HMLV Manufacturing

Flexible Manufacturing

Low volume; High mix; High reliability; Small-batch programs delivered with disciplined high-reliability standards

A stable manufacturing path for low-volume, high-mix programs

For prototypes, trial production, and low-volume manufacturing, Ledge brings material, process, test, and supply-chain judgement forward before production starts; Volumes may be small and product mix may be complex, but the delivery process must remain planned, traceable, and repeatable

Operating Logic

Delivery Baselines for Flexible Manufacturing

Fast delivery does not mean removing quality gates; It means moving material confirmation, PCB fabrication, stencil, programming, first-article preparation, and scheduling forward in parallel so R&D validation waits for fewer handoffs

4000+4000+ batches / yearFrontline experience built from low-volume, high-mix programs across industrial, medical, marine, rail, and other demanding sectors

  1. 01

    Early R&D assessment

    Confirm critical materials, substitution risks, and long-lead items before the program is blocked by supply chain

  2. 02

    Materials and PCB launch together

    Spot procurement, authorized-channel checks, and accelerated PCB fabrication move in parallel

  3. 03

    Engineering preparation in parallel

    Programming, stencil, first-article files, and process documentation are completed before PCB arrival

  4. 04

    Compact production scheduling

    Once PCBs arrive, the job moves directly into production rhythm with fewer idle handoffs

  5. 05

    Validation-ready delivery

    As fast as 7 working days for 10 PCBA units ready for customer validation

"Moving manufacturing judgement into the design stage significantly improved our NPI efficiency; We did not expect a 7-working-day delivery to be achievable" — Project Manager, European industrial customer
Manufacturing Network

One Standard, Coordinated Across Manufacturing Nodes

Shenzhen Bao'an anchors process, supply-chain, and quality-control standards; Shenzhen Longgang supports flexible capacity; a future Canada node is planned to bring manufacturing and service closer to North American customers

Base Role

Shenzhen Bao'an Base (Process and Quality Hub)

SMT Line
Automatic solder paste printing, 3D SPI, YAMAHA YSM10 + YSM20R, 10-zone reflow, inline AOI
Inspection and Rework
4 offline AOI systems, 3 SMT intelligent first article inspection instruments, X-Ray, BGA rework station
DIP and Assembly
Selective wave soldering, automatic soldering, insertion line + wave soldering, ICT/FCT, conformal coating, assembly line
Supporting Services
CNC, 3D printing, injection molding

Shenzhen Longgang Base (Flexible Capacity)

Built with a partner to absorb higher-tempo SMT demand, larger DIP work, and expanded assembly space during temporary capacity peaks

Future Plan: Canada Manufacturing Node

A planned manufacturing and service node for North American customers; It is described as future capability development, not an operating production base

Engineering Discipline

Frontline Experience Built Into Engineering Capability

True flexible manufacturing depends not only on equipment parameters, but on the team's ability to turn experience into tools, process discipline, and traceability systems

The SMT intelligent first article inspection instrument was led by the company founder and core team members more than a decade ago and deployed in real production; It still reflects an advanced understanding of error prevention and traceability in electronics manufacturing; Its value is not the device alone, but the engineering judgement behind it: years of confronting human-error risk, frequent batch changeover, and traceability demands in high-reliability production, then turning that frontline experience into a repeatable process

Reduce human-error risk

Automatic comparison of component parameters moves missed or incorrect inspection risk into the first-article stage

Preserve process records

Inspection results are archived for batch traceability and abnormality review

Reflect industry depth

Only a team deeply rooted in high-reliability manufacturing would turn this kind of pain point into a tool

Experienced engineering team

Soldering specialists with 10+ years of IPC-A-610 Class 3 experience; dedicated NPI and process engineers; daily changeover across 10+ product types; proprietary tracking system for full-process traceability
