Project Participation Workflow
We translate your structural and optical constraints into a manufacturable reality, moving systematically from selection to batch production.
Specification & Selection
You submit target wavelength, PCB size, LED layout, power input, connector type, mounting hole position, and application context. We confirm feasible LED emitter selection.
PCB Layout Review
Our engineers review the PCB drawing to verify heat dissipation paths, electrical routing, and mechanical fit within your device housing.
SMT Assembly & Module Build
Executing SMT placement with strict consistency checks, soldering components, and assembling the PCBA module according to the approved BOM.
Sample Testing & Batch Production
Upon sample approval, we lock in the production parameters to ensure batch-to-batch consistency for your annual demand.
Functional Spectrum Experience
We do not make medical efficacy claims. Our role is to provide device manufacturers with the precise LED light sources and board solutions that match their structural requirements and target application goals.
Common Project Wavelengths:
- 630nm (Red)
- 633nm (Red)
- 660nm (Deep Red)
- 810nm (NIR)
- 830nm (NIR)
- 850nm (NIR)
- 940nm (NIR)
- UV Wavelengths
- Full Spectrum & Custom Combinations
Engineering & Production Floor
Buyers often worry if the LED layout will fit the housing, if mounting holes align with structural parts, or if heat dissipation will affect continuous operation. Our value is confirming these physical realities at the sample stage, ensuring the BOM and test standards remain identical through mass production.
Testing & Batch-to-Batch Consistency
Our testing protocols help clients reduce parameter drift, assembly rework, and incoming inspection time between sample approval, pilot runs, and volume purchasing.
- Wavelength range check & binning
- Forward voltage test & brightness bin sorting
- LED aging test & thermal behavior observation
- Batch traceability documentation
The Leienda Structural Advantage
Consolidating the supply chain for functional lighting projects to reduce repetitive engineering confirmations.
Standard Fragmented Procurement
- Separate Suppliers: Managing different vendors for LED beads, bare PCBs, SMT processing, and final testing.
- Communication Overhead: Translating optical requirements to the PCB layout team, then explaining assembly constraints to the SMT factory.
- Risk of Disconnect: Sample modifications require synchronizing changes across multiple independent suppliers, increasing the risk of mass production errors.
Unified Production Communication
- Centralized File: LED selection, board structure, SMT processing, PCBA assembly, and testing requirements are managed within a single project file.
- Faster Modifications: Sample modifications are centralized. If a connector position changes, we update the layout and assembly instructions simultaneously.
- Consistent Mass Production: Mass production documentation is strictly tied to the approved sample BOM, ensuring no unauthorized component substitutions.
