Turnkey PCB Assembly Manufacturing Surface Mount PCB Fabrication and Assembly Prototype

HTF delivers custom prototype HDI multilayer PCB and PCBA board manufacturing services with complete circuit board fabrication and certified PCBA prototype assembly from Guangdong, China. This integrated PCB fabrication and assembly service provides electronics development teams with a single-source supplier for prototype HDI multilayer boards from concept through assembled and tested PCBA delivery. Manufacturing specifications include 1-24 layer rigid PCB constructions on FR4, aluminum, ceramic, and CEM1 base materials with 0.4-6mm board thickness, customized board dimensions up to 1200mm maximum, and copper weight options from 0.5-6 OZ with standard 1 OZ and 2 OZ offerings. Precision manufacturing at 0.15mm/3-4mil minimum line width and spacing with 0.15mm minimum hole size supports the dense routing and microvia interconnections required for HDI multilayer designs. Surface finishing options including HASL for cost-effective general purpose, immersion gold for fine-pitch and wire bonding applications, flash gold for edge contacts, plated silver for high-frequency performance, and OSP for lead-free assembly compatibility provide the appropriate finish for each design's specific requirements. Solder mask colors in blue, green, red, black, and white support visual identification and aesthetic requirements. One-stop OEM service covers the complete manufacturing process from PCB fabrication through component assembly, AOI and X-Ray inspection, functional testing, and final packaging with 1-year warranty coverage and ISO9001/ISO14001/CE/RoHS certifications.

This custom prototype HDI multilayer PCB and PCBA manufacturing service supports diverse electronics development and production applications. Consumer electronics developers utilize our prototype PCB service for smartphone peripheral boards, wearable device PCBs, and smart home controller modules where 1-24 layer capability and multi-material options support compact high-density designs. Industrial equipment manufacturers depend on our certified manufacturing for automation controller PCBs, sensor interface modules, and motor drive boards where ISO9001 certification and comprehensive testing ensure reliable operation. Automotive electronics suppliers leverage our rigid PCB fabrication for body control modules, LED lighting boards, and infotainment interface PCBs where aluminum substrates provide thermal management. IoT product teams use our prototype-to-production service for gateway devices, wireless sensor nodes, and connected device control boards with FR4 and ceramic material options. Medical device developers partner with us for diagnostic equipment PCBs and monitoring device assemblies where CE and RoHS compliance supports regulatory requirements.

Each PCB and assembled PCBA is individually vacuum-sealed in anti-static packaging with desiccant, then packed in protective export-grade cartons measuring 32.0*32.0*32.0 cm per single unit with 0.5 kg gross weight. Our ISO9001 and ISO14001 certified quality and environmental management systems govern every manufacturing stage from incoming raw material inspection through final functional testing and packaging. Incoming base materials including FR4, aluminum, ceramic, and CEM1 substrates undergo specification verification including dielectric properties, dimensional tolerance, and surface quality inspection. PCB fabrication employs controlled etching for 0.15mm/3-4mil minimum line width and spacing with copper thickness options from 0.5-6 OZ per customer requirements. Surface finishing processes including HASL, immersion gold, flash gold, plated silver, and OSP are applied per design specifications to ensure optimal solderability and shelf life. Comprehensive testing includes automated optical inspection for trace quality and registration, X-ray inspection for internal layer alignment and hidden interconnection verification, and functional testing for electrical continuity and performance. ISO9001 quality management, ISO14001 environmental management, CE product safety, and RoHS material compliance certifications support customer quality audits and product conformity for international markets. A 1-year warranty covers manufacturing defects for all PCB and PCBA products.
