• High-Precision Manufacturing Capability: Minimum hole size of 0.15mm combined with 0.15mm minimum line width and spacing supports high-density interconnect designs with fine-pitch BGA, QFN, and 0201 component placement accuracy, meeting the requirements of miniaturized modern electronics across consumer, industrial, and automotive sectors.
• Multiple Surface Finish Options: Comprehensive finishing portfolio including OSP for cost-effective flat pad preservation, immersion gold for superior oxidation resistance and extended shelf life, immersion tin for excellent solderability, and immersion silver for high-frequency signal integrity, enabling selection based on application requirements and budget considerations.
• Heavy Copper Support up to 6OZ: Copper weight options from 0.5OZ to 6OZ accommodate both standard signal-layer designs and high-current power distribution networks, with thick copper layers providing enhanced current carrying capacity and improved thermal dissipation for power electronics and motor control applications.
• IATF1649 Automotive-Grade Quality: Manufacturing processes certified to IATF1649 automotive quality management standards, emphasizing defect prevention, process capability analysis, and continuous improvement methodologies that exceed conventional ISO9001 requirements and meet the demands of automotive tier-one suppliers.

This one-stop prototype PCB assembly service addresses a wide spectrum of electronic product development scenarios where rapid turnkey manufacturing is essential. Automotive electronics suppliers leverage our IATF1649 certified production for ECU prototypes, sensor interface modules, LED lighting controllers, and infotainment system boards that require strict process control and full traceability documentation. Industrial control system developers utilize our precision multilayer capability for PLC expansion modules, motor drive boards, power supply units, and human-machine interface controllers operating in harsh electrical environments with elevated temperatures. Consumer electronics brands partner with us for smart home hub controllers, wireless charging modules, portable power banks, and IoT gateway devices where compact form factors and consistent manufacturing quality directly impact end-user experience. Telecommunications equipment manufacturers rely on our controlled impedance capability for RF front-end modules, signal repeater boards, and network interface cards requiring precise dielectric properties and minimal signal loss. Medical device developers choose our service for diagnostic interface boards, patient monitoring modules, and portable therapeutic devices where regulatory compliance, documented traceability, and consistent manufacturing repeatability are non-negotiable requirements.

Each assembled prototype PCB is individually vacuum-sealed in anti-static moisture barrier packaging with desiccant and humidity indicator cards, then placed in protective foam-lined cartons measuring 10.0cm x 10.0cm x 10.0cm with approximately 5.0kg gross weight per unit. Our IATF1649 certified quality management system governs every production stage with documented control plans, process failure mode effects analysis, and statistical process control methodologies. Incoming components undergo verification against approved vendor lists including part number, value, tolerance, package type, and date code checks. Automated solder paste inspection monitors deposit volume, area, and height to prevent printing-related defects before component placement. Post-reflow automated optical inspection examines every solder joint for proper fillet formation, bridging, and component alignment with real-time defect classification. Electrical testing includes flying probe and bed-of-nails fixture verification of continuity, isolation resistance, and netlist conformance across all circuit nodes. For automotive-grade products, production part approval process documentation and full material compliance certification are provided with each shipment, ensuring complete traceability from component lot codes through final assembly serial numbers to meet customer quality audit and regulatory submission requirements.
