Description

In today’s rapidly evolving electronics industry, microcontrollers (MCUs) are the core of smart devices, while high-quality PCB assembly ensures stable performance. As a leading PCB manufacturer with 17 years of industry experience, Topfast provides one-stop MCU procurement and PCB assembly services, helping customers reduce supply chain risks, optimize costs, and accelerate time-to-market.

Topfast MCU Procurement

We have direct partnerships with top global MCU brands, ensuring authentic components, stable supply, and competitive pricing. Whether you need STM32, ESP32, PIC, NXP, TI, or other popular models, we offer full BOM support and alternative solutions to prevent production delays due to shortages.

Key Advantages of MCU Procurement:

Direct Supply – STM, NXP, Microchip, TI, Renesas, and other authorized channels, eliminating counterfeit risks
BOM Optimization – Expert team provides cost-effective alternatives
Batch Traceability – Strict quality control ensures reliable sourcing
Obsolescence Management – Early warnings for discontinued components with upgrade recommendations

High-Precision MCU PCB Assembly

MCU performance depends not only on the chip itself but also on PCB design, soldering processes, and testing. Topfast’s advanced SMT production line supports 0.3mm fine-pitch placement, BGA X-ray inspection, and AOI/ICT testing, guaranteeing high precision and reliability in MCU PCB assembly.

Key Features of MCU PCB Assembly:

Precision Placement – Supports QFP, LGA, BGA, and other complex packages
X-Ray Inspection – Ensures defect-free BGA soldering
Firmware Pre-Programming – MCU flashing to reduce additional steps
Comprehensive Testing – AOI, flying probe, functional testing to eliminate defects
