Factory audit guide

How We Build LED Displays

A useful factory review connects what you see to your purchase order. The checkpoints below show what to inspect and which records to retain before shipment.

Six checkpoints

Follow the order through production

Exact equipment, tests and acceptance limits must be confirmed for the selected product and written into the order documents.

Supplier and material intake

Verify: Approved supplier or declared source, part number, lot identity, quantity and incoming inspection status.
Retain: Purchase-order-linked material list, labels, incoming inspection record and nonconformance disposition where applicable.

PCB assembly

Verify: Process route, component placement, soldering controls and the inspection method used for the selected module.
Retain: Line walkthrough, work instruction, first-article approval and in-process inspection record.

Module and cabinet assembly

Verify: Module alignment, connectors, cable routing, grounding, service access and cabinet identification.
Retain: Approved drawing, assembly checklist, labelled cabinet photos and configuration record.

Functional and aging test

Verify: Test duration and conditions agreed for the order, displayed patterns, power cycling and treatment of failed units.
Retain: Order-specific test plan, start/end records, photos or video and rework/retest record.

Calibration and final inspection

Verify: Visual uniformity, dead-pixel criteria, brightness or colour measurements when specified, control-system setup and accessory count.
Retain: Final inspection report, measurement files where contracted, configuration backup and signed exception list.

Packing and shipment release

Verify: Packing method, labels, serial or batch references, spare parts, cables, manuals and shipping marks.
Retain: Packing list, packed-goods photos, shipment release record and third-party inspection report if commissioned.

Buyer checklist

Questions to ask during a live audit

Which legal entity signs the sales contract and which facility performs each production step?
Which parts of this order are subcontracted, and how are subcontractors controlled?
How are materials and finished cabinets linked to the purchase order or batch?
What happens when an inspection fails, and can the buyer see the rework and retest record?
Which final checks are performed on every unit and which are sampling checks?
Can an independent inspector attend the agreed pre-shipment acceptance?

Define acceptance before production starts

Send the target model, quantity, destination, inspection scope and any tender requirements. We can prepare an order-specific evidence checklist for review.
