Medical PCB Assembly: A Comprehensive Production and Service Guide
Did you know the global healthcare industry is worth nearly $12 trillion? As time passes, businesses will reinvest a large portion of this value in medical technology.
Medical printed circuit boards (PCBs) are one of the most notable pieces of industry tech, but only some understand how they work or how the manufacturing process works.
Let’s take a look at everything about medical PCB assembly.
What is the Role of a Medical Printed Circuit Board?
One common use is to provide electrical signals between different parts of the device its attached to.
For example, in a pacemaker, PCBs help to send electrical signals from the battery to the heart.
Another use for PCBs in medical devices is for data storage and processing. Similarly to a computed tomography (CT) machine, PCBs store data about the patient and then process that data to create images of the inside of the body.
You can also use PCBs to provide structural support for other device parts. This is especially common in larger medical devices, such as X-ray machines.
What are the Challenges of Medical PCB Assembly?
One of the biggest challenges in medical PCB assembly is miniaturization. As technology advances, medical devices are becoming smaller and smaller.
The first step in medical PCB assembly is designing the device itself. The designer creates a layout for the PCB that includes all of the necessary features. Once the design is complete, it is sent to a manufacturer.
When assembling the PCB into a medical device, there are several options. The most common is to use surface-mount technology (SMT). This involves placing components onto the PCB and then soldering them into place.
Another option is to use through-hole technology (THT), which requires drilling holes into the PCB and soldering components. Mixed assembly is also possible, which combines both of the above methods.
Once all the components are in place, the PCB must undergo testing to ensure that it functions correctly.
In context, the entire process follows this path:
- Component placement
- Soldering
- Washing
- Testing
- Coating
- Mechanical
- Packing
Due to the complexity, you must work with the proper professional assembler.
What are the Steps in Medical PCB Assembly?
At Geospace, the first step in an assembly process is reviewing the PCB design, and a manufacturability test or DFM check is conducted to check for any last-minute issues.
Once the design is cleared from review, the assembly team moves on to an eight-step process.
- Surface Mount Technology (SMT)
- Component Place and Inspection (PTH)
- Hand or Wave Soldering
- Washing
- Test
- Coat
- Mechanical
- Packing
Our team also always works with you to follow the specifications you need for your products while also making the process cost-effective.
How Can I Improve the Assembly Process?
There are a few things that you can do to improve the medical PCB assembly process. First, it is essential to work with a reputable professional. This is the only way to ensure that your PCBs meet the necessary standards and requirements.
You should test your PCBs thoroughly after they have been assembled. This will help to catch any issues that may have arisen during the assembly process.
It’s essential to note that a reputable assembler will also test the PCB before assembly begins so that they can provide further support and review of the PCB designs. Not only will this help streamline assembly, but it will also catch problems before they arise.
What Should I Look For in Medical PCB Assembly Services?
It should come as no surprise that there are a few things that you should look for in medical PCB assembly services.
First and foremost, you should ensure that your chosen manufacturer is experienced and reputable.
It would help if you also asked for quotes from multiple manufacturers before deciding. This will help ensure that you get the best possible price for your PCBs.
It’s also essential to ask for samples of the manufacturer’s work. If you are happy with the quality of their workmanship, you can move forward.
Working with a manufacturer that holds multiple certifications is also recommended. Be sure to consider whether or not the manufacturer is certified in the following:
- ISO 9001
- ISO 14001 (environmental)
- ISO13485 (medical)
- AS9100 (aerospace)
Lastly, see what other people say about working with the professional in question. Remember, though, only some feedback you encounter will be genuine. Understanding how to recognize fake reviews can go a long way when looking for someone to work with.
By taking these steps, you can be sure that you are choosing the best possible manufacturer for your medical PCB assembly needs.
Medical PCB Assembly Doesn’t Have to Be Difficult
