PCBs will play an increasingly important role in healthcare. At the heart of these medical devices are PCBs. The medical sector is continually coming up with more uses for electronics. Medical PCBs are used in the cardiovascular field, for heart-related applications, like pacemakers. Medical PCBs used in medical imaging applications, like in MRIs. Medical PCBs found in monitoring devices and gadgets such as body temperature monitors , pulse oximeter(used in our front office). The market for medical devices is growing at a rate of 16.4 percent in a year.
Medical devices that use PCBs
1. Medical imaging systems: PCBs are always in ultrasonic sensor, CT scanners Computed tomography (CT) can produce detailed images of many structures inside the body, including the internal organs, blood vessels and bones. 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 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. Smart phones, I Pads, 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.
Find types of PCB in medical devices like
1. Single layer PCBs are usually preferred due to their very low cost of production. Medically, they are utilized in simple circuits such as power sensors.
2. Double layer PCBs can be utilized in so many areas in medicine. These include devices for communication such as walkie-talkie, as well as some equipment for medical testing.
3. Multi-layer PCBs can be utilized in devices for medical testing, heart monitors, CAT scan equipment, and today’s X-ray equipment.
4. Flexible PCBs This type has a flexible base material. This medical PCB can either be multi, double, or single sided. Due to their flexibility, this makes them great for saving space. They also do great in reducing the overall weight of the board. they are utilized in areas where density and temperature are a big concern.
5. Rigid-Flex-PCBs This type of PCB helps in combining the features of flexible and rigid PCBs. The major benefit of the rigid-flex pcb is that they only use limited space and are lightweight. They can also be applied in different areas of medicine. One of these is the handheld device used in medical care communication.
6. High-Frequency PCBs medical devices that can be help in monitoring patient’s information. Players/patients put on bras/watches that have trackers, which help in checking the heart rate information, makes it possible for medical specialists to know whenever a patient/players has been attacked or is infected. tracking information is passed via GSM/GPS VIA RADIO FREQUENCY PCB(Antenna has been fixed as track line in pcb)
HDI / Via-in-Pad:
This technology allows us to reduce the footprint of the in Medical PCB.
Glass fiber reinforced (fiberglass) epoxy resin is the most often used substrate in medical PCBs
High density interconnect or HDI technology enables circuit boards to be made smaller with more complex routing in medical PCB.
High Density Interconnect (HDI) PCBA Applications in Common Medical Devices
