Ledge is headquartered in Hong Kong Science Park, with a branch in Ontario, Canada, R&D teams in Cyprus and Spain, and core manufacturing and quality operations in Bao'an, Shenzhen; we deliver 4,000+ batches each year for NPI, low-volume production, and high-complexity electronics programs

4000+Annual project batchesMore than 4,000 project batches handled each year, covering NPI, low-volume, high-mix, and recurring programs

90%+Proprietary system coverageThe proprietary order tracking system covers 90%+ of active production projects, making progress, reports, and material batches traceable

0Major defectsThe zero-major-defect target is supported through process review, inspection records, and batch verification for high-reliability projects

7 daysFastest deliveryWhen key materials are controlled and engineering work runs in parallel, Layout-to-qualified-PCBA delivery can be completed in as fast as 7 working days

5M+Board-level deliveries over 10 yearsMore than 5 million board-level products delivered over the past decade, building experience across industries, process windows, and batch consistency

20+Countries servedCustomers served across Nordic, North American, Western European, and Chinese markets, supporting cross-time-zone engineering and manufacturing collaboration

For demanding customers, trust is not a one-time audit; it is proven batch after batch

Operating Model

Delivery discipline for complex electronics

From design judgment and sourcing strategy to manufacturing execution and traceability, Ledge runs one engineering system for NPI, frequent revisions, and long-term low-volume programs

Engineering Chain

Turning uncertainty into controlled process

EOL components, complex coating, test systems, and certification support all return to one standard: can this batch be manufactured, traced, and repeated

4000+annual batches

Proven in Projects

Engineering proof where projects get difficult

Cases are based on real projects. Public pages anonymize customers, suppliers, and model numbers while preserving the engineering facts and delivery outcomes

Case 01

Deep-Sea Conformal Coating

Challenge

One PCBA required multiple coating zones and underfill, with the product expected to operate long-term in deep-sea conditions

Solution

Defined a selective coating process window, validated alternative materials, and brought coating parameters, material lots, and inspection records into traceability

Result

Stable delivery created a reusable process base for later NPI work

Case 02

Test System Rebuild with Incomplete Documentation

Challenge

Customer documentation was incomplete and original engineering support was unavailable, while multiple control boards still required one test platform

Solution

Analyzed interface behavior from the requirements list, rebuilt the test logic, and delivered hardware, host software, and 56 firmware iterations

Result

Delivered in under three months, supporting stable testing across multiple control boards

Case 03

Display Module End-of-Life Replacement

Challenge

A critical display module reached end of life, making the original delivery schedule unreliable and exposing the product to delay risk

Solution

Selected alternative screens and designed a compatible driver board to preserve existing firmware and system investment

Result

Prototype validated in six weeks, reducing MOQ pressure and preserving future supply options

Case principle

We do not use customer names as marketing material. The point is to show why the project was difficult and how Ledge made it work

Sector Experience
