equivalent of 2 series capacitors. If one of these should fail
short-circuit, there is still capacitance end to end and the chip will
still function as a capacitor, although capacitance maybe affected.

Surface mount capacitors
1.4 - FlexiCap™ termination
MLCCs are widely used in electronic circuit design for a
multitude of applications. Their small package size, technical
performance and suitability for automated assembly makes
them the component of choice for the specifier.
However, despite the technical benefits, ceramic components
are brittle and need careful handling on the production floor.
In some circumstances they may be prone to mechanical
stress damage if not used in an appropriate manner. Board
flexing, depanelisation, mounting through hole components,
poor storage and automatic testing may all result in cracking.
Careful process control is important at all stages of circuit
board assembly and transportation - from component
placement to test and packaging. Any significant board flexing
may result in stress fractures in ceramic devices that may
not always be evident during the board assembly process.
Sometimes it may be the end customer who finds out - when
equipment fails!
Syfer has delivered millions of FlexiCap
TM
components and
during that time has collected substantial test and reliability
data, working in partnership with customers world wide, to
eliminate mechanical cracking.
An additional benefit of FlexiCap™ is that MLCCs can
withstand temperature cycling -55ºC to 125ºC in excess of
1,000 times without cracking.

fibrous nature of the

stress.
Syfer has the solution -
FlexiCap™
FlexiCap
TM
has been developed as a result of listening to
customers’ experiences of stress damage to MLCCs from
many manufacturers, often caused by variations in production
processes.
Our answer is a proprietary flexible epoxy polymer termination
material, that is applied to the device under the usual nickel
barrier finish. FlexiCap
TM
will accommodate a greater degree
of board bending than conventional capacitors.
Available on the following ranges:
All High Reliability ranges
Standard and High Voltage chips
Surge Protection and Safety capacitor chips
3 terminal EMI chips
X2Y Integrated Passive Components
X8R High Temperature capacitors
Syfer FlexiCap™ termination
All ranges are available with FlexiCap™ termination material
offering increased reliability and superior mechanical
performance (board flex and temperature cycling) when
compared with standard termination materials. Refer to Syfer
application note reference AN0001. FlexiCap™ capacitors
enable the board to be bent almost twice as much before
mechanical cracking occurs. Refer to application note AN0002.
FlexiCap™ is also suitable for Space applications having
passed thermal vacuum outgassing tests. Refer to Syfer
application note reference AN0026.

Summary of PCB bend test results
The bend tests conducted on X7R have proven that
the FlexiCap
TM
termination withstands a greater level of
mechanical stress before mechanical cracking occurs.
The AEC-Q200 test for X7R requires a bend level of 2mm
minimum and a cap change of less than 10%.

For customers currently using standard terminated capacitors
there should be no requirement to change the assembly
process when converting to FlexiCap
TM
.
Based upon board bend tests in accordance with IEC 60384-1
the amount of board bending required to mechanically crack
a FlexiCap
TM
terminated capacitor is significantly increased
compared with standard terminated capacitors.
It must be stressed however, that capacitor users must not
assume that the use of FlexiCap
TM
terminated capacitors will
totally eliminate mechanical cracking. Good process controls
are still required for this objective to be achieved.
FlexiCap MLCC cross section
FlexiCap™ benefits
With traditional termination materials and assembly, the chain
of materials from bare PCB to soldered termination, provides
no flexibility. In circumstances where excessive stress is
applied - the weakest link fails. This means the ceramic itself,
which may fail short circuit.
The benefit to the user is to facilitate a wider process window
- giving a greater safety margin and substantially reducing the
typical root causes of mechanical stress cracking.
FlexiCap
TM
may be soldered using your traditional wave
or reflow solder techniques and needs no adjustment to
equipment or current processes.

Multilayer ceramic capacitors typically require sintering temperatures
in excess of 1000ºC, which presents no problems to capacitors that
employ a Precious Metal Electrode (PME) system. However, for Base
Metal Electrode (BME) systems additional processes are required,
including the use of a reducing atmosphere to prevent oxidation of the
electrodes.
Despite the manufacturing problems, BME multilayer ceramic
capacitors have proven to be a good choice for commercial products as
they have reasonable electrical properties and life expectancy and can
be used for some high reliability applications when properly qualified
and screened.
At Syfer Technology we have been developing PME systems for over
thirty years and use them exclusively for all our product lines. It
produces capacitors to the highest reliability that can be used in all
applications including the very demanding space requirements.
A recent Highly Accelerated Life Test (HALT) programme was
undertaken to compare Syfer PME with equivalent BME capacitors.
Capacitors rated at 50 volts were tested at 400 volts and at a
temperature of 180ºC. The programme used three capacitor types
from Syfer and two BME manufacturers.

In all cases the Syfer PME parts out-performed the BME capacitors
suggesting that the long term reliability of PME systems is superior to
BME, and PME parts should be regarded as the component of choice
for high reliability applications.
