Turnkey PCBA

What is Turnkey PCBA? The Ultimate Partnership Model

Turnkey PCBA (Full Turnkey) is the most comprehensive electronics manufacturing service model. Under this arrangement, SENTAK assumes complete responsibility for the entire production process beyond providing the design files (Gerbers, BOM, Assembly Drawings). This includes sourcing all electronic components, managing the supply chain, performing PCB fabrication and assembly, conducting rigorous testing, and managing final logistics. You provide the intellectual property; we deliver a fully functional, tested product ready for integration or shipment. This model transforms us from a vendor into a true extension of your manufacturing operations, eliminating your logistical burden and mitigating supply chain risk.

Factors That Affect Turnkey PCBA Cost

PCB Complexity

Layer count, material type, board dimensions, copper thickness, HDI structures, controlled impedance and surface finish all influence bare PCB cost.

Component Availability

Common components with stable availability are generally easier to source. Obsolete, allocated, long-lead-time or single-source components may increase cost and delivery risk.

Component Package

Fine-pitch BGAs, QFNs, CSPs, LGAs and miniature passive components require more precise printing, placement and inspection processes.

Assembly Density

A board with a high number of component placements requires additional machine programming, assembly time and inspection.

Production Quantity

Prototype orders have setup and engineering costs distributed across a small number of units. Larger orders may achieve a lower unit manufacturing cost.

Testing Requirements

Functional testing, programming, burn-in testing and custom fixture development require additional engineering and production resources.

Delivery Schedule

Expedited projects may require priority component sourcing, engineering review and production scheduling.

BOM or Design Changes

Changes made after component procurement or production preparation has started may affect material cost, lead time and engineering charges.

To improve cost predictability, SENTAK provides quotations based on an approved BOM, confirmed production files and a stated quotation-validity period.
