Topline Circuit supports quick turn PCB fabrication and assembly for NPI, prototypes, and engineering builds.
Production lead time is confirmed after reviewing the files, materials, quantity, and testing requirements.
Send the Gerber files, fabrication drawing or specifications, required quantity, and requested delivery information. For assembly projects, also provide the BOM, component placement data, assembly drawings, and any inspection or testing requirements.
Lead time depends on the board construction, materials, quantity, component availability, testing scope, and current production capacity. Topline Circuit confirms the applicable schedule after reviewing the complete project files.
Yes. Topline Circuit supports PCB fabrication and PCBA services, including SMT, through-hole assembly, BGA assembly, component sourcing, inspection, and agreed testing.
Yes. Projects may use turnkey, partial turnkey, or consigned component models. The quotation should clearly identify which parts the customer supplies and which parts Topline Circuit sources.
Yes. Topline Circuit supports prototype, low-volume, and volume PCB and PCBA projects. The appropriate process and quotation depend on the design, quantity, materials, and inspection requirements.
Topline Circuit can support projects without a fixed minimum order quantity when the design and process are manufacturable. Setup, tooling, material, and component requirements can still affect the quotation for very small orders.
Yes. Topline Circuit provides a DFM review before production to identify file conflicts, missing information, spacing concerns, stack-up issues, component-data problems, and other manufacturability risks.
Controlled impedance helps maintain predictable signal behavior. Trace width, copper thickness, dielectric thickness, material properties, spacing, and the reference plane all affect the final impedance.
The required impedance is translated into a suitable stack-up and trace geometry. The drawing should state the target impedance and tolerance. Final values and verification requirements are confirmed during engineering review.
Yes. The engineering team can review the layer structure, dielectric thickness, copper weight, material selection, impedance needs, and overall manufacturability before production.
Provide the Gerber files, drill files, fabrication drawing, stack-up, impedance requirements, and relevant specifications. For PCBA, also include the BOM, centroid or placement file, assembly drawing, polarity information, and testing requirements.
The issue is documented and sent for clarification. Production should proceed only after the required information or customer approval is received. Customer-controlled design changes should not be made without confirmation.
