OEM Electronics Manufacturing in Taiwan

Prototype • NPI • PCB Assembly • Box Build • Production Support

Leader Global Electronics supports OEM electronics projects from prototype and New Product Introduction (NPI) through pilot builds and repeat production.

Our manufacturing support covers PCB fabrication, component sourcing, SMT & THT assembly, programming, inspection, functional testing, box build, and final assembly.

Before quotation, our engineering team reviews your project files to confirm PCB specifications, check component availability and discontinuation status, and clarify assembly and production requirements.

Please also confirm whether programming or testing is required and provide the estimated time for each operation per board or unit, if known. Firmware files and detailed test procedures are not required for the initial quotation.

Request a Manufacturing Quote

Send your BOM, available project files, required quantities, and target delivery date. Let us know whether you need PCB assembly, box build, or both.

We will review your requirements and confirm any additional information needed for quotation.

Prototype to Production

We support OEM customers through different stages of product manufacturing.

Prototype Builds

Small-quantity builds for engineering verification, firmware development, debugging, and functional evaluation.

Prototype PCB Assembly →

New Product Introduction

Engineering and manufacturing coordination for products moving from prototype into controlled production.

NPI PCB Assembly →

Pilot Production

Controlled builds used to verify assembly processes, programming, testing, documentation, and material readiness before repeat production.

Repeat Production

Ongoing manufacturing based on the approved BOM, product revision, production quantity, testing requirements, and manufacturing schedule.

For existing products, we can also support second-source qualification and manufacturing transfer to Taiwan.

High-Mix & Multi-Variant Manufacturing

OEM programs may involve multiple PCB revisions, product configurations, BOM changes, or frequent engineering updates.

Our support can include:

Multiple PCB and product variants
