Today, plastic packaged integrated circuits are ubiquitous even for high-reliability applications. Reliability testing and standards play a key role in reliability engineering to achieve the necessary reliability performance. Traditional stress-based standards are easy to use but often over- or under-stress units and don’t focus on key vulnerabilities, particularly moisture-related ones. Knowledge-based standards have evolved to fix this, but rely on knowledge of mechanisms, control of board manufacturing conditions, and understanding and specifying end use conditions. This motivates a survey of plastic package mechanisms and testing with particular focus on moisture-related mechanisms and testing. The moisture-related examples will cover HAST testing, and the “popcorn” mechanism.
Learning Objectives
1.Understand the philosophy and methods behind reliability testing of ICs as applied to plastic-packaged ICs.
2.Learn the historical development of the JEDEC temperature-humidity-bias (HAST) moisture reliability testing standard.
3.Get a practical overview of key thermal, thermo-mechanical, moisture (chemical), and moisture (“popcorn”) mechanisms.
4.Appreciate how transformation of environmental conditions to conditions at the site of failure in the package is used to “scale” reliability models.
If you use hollow plastic parts (aka water bottles or any other type of bottles), then you're using products made from blow molding. Read this slideshare to learn more about blow molding!

2. Introduction
• In 1907 Dr. Leo Baekeland achieved a reaction
between Phenol, a caustic, crystalline acidic
compound and Formaldehyde, a colorless,
pungent gas, by heating these ingredients
under pressure in a reaction kettle.
• The resultant, hot liquid when cooled, became
a hard brittle solid. It lacked physical strength,
but possessed excellent thermal, chemical and
electrical insulating properties
3. Introduction
• The hard brittle resin in a pulverized from
could be mixed with fillers, reinforcement,
colorants, lubricants and catalyst. The end
product was a molding compound capable
of further processing on heated mills and
calendar mills.
• Thus the first thermosetting molding
compound was created.
4. Introduction
• In the following years additional thermoset
resin systems were developed to meet the
requirements of diverse applications in
automotive, communications,
construction, transportation, household
appliances, business machines, aircraft
and aerospace fields.
5. Thermoset Definition:
• A polymeric material which can be
formed by the application of heat and
pressure, but as a result of chemical
reaction permanently crosslinks and
cannot be reformed upon further
application of heat
– Chemical crosslinking must occur for the
resultant product to be called a thermoset.
– Monomeric precursors may or may not be
polymeric
7. Classifications
• General Purpose – Average mechanical
properties, lower resistance to heat, higher
coefficient of expansion, low cost and
commodity production.(Phenolics, Aminos and
polyesters)
• Engineering – Higher mechanical properties
and temperature resistance and more durable.
More expensive with moderate production
rates. (Epoxies and Polyurethanes)
8. Classifications
• Specialty – one or more highly specific
and unusual properties. Very expensive
and produced in small quantities.
(Silicones, Allyls, Crossedlinked
Thermoplastics)
9. General Properties
– Thermal and dimensional stability
– Electrical insulation
– Chemical resistance
– High flexural modulus
– Toughness
– Surface hardness
– Moldablilty
– Cost effectiveness
11. Introduction
• First thermosetting plastic, first synthetic
commercially available plastic resin
• Produced by chemical reaction between
phenol (resin) and formaldehyde (curing
agent)
• First made by Dr. Leo Baekeland in 1907
• By far the most widely used of all
thermosets for molding applications
12. Chemistry
– Phenol – Formaldehyde resins are general
purpose thermosets formed mainly by the
polycondensation reaction between phenol
and formaldehyde
– Resole process, other main process is
Novalac
– Raw Materials
• Phenol
– Show phenol structure
• Formaldehyde
– Show formaldehyde structure
16. Phenolic curing process
• The curing process to the final thermoset
material can be initiated by just heating the
resin in a mold above its gel temperature
• When heated, the resin forms larger
molecules without the use of additional
catalyst
• The reaction is a typical polycondensation,
since water is given off as a by product
18. Processes that use Phenolics
• Compression Molding
• Transfer molding
• Injection Molding
19. Properties of Phenolics
• Physical
• Excellent dimensional stability
• Low water absorption
• High surface hardness
• High creep resistance
• Mechanical
• High compressive strength
• High modulus, stiffness
20. Properties of Phenolics
• Thermal
• Phenolics retain a high percentage of properties
at elevated temperatures
• Low coefficient of thermal expansion
• Good heat resistance
21. Properties of Phenolics
• Electrical
• Good electrical resistance
• Chemical
• Good chemical resistance
• Other
• Good weather resistance
• Easily molded
• Good machining properties
24. Introduction
• There are three fundamental molding
processes for thermoset compounds.
– Compression molding
– Transfer molding
– Injection molding
• The process used will be determined by
which process can produce the part to
appropriate specifications at the most
economical rate
25. Production Methods and
Equipment
• The choice of methods and equipment
for use in the production of thermosetting
molding compounds is usually
determined by the type of reinforcement
being used
• Reinforcements are added to thermosets
to improve properties. Impact, flexural
strengths, shrinkage, etc.
26. Compression Molding
• Introduction
– Uses a hydraulically operated press
– Press consists of two heated mold platens, one
stationary and one movable
– Platens have either “T” slots or tapped holes to fix
the mold halves to the platens
– Tie Rods, usually 4, provide for precise alignment
as the press is opened and closed
– The press open and shut height and the platen
temperature are controlled.
27.
28. Compression Molding
• Compression presses are rated by their
closing force capacities
• Can be manual, semiautomatic or fully
automatic
• Preform temperature, molding temperature,
molding pressure, molding time and cooling
time are the most important design
parameters
– Cavity depth is very important to achieve the proper
molded density
29.
30. Transfer Molding
• Similar to compression molding
• Four basic types
– Pot type transfer molding – old technology
– Plunger transfer molding
– Automatic Transfer molding
– Screw transfer molding
31. Pot Type Transfer Molding
• Mold design provides a “pot” into which the
compound, heated or unheated, is placed and
the press closed
• The clamping pressure exerted by the press
also forces the compound from the pot into a
runner system, then into the cavity
• Was innovative, providing an improved means
for certain parts and producing less flash at the
parting line
32.
33. Pot Type Transfer Molding
• Also made it possible to feed the molding
compound for a single location
• Produced a lot of waste due to pot
volume being 15% higher than the
runner and cavities volume, to overcome
the pressure needed to force material to
the runners and cavities
34. Plunger Transfer Molding
• Developed in early 1940’s to overcome
difficulties/expenses of the pot type
• A hydraulic cylinder is mounted on the top
platen of a standard compression press. It’s
the plunger
• The clamping pressure is used to keep the
mold totally closed while the top cylinder
provides the pressure required to force the
compound into the runner system and cavity
35.
36. Automatic Transfer Molding
• An attempt to integrate perform and
preheat as a function of press operations
• An overhead performer capable of
feeding a precise weight of perform
feeds a dielectric preheater directly
below
• The preheater feeds the compound to
the plunger
37. Automatic Transfer Molding
• The plunger feeds the mold
• Completely automatic, but confined to
the use of free flowing granular materials
• They have been slightly redesigned for
other materials
38. Screw Transfer Molding
• Uses an extruder to supply a precise
weight, temperature and density, shot,
that feeds into the mold on a completely
automatic basis
