PCB Reverse Engineering

PCB Reverse engineering 

PCB Reverse engineering is the process of analyzing an existing product or design for the desire & purpose of replicating the similar functionality or the behavior without the aid of original manufacturing or actual design documents. It’s a challenging task as the information given is limited and the task requires committed experienced professional to start from minimal information to the cusp where the production of the new design can take place.

Do we have any standard to govern PCB Reverse engineering?

Before understanding the steps used for PCB Reverse engineering, let’s understand, is it ethical to use Reverse engineering or are there any standards which mentions about reverse engineering ?  Reverse engineering as such is a wide term and is applicable in multiple fields of mechanical engineering, electronic engineering, software engineering, chemical engineering, and systems biology.

From software perspective In 1990, the Institute of Electrical and Electronics Engineers (IEEE) had defined reverse engineering as “The process of analyzing a subject system to identify the system’s components and their interrelationships and to create representations of the system in another form or at a higher level of abstraction”, where the “subject system” is to be considered as the end product of software development.

In electronic engineering there is as such, no standard or guidelines which mentions about reverse engineering. Jerry can, Panzerschreck, Tupolev Tu-4, SCR-584 radar, V-2 rocket
BGM-71 are historic few examples which are reverse engineered to make similar powerful weapons.

Top Reasons for Reverse Engineering.

  1. Obsolescence : Obsolete part replacement
  2. Interfacing of different parts of system.
  3. Product security analysis.
  4. Cost Optimization
  5.  Re-positioning of obsolete components.
  6. Competitor Analysis and gain

Tools used for PCB Reverse Engineering

  • Good multi-meter
  • Continuity Tester
  • Inductive short tracer
  • Milli-Ohm meter
  • Microscope
  • Light panel  & Torch for detailed PCB inspection.
  • X-Ray imaging of PCB
  • Lot of Patience & Passion
  • Steps for PCB Reverse Engineering

    • Assign reference designations (U, J, R, C, D) to unmarked components before starting PCB reverse engineering.
    • Create a Component level BOM
    • Design -Identify the system’s components and their interrelationships.
    • Components Placement & Mechanical
    • XY locations of Connectors, LED, Switches etc
    • Board mechanical Mounting holes & any special cuts on Boards, Board size etc
    • Download datasheets, application notes, and architecture information
    • Create net list
    • Make the Schematic Drawing and PCB Layout

    PCB reverse engineering is grueling process which seems impossible sometimes but right experience, dedication and success gives paramount satisfaction and overshadows the hurdles faced in the journey.   .

How to calculate target cost for Electronic Products?

Target costing is a critical factor in product design and development. It not only gives idea about the final product but also helps in assuring the success of the product in the market. How to calculate target cost for Electronic Products? Before going into the specifics the brief  life cycle of electronics design and development of a new innovative product can be outlined as below.

Generic Life Cycle of Electronic Products

  1.    Idea of a product
  2.    Market Analysis  – Marketing Requirement document
  3.    Target Costing : How to calculate target cost for Electronic Products ?
  4.    Requirement design – Product requirement Design document
  5.    Quotes for design and development – Technical Proposal
  6.    Prototype build – Design, verification and manufacturing of prototype

Historical Origin of Target costing

Target costing is believed to be originated in Japan in the 1960s and since the 1980s Western companies in North America and Europe have tried to adopt target costing albeit over the years many variations of target costing have been developed and are being used in different countries. ““Value engineering” is another similar known concept from Americans which emphasizes on maximizing desirable product attributes while at the same time minimizing product costs (Leahy, 1998).

How to calculate target cost for Electronic Products ?

The principle of target cost starts with finalizing of selling price of a particular product and work back to the cost by removing the cost of profit. The design and manufacturing teams are vital for this as the emphasis is given from the design and planning stage, so that the apt decision are made to determine the price and feature combinations suitable for the product and profitable for the customers.

Factors which affect costing 

  • The Mandatory features of the product
  • Good-to-have features
  • Bill of material, PCB costing : No of components
  • Environment Requirement :  Russia or South Africa, inside water or top of mountain
  • The complexity of design and ease of manufacturing
  • Enclosure design and material
  • In-house expertise and sub-contracts
  • Batch size and packaging, shipping costs

The concept of value  analysis is of prime importance here as it aims to reduce costs by identifying those area of a product or service which even if removed does not affect “user value/ function” or “esteem value/brand value” of the product.

Cost of a unit can be worked out by taking cost of all above and desired profitability.  Conventional costing records costs only as they are incurred but target cost gives flexibility and ability for cost control and increase the margins as per demand of the market.

Argus product development process involves focus on value engineering and target-costing for electronic products to make it viable for customers and consumers equally.
