As today’s technology is advancing at an unprecedented rate, medical processes and treatments are becoming increasingly computerized. This evolution makes the medical industry one of the frontrunners in utilising Printed Circuit Board Assemblies (PCBAs) in a wide range of complex devices and equipment. These devices, ranging from MRI machines to surgical robots, rely heavily on PCBs to function effectively. 

Absolute EMS holds 29 years of experience in ISO 13485-certified manufacturing of PCBAs for medical products. Our experience ranges from Instrumentation, Surgical instruments, and Endoscopy products to Surgical Robotic Arms. The company has become one of the most reliable and trusted manufacturers of PCBs for the high-precision sectors like defense, aerospace, satellite communication, and medical manufacturing. Notably, our origins lie in servicing the medical industry.

The production of PCB assemblies in a critical sector, such as medical, must adhere to strict protocols. Medical PCB assembly includes designing and manufacturing PCBs to meet the stringent quality, reliability, and regulatory requirements. These are the key considerations for PCB production for the medical industry.

Reliability

The healthcare or medical industry is a critical sector that witnesses life-saving processes. Here, reliability is non-negotiable. 

Many medical devices, such as several endoscopy equipment, require high-precision functionality of PCBs. In such high-stakes situations, even the slightest defect in the PCB assembly can compromise the entire medical treatment plan. 

A reliable PCB manufacturer for the medical industry would utilize advanced inspection techniques and high-quality materials that would ensure their assemblies withstand harsh operating conditions without failure for a longer duration.

Tips to ensure reliability for PCB manufacturers

• Medical PCBs must be made to endure temperature fluctuations, moisture, and medical vibrations common in medical environments.
• Rigorous testing is very crucial in PCB production for medical manufacturing and should include thermal cycling, accelerated ageing, and electrical stress tests to ensure long-term reliability.
• Strict quality control systems with traceability of materials and processes are essential for compliance and recall management if needed.
  

Precision and Miniaturization

Medical devices, especially modern medical devices, require increasingly complex and compact electronics. These advanced devices help ensure patient comfort, faster recovery, and improved diagnostic accuracy. 

Miniaturisation enables the formation of minute devices, and precision ensures that the PCB production checks safety standards and protocols. Both of which are critical in medical device manufacturing.

Tips to incorporate precision and miniaturization for PCB manufacturers

•  Precision placement of components via automated assembly reduces human error and improves yield.
• Using high-resolution imaging techniques, such as laser direct imaging (LDI), ensures better alignment and accuracy than traditional methods.
• Shift from through-hole to SMT-only designs saves space and increases reliability.
• Multi-layer PCBs with controlled thickness, eg, a 6+ layer board, optimize signal integrity and electromagnetic compatibility (EMC). It proves to be critical for sensitive medical electronics.
  

Absolute EMS is an ISO 13485-certified manufacturing company offering reliable PCBs with the ability to automatically place and inspect the smallest components in the industry, including the 008004 Imperial Code.

Regulatory Compliance and Certifications

Medical PCBs must comply with stringent regulatory requirements to ensure safety and effectiveness. 

Must-have standards and certifications for PCB manufacturers

• ISO 13485 – This standard ensures that PCB assembly manufacturers adhere to strict quality control and documentation procedures.
• IPC-A-610 – This specifies the acceptability criteria for electronic assemblies, including workmanship quality and reliability. 
• In-line inspection capabilities – These include advanced inspection technologies such as 3D Solder Paste Inspection (SPI), 3D Automated Optical Inspection (AOI), and X-Ray Inspection using the 3D Dage Quadra 3 System. ​​These inspection methods are critical for detecting initial defects and ensuring the highest quality standards, especially in high-stakes sectors like medical manufacturing.

At Absolute EMS, we are proud to be ISO 13485:2016 certified, demonstrating our commitment to the highest quality standards in medical manufacturing. With almost 29 years of experience producing medical products, we support the full lifecycle of the product, from New Product Introduction (NPI) through end-of-life.
