2. Challenges in Electronic Packaging Design
n Designing an electronic product is becoming complex with reduced time to
market pressure, range of standards to comply, demanding user needs and
ever existing pressure for reduction of cost.
n Electronic packaging which ultimately makes a product succeed or fail is
increasingly becoming complex due to reduction in size and cost of the
product, outsourced manufacturing and above all demanding user needs
n Electronic packaging design of a product is not just a design of the
enclosure but also the whole product which includes the PCB, cables,
assembly process, testing etc.
n Electronic packaging is impacted by factors like working environment, the
way the product is used, standards to be complied, materials that make the
product and how the product will be supported.
n This scenario essentially mandates a holistic approach to the Electronic
Packaging design of a product and to be treated as just an enclosure design.
n This presentation presents the highlights of a framework developed by D4X
Technologies for Electronic Packaging Design for the engineers to
understand and design the electronic packaging well.

3. Systematic Design - Need for a framework
n One contributing factor to the successful product design is the holistic
view of the product and its usage scenario. Most failures happen
because product’s usage and the working environment is not
understood fully at the time of design
n Most of the environmental issues impact the product and the
packaging is the main contributor for the failures.
n Product packaging is a combination of mechanical and electronics
component design. Successful product is the one which has harmonized
combination of packaging and electronics.
n To do a successful product design a design framework is essential
n A design framework will enable the designers to address all the issues
in a holistic way so that redesign and reworks are avoided.This enables
the first version of the product to work successfully in the field.

4. SCoPE TM
– A framework for Electronic Packaging Design
n SCoPE is a intuitive framework which enables the designers
to understand the electronic product well and design its
packaging successfully.
n SCoPE is based on the knowledge accumulated from
designing of multiple electronic products for different
domains. It is a heuristic framework with no hard
mathematics to learn
n SCoPE framework is based on four critical elements of a
product and the characteristics of each of the element.
n It is based on the characteristics of each element and how
they impact the Electronic packaging of a product.

5. SCoPE TM
– Framework for
Electronic Packaging Design
n Presented in the next few slides are the highlights of a
Framework developed by D4X Technologies Private Limited
to help designer address the Electronic Packaging Design in
a holistic manner
n The slides basically presents the elements that make up the
Framework and gives an overview of utility of the frame
work.
n Framework essentially is a process with Checklist and
Guidelines which is exhaustive and allows engineers to
address the issue of Electronic Packaging well in advance
and completely.

6. SCoPE TM
– Intuitive framework
SCoPE
TM
- Four essential elements of
electronic packaging design framework
n Shape – Product’s shape and associated characteristics
n Content – Material content of the product and the
characteristics of the materials
n Process – Processes used for fabrication,
manufacturing, assembly and preparation of
components in a electronic product
n Environment – Product’s working environment, user
environment, product support and environmental
compliance.

7. Shape
First element in the framework is the Shape of the product.
Primary factor that impacts the product the most, is the
physical shape of a product. Shape impacts six critical
elements in a product
n Aesthetics – How the product looks visually and how it blends with the
user environment
n Ergonomics- How the use of the product impacts the user especially in
aspects like fatigue, stress etc.
n Usability – How easy is to use this product. Especially by different types of
users and how effectively the user can use the product with little training
n Domain – Another critical element how the Shape is impacted by domain
( like Medical, Avionics, Industrial etc.) in the products work
n User – Shape is also impacted by the type of user, their profession and
their educational level. How the Shape should lend itself to a neutral
position so that it is easily used by all kind of users is a key to success of a
product.

8. Content
Second element is the contents in product especially the contents
other than electronics.
n Content represents the material used to manufacture the product especially the
material used for the packaging ( like Sheet Metal, Plastics, Cables and
Harness etc.)
n Characteristics of the materials used
n Impact of processes used in the packaging like welding, riveting, casting &
Pressure die casting, molding, surface finish like painting, powder coating and
anodizing
n Impact of product working environment on the material used like corrosion,
bleaching, chemical reaction etc.
n Domain impact on material ( like Aluminum alloy instead of aluminum in
aerospace applications, Special plastics for medical devices etc.) used.
n Compliance to environmental laws especially from recycling purpose. (Painted
plastic is not allowed as the plastics can’t be recycled safely! or metal inserts in
plastic cabinets!)

9. Process
Third element in the framework is the the processes used to manufacture the
product. Process includes assembly and manufacturing of the product as well
as manufacturing of constituents like enclosures, cables, subsystems etc.
n Subsystem manufacturing Processes that impact the product quality are
n Manufacture of cables and other accessories ( Crimping, Soldering, Pressfit etc.)
n PCB Assembly process (especially PCBs with on board mechanical parts like relays, motors,
transformers heat sinks etc.)
n Mechatronic subsystems which impact the product packaging
n Product enclosure manufacturing which covers sheet metals, casting, injection molding etc.
n Special materials like EMI/EMC gasket, heat sink compounds, glue etc.)
n Special processes like Sterilization, hardening process etc. for domain driven needs.
n Regulatory process for Medical (FDA) and Avionics (FAA) which layout basic guidelines
on design and manufacturing process as well as documentation.
n Product Field support processes – How the product will be supported in the filed for
repair. e.g. Any photocopying equipment needs to fixed in a short time and the design
and packaging should allow easy access

10. Environment
n Finally the environment which covers three different types of
environments
n Product working environment ( like industrial systems, out door
telecom systems etc.)
n User Environment – how the users use the systems ( like how
doctors use systems and the usage depends on the user’s
knowledge)
n Environmental laws – Global standards like RoHS,WEEE & REACH
who these impact the product packaging as most of the times
recycling impacts the product packaging
n Product safety – which covers mechanical safety like sharp
edges, surface finish etc., Fire safety like fire safe etc., and
electrical safety ensure product is electrically safe to use.

11. How to use the SCoPE TM
framework?
n The SCoPE TM
framework has two major steps
n Use the SCoPE Index work sheet to find which elements are
important and have impact on the product.This SCoPE Index
worksheet will help in assessing which elements in a product
needs to be addressed
n Element Work Sheet and Check List will help identifying the
elements in a product which impact the Product Packaging.
n These sheets help in arriving at the issues to be addressed at
the early stage of the design and address potential issues.
n Elements in the frame work need to be addressed by the
respective teams so that the solutions are unified and
consistent.
