At TOPFAST, we are continually improving how customers interact with our engineering and manufacturing teams.
To streamline the submission process for PCB assembly projects, we have officially launched a dedicated PCB Assembly Inquiry page.
The Page allows engineers, purchasers, startups, and OEM companies to submit PCB assembly requirements more efficiently, helping our team review project specifications and provide manufacturing support faster.
Whether you need prototype assembly, low-volume production, turnkey PCBA, or full-scale manufacturing, the new inquiry page provides a centralized channel for project evaluation and quotation requests.

Why We Created a Dedicated PCB Assembly Inquiry Page
PCB assembly projects often involve much more than PCB fabrication alone.
A complete PCBA project may require:
- PCB Fabrication
- Component Procurement
- SMT Assembly
- Through-Hole Assembly
- Functional Testing
- Programming
- Final Inspection
- Box Build Integration
Managing these requirements through general contact forms can slow down communication and project evaluation.
The new PCB Assembly Inquiry page was created to help customers submit technical requirements more clearly and allow our engineering team to review projects more efficiently.
