SEMI_SMT-ELS

“SEMI SMT-ELS (Surface Mount Technology - Equipment Link Standards)” is the Standards suite for SMT assembly line that provides a robust universal interface and adds data communication capabilities to make assembly line smarter. 

SEMI SMT-ELS Standards suite uses the advanced general purpose equipment interface "SEMI A1/A1.1 PESCI (Production Equipment Smart Connection Interface)" for equipment interface tier and uses “SEMI A2 SMASH (Surface Mount Assembler Smart Hookup” that was proposed by major SMT assembly equipment suppliers for SMT assembly line control tier.

SEMI Standards are global standards that have been supporting semiconductor and related manufacturing lines for many years and its development process is open for those who are interested.

SEMI SMT-ELS provides higher level of connectivity and control capabilities of SMT assembly line including:

• Host-equipment Communication
  • M2M Network setting
  • Production route setting
• Inter-equipment Communication
  Direct communication between equipment which performs:
  • Immediate product change
  • Panel Data usage mode setting
• Panel and Panel Data Transfer
  Object Oriented panel transfer which simultaneously transfers a panel with its data.
  • On Demand product change
  • Panel handoff exception handlings (Pause ? Recovery)

SEMI SMT-ELS is highly extendable in its structure for the future requirements.

SEMI SMT-ELS consists of the following SEMI Standards.

• SEMI A2          Specification for Surface Mount Assembler
                           Smart Hookup (SMASH)
• SEMI A1          Specification for Production Equipment
                           Smart Connection Interface (PESCI)
• SEMI A1.1       Specification for TCP/IP Interface for PESCI

Published Standards are available through “SEMIViews” the license to access those documents. Please ask SEMI Staff in your locale for SEMIViews.
