• Dust-free areas for optical bonding (if applicable)

• Adequate warehouse space for material and inventory

• At least 2,000–3,000 sqm for efficient output

Quality Control Processes

A professional supplier should implement strict QC standards, including:

• Incoming Quality Control (IQC)

• In-process Quality Control (IPQC)

• Aging and burn-in testing (8–24 hours)

• Final Quality Control (FQC)

• Reliability testing (vibration, high/low temperature, drop tests)

A factory willing to provide production photos, videos, or virtual audits shows transparency and reliability.

4. Confirm Quality Certifications and Compliance

Certifications are one of the clearest indicators of a supplier’s professionalism. Industrial buyers should look for internationally recognized certifications, including:

• ISO9001 Quality Management System

• ISO14001 Environmental Management

• CE, FCC, RoHS for global compliance

• EMC and safety testing reports

• UL or ETL (if targeting North America)

Certifications ensure that the supplier follows standardized processes and that the hardware meets regulatory requirements for exporting to Europe, North America, and other markets.

Tip: Request digital copies of the certificates to verify authenticity.

5. Review Component Quality and Supplier Network

Industrial displays and PCs must run reliably 24/7 in harsh environments. This means that component selection is crucial.

Important components to review:

• Touch panel brand (G+G, P+G, industrial-grade sensors)

• LCD panel supplier (BOE, Innolux, AUO, LG, etc.)

• Motherboard components (industrial-grade capacitors, long-life CPUs)

• Power supply units (certified and stable)

• Cooling design (fanless aluminum alloy)

• Connectors & I/O (Phoenix terminals, industrial M12, dual LAN, RS232/RS485)

High-quality suppliers will clearly list their component brands and provide a BOM (Bill of Materials) for OEM/ODM projects.

6. Assess Customization Capabilities (OEM/ODM)

Industrial projects often require customization. A qualified OEM supplier should support a wide range of hardware and software modifications.

Common OEM/ODM Capabilities:

Hardware Customization

• Custom housing (color, logo, branding)

• Custom I/O ports (RS232, GPIO, CAN bus, POE, Phoenix terminal)

• Special mounting options (VESA, panel mount, open frame)

• Wide-temperature operation (-20°C to 70°C)

• IP65 or IP67 front panel protection

• High brightness LCD (1000–1500 nits)

• Optical bonding

• Special materials (metal, aluminum alloy, stainless steel)

Software Customization

• Android OS customization (UI, boot logo, kernel-level changes)

• Windows or Linux driver adjustments

• BIOS settings and security lock

• Pre-installed applications

• Kiosk mode configurations

Strong customization capability differentiates real OEM factories from simple trading companies.

7. Evaluate Communication Efficiency and Professionalism

Communication is often overlooked, but it is one of the strongest indicators of a reliable OEM supplier.

Signs of a good supplier:

• Fast replies (within 24 hours)

• Clear and professional documentation

• Experience dealing with international customers

• Ability to provide full technical drawings promptly

• Transparent explanations about cost and production timeline

Good communication significantly reduces project delays and misunderstandings.

8. Review MOQ Requirements and Flexibility

OEM projects may begin with small trial orders. A good supplier should offer:

• Low MOQ for customization

• Sample orders for testing

• Flexible pricing for different volumes

• Clear terms for prototype → mass production transition

Factories with very high MOQ requirements may not be ideal for emerging or fast-testing projects.

9. Inspect Lead Time and Supply Chain Stability

A supplier’s delivery speed directly affects your delivery commitments to your customers. Evaluate:

Important lead time considerations:

• Sample lead time (usually 7–15 days)

• Mass production time (15–30 days depending on complexity)

• Material stocking levels

• Ability to handle large orders

• Stability during global component shortages

Good suppliers usually maintain strategic inventory of CPU boards, LCD panels, touch modules, and metal housings.
