Communication & Optoelectronic

Overview

Propelled by 5G/6G technological evolution, the communication and optoelectronic display industry is advancing toward miniaturization, high‑density integration and high‑speed signal transmission. Optical and photoelectric components are highly sensitive to thermal exposure during soldering, where interconnection quality directly determines signal integrity and long‑term service life of end‑devices.

Core Application Scenarios

• TOSA / ROSA optical modules for optical communication

• RF units of 5G/6G base stations

• Optoelectronic display modules

• High‑density high‑speed communication PCB assemblies

Key Technical Challenges

• Avoid thermal damage to temperature‑sensitive optical components during soldering

• Ensure full compatibility with diverse PCB surface finishes such as OSP and ENIG

• Suppress electrochemical migration to eliminate signal disturbance risks

• Secure consistent mass‑production yield for high‑volume manufacturing
