How Crucial are Cable Assemblies for Medical & Healthcare Sector?

Cable Assemblies are widely used in precision medical device applications in hospitals, clinics, labs, and medical facilities. They connect medical equipment that is widely used for patient monitoring and treatment. Keeping in view the critical aspects associated with the healthcare sector, failure of medical devices due to wire harness and cable assembly manufacturing defect can never be on the list of options.

Regulatory Standards for Cable Assemblies in Medical Devices

Medical facilities are held to high regulatory standards since they are more often than not subjected to high temperatures, tension, and abrasion. When cable assemblies and wire harnesses are manufactured, a primary factor is to have increased wear and tear. Based on the assembly specifications that includes cable type, conductor range, plating, shielding, insulation, and material used, cable and wire harnesses need to withstand high temperatures, tensions, and chemical sterilization procedures to maintain high regulatory standards.

Uses of Cable Assemblies and Wire Harness in Medical Sector

In the medical and healthcare sector, cable assemblies are widely used in medical devices ranging from patient monitoring systems, ultrasound equipment, therapeutic devices, electric catheters, fetal monitors, to lab analysis equipment, heart rate monitors, defibrillators, and ECG machines. Let us take the example of a cardio meter that is hooked up to a heart patient. The patient will be healthy and alive when the patient’s heart rate is within a certain range. Cable assemblies play a significant role in monitoring this range. Moreover, they are connected to the computer device that collects data and reports the patient’s heart beats from which doctors keep a track of the patient’s progress.

Sterilization Techniques of Cable Assemblies for Medical Devices

To eliminate biological agents such as bacteria, viruses, etc. sterilization techniques are employed. The manufacturers of medical cable assemblies can use a few techniques to ensure complete sterilization since this requirement is critical. Some of the important sterilization techniques for medical devices are discussed as follows:

Steam Heat Sterilization

Steam heat is like a pressure cooker in which steam under pressure acts as the sterilization agent. The heat reaches up to temperatures as high as 134 degrees Celsius and last up to 20 minutes depending upon the load necessary.

Dry Heat Sterilization

Dry heat is like a conventional oven and the foremost choice among sterilization techniques. Giant ovens are employed in which heat up to 160 to 170 degrees Celsius for durations of about 1 to 2 hours is subjected to the cable assemblies.

Radiation Sterilization

This method employs either gamma rays or an electron beam to sterilize the application. This sterilization setup is similar to a microwave and it sterilizes all the components of the device at the same time.

Ethylene Oxide Sterilization

This is a chemical sterilization process in which Ethylene Oxide commonly called EO is employed. If the application cannot be exposed to high temperatures and moisture, this method of sterilization comes out to be a better one. It can also penetrate the packaging and products to kill the microorganisms.

Each of these sterilization techniques ensures complete sterilization. The choice of any one of them depends upon the specific limitations and requirements of your medical device application.


Medical and healthcare is one such sector where there is no option for failure as it can threaten someone’s life. Since medical devices widely use cable assemblies, it necessitates the use of best in class cables and wires in the equipment. Manufacturing cable assemblies and wire harnesses must, therefore, be done in an infallible manner with the help of professional electronic manufacturing service providers.

Industrial Electronics from the Perspective of PCB Assembly Services

Change is the only constant. The industrial electronics market is no different from this fact. With the impressive growth of the industrial electronics, the use of advanced circuits and processes has become a necessity. And these advanced circuits make use of advanced PCBs. The requirements associated with industrial electronic applications are diverse and complicated, and so the PCBs are designed by the Printed Circuit Board Assembly Manufacturers keeping these intricacies in mind. Not only these PCBs are designed to withstand extreme environmental conditions, they have anti-corrosion properties as well.

PCB Performance in Extreme Conditions

Industries basically employ high-powered applications. These applications demand PCBs that are robust and have high performance. There are several key components that make up these PCBs. They facilitate controlling and operating various mechanisms utilized in manufacturing units and factories. Every industrial process is characterized with long working hours, additional stress, and adverse environmental conditions. The components of the PCBs must be capable of handling these unfriendly conditions. If we take a closer look, every industry has one or the other type of conditions that can be a test for the PCB and its components. Chemical industries pose the threat of exposure to potentially harmful chemicals, manufacturing industries might give rise to conditions such as rough handling, or machinery in which there is a lot of vibration, etc.

Applications of PCB Assemblies in Industrial Electronics

The rapidly changing industrial environment has challenging implications for PCB assembly and manufacturing. Keeping this in mind, companies use PCBs that are suitable for high current applications, for instance thick copper PCBs.

In power control devices, PCBs are used in devices such as DC to AC power inverters used in the solar energy sector. Apart from this, PCBs also find their use in measuring equipment that measure and control several variables like temperature, pressure, etc. Manufacturing industries also make heavy use of PCBs for drilling and presses.

The list of industrial electronics applications that employ PCBs is almost unending. From power monitoring, visual signaling devices, thermostats and transformers to digital meters, fuses, LED lighting and oscilloscopes, high performance PCBs form a key component to meet the demands expected from these applications in their respective industries.

Professional PCB Assembly and Manufacturing Services for Industrial Electronics

To procure PCB assemblies for industrial electronics, it is always advisable to source PCB assemblies from an expert. A professional partner with extensive experience in designing and building PCB assemblies for several industrial electronics applications will make your investment worthwhile.

Apart from that, the right PCB assembly partner guarantees compliance with supply line oversight. Implementing per component tracking, your PCB assembly partner will work closely to do everything possible to keep the supply line clean, and with data to support it.

As already mentioned, the industrial electronics sector has complexities of its own, and it is quite a natural fact that newbies can never provide the same quality of service that companies with years and decades of experience can. Most of the times, it is not just about the engineering, manufacturing or assembling skills, it’s about showcasing human qualities to make contracts and develop networks with trusted vendors. And that comes only with experience.
