?

And finally, what are the rules to follow to place its components correctly? Find answers to all of these questions in this article.

The printed circuit is also designated by the initials pcb manufacturing china. It is a support which generally takes the form of a plate. And it ensures the electronic link between separate electronic components. Thus, we use PCB to make an electronic complex.

How pcb manufacturing china takes up the layer of pcb?

pcb manufacturing china makes pcb boards using several very thin layers. These are made of copper. And they are separated from each other using an insulating material.

In order to obtain several tracks, the copper layers are etched using a chemical process. The operation is completed thanks to the use of tablets. And to protect the tracks from oxidation as well as short circuits.

Note that the tracks mentioned here by pcb manufacturing china constitute the elements. As for the pellets, they make it possible to electronically link either the copper layers or the various components.

What is the purpose of an electronic card?

The uses of printed circuits are many and varied. It is mainly used to weld components. And printed circuits are present in almost all the devices we use today. They are found for example in:

• radios;
• remote controls for television sets
• household appliances;
• microcomputers;
• or the cards accompanying the arcade games.

You should know that some components of computers are, by design, printed circuits. These include memory modules, motherboards as well as expansion cards.

What are the elements necessary for pcb manufacturing china?

It is the epoxy resin which allows the design of a PCP. Then pcb manufacturing china doubles it by a very thin layer of copper. Also, the copper layer of the PCP allows the design of electrical circuits.

The electrical components are implanted by soldering after the through holes have been drilled. Among the implantable electrical components are:

• integrated circuits;
• capacitors;
• the diodes;
• resistances; and,

It will be possible for pcb manufacturing china to connect these components. The plate thus obtained will then be an electronic subsystem.

How does pcb manufacturing china design complex pcb?

The design of more and more complex circuits makes it possible to note a great evolution. Thus, the layers of the circuits become more and more numerous.

We will find for example at least six layers in the motherboard of a microcomputer among which we have:

• a layer intended for the mass;
• and a layer intended for the 5 V supply.

It is also possible to find PCPs made up of around thirty layers. This is noted in the case of circuits of extreme complexity.

What are the different stages of designing a printed circuit?

The circuit board design obeys thirteen precise steps which are:

• the choice of pcb manufacturing chinafor manufacturing a printed circuit;
• the creation of the artwork;
• adjusting the dimensions of the PCP;
• printing of the electronic card;
• the installation of the artwork;
• start of the circuit transfer;
• the continuation of the transfer operation;
• preparing the cooling of the electronic card;
• cooling of the electronic card;
• removal of the artwork;
• drying of the electronic card;
• engraving ;
• The finishing of the card.

Choosing a technique for pcb manufacturing china an electronic card 

The design of a printed circuit begins with the choice of its creation method. Obviously, you must make your decision taking into account the materials required by the process.

But pcb manufacturing china must also take into account the technical difficulties. Finally, you must also have a precise idea of ​​the quality of the PCP that you wish to obtain.

THERE ARE FOUR METHODS FOR MANUFACTURING A PRINTED CIRCUIT:

1. NAMELY CHEMICAL ETCHING
2. ULTRAVIOLET RAY ETCHING
3. MECHANICAL ETCHING AND
4. LASER ETCHING.

The etching takes time and requires strict security measures. In addition, you must have certain specific materials such as the attack reagent.

Chemical engraving is a technique that is well suited to the design of simple. It is however not recommended for the design of printed circuits with close connections.

The burning ultraviolet demand fairly expensive materials. On the other hand, its implementation is simple. And it guarantees obtaining circuits that are both fine and complex.

The mechanical engraving is also called “routing.” It requires the use of special machines to remove excess copper from the card. Mechanical engraving will be expensive for PCB manufacturing china unless it doesn’t have to buy an engraving machine.

The best would definitely be to rent one. Aside from this drawback, mechanical etching is ideal for manufacturing a printed circuit in several copies. Likewise, it ensures obtaining good quality electronic cards.

Finally, laser engraving is the one that is most often used by large production companies as well as universities. The principle of laser engraving is very similar to that of mechanical engraving.

The difference is that it is a laser beam that does the work here. Such machines are difficult to find.

pcb manufacturing china creation of the artwork

The creation of the artwork consists of tracing the tracks of the circuit. If pcb manufacturing china etches with an acid, use a material that is resistant to it.

The second method is very attractive. It is not suitable for medium or complex circuits. And you usually need special software to convert the circuit diagram. You have the choice between several free software.

Adjusting the dimensions of the PCP

The third step for pcb manufacturing china is to adjust its dimensions. You must first complete it on your computer. Make sure in the adjustment that the dimensions match those of the paper.

Printing the electronic card

You then go on to print the PCP again using the software. Use glossy paper for printing and make sure it is mirrored. Above all, do not touch the ink of the artwork after printing. Otherwise, you risk erasing it.

The laying of the artwork

Now pcb manufacturing china need to put the front of the artwork on the copper side of the card. Make sure there is an alignment between the two parts. Then, turn on your electric iron and position it on its support.

The start of the circuit transfer

The next step in PCB design is to start the circuit transfer. It will therefore be necessary to place your well heated iron on the artwork.

Preparing the cooling of the electronic card

pcb manufacturing china should now be ready to cool the card . For this, you must first carefully put the iron aside. Then take the card and go to the tap closest to you.

Warning! The hot paper will always be pressed against the card and should not be removed at this time.

How does PCB manufacturing china Cool the PCB board?

Once you reach and open the tap, position the card under the stream of water. You can still, if you prefer, immerse the plate in a container with hot water. But, do not go beyond 10 minutes.

The electronic card is a circuit formed of components integrated into a mechanical structure. It is present in almost all commonly used electronic devices. And the circuit board design is done by following well-defined steps.

Likewise, this requires professional pcb manufacturing china services. Mastering and applying precise rules. Particularly when assembling the various components.
