Top 6 Signs Your Electronics Manufacturing Team Needs Soldering Training

Soldering isn’t a side skill in electronics manufacturing. It’s core to product quality.

If your team is struggling with rework, failing inspections, or producing inconsistent results, it’s not because they don’t care. It’s likely because they were never given the soldering certification training they actually need to do it right.

This post will walk you through 6 clear signs your team could benefit from IPC certification in soldering. You’ll walk away knowing exactly what to look for, and what to do next.

1. You’re Seeing the Same Defects Again and Again

Cold solder joints. Bridging. Insufficient wetting. If the same issues keep popping up during inspection or testing, that’s a big red flag.

Repetitive soldering defects usually point to one thing: inconsistent technique.

When technicians don’t know the why behind what they’re doing, mistakes repeat. IPC certification training fixes this by explaining not just how to solder, but how to evaluate solder quality using real-world standards.

When skills go up, repeat errors go down.

2. New Hires Are Struggling to Meet Production Standards

You can’t expect someone to produce clean solder joints if they’ve never been trained. Onboarding doesn’t work when the first time someone picks up a soldering iron is on the production line.

If new team members are dragging down output, it may be time to rethink what training looks like in week one. A short soldering certification course can raise the floor quickly and keep bad habits from setting in.

3. Your Scrap Rate Is Quietly Eating into Profits

Every time a board gets scrapped, money is lost. But most manufacturers don’t trace scrap back to specific root causes, so soldering issues get ignored.

If you’re discarding boards due to heat damage, lifted pads, or poor joints, you’re watching dollars disappear.

What you need is training that connects theory with application. Soldering certification courses do that by putting irons in hands and correcting mistakes in real time.

4. Your Inspection Team Plays Referee Too Often

When inspectors are constantly going back and forth with production, it’s not a process, but a breakdown.

A properly trained assembler should know what a Class 2 or Class 3 solder joint looks like before it ever reaches inspection.

IPC certification provides a shared language between techs, engineers, and inspectors. Everyone knows the standard. No arguing. Just quality.

5. Customers Are Asking Questions About Your Workmanship Standards

This one matters. If clients are starting to ask about your certifications, your capabilities, or your process controls, you might already be on thin ice.

More OEMs are requiring IPC certification as part of their vendor qualification process. If you don’t have it, you risk getting passed over.

Training isn’t just about performance. It’s about proof.

6. You’re Planning to Scale—or Already Have

The bigger your team gets, the harder it is to maintain consistency. Processes that worked at five techs break when you’re at fifty.

This is the moment to standardize training. Soldering certification programs let you set a baseline that’s portable, trackable, and auditable.

Growth without structure leads to chaos. Training brings it back into focus.

Conclusion

If any of these signs felt familiar, your team isn’t alone. Most electronics manufacturers hit these roadblocks. The good news is, they’re fixable.

A soldering certification isn’t just a checklist point. They’re tools that reduce waste, strengthen inspection confidence, and prepare your team for high-reliability builds.

4 Common PCB Design Mistakes And How To Avoid Them

Many of the most common mistakes in designing electronics often occur on the Printed Circuit Board (PCB).  Taking IPC online classes, especially the IPC 6012 certification online, will significantly help those who are working or want to work in the electronics assembly industry, steer clear of costly errors like the ones below:

1. Using The Wrong Landing Patterns

All PCB design tools contain libraries of the most commonly used electronic components.  Each library includes the schematic symbol and PCB landing pattern.

The problem occurs when a component not included in the libraries is used in the design, and you end up having to draw the schematic symbol and the PCB landing pattern manually, which is easily prone to mistakes.  

Being off by even a fraction of a millimeter in drawing a landing pattern will already affect the placement of the component on the board, making it extremely difficult to solder.  So, it’s crucial to just stick with components included in the design tool’s library.

2. Wrong Antenna Layout For Wireless Designs

For products with wireless technology, the layout of the antenna on the board is crucial.  An incorrect antenna layout prevents maximum power transfer between the transceiver and antenna.

A matched impedance is needed to achieve an optimal wireless antenna layout.  For this to happen, two conditions must be satisfied:

· A proper microstrip must be used to connect the antenna and transceiver

· The microstrip must be designed with a 50-ohm impedance to ensure maximum power transfer with the antenna.  This can be done by setting the microstrip’s width with a microstrip calculator.

3. Not Enough Width For Power Traces

To keep the board as small and compact as possible, engineers design the traces as narrow as it’s functionally viable.  The mistake occurs when a high current isn’t taken into consideration.  A minimum trace width won’t be able to handle a 500mA current flowing through it.

The width of the trace depends on several factors, like copper thickness and whether it’s an external or internal layer.  To avoid this mistake, be sure to use a trace width calculator to ensure the accuracy of the trace thickness.

4. Unmanufacturable Blind/Buried Vias

Electronic devices are getting smaller and smaller, and with that, also comes the shrinking of electronic components.  Smaller devices require smaller PCBs, and because of this, some designers use blind and buried vias to connect boards with at least four layers to decrease the board’s footprint.

While they’re useful in compacting the board, vias reduce routing space on every layer of the board.  Furthermore, it’s not that simple to use vias in your design because blind and buried vias have strict limitations on which layers they can connect.  That’s why it’s highly recommended to totally refrain from using them in your design.

Conclusion

By being aware of these mistakes, you’ll be able to avoid costly delays in production and produce high-quality PCBs.  Electronics manufacturing demands strict adherence to IPC standards, much of which is taught in IPC online classes.  

More specifically, when you take an IPC 6012 certification online with training, you’re going to have a good grasp on the principles of PCB design.  This will help you avoid committing the mistakes discussed in this article and pave the way for a successful career in the electronics assembly industry.

Quality Control: An Essential Element in Electronics Manufacturing

The electronics industry is a highly technical world that is evolving continuously. In order for evolution to succeed in an industry, quality should be a mandatory element. Thus, the manufacturing of electronic components should be regulated through the implementation of standard procedures for testing and identifying process and operational flaws, which are the major sources of product quality failure. This should ensure the quality of finished products that will lead to the minimization of vendor returns.

Ways to ensure the production of high-quality products include:

Selection of appropriate quality control methods

Defining the standards of quality for every product

Determining the quantity of products to be subjected to tests

Providing Quality Control Training to staff involved in the manufacturing process

Setting up a system of communication and reporting where concerns about defects, non-conformance to quality standards, possible corrective actions, and other issues are taken up

Quality Control is classified into three types

Incoming Quality Control (IQC)

It refers to the inspection, testing, and receiving of incoming materials from suppliers and vendors.

Line Quality Control (LQC)

It involves identification, checking, and possible segregation of defective components during the manufacturing stage. It works to ensure acceptability in the quality of finished products.

Outgoing Quality Control (OQC)

This works to ensure that finished products are highly acceptable in terms of quality, workmanship, and design. Products that pass through this stage are declared ready for packing and delivery.

The implementation of strict and systematic quality control systems carries certain benefits not only to the ultimate consumer but to manufacturers as well. These include:

Better position in the marketplace

More incoming customers

Loyalty of old customers

Brand success

Positive market rapport

Any business, including electronic manufacturers and electronic manufacturing service providers, should give quality control and assurance the significance they deserve. They are a major factor in every manufacturer’s success in the areas of branding, product reliability, market position, cost savings, and productivity. All these are important contributors to the realization of a company’s main objective – maximized profits.

Electronics manufacturing is a complex industry. It involves highly technical work that aims to produce high-technology products. The demand for its products is high, yet quality is highly regarded in this industry. To win a good place in the market, every electronic manufacturer or EMS provider must invest in

Important Things to Know When It Comes to Soldering

The word soldering always comes up when you talk about electronic stuff. It is one of the basic skills that any technician or Engineering course that involves electronics needs to learn and eventually master.  Even for a fact that soldering has become automated, hand soldering is still in demand. This is especially true when it comes to reworks, repairs, and maintenance. Automation also has limitations, and human intervention is still needed to see to it that the electronics products will be of high quality. Soldering really involves a material called solder that melts when placed on a hot object, then the melted solder cools and forms a bond between two items. The basic tool is usually a soldering iron with a soldering station.

Soldering can be hard at first, but once you get the hang of it, it is really easy. Keep in mind that you should heat the metal and not the solder. It's also important to know which piece to solder to which other pieces. This is vital because you may end up soldering a component in the area on the circuit board that is not really intended for it. You should also know each component, especially its polarity. There is a big tendency that the circuit will get damaged when the polarity of a certain component is switched. You'll be glad to know that you can undo a bad solder if you do make a mistake with solder. One method for fixing a mistake is to just heat up the bad solder and then suck it away with a solder sucker.

You must master the basic techniques in soldering quickly if you want to learn how to properly do it. The soldering iron is not a plaything and not something that you can leave on the corner or place anywhere. It is really hot, which can really burn or even cause a fire. The burn caused by the soldering iron is really painful, I know, because I have one on my wrist. The wound, like any burn, heals slowly and will really leave a scar. So always remember that you should be cautious when melting solder. It will remain hot for many minutes when you solder something, so always grab parts with pliers to avoid getting burned even after the soldering iron is removed.

Keeping your soldering tools clean is also important. To prolong the life of your soldering iron, you should perform preventative maintenance and regular cleaning. Clean the tip often with a bit of tip cleaner and a moist sponge or paper towel while your soldering iron is hot. You should do this so that you will not end up always buying a new soldering iron. Money is hard to earn, which is why you should know how to spend it wisely. Keep in mind that terrible joints are produced by a dirty soldering iron. And also always unplug your soldering iron as soon as you are done using it. This is to prevent burning it up to the tip and oxidizing.

You should undergo proper training to be able to improve your skills and learn the right ways of soldering. There are a lot of training centers that offer such courses. Only experience will tell you if you have soldered correctly, which is why you should practice your craft with passion.
