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.
