AI Technical Summary

Technical Problem

Existing SMT carriers cannot stably control the expansion and contraction rate of FPCs, resulting in solder paste printing misalignment and component misalignment. Furthermore, they cannot accurately measure the FPC shrinkage rate in one go, leading to carrier waste and production defects.

Method used

A carrier structure including a base, a fixing post, a boss, a limiting part, and a cover is designed. The fixing post and the boss fix the position of the FPC, the limiting part fixes the components, and a high-temperature resistant magnet is used to stabilize the relative position of the FPC and the components. The base is provided with a machining part to accommodate the expansion and contraction of the FPC, and the cover covers and fixes it.

Benefits of technology

It improved production efficiency, reduced carrier scrap, increased solder paste printing and SMT yield, and ensured the stability of component positioning.
