Medical PCBA Application: Precision and Reliability for Healthcare Devices

Medical devices rely on PCBA precision to safeguard patient health—and STHL’s medical PCBA solutions set the standard for reliability. With 20 years in healthcare electronics, we specialize in PCBs for diagnostic equipment (MRI scanners, blood analyzers), wearable monitors, and even implantable devices (meeting ISO 13485 standards). Our services include cleanroom assembly (Class 10,000), biocompatible material selection, and full traceability (from component lot numbers to test reports). We also conduct 100% functional testing under simulated clinical conditions, ensuring every board meets FDA and CE requirements for safety and accuracy.

    Strategic Material Selection

    We source materials from reputable suppliers like Mouser, Digikey, and established platforms like Avnet and Arrow.
    We prioritize globally recognized brands and enforce strict material quality control.

    Here are our material procurement standards:

    1.Components strictly comply with the Bill of Materials (BOM) list (100% match). Deviations require customer approval for alternative part numbers.
    2.We source from Class A distributors or renowned platforms for component reliability.
    3.All components are RoHS compliant (Restriction of Hazardous Substances).
    4.Stable supplier relationships ensure faster lead times and priority delivery.
    5.Technical support is available from some brands.

    Rigorous Incoming Material Inspection:

    Meticulous inspections ensure every component meets our high standards:
    1.PCBs are inspected against precise specifications.
    2.PCBs undergo reflow testing to identify warping or discoloration.
    3.Components are thoroughly examined for damage, deformation, or defects.
    4.Components are cross-checked against the BOM for part numbers, production lots, date codes, and values.
    5.Component leads are inspected for oxidation.
