Ever wondered how to inspect the micro-structure of smartphone speakers?

As the core acoustic component of mobile devices, smartphone speakers rely on precision micro-welding and assembly to deliver Hi-Fi sound in ultra-slim designs. Their performance & lifespan depend entirely on coil weld quality, magnetic coating uniformity, and component fit accuracy.

Check out our metallographic sample prep workflow for crystal-clear micrographs:

1️⃣ P180 SiC disc → Grind to target edge

2️⃣ P400 resin-bonded diamond disc → Finish grinding to target area

3️⃣ POS disc + 9μm PD-WT slurry → Fine grinding

4️⃣ SC-JP cloth + 3μm PD-WT slurry → Rough polishing

5️⃣ ET-JP cloth + 0.05μm AO-W alumina slurry → Final polishing

Elevate your consumer electronics quality control with Trojan’s metallographic solutions!
