Hhcircuits’ Medical PCBs Designs

Hhcircuits’ approach to medical PCB design encompasses a meticulous and systematic process aimed at ensuring the reliability, precision, and safety of the final product. Here’s an overview of the medical PCB design process:

Step 1: Build Schematic
The initial step involves building a schematic, providing a visual representation of electronic components and connections within the printed circuit board. This enables engineers to identify and rectify potential issues before production. Customer-provided project details, such as intended use, type of circuit board, required power, and materials, form the basis for the initial medical device PCB design.

Step 2: Layout Design
The subsequent stage entails professional layout design using PCB design software. It is crucial to arrange components compactly due to the widespread use of miniaturized medical devices. Adhering to PCB design guidelines, maintaining short trace lengths, implementing power and ground planes, and considering thermal management are essential for reliable and efficient PCB operation.

Step 3: Files for Final Work
Once the design is complete, the final step involves sending the Gerber or CAD data to the medical PCB assembly manufacturer. Choosing an ISO 13485-certified manufacturer is crucial for medical PCB projects to ensure compliance with quality standards. Hhcircuits offers expertise and quality assurance as one of the leading medical PCB manufacturers, enabling customers to proceed with confidence.

Hhcircuits’ commitment to precision and quality ensures that its medical PCB designs meet the stringent requirements of the healthcare industry, contributing to the advancement of medical technology and patient care.

Hhcircuits’ Medical PCBs Manufacturing

Hhcircuits’ medical PCB manufacturing process involves a series of meticulous steps to ensure the production of high-quality and reliable medical printed circuit boards. Here’s an overview of the medical PCB manufacturing process:

Step 1: Design Imaging
The process begins with a plotter printer converting design files into films, representing the printed circuit board’s copper traces and non-conductive parts. Black ink represents the copper pathways, while clear ink indicates the non-conductive regions on the PCB.

Step 2: Inner Layer Printed Copper
This involves laminating copper layers onto a fiberglass substrate, followed by UV light exposure and chemical processing to develop and etch the circuit board, forming the inner layers of the PCB.

Step 3: Combining Different Layers
The different inner layers are combined to form a complete printed circuit board, requiring precision drilling to connect with the inner layers. Hhcircuits utilizes optical drilling machines and laser drilling processes for precision in manufacturing, ensuring that any minor deviation does not compromise assembly.

Step 4: Outer Layer Imaging
The outer layer of the PCB undergoes imaging to transfer the PCB design onto the copper layers. The imaging process involves applying photoresist to the outer layer and using UV light to harden the photoresist.

Step 5: Outer Layer Etching
During this stage, unwanted copper is removed, and additional copper is added using electroplating, with inspections to ensure compliance with specifications.

Step 6: Solder Mask and Silk Screen
The circuitry is protected using a solder mask, and silk screen details are applied for identification and marking. This involves applying epoxy resin ink, UV light exposure, and inkjet printing for information detailing.

Step 7: Surface Finishing
Surface finishing processes are undertaken as per customer requirements, ensuring the application of a suitable conductive coating to the finished medical PCB.

Hhcircuits’ commitment to precision and stringent manufacturing processes ensures the production of reliable and high-quality medical printed circuit boards, crucial to the integrity and performance of medical devices in the healthcare industry.

Hhcircuits’ Medical PCBs Testing

In the development process of medical devices, extensive testing is crucial, surpassing the requirements for non-critical PCBs. Hhcircuits adheres to the stringent testing requirements mandated by regulatory agencies, including functional and production testing. Regulatory testing for medical devices typically aligns with standards such as IEC 60601-1 for equipment directly interfacing with patients and IEC 61010-1 for non-patient connected medical equipment. This underscores Hhcircuits’ expertise in medical PCB manufacturing and assembly, ensuring compliance with regulatory standards and the highest levels of quality and safety.
