PCB Fabrication and Assembly from Prototype to Production
We support PCB fabrication, component sourcing, assembly, inspection, and testing. Send us your project files for review.
Why Topline Circuit
Keep your PCB and PCBA project moving from file review to production.
We review project files, materials, components, assembly requirements, inspection methods, and testing needs before production starts.
Project Review Image
Project file review before production
Send Gerber files, BOM, CPL, assembly drawings, programming needs, inspection criteria, and test requirements.
- DFM, stack-up, and package checks
- BOM and assembly file review
- Inspection and test planning
Solutions
PCB layout, fabrication, assembly, and prototyping
PCB Fabrication
Flexible, rigid-flex, HDI, RF, high-frequency, High-Tg, heavy copper, and custom PCBs.
PCB Prototyping
PCB and PCBA prototypes for design checks, inspection, and production planning.
The Topline Process
One process from project files to tested assemblies
We review files, materials, components, production steps, inspection, and testing together. This helps reduce gaps between teams.
Connected Process
Fabrication, sourcing, assembly, inspection, and testing stay in one project workflow.
Risk Review
We review design, sourcing, and production risks before production.
Project Updates
We send clear questions, approvals, and production updates.
Materials
Material review for electrical and production needs
We review thermal, electrical, mechanical, and fabrication needs before selecting the material system.

Fabrication Review
Stack-up, vias, copper, impedance, and surface finish
We review the fabrication details that affect performance, manufacturability, and inspection.
Assembly and Test
Packages, reflow, inspection, programming, and testing
We align assembly and test requirements with the PCB structure, component packages, and project files.
