The Crucial Role of Soldering Skills in Today’s Industries

The ubiquity of electronic devices in modern life and the increasing demand for skilled soldering professionals continue to rise in the world of electronics. Acquiring soldering skills with an IPC certification is a great advantage especially when you are thinking of going into a soldering career in electronics manufacturing. Soldering forms the backbone of electronic connection that emphasizes the need for precision and reliability. Its concept as a specialized skill goes beyond basic DIY projects. 

Solder is a metal alloy used for electronics that combines tin and lead in different proportions, usually marked on the various types of solder available. Most melting of solder combinations does not occur simultaneously as fifty-fifty solder begins to melt at above boiling point, but it’s not fully melted until it reaches 216 degrees Celsius. In short, between these two temperatures, the solder exists in a plastic or semi-liquid state. But enough of the technical part, this blog is about the people behind soldering and the crucial role of having soldering skills in today’s industries. 

Let’s talk about soldering certification. As soldering requires a specific skill set and ability to work with precision, reliability, and quality, it also needs IPC certification which is globally recognized as the standard of excellence. Individuals with soldering certification are trained to have the skills and knowledge needed for integrity throughout the process of manufacturing. Getting IPC certification can lead to more independent, self-reliant workability and higher productivity. It also helps to provide the workers with the skills they need to grow in the workplace. A successful and rewarding career path may be in store for those who pursue a soldering certification.

There are four levels of soldering certification and we will discuss the benefits of each one depending on the current experience and role within the company. The order is on the increasing level of expertise. 

1. Certified IPC Specialist or CIS

This certification provides the candidate with a consistent understanding of the design or production criteria within a particular standard. This level of training and certification would greatly benefit assemblers, line operators, supervisors, engineers, and quality personnel who are looking to expand their knowledge and ability within a specific standard used in the electronics manufacturing industry. 

2. Certified Standards Experts or CSE

A CSE certification is a subject matter professional with a high level of knowledge and understanding of a specific IPC standard or group of standards. This certification focuses on detailed knowledge of a particular standard rather than skill development and is validated by rigorous timed testing to a particular standard rather than skill development and is validated by rigorous timed testing to demonstrate a fluid knowledge of the materials used in the soldering and manufacturing process. 

3. Certified IPC Trainer or CIT

This certification is aimed at those who are interested in or need to train others as CIS at their respective companies. This can also include faculty members of education and training institutions with a need to certify students as CIS as part of a curriculum or Licensed Training Center employees who have not met the criteria for being Master IPC Trainers (MIT). CITs are authorized to deliver and administer CIS-level training and certification exams to those who are attempting to gain IPC certification. 

4. Master IPC Trainer (MIT)

This is considered the highest form of training of the four levels of IPC certification. Once this advanced IPC training has been completed, an MIT can train CITs and CISs and provide the first level of technical and administrative support to their trainees. 

Certifications largely depend on one’s role within the company and where his/her career in the soldering and electronics manufacturing industry to going in the future. But if you are looking for a reliable IPC certification provider, Blakcfox is the best place to go. They are already known in this industry and continue to deliver quality training.

Basic Soldering Techniques and Tools You Need to Know

Hand soldering tin on electronics circuit board

Soldering is the process that requires practicing the most. It is also the process of filing one or more components one by one dissolving and running a solder in the joint. It can be applied to electrical and electronic projects, plumbing, and many others. It is not an easy task, so having IPC 610 certification is a must. It gives you an edge when you want to work in an electronics or manufacturing company. You must also be good at soldering techniques, it will help you make an excellent working circuit. If you want to get certified in soldering, check out IPC 610 certification near me. 

Let us know the different soldering techniques to get you familiar with soldering. There are two different methods of soldering. They are:

1. Soft Soldering. It is a method of joining metals with eutectic tin or lead alloy. Metals like copper, brass, lead, tin, and steel are readily soldered but some metals like aluminum and cast iron both require special solder. A gas torch is usually used as a heat source for soft soldering.  
2. Hard Soldering. It is taken to include those metal joining techniques in which a filler rod is used as the joining medium. Heat is provided by a gas torch and there is no melting of the parental metal. It included silver soldering and brazing but not welding. Not let’s get to know these two:

1. Silver Soldering – It is the process of joining metal with melted silver solder. Heat is applied on the silver solder to melt and apply it on a prepared joint. It is essentially used for joining  silver but it can also be used to join other metals such as copper, brass, and gold.
2. Brazing – In this procedure, connecting two terminals of the base metals could be formed by liquid metallic space filler. The filler runs by the attraction of a vessel through the joints and cools down to give a solid union through diffusion and atomic magnetism. In addition, it produces a very strong joint and makes use of a brass metal as a space-filler agent.

There are tools that you need in soldering. 

1. Soldering iron – is used as a heat source for liquefying solder. For soldering heavy components and cable, you require electricity to bring the tip of the soldering iron to a high temperature. In short, a soldering iron device is used for soldering electronic components by hand. 
2. Solder Flux – Soldering flux is a chemical substance used to prepare the metal surfaces before soldering. It cleans metals by removing any oxides and impurities.
3. Soldering Paste – It is a mixture of powdered metal solder particles and sticky flux with the consistency of putty. In the electronics industry, it is used to connect surface mount components to pads in the manufacture of printed circuit boards.

The 3 Different Levels of Acceptability of IPC-A-610

• 

The Standards of IPC-A-610 which is described as “Acceptability of Electronic Assemblies” classifies electrical and electronic assemblies based on the intended use of the electronic product manufacturer. Towards this end, IPC has established three end-product classes to define these in terms of quality, functional performance requirements, inspection, and testing.

 

This product classification enables an end- user to define the product class of every assembly it has inspected. When placing an order. the end-user should specify in its procurement documents the classification of the electronic  product it wants to buy.

 

To make this possible, both parties should be aware of the quality standards of IPC-A-610 “Acceptability of Electronic Assemblies”. Companies affected by the current COVID-19 pandemic may make their key production or quality assurance personnel avail of the IPC 610 certification online.

 

These are the three product classes of electronic assemblies pursuant to the standards of IPC-A-610:

 

CLASS 1 – General Electronic Products

 

This category is intended for electronic assemblies that are to be used for the manufacture of cheap toys and other electronic products that are not expected to last long.

 

CLASS 2 – Dedicated Service Electronic Products

 

It is the classification given to products that designed for continued performance and long life. Products that are not critical but are expected to deliver uninterrupted performance use assemblies from this category. Cell phones and some computers belong to this class.

 

CLASS 3 – High Performance/Harsh Environment Electronic Products

 

This class is given to electronic assemblies that are used on products that are required to deliver continued high performance. Examples of products that need class 3 electronic assemblies include life support equipment, medical devices, aircraft, and military equipment. Class 3 electronic assemblies are the most expensive of the three product classes.

 

Knowing how IPC works helps both electronics manufacturers and equipment manufacturers to speak the same language especially when it comes to product classification. If you really want people in your production department to master IPC, you should send your key personnel a training that can lead to IPC specialist certification.

 

Any provider of electronics manufacturing services (EMS) that seriously wants to comply with IPC standards will certainly consider the implementation of training programs. This will widespread awareness of the quality standards that are acceptable across the electronics industry.

 

Awareness of quality standards like the IPC-A-610 is tailored not just for inspecting the quality of the end products; it is also designed for people building them. This makes everyone involved in manufacturing process “stay on the same page and speak the same language.” It makes monitoring of processes easier and spotting flaws better. This can be achieved by having IPC-certified in-house trainers who will ensure that IPC quality standards are understood and implemented.

 

As an original equipment manufacturer or electronics manufacturing service provider, it is highly important for you to fully understand the basic principles that make each of the three product classes separate and distinct from one another.

 

Both the OEM and EMS should know these standards. This allows the former to specify what to expect, and the latter to understand the level of quality of the products he needs to produce and deliver.

 

Training and certification for other equally important IPC quality standards such as IPC-A-620 “Requirements and Acceptance for Cable and Wire Harness Assemblies” may avail of the IPC 620 certification online offered at select IPC-certified training centers worldwide.

5 Common Soldering Mistakes And How To Avoid Them

Hand soldering is the core skill of every electronics enthusiast and professional.  As components become more compact over the years, it is crucial to have precise soldering skills, as the chances of soldering issues occurring are much higher.

The ideal solder joint must have good and complete wetting and a shiny and clean concave fillet.  It’s the same for through-hole components, and surface mount solder joints.  Through-hole solder joints specifically, look like the shape of a Hershey kiss.

IPC online training courses are designed to reduce assembly issues.  Taking an IPC 610 certification online is explicitly required for inspectors, operators, and trainers to maintain standards in electronics assembly.

That being said, one can learn and practice proper soldering and avoid the following mistakes:

1. Insufficient Wetting Of Pad And Pin

Wetting is the condition of the solder reaching its ideal fluid state, making it easy for a component to form a secure connection with the board.

When pins and pads aren’t wetted enough, solder doesn’t flow properly, leading to gaps and exposed spaces in the through-hole.  This can be fixed by cleaning the board thoroughly and applying even heat to the pad and pin with the tip of your soldering iron.

2. Disturbed Joints

Disturbed joints happen when the board is not stable, or when there’s a lot of movement while the alloy is solidifying.  They usually look rough or frosted and have a ripple pattern on the solder joint surface.

This can be fixed by reheating the joint and letting the alloy cool without moving the joints, or the board itself.

3. Solder-Starved Joints

A solder-starved joint is exactly as its name suggests.  You do not have enough solder to cover the through-hole, therefore not forming a stable electrical connection.  This makes the joint much more susceptible to cracking and electrical malfunction.

This occurs when you don’t apply enough solder to the joints, and can be resolved by simply reheating, the joint, and adding more solder.

4. Untrimmed Leads

Untrimmed leads of electrical components may cause short circuits if they come into contact with other leads or nearby traces.

This can easily be fixed by simply trimming the leads at the solder joint tops to avoid any risk of it bending and causing short circuits.

5. Cold Solder Joints

A cold joint has the appearance of a dull, lumpy, and rough surface.  It results from insufficient heat applied to the joint, making the solder not melt completely.

This could be caused by either a soldering iron that’s not hot enough or maybe a flaw in the design of the pads and traces itself. Leaving cold solder joints unfixed might result in cracking and failure over time.

This can be resolved by reheating the joint with a properly heated iron and removing excess solder.

Conclusion

Soldering mistakes can be avoided with proper training and certification.  Taking an IPC 610 certification online with IPC online training will benefit those who are working or want to work in the electronic assembly industry. It can give them a better capability to help their company by way of an improved product quality and increased efficiency. In turn, this can also help advance their careers.

The Benefits of IPC Certification to the Electronics Industry

Many Emerging Original Equipment Manufacturers and Electronic Manufacturing Services have evolved from a small local shop into a big player in the industry. This growth triggered system and management changes. This compels these companies to adopt new practices to be able to compete with the other players.

 

In this new playing field, it is important for you to understand that efficient production is an important element of business success. To make things work for a better business, you need to hire IPC-trained personnel and send your existing staff to IPC certification training to be able to stay relevant and competitive. That’s how business works. You should be on top of the game to be able to fight competition and earn the trust of the market. One of the ways to reach this goal is to coordinate with a trusted IPC training center and be certified as a quality manufacturer of electronic assemblies.

 

There are three main benefits of IPC certification especially in the field of electronic assemblies and inspection. These are:

 

1. Consistent Production of Quality Products

 

Consistency plays a major role in the success and profitability of a business. In the visual and inspection of electronic assemblies, this can be achieved.

 

Consistency is key to profitability and industry success. This can be realized by implementing standards and guidelines for the consistent production of quality products. The best way for a company to benchmark quality standards is to maintain an IPC certification in the visual inspection of electronic assemblies. The resulting quality of the finished products leads to customer satisfaction and high probability for repeat business.

 

2. Improvement in Cross-Channel Communications

 

Miscommunication has many negative consequences. In the electronics manufacturing industry, it can result in delayed or inconsistent production, and this can translate to millions worth of low-quality products and lost business opportunities.

 

The use of the same terminology and having the same standards of quality is important for vendors and manufacturers in the electronic industry. This is one of the advocacies of IPC – to make language and standards of quality uniform for all players in the industry and on all levels of any organization.

 

3. Reduced Costs

 

A company that is able to achieve consistency in quality and quantity as well as a streamlined cross-channel communications will certainly attain reduced costs. Consistent quality and quantity makes fewer rejects, increases revenues and minimizes customer returns. Good communication between industry players on the other hand makes way for accuracy when it comes to product specifications. This translates to the delivery of the right raw materials and the production of quality finished products. A lot of factors can mean added cost, and these include defective raw materials, low-quality finished products, product returns, rework which means additional man-hours, and accidents. These factors usually happen to companies that are not guided by product quality and acceptability standards.

 

As a company engaged in the production of electronic assemblies, you must be certified by a body that imposes strict quality guidelines. It will certainly benefit your business – and your employees will thank you for it.
