Surface Mount Technology (SMT) Manufacturing and Process Challenges

COURSE OVERVIEW

The goal of greater functional integration is impacting both SMT assembly and IC packaging with technological and manufacturing challenges. Numerous package styles, multi-chip packages and 3D packaging approaches are changing the face of traditional SMT assembly. The growth of packages involving multiple dies on organic substrates has brought SMT processes into the realm of the packaging industry. SMT know-how is being rapidly adopted by the backend process in the manufacturing of MCMs and SIPs, custom packages and specialty modules. This seminar combines the basic to intermediate level of such packages and its manufacturing guidelines for SMT as well as backend and SMT hybrid assembly.

The following critical materials applications will be covered:

  • SMT History and Process Overview
    How SMT came about and what are the advent and technological advancements in the SMT components and manufacturing complexities.
  • Solder Paste, Screen Printing and Adhesives
    Solder Paste Rheology and solder paste particle size and printing technology (stencil design and printers) are shaping the new era of SMT technology towards super
    miniaturization and hybrid assembly.
  • Pick and Place (P&P)
    How pick and place technology is reshaping the cycle time, floor space and machine utilisation together with ROI. Multiple axes as well as IOT combined pick and place is key today
  • Soldering and the Reflow Process
    The metallurgical and chemistry aspects of solder paste play a critical role is shaping and forming a good solder joint. Different heat transfer and flux classification with respect to solder paste is also key as well as thermal profiling.
  • Cleaning Criteria
    Often SMT hybrid would require the cleaning process and we will touch-base on the different cleaning technology and chemical suitable for hybrid SMT.
  • Rework Methodology
    Rework would be allowable for 0603 chip and above and also for only micro-
