Medical PCB: What Does This Mean?
It is clear that the medical field is the most sensitive, and by a large margin. This is because they deal majorly with the lives of humans. The sensitivity of this field means that the facilities, as well as equipment used here must possess some characteristics, with the most important of all being precision.
These PCBs are printed circuit boards specifically designed to help make medical facilities and equipment. Therefore, they are specialized for different care and lab settings and different testing scenarios.
Some medical machines and equipment made with these PCBs include heart monitors, blood glucose monitors, blood pressure monitors, heart pacemakers, OEM medical devices, and more.
Medical PCB: Types
Medical PCBs are available in many types in the market. Here are some of the most common.
This type of medical PCB is made from just one layer of base material or substrate. One of the sides of the base material is coated by a thin metal layer, especially copper.
Most times, they come with a solder mask that is applied on the copper layer’s top. 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.
This type of PCB features a conductive layer made of metal on any of the substrate’s phases. Through the board’s holes, you can attach the metal parts on the sides. Through hole technology, connection of both sides is possible.
Through the circuit board’s pre-drilled holes, the component leads are fitted in. Next, they are soldered to the opposite sides’ pads.
These 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.
This type is made up of three or more copper layers. They include 8L, 6L, and 4L pcb. The “L” here stands for the layers. Here, insulating materials and substrate boars are used in demarcating these layers. This type has a great benefit of space and heaviness. They are also very useful when making circuits of high speed.
With their size, they can also give more room for conductor power and pattern. Generally, they enable flexibility of design. Medically, they are very useful in very sophisticated equipment and machines, which perform large tasks and require speed.
These PCBs are utilized in devices for medical testing, heart monitors, CAT scan equipment, and today’s X-ray equipment.
This type of medical PCB is manufactured from materials that are nonflexible. Therefore, you cannot bend their bases. This means that you can craft multifaceted circuitry from them. It is also easy to preserve them.
These are majorly utilized in medical equipment with rigorous functions such as some devices for medical testing.
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. Asides from this, they are utilized in areas where density and temperature are a big concern.
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.
Medical PCB: Benefits
As mentioned earlier, medical PCBs are utilized in manufacturing equipment and electronic devices utilized in medicine. Regarding this, these equipment and devices have brought some benefits to the medical sector in these ways:
For long, the medical service delivery experienced slowness due to lack of integration. Some patients gave up the ghost because it took a long time to transfer their records between different sections.
However, in the past few decades, there has been great improvement in patient care. This is possible, thanks to the PCB technology utilized. Presently, there is now speed and efficiency in service delivery as a result of the easy and quick flow of info.
The design of drugs usually happens based on data gathered on a specific population. This technology has ensured that this data is gathered easily and better. It has also ensured the quick development of these medicines.
Presently, smartphones and IPads have ensured that medical specialists receive as well as transmit information freely. Also, ordering of drugs has become easy. This is very important for medical research and documentation.
We have systems that convey secure information and alerts like laboratory tests. Most times, they utilize clinically-based systems, web applications, or smartphones.
This improvement is great, considering how difficult it used to be to pass information. Also, you can easily see hospital staff making use of walkie-talkies and instant messaging applications. This dissociation from using overhead PA systems and pagers is a positive one.
All these are happening due to how advanced PCBs have developed. These developments have made it possible for the communication systems of the health sector to be refined.
Now, there are medical devices that can be worn to help in monitoring patient’s information. Football players put on “bras” that have trackers, which help in checking the heart rate of players. Being able to track this information, makes it possible for medical specialists to know whenever a patient has been attacked or is infected.
Prototypes of Medical PCB
Medical PCB prototypes are vital in the early stages of the design process in order to test the functions of any PCB solution. This prototype undergoes many runs, to help in testing the redesigns. At times, the test is run just for one function, and after this, it is used in constructing very complex designs.
Prototyping medical PCBs therefore help the designers to predict success, as well as mitigate failure. Therefore, this helps in getting rid of losses, which can occur as a result of detecting these problems late.
Full manufacturing of the PCB should only take place when the engineers are sure that the prototype successfully meets the necessary standards. To achieve the best results, the process of prototyping usually goes through these steps:
- Have a proper PCB description
- Design your PCB
- Conduct schematic design
- Create a Bill of Materials
- Prepare a unique routing design
- Build your photo film
- Print its inner layers
- Fuse these layers
- Drill holes
- Do the copper plating
- Imaging of the outer layer
- Plate the tin and copper layer
- Final etching
- Application of solder mask
- Surface finishing
- Apply silkscreen
- Do the cutting
