Main steps to assemble a medical PCB
PCB manufacturing and preparation
Manufacture bare board PCBs according to design specifications, including etching, copper plating, drilling, and addition of solder masks. This stage ensures that the layout of the board meets the requirements of the circuit diagram and that the structure is robust.
Solder paste
Apply solder paste to specific areas of the board using a template to facilitate subsequent welding of surface mount components (SMDs). The application of solder paste must be accurate to avoid problems with bridging or insufficient solder paste, which can lead to poor connections.
Component mounting
Use an automatic mounter to place surface mount components (SMDs) onto the PCB. The machine can precisely position each component. In some cases, precision or sensitive components are manually mounted to ensure accuracy and prevent damage.
Reflow soldering
After the component is mounted, the PCB is heated by a reflow furnace to melt and solidify the solder paste to form a strong connection. The temperature curve is precisely controlled to avoid thermal damage to the sensitive element.
Through hole components soldering
For components that require stronger mechanical connections, such as connectors or large capacitors, use through-hole technology. Components are inserted into pre-drilled holes and fixed to the circuit board by wave soldering or hand soldering.
Clean
After soldering, clean the assembled circuit board to remove flux residue and other contaminants and ensure that no conductive residue remains on the board. In medical PCBA manufacturing, the cleaning step is critical to meet sterilization and cleanliness standards.
Protective coating or potting (if necessary)
The circuit board may be coated with a protective coating to shield it from moisture, dust, and other contaminants. Potting (encapsulation of the circuit board in a protective resin) is used in some critical applications to ensure durability and reliability, especially in harsh medical environments.
Final assembly and marking
Integrate the PCBA with other mechanical components of the device and mark compliance, including bar codes or serial numbers, for easy traceability to comply with regulatory requirements for medical devices.
ISO 13485: Quality Management These standards are dedicated to establishing quality control for PCB medical device production.
IEC 60601: Electrical safety and performance This standard outlines the requirements for electrical safety and performance. It ensures that medical PCBs comply with safety regulations, protecting patients and staff from hazardous radiation.
RoHS and REACH Compliance: Environmental Responsibility RoHS(Restriction of Hazardous Substances Compliance) prohibits the use of hazardous substances in PCBs. REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals Compliance) was drafted with the intention of preserving both human health and the environment from possible chemical contamination. These, together, demonstrate a commitment to sustainable development.
FDA and EU MDR Requirements: Regulatory Approval
Major Applications Medical PCBA in the Industry
Scanning Device: Common medical devices such as Ultrasound machines, X-ray machines or scanning machines all include electronic components like circuit boards for their performance.
Monitors: Different monitors used in hospitals, like machines for monitoring blood glucose levels or heart rates contain these circuit boards.
Medical Instruments: These circuits are an important part of medical research equipment like microscopes and others.
It is essential for medical PCB manufacturers to produce medical-grade products that can be easily incorporated into medical devices by the technicians. These should serve in the long run and must be durable as well. These are generally smaller in size as per the type of devices they are used for.
