Technology in PCB Designing

Greetings and welcome to today’s lecture. It is going to be a very interesting and interactive class about introduction to Through Hole Technology (THT) and Surface Mount Technology (SMT) that are applied in the process of designing the printed circuit boards.  A PCB board is made up of properly designed circuits that are composed of connecting wires/paths and various electrical components. The electrical components are mounted on the board. In fact, they are fixed to the board. If the components are not fixed, then there will be no durability and this might lead to various losses that can be avoided. In the process of mounting these components, here is where the through-hole technology and the surface mount technology come in.  They are very important processes in the design of printed circuit boards.

Overview.

This is one of the methods used in the attachment of components to PCB during the manufacturing process.

  • THT is the oldest among these PCB attachment methods.
  • For so long time it was the standard method that was used in the PCB assembly process.
  • In the 1980s, when the surface mount technology process was introduced in the field of the PCB assembly, so many people thought that the THT method will become extinct but that is not the case.
  • THT is used in all kinds of PCB designs i.e. Single Layer PCB, Multilayer PCB, Flexible PCB etc.

Through-Hole Technology (THT) is the method used in the attachment of the PCB electrical components and elements in the PCB whereby the components being placed have long leads that are soldered into the board through the holes drilled.

Process

  • Dill holes on the PCB following the clients’ design.
  • Select your components. They must have long leads. Also, remember components are on the design you have been given by the client.
  • Place the components on the board and ensure that their leads are on the holes as defined in the design.
  • Check that the components are in the positions described in the design to ensure that there will be no errors at the end of the process.
  • Solder the terminals on the board accordingly. Ensure that the solder is on one side of the leads.
  • Fill the other unsoldered side with flax.

Initially, this process was done manually hence it took a lot of time before coming up with a single complete board. Today, due to the changes in technology, it has become so easy to carry out the through-hole technology process. There are several automatic systems that aid out in the process and make it easy for the manufacturers, for example, the introduction of the automated insertion machines which actually helps in inserting the electrical elements into the drilled holes in the PCB before the soldering process starts.

Classifications of Through Hole Components.

We have talked about the electrical components being placed on the PCB boards through the through-hole. These components can be classified into two that is the radial leads components and the axial lead components.

The radial leads components.

From the image displayed, there is already something that is building up in your mind. Observe it well. Look at the leads. Can you see something common with the device leads? Yes of course. You are right! Both the two leads originate from the common side of the components. That is what we call a radial lead component. This method finds its application commonly in the packaging of the capacitors.

The components can be mounted either vertically or horizontally.

Let us have a look at that from the images below.

The vertical mounting of the Radial THT components.

on this method, the component is always place perpendicular to the board while the base is placed parallel to the board. complete joint. Soldering is done on one side of the terminal and the other side is filled with flax.

The horizontal mounting of the Radial THT components.

the contact body is fixed on the horizontal as you can see from the images. The leads exhibit a very nice bend and also spacing. This allows the proper filling of the solder on the component hence forming the strongest

The Axial leads Components.

  • These are the most commonly used elements of the THT PCB methods components assembly.
  • Here the leads of the components appear from opposite sides to each other. See what is in the attached image on the left.

Also, it can be classified as horizontal mounting and vertical mounting.

Applications of the THT

  • High voltage areas eg in the medical equipment.
  • High mechanical stress devices eg military equipment.
  • High power areas eg in the steam boilers.
  • High temperatures operating devices eg in the nuclear plants.
  • Prototyping and testing of components.

 Advantages of using the THT method of PCB components Mounting.

  1. The use of the THT method will ensure that you have a very strong mechanical bond compared to the SMTs components.
  2. THT bound components have high resistance to wear and tear and this is made possible by the use of the large soldering deposits at the terminals.
  3. The THT components are very easy to swap and repair the components hence they are the best for prototyping works.
  4. It is best suited for places where strong mechanical applications are needed such as aerospace and military equipment.

 Disadvantages of the THT method of PCB components Mounting.

  1. Due to the drilling of the required holes, the production cost goes higher compared to the other method.
  2. Also, drilling of the holes requires some additional time, hence the THT method takes a longer time compared to other methods.
  3. This method limits the available routing paths for the multilayer PCBs because the drilled holes have to go through the given layers.
  4. The technology being used in the industrial mass production of the THT types of the PCB is less reliable compared to the other methods used.

The Difference Between THT and The SMT in PCB.

THROUGH HOLESURFACE MOUNT
The components require the drilling of the holes for mounting.No holes are required for mounting. Mounting is done through pads.
All the components are mounted on one side of the board and it is in most cases done manually.Components can be mounted on either side of the board and the process is mostly automated.
The process of mounting is either manual or can be automated.The mounting process is basically automated.
Do not employ the use of stencils.This process involves the use of stencils to be achieved.
There are no vias in the pads.Use of the vias in the pads.
These are used when a low density of the component is needed.This works so well when the component density is very high.
Reworking and repairing are very simple.Here the process of repairing and reworking is very complex.

Hiring for the IT Department

Finding the right IT professional can be a challenge. Companies want someone qualified and experienced. They need to ensure recruits get along well with the team and fit into the company culture. IT Recruitment Agencies in Sydney offer such services at affordable rates. Statistics suggest that over 2.4% of the population in Sydney works in the IT sector. Agencies also ensure certain features that are essential for every IT worker today. Thus, this article will shed light on some such factors. It will further enunciate the benefits of these techniques.

Ensure the candidate has worked in an agile environment.

Agile software development methodology focuses on solving business problems in short cycles or sprints. It’s an iterative approach to problem-solving and building software, intending to get valuable features out as fast as possible.

While some think that agile applies to software development teams, it applies to any work involving iteration and rapid change. This activity can include software engineering tasks like bug fixes and product updates (usually done by developers). Still, it also includes more general duties such as marketing campaigns, sales orders, and even project management efforts—all things that have been proven successful when implemented using agile principles.

Check their technical knowledge.

If the candidate has had experience in the field, you should ask them about specific technical concepts. A question like, “Explain TCP/IP to me” or “Tell me how a database works” would be appropriate.

In addition, try asking them about their experience with specific technologies and programming languages. For example:

  • What operating systems do they use?
  • Do they have any experience with [IT tools]? Have they programmed in [programming language]? Most people are familiar with Microsoft Office products but if one’s company uses something different (like Google Docs), make sure they know how it works.

As iterated earlier, Statistics suggest that over 2.4% of the population in Sydney works in IT. This fact sheds light on the diverse qualifications of these professionals.

Problem Solvers?

Companies in Sydney can also ask them to provide examples of how they’ve resolved technical issues and their method to solve them. You want to know if they can be flexible and adaptable when presented with new challenges or problems, as this is one of the most significant qualities in an employee. How someone approaches a problem may depend on what resources are available, which means one will want to know if they take the time to research solutions before making decisions.

Another method to determine if someone is suited for IT work in Sydney is by determining their level of self-sufficiency.

Their ability to keep up with the changes will also be crucial.

In addition to the above, one should look for candidates with a holistic technical background. IT Recruitment Agencies in Sydney go for individuals proficient in languages ranging from C to R. Ideally, they should be able to keep up with the changes in technology and provide examples of how they’ve resolved technical issues in the past. This activity could include their experience in a team environment. It could also shed light on the documentation they’ve created or processes they’ve developed that have been adopted by other teams.

The IT department is vital to any business and can be the difference between success and failure. Therefore companies must hire the best people possible because they will directly impact your company’s bottom line. It’s critical to look for candidates who have experience working in an agile environment, articulate their experience in a team environment and check their technical knowledge. Lastly, ensure they can keep up with the changes in technology because that will ensure longevity for the company.

plantation shutters

 The advantages of investing in good plantation shutters are innumerable. With the size of the slats, the direction you open them, and the design you pick, shutters let you regulate the level of privacy, especially for rooms facing the street, and the quantity of light in the house. Additionally, they add a layer of security and function admirably as insulators, lowering your energy costs. Plantation shutters also increase the value of your home because they make it stand out from the competition and go with any decor, saving the new owners the trouble of finding window coverings that go with their interior design preferences.

    Hundreds of years have passed since the invention of plantation shutters, and they want to continue existing for hundreds more. Shutters were ranked as the top window decoration option in Britain in 2015, and sales have been increasing ever since, with no signs of slowing down four years later.

    Although you frequently see Instagram influencers showcasing their exquisitely styled houses with shutters in the backdrop, we speculate that this is also because shutters are appropriate for any home and any budget. In this blog, we are going to discuss the reasons why you should opt for plantation shutters.

Plantation shutters provide better light control compared to curtains

Light is a crucial consideration when deciding how to decorate your windows. Would you want more or less light? Shutters have the advantage of giving you complete control over the amount of light that enters your room. Additionally, you’ll need less artificial light because shutters provide you more control over how the light is distributed in your rooms than curtains and blinds, which will result in cost savings.

Conversely, solid wood shutters are a great option if you like to use less natural light and block out the cold. The ability of shutters to retain heat is also crucial for lowering energy costs.

Shutters are simple to maintain and clean.
