PCBA Prototyping

A functional PCBA prototype is the indispensable bridge between a theoretical design and a viable product.It is the stage where electrical functionality is validated, mechanical fit is confirmed, and thermal performance is assessed.Rapid, high-fidelity prototyping is a competitive advantage, allowing for faster iteration, earlier user testing, and a shorter path to market.At SENTAK, we treat your prototype with the same engineering rigor as production volumes, ensuring that the lessons learned are directly applicable to scaling up, eliminating costly surprises later.

We go beyond simply assembling components quickly. We provide a knowledge-rich prototype that advances your design maturity.

We are equipped to handle prototype complexities, from simple boards to advanced systems.

1. Assembly&Technology Scope

Standard SMT&THT Assembly

Mixed-Technology&Complex Mechanical Integration

Fine-Pitch BGA(down to 0.3mm pitch)and 01005 Components

Flex&Rigid-Flex PCBA Prototypes

Board Formats: Rigid, Flexible, Metal-Core, and Hybrid Constructions.

2. Turnaround Tiers(From File Release)

Super-Rush: 24-48 Hours(For critical design verification milestones)

Standard Rush: 3-5 Business Days(Our most balanced option for speed and thorough review)

Complex Build: 5-10 Business Days(For boards with advanced technologies, special materials, or full box-build integration)

3. Included Value-Added Services(Standard with every prototype)

BOM&CAD Data Review: Check for errors, obsolete parts, and sourcing alternatives.

Design for Manufacturability(DFM)Report: Detailed analysis of your design against IPC standards and our process capabilities.

Design for Assembly(DFA)Feedback: Suggestions to reduce assembly cost and improve reliability.

X-Ray Inspection: For BGAs, QFNs, and any hidden solder joints.

Basic Power-On/Functional Validation: Per customer-provided test procedure.

Our process is designed for transparency and technical collaboration.

Instant Online Quote&Feasibility Check: Upload your BOM, Gerber, and Pick-and-Place files. Our platform provides an immediate preliminary quote and flags any obvious technology constraints.

Project Kick-off&NPI Engineer Assignment: A dedicated New Product Introduction(NPI)Engineer becomes your single point of contact, managing the build and providing technical liaison.

Deep-Dive Engineering Review(The"SENTAK Difference"): Your NPI engineer conducts a comprehensive review, culminating in a Prototype Readiness Report sent for your approval. This report includes component sourcing status, DFM findings, and a build plan.

Procurement&Kitting: For Turnkey builds, we source all components from our certified network, handling shortages and alternates.

Precision Assembly&In-Process Inspection: Assembly proceeds with SPC monitoring. High-resolution photos are taken at key stages(paste print, post-placement).

Testing, Reporting&Delivery: The assembled prototype undergoes agreed testing. You receive the Prototype Delivery Pack and the physical units via your chosen expedited courier.

Following these guidelines ensures the smoothest,fastest possible turnaround.

1. Data Package Requirements

Provide a complete,consistent package to avoid delays:

Gerber Files(RS-274X): For fabrication.

Accurate Bill of Materials(BOM): CSV/Excel with Manufacturer Part Numbers(MPN),References,Values,and Digi-Key/Mouser part numbers are highly preferred.

Pick-and-Place File: XYRS coordinates(Center X,Center Y,Rotation,Side).

Assembly Drawing: PDF showing component outline,polarity,and any special instructions.

Simple Test Procedure(Optional but Recommended): A list of"power-on"checks or key measurements.

2. Design for Prototyping(DFP)Tips

Maximize Testability: Include test points for all critical power rails and signals.

Plan for Re-work:Avoid placing critical components on both sides directly opposite each other if possible.

Communicate Clearly: Note any"DNP"(Do Not Populate)components,firmware version requirements,or specific component orientation needs in your drawing.

Leverage Our Expertise: "What's the fastest path to a working prototype of my design?"Contact us even during the schematic phase for a feasibility discussion.

A SENTAK prototype is the first step in your production journey, not a disconnected event.

Process Continuity: The same NPI engineer often transitions with your project to production, ensuring knowledge transfer.

Data Inheritance: All manufacturing data(stencil files, assembly programs, test fixtures)created for the prototype is archived and refined for production use.

Volume Ramp Planning: Our Prototype-to-Production(P2P)Report outlines a clear roadmap, identifying lead time drivers and potential bottlenecks for scaling.

Don't let a slow or low-fidelity prototype become the bottleneck in your development cycle.Partner with SENTAK for a prototyping experience that delivers not just boards,but clarity,confidence,and a faster path to market success.
