PCB layout for medical devicesPCB layout is a critical aspect of the manufacturing process for medical devices. It ensures that the devices are safe, reliable, and meet the required quality standards. Bittele Electronics, a Toronto-based turn-key PCB assembly firm, specializes in prototype and low-to-mid volume printed circuit board assembly (PCBA). The company has recently received the ISO 13485 certification for its Markham, Canada manufacturing facility, which is an internationally recognized standard that sets out the requirements for a quality management system specific to the medical devices industry. This certification ensures that the PCBs for medical devices assembled by Bittele Electronics are of the highest quality standard with repeatable and reliable results.
When it comes to PCB layout for medical devices, there are several design considerations that must be considered. One of the most critical aspects is precision, irrespective of whether it is associated with the safety or performance of the device. The PCBs in medical equipment have stringent design, performance, quality, and regulatory requirements to ensure patient safety and reliability. The PCB layout should be designed to minimize the risk of electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues. The layout should also be optimized to minimize the risk of signal integrity issues, such as crosstalk, ground bounce, and signal reflections.
Bittele Electronics has published updated Design for Manufacturability (DFM) and Design for Assembly (DFA) guidelines that detail best practices for printed circuit board (PCB) fabrication and assembly. The guidelines describe Bittele’s fabrication capabilities, suggestions for cost reductions, and design recommendations for optimizing fabrication and maximizing PCB assembly efficiency. The company’s expertise in PCB assembly for medical equipment ensures that the boards are safe, reliable, and maintain a long-life cycle.
Here are some tips to consider when designing PCB layouts for medical devices:
- Precision: The layout should be designed with precision to ensure that the device operates as planned during its entire service life.
- EMI/EMC: The layout should be designed to minimize the risk of EMI and EMC issues.
- Signal Integrity: The layout should be optimized to minimize the risk of signal integrity issues, such as crosstalk, ground bounce, and signal reflections.
- DFM and DFA: Follow DFM and DFA guidelines to optimize fabrication and maximize PCB assembly efficiency.
- IPC Class 3: Boards that are in accordance with IPC Class 3 requirements are designed to be safe, reliable, and maintain a long-life cycle.
