Medical Device PCBA

Medical Device PCBA

Medical PCBA is a circuit board used in medical equipment, which is widely used in medical lighting, ultrasound detection, physiological monitoring and other fields. The electronic components used in medical equipment have high safety and reliability standards because they involve human health, medical safety and other fields.


PCBAs are at the heart of these medical devices. PCBAs in the medical industry are highly specialized to accommodate the unique constraints of medical devices. Therefore, medical PCBs are often special high-density interconnect PCB (HDI) PCBs. Medical PCBs can also be made from flexible substrates that allow the PCB to flex during use, which is essential for both internal and external medical devices.

Medical Device PCB Types

(1)Flexible PCB: Flexible PCB is the preferred choice for many medical devices. Since medical devices are often placed where flexibility is required, the malleability of flex PCBs makes them a good choice. Turn to flexible PCBs when medical devices will be folded and wrapped.


(2)Flexible Aluminum PCB: While flexible PBCs are suitable for many electronic medical devices, some high-power devices require more robust PCBs. Flex Aluminum PCBs are ideal for high power applications due to their heat transfer properties. Some major applications for these boards include scanning and surgical lighting applications.


(3)HDI PCB: Another factor you may want to consider is whether you are going to use flex pcb microcircuits. Like flex PCBs, PCB microcircuits are malleable, but they separate themselves by allowing you to use smaller PCBs with higher performance. Due to their design, PCB microcircuits are often used in small medical devices such as industrial sensors, wearable technology and hearing aids.


(4)Polyimide PCB Material: Polyimide is often a good choice when you are looking for a suitable substrate for your PCB. Polyimide PCB material has excellent tensile strength and flexibility. These materials are also very durable, very thermally stable and chemically resistant, making them ideal for certain medical devices such as prosthetics and implants.


(5)Ceramic PCBs: Ceramic PCBs are an excellent choice for organizations using medical devices with circuits that have a low coefficient of thermal expansion and high thermal conductivity. These PCBs can operate at extremely high temperatures, provide incredible high frequency performance, easily achieve high density tracking and provide strong chemical resistance.


(6)Rigid-flex PCB: Rigid-flex PCB combines the advantages of flexible circuits with the durability of rigid PCBs. The flexible material sits between rigid layers with conductors and is plated with vias to connect them to other layers. These boards are more durable than flex boards, without the weight and size of rigid boards, presenting more design versatility. They are common in consumer electronics, lighting, contract manufacturing, instrumentation, and other applications.



Medical Device PCB Assembly Focus

Reliability in medical PCB applications is critical, whether used in the operating room or in the laboratory. The medical field has no place for equipment failing or not functioning properly. The following medical device PCB assembly focus:


  • PCB design should consider the specific requirements of the medical device, including component count, board size, and thermal management requirements.
  • Components must be placed carefully and routed correctly to ensure a successful board.
  • Component selection is critical to making reliable medical devices. It is important to find the best components that meet the specific requirements of a medical device, are reliable, durable and have a long service life.
  • Choose a reputable medical PCB assembly factory or a PCBA processing factory with experience in serving the medical industry. Make sure they can make high quality boards.
  • Using lead-free PCB assembly is considered an effective practice, and choosing a company committed to sustainability can have unexpected benefits for your project.
  • PCB cleaning process is especially important in the field of medical electronics. While the purpose of cleaning is usually to avoid short circuits caused by surface contamination during use, in medical equipment, residual cleaning agents can cause harm to patients.
  • Assembled circuit boards must be thoroughly inspected and tested to ensure they meet the required standards for reliability, performance and safety.

To ensure that electromagnetic interference (EMI) does not affect medical PCBs, engineers should refer to various EMI standards.


How to control the quality in Medical Device PCBA Service?

With the continuous development of medical science and technology, all kinds of electronic medical equipment are constantly emerging on the market, and the demand for the use of various circuit boards is also increasing; among them, SMT chip processing is a high-precision Technology, so medical electronic SMT patch processing should pay attention to the following issues. In the process of medical electronic SMT patch processing, medical electronic products have their special requirements. Whether it is medical testing equipment or medical auxiliary tools and equipment, a high utilization rate is required, and high stability is very important. Considering the special requirements of medical equipment, the quality control of patch processing must be strengthened.


①Quality control of components: In the quality control of medical electronic components, quality control must be carried out from the source of procurement. After the purchase is completed, the components need to be inspected, sealed and stored, and the special BGA and IC must be stored in a moisture-proof cabinet.


②Solder paste control: In the patch processing of medical electronic products, solder paste must be selected and stored according to product characteristics. During the construction process, the mixing and addition of flux must be strictly controlled.


③ Solder joint control: After the components and solder paste are fully qualified, the solder joint control determines the quality of SMT chip processing. In short, the quality of solder joints determines the quality of chip processing.


④Static control: static discharge can reach several thousand/w. Damage to BGA and IC components is invisible and latent. Medical electronic equipment needs to process a large amount of data in its application. If the core components are damaged by static electricity, the decrease in stability will affect the stability of the product.


Medical PCB Manufacturing and Assembly


Medical PCB Manufacturing

In the medical PCB manufacturing process, the customer first sends the Gerber file, and our engineers evaluate and make EQ and working Gerber. Then start feeding production.


Then the inner layer is printed copper--combining different layers (pressing)--Medical PCB Outer imaging--Outer etching--Solder Mask--Silkscreen--Surface finishing.


Medical PCB Assembly

PCB assembly is the key to product molding. So the quality of PCB is very important. When assembling medical PCBs, we cannot release any error in any part. We must be careful, rigorous, and check carefully to ensure that it is correct. The following is the Assembly process of medical PCB:


PCB board preparation, Solder Paste Stencil Printing, component installation, reflow soldering, testing, packaging and delivery.

Medical PCBs often feature a mix of through-hole and surface-mount components, which increases production costs. As medical devices such as wearables become more compact, PCB assembly becomes one of the most challenging aspects of manufacturing. This is where a turnkey PCBA company can play a key role. Using autoclavable or washable components can help reduce the cost of medical PCB assembly.
