Our Electronic Design Process
A structured engineering process that turns your product requirements into a tested, manufacturable electronic design ready for production.
Step 1 — Requirements & Feasibility Review
-
Share your product functions, interfaces, power requirements, dimensions, target cost, application environment, and existing technical files.
Step 2 — Schematic & Component Design
-
Our engineers develop the circuit architecture, create the schematic, select suitable components, and prepare the initial BOM.
Step 3 — PCB Layout & Prototype Build
-
After schematic approval, we complete component placement, PCB routing, DFM review, and prototype PCB fabrication and assembly.
Step 4 — Testing & Production Release
-
The prototype is tested and debugged according to the agreed requirements. Approved design files are then prepared for pilot runs or volume production.
Electronic Design Services and Deliverables
Cheng Jie Da supports electronic product development from requirements analysis and circuit design to PCB layout, prototype validation, and production release. The exact service scope and deliverables are defined according to your product functions, development stage, and manufacturing requirements.
| Design Stage | Purpose | Key Activities & Deliverables |
|---|---|---|
| Requirements Analysis | Define the product’s technical and commercial objectives | Review product functions, operating environment, dimensions, interfaces, power requirements, target cost, and production quantity |
| Feasibility Review | Evaluate whether the proposed product concept can be implemented | Assess technical risks, component availability, development requirements, estimated complexity, and manufacturing feasibility |
| System Architecture | Establish the overall electronic system structure | Define functional blocks, power architecture, control logic, communication interfaces, sensors, and major components |
| Schematic Design | Convert product functions into an electronic circuit | Create circuit schematics, define interfaces, select components, and complete an engineering design review |
| Component Selection | Build a practical and supply-ready BOM | Select components based on electrical performance, availability, lifecycle status, lead time, and target cost |
| PCB Layout Design | Transform the schematic into a manufacturable PCB | Complete component placement, multilayer routing, grounding, power distribution, thermal planning, and board outline design |
| DFM & DFT Review | Reduce production and testing risks before prototyping | Review footprints, spacing, solderability, panelization, test points, programming access, and assembly requirements |
| Prototype Development | Produce physical samples for design verification | Prepare manufacturing files, fabricate PCBs, source components, assemble prototypes, and support initial programming |
| Testing & Debugging | Verify agreed product functions and identify design issues | Perform power-on checks, interface testing, functional verification, measurements, debugging, and revision analysis |
| Production Release | Prepare the approved design for pilot or volume production | Finalize Gerber files, BOM, pick-and-place data, assembly drawings, test requirements, and revision-controlled documents |

Whether you're validating a new design or preparing for production, our PCBA service helps you move forward with confidence.
Practical Electronic Design for Reliable Production
Integrated engineering support helps transform your product requirements into a functional, testable, and manufacturable electronic design.
Why Choose Cheng Jie Da for Electronic Design?
Cheng Jie Da connects electronic engineering with PCB manufacturing and assembly. Our team considers product functions, component availability, PCB structure, testing, production feasibility, and target cost throughout the development process. This integrated approach helps identify potential design and manufacturing issues before volume production, reducing unnecessary revisions and supplier handoffs.
-
Design-to-Manufacturing Support: Connect schematic design, PCB layout, prototyping, assembly, and testing within one workflow.
-
Practical Component Selection: Evaluate electrical performance, availability, lifecycle status, lead time, and cost.
-
DFM & DFT Review: Review component footprints, spacing, solderability, test points, and production requirements.
-
Flexible Engineering Support: Support complete hardware development or specific stages of an existing project.
From Prototype Validation to Production Release
A design is not complete until it can be manufactured and tested consistently. After schematic and PCB layout approval, Cheng Jie Da can coordinate prototype fabrication, component sourcing, PCB assembly, programming, and agreed functional testing. Prototype results and identified issues are reviewed before design files are finalized. Approved production documents can then be released for pilot builds or volume manufacturing.

Frequently Asked Questions
Get clear answers about our electronic design process, project requirements, deliverables, prototyping, and production support.
What information do you need to start an electronic design project?
Please provide the required product functions, power specifications, interfaces, dimensions, operating environment, target cost, and expected production quantity. Existing schematics, PCB files, samples, drawings, or reference products can also help us evaluate the project.
Can you improve an existing electronic design?
Yes. We can review existing schematics, PCB layouts, BOMs, prototypes, and test results to identify potential performance, component availability, manufacturability, and cost issues. The service scope is confirmed after reviewing the available files.
Do you provide both schematic design and PCB layout?
Yes. We can support circuit architecture, schematic capture, component selection, PCB placement, multilayer routing, and manufacturing file preparation. Customers can request complete hardware development or support for a specific design stage.
Can you build and test prototypes after completing the design?
Yes. Cheng Jie Da can coordinate PCB manufacturing, component sourcing, prototype assembly, programming, and agreed functional testing. Prototype results can then be used to support debugging and design revisions before production.
What files will I receive when the design is completed?
Depending on the agreed project scope, deliverables may include schematic files, PCB layout files, Gerber files, BOM, pick-and-place data, assembly drawings, and test requirements. File formats, ownership, and delivery terms should be confirmed before the project begins.
