Electronics Design in Melbourne: Common Mistakes to Avoid

The majority of executives are responsible for managing the performance of the product or warranty returns. They are also the ones who can tell that the most common cause of headaches in manufacturing often comes from manufacturers and suppliers. Reliability in electronics design in Melbourne is very important as it can make or break the product. Design has an integral role to play in the product’s manufacturability. The easier it is to manufacture, the better will be its tolerance to standard variations in manufacturing processes.

Moreover, it has a role to play in component reliability as those designs that avoid the use of extended value components, lessens the application of electrical and thermal stresses can help reduce the risk that marginal components would induce product failure.

 

Flex cracking

This mistake usually occurs when the printer circuit board (PCB) under a ceramic-chip capacitor extremely bends. This capacitor is not capable of responding to cracks and strains. Flex events could happen during testing, depaneling, card insertion, attachment or from accidental dropping or mechanical shock. The approach to this will depend on the design constraints, cost constraints, as well as the degree of acceptable risk.

 

Custom Connections and Joint Wear

Some extensive design for reliability efforts are highly focused on avoiding wear out. One of the best approaches to this is to assess robustness in the design phase by deriving predictions based on the first and second order models.

Designers of PCB only think in two dimensions. But in some applications, heat sources that separate from electronics could be hot or close enough to cause a serious temperature rise. A designer might forget about such heat sources during modeling and might not install them during testing only to find out that they can actually cause solder joints to wear out.

 

Electrolytic Capacitors

Most designers like an electrolytic capacitor for its high capacitance. On the other hand, they may hate it as they tend to fail over time. Such love and hate relationship have led to a wide range of methods for predicting and derating lifetime. So, what will be the best approach to this? This will be dependent on whether you plan on derating voltage, temperature, or ripple current. Given this, you have to keep in mind that an electrolytic capacitor will work best when voltage is applied to it. Without voltage, it will have no capacitance and dielectric.

Designing for the purpose of reliability can be a bit of a challenge. It plays an important role in great success of a product as well as the company’s bottom line. It is important that you assess the evolving design, solve problems before they become worse, and find potential weaknesses. Addressing and recognizing possible problems would prevent the serious issues along the way. With this, you will be worry-free so you can better sleep at night.

 

Electronic Design Sydney: What Is It?

Electronic designers are the main producers and creators of modern automotive, military-based, and consumer electronics. These designers are responsible for the many products that we are using today such as cellphones, IPods, PCs, laptops, etc. The decisions they make great affects our daily lives, especially when it comes to the features that a certain product will have, how much will it be, and how it can perform.

 

Electronic Designer: What does One do?

The main objective in an electronic design in Sydney is to come up a reliable, working, and low-cost solution that will meet the requirements of the customers. The production of these products is explained by observing the electronic design life cycle. Here is an example of how this cycle looks like.

 

Phases of Electronic Design Life Cycle

Requirement Phase

Gather all possible information from the customers or a group about the specifications and features that are desired for a specific product.

 

Detailed Design Phase

Basing on the requirements, choose key components like graphical processing unit and micro processing unit if needed. Aside from this, design each individual sub-circuit needed to perform specific features or tasks. All these should be compiled into a master schematic.

 

Prototype Creation

The master schematic should be passed off to printed circuit board designers for prototype development. The designers would then proceed to help the PCB designers in tracing the layout of critical and sensitive circuits.

 

Test Phase

Be sure to confirm that the newly created prototype is functioning well and all circuits are meeting the requirements. Also, a product durability test should also be done such as drop testing, vibration, thermal shock, and halt in order to confirm the integrity of a product.

 

Evaluation Phase

Make a list of all non-compliant bugs or circuits with products. Basing on the overall functionality and evaluation of requirements, decide if you will produce the product in mass quantity or otherwise. In case the product fails, the production will be skipped and the life cycle will be restarted again.

 

Production Phase

At this point, the product needs to be guaranteed so it meets the satisfaction and requirements of the clients. Then, the product will be mass produced and the electronic design Sydney designer will be supporting the production in case of any trouble. He may also help in the creation of mass quantity testers so the functionality and integrity of units will be confirmed.

 

Phase Summary

The list above summarizes an example of what an electronic design life cycle looks like. All of these will depend on the specific company, as well the product that is created. If the customers are satisfied and all their needs are met, the process can be repeated for new production revisions.

Electronic design plays a major role in many industries and by understanding what it is, its uses, as well as the advantages it brings, you can better make the most out of it.
