The change in medical technology has lead to a revolution in the domain of coil winding technology. The growth of the micro-sensors has ensured that micro-coils get manufactured at an industrial level. There are many challenges that the micro-coil winding generally faces. Yet, this article will explore the ways in which micro-coil winding takes place.
The winding is done in such a way that the wires stay separated from each other. The wires are spiraled around a core to create an electro-magnetic effect. There is a stark difference between the shapes and sizes of the various coils.
Some of the most common shapes include:
It is very important to note that any change in the outer and inner dimensions of the wire can bring change in the conductivity properties of the wire.
Bottlenecks in micro-coil manufacturing
Understanding that the micro-coils are used for medical applications that require very thin wire is crucial. It makes the manufacturing of such coils a manufacturing challenge. The coils are to be manufactured using highly precise machinery.
More often than not, the machinery needs to be developed from scratch to deliver such excellent results. The insulated copper is generally wound around a core. The coil can be core-less or wound in the shape of a rectangle too.
Wounding it around a rectangle and then removing it to form a rectangular shape of the coil is generally done.
One of the major bottlenecks in preparing the coil is the size of the coil. The micro-coil is very thin in size, which makes it difficult to be manufactured. The coil is even thinner than a human hair. For such reasons, it is not easy for winding the micro-coils.
Need for a micro-coil winding machine
A micro-coil winding machine just doesn’t exist in the market. In order to make the windings, the machines need to be manufactured in house. Since the size of the coils is so thin, the machines need to be manufactured as per the requirement of the clients. There can be issues regarding handling the wires which are thinner than the size of the hair. It can lead to change or variation in the properties which can hamper the device.
The device which is used for the manufacturing of the coils is built such that they provide precision. Not many manufacturers can build such machines. With the dynamism in the coil winding technology, it becomes difficult for the organizations to adapt to the change.
Changing times call for changing methods
Micro-coil windings require the use of the machinery which is not already available in the market. It is the major reason why such types of machinery are to be built in the first place. Various shapes of the micro-coil ensure a wide application of the same. The specification of the material is such that they have to be resistant to heat and temperature. The ability to tolerate the reverse breakdown voltage needs to be high, such that the micro-coil can perform efficiently.
