Pre-production Quality Control

Component Inspection

All incoming LEDs, drivers, and passive components undergo 100% visual inspection and electrical parameter verification to confirm authenticity and performance specs before they enter the production line.

Solder Paste Inspection (SPI)

We perform automated solder paste inspection to verify precise application on every pad — ensuring consistent volume, proper alignment, and minimal defects before component placement.

First Article Inspection (FAI)

Before full production runs, we build and test the first assembled modules against your complete specifications — verifying dimensions, electrical performance, and light output to confirm the process is right before scaling up.

Our Production Overview Of LED Module Assembly

We maintain a fully equipped SMT and assembly line dedicated to LED module manufacturing — ensuring precision, consistency, and capacity for orders of any size.
