Turnkey PCB Assembly Services: Precision Engineering & Full-Turnkey PCB Assembly
From component souring to final testing—your seamless partner for complex electronics with certified quality standards.
PCBArise provides turnkey PCB assembly services from component sourcing to finished product assembly. Our capabilities include SMT assembly, THT assembly, BGA assembly, fine-pitch assembly, mixed-technology assembly, AOI inspection, X-Ray inspection, ICT, FCT, functional testing, and box build assembly.
SMT, THT, BGA and Mixed-Technology Assembly
Stop juggling multiple vendors. We consolidate the entire electronics manufacturing process under one roof, providing a seamless experience from your initial Gerber files to a fully tested, market-ready product.
● SMT (Surface-Mount Technology) Assembly: Our core competency. We utilize high-speed, high-precision pick-and-place machines capable of handling the most complex boards, from simple consumer electronics to intricate multi-layer industrial controls. We support ultra-fine-pitch components down to 01005 and 0.3mm pitch BGAs.
● Through-Hole (DIP) Assembly: For components requiring robust mechanical strength, we offer both manual insertion and automated selective wave soldering. This ensures reliable through-hole assembly without exposing sensitive SMT components to excessive thermal stress.
● BGA & µBGA Assembly: We specialize in complex Ball Grid Array (BGA) and Micro-BGA assembly. Our process includes precise X-Ray inspection to verify solder joint integrity, ensuring void-free connections for high-density ICs.
● Flexible PCB Assembly: We possess the specialized fixturing and process controls required to assemble Flexible Printed Circuits (FPC) without damaging the substrate. This includes careful handling during solder paste printing and reflow to maintain dimensional stability.
● Rigid-Flex PCB Assembly: Combining the durability of rigid boards with the versatility of flex circuits, we manage the complex assembly of Rigid-Flex PCBs. We ensure precise alignment and stress relief during the soldering process to maintain the integrity of the transition zones.
● Consigned PCB Assembly (Labor-Only): You provide the components, and we provide the manufacturing expertise. This is ideal for projects where you have established supply chains or specialized parts. We handle the kitting, storage, and precise assembly of your materials.
● Turnkey Assembly: The ultimate hands-off solution. We take your design files and a Bill of Materials (BOM), then manage everything—component sourcing, PCB fabrication, assembly, and final testing—delivering a finished product ready for integration. This minimizes your administrative overhead and supply chain risks.
● Prototype PCB Assembly: Speed is critical for R&D. We offer rapid turnaround times for prototype assembly, allowing you to verify designs and iterate quickly. Our “one-piece” capability ensures you can test your hardware without waiting for mass production slots.
● Mass Production Assembly: Whether you need a single board for R&D verification or thousands of units for market launch, our scalable production lines adapt to your volume and timeline. We maintain strict quality consistency across high-volume runs using Statistical Process Control (SPC).
● Component Sourcing: Our global supply chain network ensures access to genuine, high-quality parts from authorized distributors. We mitigate the risk of shortages or counterfeit components through rigorous Incoming Quality Control (IQC).
● IC Programming & Firmware Flashing: We can program Flash, MCU, FPGA, and EEPROM chips directly on the assembly line. This automated process ensures accurate firmware loading and reduces your post-production handling time.
● Conformal Coating: We apply protective coatings (Acrylic, Silicone, UV Curable, or Parylene) to shield your PCBs from moisture, dust, chemicals, and corrosion. This is essential for automotive, medical, and industrial electronics operating in harsh environments.
● Box Build Assembly: We go beyond the bare board. Our team integrates your PCBA into enclosures, installs displays, connects wiring harnesses, and performs final system assembly, delivering a complete unit ready for shipment.
● Cable & Harness Assembly: We manufacture custom cable assemblies and wire harnesses to connect your electronic components. Our processes ensure correct crimping, continuity, and strain relief, matching the high quality of your PCBs.
