About Topline Circuit
Company Overview
Topline Circuit provides PCB manufacturing, PCB assembly, component sourcing, and engineering support for customers worldwide. With more than 15 years of industry experience, we support projects from prototype development to volume production.
Our capabilities include rigid PCBs, multilayer PCBs, flexible PCBs, rigid-flex PCBs, HDI PCBs, RF and microwave PCBs, controlled impedance PCBs, heavy copper PCBs, and other custom circuit boards.
We work with equipment manufacturers, engineering teams, system integrators, brand owners, and other businesses that need reliable PCB and PCBA support.
Engineering Support
Our engineering team reviews PCB designs for manufacturability before production. We help identify potential issues involving board structure, materials, stack-up, impedance, component placement, assembly, and testing.
Free DFM support helps customers reduce avoidable production risks and prepare their designs for stable manufacturing.
Manufacturing Capabilities
We continue to improve our PCB fabrication, assembly, inspection, and testing capabilities to support increasingly complex electronic products.
Our services include:
- PCB prototyping and production
- SMT and through-hole assembly
- BGA assembly
- Turnkey and partial-turnkey component sourcing
- AOI and X-ray inspection
- ICT and functional testing
- Component programming
Customer Support
Clear communication is essential throughout a PCB project. Our team responds to technical questions, provides production updates, and helps customers resolve manufacturing issues from quotation through delivery.
We support quantities from one prototype to production orders without a minimum order quantity.
Practical Value
We review materials, manufacturing processes, component sourcing, and testing requirements according to each project. This helps customers control costs without overlooking performance, reliability, or manufacturability.
Quality Management
Topline Circuit operates under an ISO 9001 quality management system and provides UL-recognized PCB manufacturing. Our production and inspection processes are designed to maintain consistent quality across prototypes and repeat orders.
