The Role Reverse Engineering Plays in Electronic Manufacturing Services


Reverse Engineering is the process of identifying the components of a system and their relationship with one another by thorough analysis to duplicate or upgrade the system. The system may be an existing component, subassembly, or product. And the process of Reverse Engineering is carried out without the help of drawings, documentation, or computer model.

Reverse Engineering is not as easy as it sounds and it mandatorily requires a good knowledge and experience of circuitry. This entails:
  • Understanding engineering sketches and specifications 
  • Electronic analysis of the system 
  • Component obsolescence analysis 
  • Component material analysis 
  • Dimensional analysis 
  • Process variation of the reverse engineered system 
Deconstructing a finished product to determine how parts fit together and how the system works can guide us a great deal about analysis, design, development, testing, and maintenance of the system.

The Systematic Process of Reverse Engineering

  1. Identification and analysis of the machine’s components and their relation to one another. It constitutes analyzing each component’s electromagnetic interference, radio frequency, control loops, and communication and contacts between parts.
  2. Make the diagrammatic representation of the information discovered while studying the components.
  3. With the help of the diagrammatic representation, create a physical version by reassembling parts.

Say, if you are the Developer…

You can have a thorough working knowledge of all the individual components and how they function together only when you think like a developer. When it comes to performance, a redesigned or remanufactured machine can have an inferior performance due to a simple deviation from the original calibration. It is important that the current machine, despite some degraded performance meets the recommended specifications. Close analysis of the components would help you to determine whether design or chip technologies must be updated or replaced, or whether designing additional programs or fine-tuning existing programming would align to your requirements. And once you have reverse engineered, determine whether the system meets your requirements.

Reverse Engineering: Facilitating Decision Making

Reverse Engineering forms an integral part of Electronic Manufacturing Services. When all the working parts are disassembled and reassembled, or minimum considered in terms of function and performance, you can gauze a lot about analysis, design and development, and maintenance of the system. This facilitates efficient decision-making process along with saving time and money. From the analysis, we may find that only a few parts require a change in design, or maintenance. Thus, we can formulate a plan only for these parts and deploy them.

Circumstances That Influence Your PCB Assembly Quote

Image
While working on PCB fabrication and assembly, numerous situations go along. There are times where you even end up with an expensive quote if you are not vigilant about the executed choice. But need not to worry, as you can adjust your Printed Circuit Board Assembly request to get a better quote for your project. The only thing you need to be aware of is what factors are influencing your PCB assembly quote. Due to the number of components and their types, there will be a change in the prices. However, the cost fluctuates depending upon the component type and technology preferred by the consumer. Here are some key factors to keep in mind the next time you order prototype PCBs, so you know what makes your PCB assembly quote fluctuate. Factors impacting the cost of a prototype PCB assembly Depending on the project parameters, the cost of prototype PCBAs varies. For instance, the size of a standard Printed Circuit board will typically be less expensive than custom dimensi

Distinct Advantages Of Small Batch PCB Assembly

Image
PCB prototyping is at an all-time high, with Printed Circuit Boards becoming an integral part of more and more devices. As organizations continuously innovating, the need of the hour is small batch Printed Circuit Board Assembly that offers high turnaround times without the manufacturer getting stuck with high inventory. To know more about small batch PCB assembly , let us have a look at its few distinct advantages that are of immense value to a manufacturer: Cost advantage In an ever-changing technological scenario, where economies of scale are known to accrue with a high volume of production, low volume PCB production comes with significant cost advantages. For one, you will not land up getting more boards produced than you require. Also, with changing technology, the boards might not be rendered excessive. At the prototype stage, you are often improvising on the product, both regarding design and functionality. Low batch production means you not impaled with faul

Advantages of Using PCB Prototyping Service Ere Final Production

The time-consuming and complicated process can prove to be the hindrance while creating a new PCB-based solution. Thus, reduce in time and cost associated with the development process can significantly improve the chance of success in your upcoming projects. In this article, we'll talk about the benefits of building your design verification with prototype Printed Circuit Boards, edges of shifting to standard-grade PCBs after validating your design. Before launching a full production run, ensure that your printed circuit board (PCB) is operating accurately, given a fact, how cautiously designers work on the project. As minute mistakes and vague problems always pose a threat to the functionality of the final product. If these problems are not captured before full production, it can prove to be expensive for the project as a whole. As a result, many engineers frequently order prototype boards before full-scale manufacturing. However, with recent technological advancemen
