Description
The present invention relates to a strip with
controllable electrical resistance. More specifically, the invention relates to
a strip with segments of conductive/static dissipative properties and its
applications.
Due to the miniturisation trend of the microchips,
many today's highly electrostatic discharge (ESD) sensitive devices are
extremely vulnerable to ESD. Therefore these chips demand a better and more
precise control of the body-to-ground electrical resistance to reduce the body
static voltage to a safe level to minimise such ESD damage in a typical
microchips manufacturing environment.
The use of conductive ground cord, conductive shoes,
conductive chairs, etc are some of the many options that can be utilised to
control and limit the amount of static charge that can be reside on a person's
body through controling the electrical resistance from body to ground.
While it is important to have good electrical
conductivity to ensure that static charge can be readily drain to the ground,
it is also equally important that the electrical resistance must be such that
it will not cause any electrical safety hazard to the person who uses these
modes of grounding.
There are numerous prior arts that disclose various
means of controlling electrical resistance. However, most of these prior arts
cited including EP 0361439, US 3473146, US3657692 and GB 1134823 are not that
simple and involve at least two or more substrates or more sophisticated design
to achieve the desirable control. The cost of these sophisticated structures
and materials are extremely high, which largely results in the difficulty of
its commercialization and promotion.
A strip with segments of conductive/static
dissipative properties which can be used for controlling electrical resistance
with simple design and low cost, substantially as shown in and/or described in
connection with at least one of the drawings, as set forth more completely in
the claims, providing an alternative solution tothe technical problem of
sophisticated design and considerable cost of the structure of
conductive/static dissipative properties of the prior technology.
The invention disclosed herewith is a strip having
an original electrical property falling in the range of 10e3 to 10e6 ohms
measured according to the ANSI/ESD STM 11.11. Then at least two cuts are made
on the strip. The first cut is made on first side edge of the strip and extends
in a direction towards the opposite second side edge, while the second cut is
made on the second side edge of the strip and extends in a direction towards
the opposite first side edge, the total length of the first cut and the second
cut added together falls between once and twice of the width of the strip and
are not in aligned with each other but slightly spaced apart in order to create
a tiny strip of conducting path.
In the above mentioned strip with segments of
conductive/static dissipative properties, the first cut and the second cut both
extends more than half of the width of the strip.
In the above mentioned strip with segments of
conductive/static dissipative properties, the first cut and the second cut are
of the same length.
In the above mentioned strip with segments of
conductive/static dissipative properties, the first cut and the second cut are
parallel to each other.
In the above mentioned strip with segments of
conductive/static dissipative properties, the strip futher comprises a third
cut adjacent to the second cut, which is made on first side edge of the strip
and extends in a direction towards the opposite second side edge, the total
length of the second cut and the third cut added together falls between once
and twice of the width of the strip and are not in aligned with each other but
slightly spaced apart in order to create a tiny strip of conducting path.
In the above mentioned strip with segments of
conductive/static dissipative properties, the strip futher comprises a forth
cut adjacent to the third cut, which is made on second side edge of the strip
and extends in a direction towards the opposite first side edge, the total
length of the third cut and the forth cut added together falls between once and
twice of the width of the strip and are not in aligned with each other but
slightly spaced apart in order to create a tiny strip of conducting path.
According to an aspect, a shoe sole of
conductive/static dissipative properties is provided, which comprises a strip
of any one stated above.
According to an aspect, an adhesive tape of
conductive/static dissipative properties is provided, which comprises a strip
of any one stated above.
According to an aspect, a mounting pad of
conductive/static dissipative properties, which comprises a conductive top
layer with a conductive property of 10e4 to 10e5 ohms, an insulative bottom
layer, and one or more mounting bands that comprise a strip of any one stated
above.
When implementing present strip with segments of
conductive/static dissipative properties and its applications, it is
interesting to note thatthe precise control of the electrical resistance
between two edges of the conductive strip is achieved by varying the space gap
between the cuts or varying the length of the cuts, without the need of doing
any additional design or additional work. Accordingly,the invention possesses
high commercial attractiveness as it can control the electrical resistance of a
strip with good accuracy in a simple and cheap way.
The accompanying drawings illustrate one or more

The present invention is more particularly
described in the following examples that are intended as illustrative only
since numerous modifications and variations therein will be apparent to those
skilled in the art. Referring to the drawings, like numbers indicate like
components throughout the views.
The invention disclosed herewith provide a simple
and practical means to fabricate a electrostatic discharge (ESD) strip or cord
with adequate precision in electrical resistance to effectively drain static
charge from body to ground readily and safely.
Figure 1 is a structure diagram of a strip with
segments of conductive/static dissipative properties according to an embodiment
of the present invention. Figure 2 is a diagram of a strip with segments of
conductive/static dissipative properties being measured according to an
embodiment of the present invention. Refering to Figure 1 and 2, the invention
starts with a strip of conductive material prepared by a conventional means by
coating, extrusion, moulding or any other conventional process. The electrical
resistance between one point (point A) and anorher point (point B) of the
conductive strip so prepared is exhibiting an electrical property falls in the
range of 10e3 to 10e6 ohms measured according to the ANSI/ESD STM 11.11 (USA).
Then a minimum of two cuts are being made on the strip. The first cut 1 is made
on a first side edge of the strip and the cut extends more than half of the
width of the strip in a direction towards the opposite second side edge as
shown in Figure 1. The second cut 2 is made starting on the second side edge of
the strip and extends more than half of the width of the strip in a direction
towards the opposite first side edge as shown in Figure 1. The first 1 and
second 2 cuts are not in aligned with each other but slightly spaced apart in
order to create a tiny strip of conducting path as shown in Figure 2. The first
cut 1 and the second cut 2 can be parallel to each other. Optionally, the first
cut 1 and the second cut 2 may be of the same length. Now the conductive strip
becomes two segments with the tiny strip electrically linking the two segments
together. Figure 1 and 2 are just for illustration, and in other embodiments,
the present invention may be achieved as long as the total length of the first
cut 1 and the second cut 2 added together falls between once and twice of the
width of the strip.
The new electrical resistance between point A and
point B is now depends on two variables. The first is the width of the tiny
strip which depends on the distance spaced apart between the two cuts. The
narrower the width of the tiny strip is, the higher the electrical resistance.
The second is the length of the connecting tiny strip which depends on the
length of the cuts being made. The longer the connecting tiny strip is, the
higher the electrical resistance.
By varying the space gap between the cuts or
varying the length of the cuts, we can more precisely control the electrical
resistance between point A and point B of the conductive strip without the need
of doing any additional design or additional work. This invention is simple and
low cost. It can be mass produced using any conventional die-cutting machine,
etc.
Optionally, a 'three-cuts' or more cuts technique
can also be used to achieve more flexibility of the invention like more
controllable electrical resistance, longer extensible strip, etc. as shown in
Figure 3 and 4. Figure 3 and 4 are structure diagrams of a strip with segments
of conductive/static dissipative properties according to another embodiment of
the present invention. Refering to Figure 3 and 4, the strip futher comprises a
third cut 3 adjacent to the second cut 2, which is made on first side edge of
the strip and extends in a direction towards the opposite second side edge, the
total length of the second cut 2 and the third cut 3 added together falls
between once and twice of the width of the strip and are not in aligned with
each other but slightly spaced apart in order to create a tiny strip of
conducting path.
However, the structure in Figure 3 and 4 is only
for the purpose of illustration but not limitation. Other structures can be
involved in the present invention as well. For example, the strip can futher
comprise a forth cut adjacent to the third cut, which is made on second side
edge of the strip and extends in a direction towards the opposite first side
edge, the total length of the third cut and the forth cut added together falls
between once and twice of the width of the strip and are not in aligned with
each other but slightly spaced apart in order to create a tiny strip of
conducting path. Optionally, more cuts of the same length that each extends
more than half of the width of the strip also can be involved.
This technique of controlling the electrical
resistance of a strip in the current invention is extremely useful in some
application especially when there is batch variance in quality in the
electrical property of the incoming static dissipative batch material where
such material need to be converted in finished goods in strip forms for use in
various commercial applications including those cited in some of the subsequent
paragraphs below.
The invention disclosed helps to minimise rejects
due to out-of-spec high conductivity which is relatively common in ESD material
compounding in the ESD products manufacturing industry particularly the mixing
of the electrically conductive carbon powder onto a rubber or polymer system.
The invention helps to correct the electrical resistance in a finished strip by
such cutting technique to improve product quality or minimise rejects.
Figure 5 is a structure diagram of an adhesive tape
of conductive/static dissipative properties according to an embodiment of the
present invention. Refering to Figure 5, when the invented conductive strip
sticks onto a normal adhesive tape of bigger size as shown in Figure 6, the
tape becomes a conductive tape with a more precision controlled electrical
resistance from one point to another.
Figure 6 is a structure diagram of a shoe sole of
conductive/static dissipative properties according to an embodiment of the
present invention. Refering to Figure 6, the invented conductive strip will
find good use in making conductive shoes by incorporating such strip through
threading process into the shoe sole as shown in Figure 6 to achieve a one to
two mega ohms body-to-ground electrical resistance with high commercial
attractiveness.In particular, the strip is wrapped with an adhesive tape with
reinforced sewn line and embedded into a small slit made on the normal shoe
sole.
Figure 7 is a structure diagram of a mounting pad
of conductive/static dissipative properties according to an embodiment of the
present invention. Refering to Figure 7, a mounting pad of conductive/static
dissipative properties comprises a conductive top layer 710 with a conductive
property of 10e4 to 10e5 ohms, an insulative bottom layer 720, and one or more
mounting bands 730 that comprise a strip described above. When the invented
conductive strip is threaded through a specially designed two-layer conductive
mounting pad with more conductive property say 10e4 to 10e5 ohms on the top
layer and insulative property at the bottom layer as shown in Figure 7, it
provides a more precisely control of body-to-ground resistance to achieve a
better control of body voltage with adequate safety electrical resistance
margin in the management of ESD in a typical ESD-sensitive work environment.
Typically a one to two mega ohms is readily achieved with such simple
'two-cuts' or 'multiple-cuts' technique in the current invention. Accordingly,
w hen incorperating the conductive strip as a mounting pad on an ESD chair as
shown in figure 7, it achieve a simple economic way to effectively convert a
normal chair seat to to an ESD groundable chair seat.
The invention is unique as all prior arts cited in
the background of the invention are more sophisticated than the current
invention leading to higher cost of manufacturing and other limitations in
commercial attractiveness in numerous applications. When implementing present
strip with segments of conductive/static dissipative properties and its
applications, following advantageous effects will be obtained: the precise
control of the electrical resistance between two edges of the conductive strip
is achieved by varying the space gap between the cuts or varying the length of
the cuts, without the need of doing any additional design or additional work.
Accordingly, the invention is operable to control the electrical resistance of
a strip with good accuracyin a simple and cheap way, so as to effectively drain
static charge from body to ground readily and safely.
