JL JEELANG OPTOELECTRONICS

Design & Manufacturing Capabilities

Two things under one roof: the engineering that designs your power solution, and the factory that builds it.

Solution Design

What our R&D team delivers before anything goes to production.

01

Topology & Circuit Design

Flyback, LLC, PFC and BLDC driving topologies selected for efficiency, cost and EMC margin.

02

Firmware & Control

Motor control algorithms, dimming protocols (PWM / 0–10V), protection logic and smart-connectivity firmware.

03

Thermal & EMC Engineering

Layout and component choices optimized for temperature rise, surge and EMI — aligned to your target market's standards.

04

Rapid Sampling

Working samples typically within weeks, with test reports, for your validation before mass production.

Solution Platform · Board Gallery

Manufacturing & Quality

How we keep million-piece consistency.

SMT Lines

High-speed placement with AOI inspection for boards — from prototypes to volume batches.

In-Circuit & Aging Tests

ICT, functional testing and batch aging on power supplies and control boards before shipment.

Traceable Production

Batch records and component traceability for quality accountability.

Flexible Volumes

From pilot runs for new projects to scheduled volume production for steady programs.

How We Work With You

01

Requirement

You share the spec: output, load, size, interface and certification target.

02

Solution Review

We propose topology, BOM orientation, dimensions and cost frame.

03

Sampling & Validation

Samples built and tested; you validate in your end product.

04

Certification Support

Design adjustments and documents aligned to your market's scheme.

05

Mass Production

Scheduled production with incoming/outgoing inspection and aging tests.

06

After-Sales Engineering

Failure analysis, revisions and continuous improvement support.
