Customer Responsibility
Product design, mechanical structure, brand identity, target market, sales channels, commercial requirements, and agreed accounts or authorizations.
OEM / ODM Cooperation
You define the product and brand. Yuli engineers the solution and manufactures the cold-pressed card
The customer owns product definition, mechanical design, brand, and sales channels. Yuli works to the approved requirements and provides custom hardware and solution engineering, embedded firmware, certification support, pilot builds, and cold-pressed card manufacturing.
We define responsibilities and deliverables before engineering starts. Customers control product appearance, structure, and market strategy; Yuli focuses on electronics, low-power firmware, cold-press DFM, pilot validation, and production.
Responsibility Split
The customer leads the product and market; Yuli delivers engineering and manufacturing.
Before engineering starts, both parties assign ownership for design, documents, ecosystem accounts, and deliverables. Project-specific requirements are recorded in the contract and project files.
Yuli Engineering
Custom hardware, component and power review, antenna and acoustic coordination, embedded firmware, low-power optimization, prototypes, and certification support.
Yuli Manufacturing
Cold-press DFM, PCBA and module integration, room-temperature potting, cold pressing, pilot builds, finished-product tests, and card manufacturing.
Delivery Process
Six stages take approved customer inputs into production.
01
Requirements and Inputs
Confirm product and mechanical files, appearance, ecosystem, functions, volume, certification needs, and schedule.
02
Hardware and Firmware
Develop PCBA, battery, buzzer, button, antenna, and low-power firmware around the approved mechanical space.
03
Prototype Validation
Validate function, power, BLE/NFC, acoustics, buttons, thickness, appearance, and critical reliability requirements.
04
Certification Support
Prepare samples, revisions, and test material for ecosystem or regulatory testing and corrective work. Account and certificate ownership are agreed per project.
05
Pilot Production
Check materials, process, fixtures, tests, appearance samples, and packaging; close pilot issues and freeze the release revision.
06
Cold-Pressed Card Production
Manufacture, test, pack, and release cold-pressed cards against approved drawings, samples, BOM, firmware, and inspection requirements.
Cold-Pressed Card Manufacturing
Room-temperature cold pressing integrates multiple electronic modules into a thin card body.
Yuli cold-press manufacturing integrates PCBA, thin batteries, buzzers, buttons, e-paper, NFC/BLE antennas, biometric modules, and sensors. Selected projects can reduce early product-tooling investment, supporting prototypes, multiple finishes, pilot builds, and production launch.
| Core process | Module integration, room-temperature potting, aligned pressing, finished inspection |
|---|---|
| Integrated modules | PCBA, thin batteries, buzzers, buttons, e-paper, antennas, and sensors |
| Project stages | Functional prototypes, pilot builds, process validation, and production launch |
| Specification control | Thickness, ingress protection, battery life, RF, and reliability follow the product revision and agreed test conditions |
OEM / ODM Customization
The customer defines the product; Yuli turns the form, layout, dimensions, print, and functions into a manufacturable revision.
The customer owns product, mechanical, brand, and channel decisions. Yuli implements the approved requirements through hardware, firmware, cold-press DFM, prototypes, and production launch.
Product Form
Standard cards, e-paper cards, badges, flexible labels, tags, or embedded PCBAs, selected for the intended use.
Layout and Functional Areas
Implement brand graphics, information areas, display windows, buttons, sound ports, indicators, antenna clearance, and coding positions.
Dimensions and Structure
Review length, width, thickness, corners, openings, mounting surface, and stack tolerances, with cold-press DFM updates.
Printing and Finish
Support card graphics, color variants, serials, QR codes or barcodes, and surface finishing matched to the face material.
Firmware Functions
Customize advertising and low-power strategy, button and buzzer logic, pairing, display refresh, sensor sampling, and agreed data interfaces.
Packing and Delivery
Define unit protection, labels, accessories, carton quantity, lot identification, and outgoing sampling for the sales channel and shipping method.
Quotation and Schedule
MOQ, sample lead time, and production lead time follow the project scope.
Standard products, appearance customization, hardware revisions, and new PCBAs require different work. Yuli confirms quotation and schedule from document readiness, materials, functions, appearance variants, certification needs, prototype quantity, and production volume.
Quotation Inputs
Product and mechanical files, functions, ecosystem, appearance, certification, quantity, and required delivery.
Lead-Time Factors
Component supply, hardware revision, firmware scope, prototype rounds, certification tests, pilot issues, and appearance variants.
Production Release
Production is scheduled after drawings, BOM, firmware, samples, tests, packaging, and change rules are approved.
Project Assurance
Define certification and quality response at project start.
Certification support, after-sales response, RMA, and quality handling are defined during quotation, prototype, and pilot stages, then carried into production under the same revision controls.
Certification & Compliance
Confirm ecosystem accounts, applicant and certificate holder, market, test revision, samples, and corrective responsibility.
View responsibility matrixAfter-Sales & Quality
Handle issues by revision, lot, and evidence, with containment, analysis, RMA, 8D, and closure defined.
View response processTesting & Traceability
Link samples, revisions, instruments, environment, raw data, and acceptance results.
