PCB Design Steps

hMost of the professionals working in the engineering industry, deal with the electronic circuits. They use the Printed Circuit Boards to manufacture these circuits. The boards comprise some special and unique materials (glass and fiber), which are not capable of conducting the electricity. In PCB manufacturing, copper tracks are used with the boards for designing the circuits. They do not choose the wires to transfer electricity to the electronic parts.

PCB design- Know all the steps clearly to accomplish your task

The position of electronic parts is stable, and the manufacturers drill holes on their board. They also place the elements and solder them rightly. The right positioning of all the components, including the circuit board, helps in the development of circuit. These PCBs are useful for various electronic items, like wireless tools. They offer the fastest functioning, better control and accurate results. You may not get these advantages from the other wiring processes.

Now, we will talk about the major PCB design steps.

Find out the best software for designing PCB

For drawing the circuit diagram, you have to use the best PCB board design tool. The online sites present you with different tools, helping you to deal with the design. In most of these pcb design software applications, you can find various components. All these components are useful for the development of a circuit. You will easily be able to alter the position of a circuit design. Then, you may also modify it for your own requirements.

Some PCB design applications are downloadable, while others work on the digital platform without any download option.  You have to open the interface of your chosen software. You can press the file and library menu for dragging the fresh design.

The best pcb design software helps you not only to create PCB but also to simulate the circuit in the browser. You have to check out the compatible components. The Cloud-based software has features to enable you in browsing designs. Make sure that the software runs properly in the Operating System of your device.

Using your PCB layout application, you may have created a diagram of circuit board. You can create a film from it and send it to a manufacturing unit for the printout of the mask on a sheet.

Choice of the raw materials

In most cases, the fiberglass or unbreakable glass is useful for most of the PCBs. The copper foil has to remain attached to the board’s one or both the sides. The PCBs, made of copper foil and paper phenolic, are available at a lower price. They are also useful in various electronic units of our household. The thickness of the copper clad has to be of the industry standard. You can cut the panels to various sizes.

Preparation of the holes

The carbide drills and special machines are useful for putting holes on your PCB. For this drilling process, you can find machines of two different types- CNS and manual machines. With these manual units, you have to apply your own effort for drilling holes.

CNC units are based on the computer systems. The integrated programs or timetables run manually and automatically. The computerized system stores the pattern of drill. For instance, it can store the size of drill bit, time for drilling and the number of drilled holes in every panel. After placing the boards on your machine, you can drill the holes, based on the set pattern. Thus, these are all about the drilling process to develop PCB.

Application of the image

There are various ways of having the printout of your printed circuit layout on PCBs. You may use printer, pen plotter, dry transfer or manual pen. Laser printers offer you the best option for printing layouts on any PCB. You have to follow a few steps for the printout of PCB layout. These steps are applicable for a laser printer user.

  • Place a very clean copper paper on your printer
  • Then, use the computer system for storing the layout film that you have designed.
  • Use the print command, and the printer helps in printing the circuit layout. You can have it on your copper paper.

Start the stripping process

A part of the copper element remains unwired on your PCB. At this step, you have to remove this copper with the use of various chemicals, including ammonium per-sulphate, and ferric chloride. You have to prepare a solvent with the blend of some ingredients- water (1 percent) and sodium hydroxide (1 percent). You must also use the pellets of this hydroxide (10 grams).

Make sure that all the ingredients of your solution are dissolved fully. Then, you can put your PCB into your chemical bowl. Use a brush for cleaning it up. This cleaning process is essential while your PCB has a greasy layer for you have applied seed or sunflower oil. The overall process of development covers one minute.

It’s the time to test the product

You have already gone through the major steps for manufacturing Printed Circuit Board. Start the process of testing the board. This process helps you to make sure that your PCB will perform the function smoothly. Nowadays, you may find several tools for the automatic testing of the PCB. They help you with a high-volume PCB testing.

The most common testing tools, available in the market, are ATG machines (like fixtureless testers or flying probe). The universal grid testing is also applicable for the analysis of a circuit board. Choose any of these tools for creating your PCB board.

Thus, we have presented a comprehensive PCB design course. You can follow the above steps to design any PCB rightly. We think that this tutorial will help you to have the major idea on the topic. However, you must have some technical skills to learn the process clearly. There are several companies, offering their PCB design service. However, while you like to create the board with your own effort, you can take part in a training course. The assistance from the trainers will make your task easier.
