PCB medical is also known as medical printed circuit boards. They are a very important aspect of electronic components. A lot of people make use of them every day without really paying attention to them. However, they are actually quite critical to a vast array of industries. Printed circuit boards have a lot of applications. In this write-up, we are going to discuss a few of the common ones.
What Is a Printed Circuit Board Used for?
PCBs put simply, are boards that connect electronic components together. They are manufactured using a non-conductive material. Copper sheets are used to form lines and pads on the material. These lines connect the electrical components in a product together. You will often find components like resistors and capacitors soldered onto PCBs also.
In the present day, there are all kinds of PCBs being used in electronic products. Some of the types commonly used include single-sided, double-sided and multi-layer PCBs. These PCBs can be made either rigid or flexible, and sometimes both styles are implemented on a single PCB. The electronics made from PCBs play a huge role in our daily life. They make possible importance products like smartphones, computers and kitchen appliances.
Light-emitting diodes are also known as LEDs. They are a technology used for illuminating residential and commercial buildings. They are also used in various Industries like the computer technology industry, the medical industry and the automotive industry. They grow increasingly popular by the day. This is because of their long life, energy efficiency and compactness. One of the key roles of PCBs in LEDs is that it helps to transfer heat away from the bulb. Without the PCB, the temperature of an LED would run high and this would decrease its average life.
Uses of printed circuit boards in the Industrial sector vary vastly. Most of the equipment in manufacturing and distribution centers are powered by electronic components. They also power equipment in other industrial facilities. High-powered PCBs are required in the Industrial sector. These PCBs also need to be very durable. This is because they are likely to withstand a lot of harsh conditions in industrial facilities.
The amount of electronic components required by automotive manufacturers for their vehicles is on the rise. Before now, PCBs were only implemented in car parts like headlight switches and windshield wipers. Today, they are used to implement many safety and ease functionalities. The PCB may require resistance against extreme temperatures and vibrations. This depends mainly on the parts of the car that they will be used in.
A wide array of PCBs is used in the telecom industry. This is because a whole lot of equipment are used in the industry. The type of PCB use in certain equipment is determined by the environment that the equipment will be used in. Some equipments are used indoors while others are outdoors where they have to withstand storms and harsh temperatures.
The healthcare sector is another sector that has a growing need for PCBs. The technology has improved the sector and created a whole lot of possibilities in it. PCBs can be found in devices used for treatment, monitoring, diagnostics, etc.
When it comes to producing medical PCBs, special attention is required to ensure reliability. This is because human lives depend on the devices they are put in. PCBs also have to meet very strict standards when it comes to sanitation. This is especially true for the ones used in implants. First, they have to be clean. They also have to be smaller than usual. For this reason, most PCBs used in medical devices are HDI (High-density interconnect).
You will find PCBs in medical devices like:
1. Medical imaging systems: PCBs are always in ultrasonic, CAT and CT scanners. The computers that compile and analyze the images taken by these scanners also makes use of PCBs.
2. Monitors: Devices used to monitor blood pressure, heart rate and blood glucose all make use of PCBs to ensure that accurate reading is always obtained.
3. Infusion pumps: Pumps like the ones used to infuse insulin and analgesia into patients require precision when delivering fluid. PCBs are employed to ensure the required precision and reliability.
4. Internal devices: Devices that are inserted into the body, like pacemakers often make use of PCBs to function.
5. Smartphones, iPads and Tablets are now replacing traditional methods of monitoring and recording. Patients today, have the option of conducting a thorough discussion with a medical professional from home.
The market for medical devices that individuals can wear is growing at a rate of 16.4 percent a year. The collection of information is realized by using sensors and medical apparatuses that can be effortlessly worn by individuals. One aim of the healthcare industry is to collect as much data as possible. Wearables can do very beneficial things like let someone know if their aged family member or patient has slipped and fallen. It can also inform you if someone’s about to catch an infection from a cut.
The need for electronics in the medical sector continues to grow daily. The manufacturing industry continues to successfully reduce the size and increase the density of PCBs. This will enable the role of PCBs in healthcare to continue to grow.
Most Commonly Used Materials Used In Manufacturing Medical PCBs
The circuits are made with a thin coat of conducting material. They are placed, or “printed,” on the top of an insulating panel known as the substrate. Each electronic component is placed on the surface of the substrate and joined with the interconnecting circuits. Contact bits along one or more edges of the substrate work as connectors to other PCBs or to external electrical devices like on-off switches. A medical printed circuit board could have circuits that execute only one function. An example is a signal amplifier. It could also have several functions.
There are three foremost types of printed circuit board assembly: single-sided, double-sided, and multi-layered. Single-sided boards have the modules on one side of the substrate. Sometimes, the quantity of components becomes too much for a single-sided board. That’s when a double-sided board can be used. Electrical networks between the circuits for each side are made by boring holes through the substrate. The holes must be bored in the proper locations. Next would be plating the inside of the holes using a conducting material. The third kind is a many-sided panel. It has a substrate made up of sheets of printed circuits parted by layers of insulation. The modules on the surface are joined through plated holes bored down to the correct circuit layer. This significantly streamlines the circuit configuration.
Glass fiber reinforced (fiberglass) epoxy resin is the most often used substrate in medical PCBs. It usually has a copper foil bonded to one or both of its sides. Generally, medical PCBs have printed circuits made of copper. The circuit is either etched away or plated on the surface of the substrate, using any desired pattern.
To prevent oxidation, the circuits are usually coated with a mixture of tin and lead. The contact fingers are first coated with the tin and lead mixture. Then, they are coated with nickel, and lastly with gold to ensure great conductivity.

Streamline Qualification with Your Medical PCB Manufacturer
The amount of impact that a PCB can have on a human, especially as a medical patient, is truly amazing. From laser eye correction equipment to heart monitor to X-ray imaging system, PCBs are employed to serve multiple functions. PCBs, give these bunch of electronic components and wires the ability to save a life.
However, it’s not just about producing state-of-the-art medical equipment. You have to make sure that these devices are accurate, reliable and of topnotch quality. Once you are done with design and are ready to move to manufacture, you are ready to move on. The next step to take would be finding a contract medical PCB manufacturer that meets all the quality and reliability standards. You will need to find someone that can manufacture high-quality products at very low costs.
International Organization for Standardization (ISO) certifications is a critically important certification for medical equipment manufacturers to have. In the ISO 9000 series of quality standards, quality and reliability requirements as regards design, manufacturing, and testing in various industries, are fully specified. Be sure to look out for manufacturers that have taken the effort to obtain and maintain at least one ISO 9000 certification.
You must look out for manufacturers that take traceability into consideration. The manufacturer you pick should be one that documents and monitors the use of all the PCBs they have manufactured. This eases the process of pulling back an affected product in the case of a recall. If your manufacturer is ISO 13485 certified, they will be aware of all recall procedures for medical devices. They will also already have systems in place to ensure full compliance with relevant regulations.
Ensure that the medical PCB manufacturer you choose meets some required criteria. Criteria like having the knowledge and expertise required in identifying manufacturing problems, evaluating the cost of materials, and optimizing the entire production and assembling process. An experienced manufacturer would be able to simplify the circuit designs and help you reduce costs. A seasoned manufacturer would take EOL components into account when planning. Parts shortages should be accounted for, manufacturability should be enhanced and strict quality standards should be maintained.
A good manufacturer will help you streamline the testing and inspection processes of your medical PCBs. This would go on to suppress long-term risk for you. They should be willing to meet regularly with you, to discuss manufacturing and assembling progress. Ultimately, what you need are very high quality and very low cost.
