The Standard Suite to Make SMT Assembly Lines Smarter 

By Junko Collins, SEMI Japan

SEMI has developed “SEMI SMT-ELS (Equipment Link Standards)” the Standard suite for SMT assembly line, which provides a robust universal interface and adds data communication capabilities to make assembly line smarter.

SEMI SMT-ELS uses the advanced general purpose M2M interface SEMI A1/A1.1 for equipment interface tier and uses SEMI A2 "SMASH" (Surface Mount Assembler Smart Hookup), which was proposed by SMT assembly equipment suppliers for the SMT assembly line control tier.

SEMI Standards are global standards that have been supporting semiconductor and related manufacturing lines for many years and this new standards suite will expand the industry coverage of SEMI Standards.

Benefits of SEMI SMT-ELS
SEMI SMT-ELS provides higher level of connectivity and control capabilities for 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 future requirements.

Prototype Exhibition of SEMI SMT-ELS
In order to deploy SEMI SMT-ELS Suites to SMT industry, the special exhibition, so-called "SEMI SMT-ELS Special Exhibition" was held at electronics assembly technology exhibition JISSO PROTEC in June and NEPCON ASIA in August this year. The placement equipment provided by leading suppliers were connected and performed the demonstration of automated product setup using various sized panels (PCB substrates). This demonstration attracted the attention of many people.

By the success of this exhibition, it is widely recognized that the intelligent connection between different types of equipment can be performed smoothly using the SEMI SMT-ELS Suite.

SEMI Standards used for SEMI SMT-ELS

SEMI SMT-ELS consists of the following SEMI Standards:

  • SEMI A2, Specification for Surface Mount Assembler Smart Hookup (SMASH)
  • SEMI A1, Specification for Horizontal Communication (HC) Between Equipment for Factory Automation System
  • SEMI A1.1, Specification for Media Interface for A Horizontal Communication (HC) Between Equipment

Published Standards are available online for individual purchase or through SEMIViews. SEMIViews provides easy online access to the complete library of more than 1000 SEMI Standards. Contact SEMI Staff in your local region on how to purchase SEMIViews. To inquire about Standards being revised and activities currently being developed, please join SEMI Standards activity below.

SEMI Standards Standardization Activity
The SEMI Standards Automation Technology (AT) Technical Committee is responsible for development and improvement of these standards, and task forces under the committee are responsible foreach document. The activity is open for everyone with free Program Member registration.

SEMI Standards Application Activity
The SEMI FlowManufacturing (FM) Forum is open to any users and suppliers of the SEMI SMT-ELS Standards suite who are interested in learning how to apply these Standards.

Participation and Endorsement
The following companies are actively participating in SEMI standardization activities and endorse the application of the SEMI SMT-ELS Standards suite.
