Thermocompression bonding is one of the most critical aspects when it comes to the medical coil industry. It is a completely new method which has been discovered in order to ensure that the efficiency is improved for the medical coils. Thermocompression bonding provides a lot of improvement over the traditional soldering method which makes it stand out. The traditional soldering method comes with numerous challenges that impact the quality of the medical coil as well as destroy the chemical composition. In this article, we are going to discuss a little bit more about thermo-compression, bonding and the advantages that it provides over the traditional methods. 

Medical coil winding is a highly precise domain wherein special care needs to be taken to get the right product. Safety is of the highest concern and in such a situation it is very much critical for each and every medical practitioner to pay attention to it. Manufacturers of medical devices have moved on to thermo-compression bonding as it offers extensive benefits. 

Disadvantage Of Soldering

The disadvantages of the traditional soldering method are as follows: 

  1. The soldering takes place at a very high temperature, which is very critical for the metal wires. High temperatures often bring about a change in the physical and chemical properties of the wire. 
  2. The change in the chemical properties of the wire brings about an alteration in the expected behaviour of the medical device. It can often result in a change in the electromagnetic induction and conductance properties, resulting in malfunctioning of the device. 
  3. Soldering can often be the source of impurities within the medical device. As medical devices are going to be implanted within the human body, any such form of impurities are not expected. In fact, these impurities can result in a lot of damage to the reputation of the organisation, too. 

These three critical factors have resulted in the medical device industry moving forward to thermal compression bonding. 

Thermocompression bonding takes place at a very high pressure wherein the wires which are of similar diameter or length are joined with each other. 

Understanding Thermo-Compression Bonding 

Thermocompression bonding is a process that allows the thinnest wires to be connected to wires which are of similar diameter or are made of different materials. 

The wires can be connected to a thickness of as high as 12 times more compared to the other one. 

Traditionally, the wires were connected either by welding or soldering method, but thermo-compression bonding has given a better alternative to the traditional methods. In today’s world, the increasing demand for miniaturised devices has resulted in the growth of microcoil medical devices. Microcoil winding is thus becoming a very critical component within the medical device industry. 

However, joining ultra thin wires is one of the most important challenges that cannot be neglected, especially when the expected shape and size of the medical device is very small. The smaller the size of the medical device, the higher are the external constraints and environmental factors which impact the performance of the medical device. Thus traditional methods cannot be used and thermocompression bonding takes its place. 

Advantages Of Thermocompression Bonding 

Thermocompression bonding has reduced noise levels which improves the efficiency of the medical devices. It’s a far safer production process, thus reducing the risk of damaging any sensitive components. The highly reliable connections with negligible oxidation and the lower production costs make them very suitable for bulk production as well. The robust and automated manufacturing process reduces any form of human error, thus improving their performance and output levels.
