GEM SECS interface | 20 October, 1998

I am looking for detailed information on the SECS 2 protocol that is part of the SEMI General Equipment Module interface. I was not able to get detailed information from the SEMI web site and was not able to find anything on the web.

I am looking for information on the standard to see if and how other SMD equipment can use this to interface with a network.

Weird.

Hey have you tried SMEMA? A lot of board assembly equipment suppliers talk more about SMEMA than SEMI.

Their site is not responding to this above URL, otherwise I'd link ya.

Here is a portion of the description of a course at Georga Tech. The link to the total description is below. Dave F

IE-120 GEM Interface with Applications in Circuit Board Assembly July 28 - 29, 1998

Center for Board Assembly Research (CBAR) Georgia Institute of Technology Atlanta, GA 30332

Course Description

The Generic Equipment Model (GEM) for communications and control from SEMI is rapidly becoming the technique of choice for exchanging information on a circuit board assembly factory floor. Due to GEM�s near �plug-and-play� characteristics, companies are embracing it to lower costs and improve flexibility. Through the GEM interface, processes can be monitored, communication errors handled, and process programs managed in a uniform manner.

The major focus of this course is to introduce the concept, characteristics, and the application of GEM in the context of circuit board assembly. A unique aspect of the course will be the participants� ability to experience Georgia Tech�s state-of-the-art electronics assembly line as shown on the cover. The line is a GEM-compliant, multi-vendor SMT manufacturing facility. The screen output on the right shows an application to monitor a printer, a placement machine, a post placement inspection machine, and an oven.

Specific issues addressed in the course pertaining to GEM include:

What is the SECS/GEM interface? What will the GEM interface do for circuit board assembly? What is the cost/benefit of the GEM interface? What is involved in process control through GEM?

In this course, we will also provide an overview of the Standard Recipe File Format (SRFF). SRFF is expected to become the preferred method for developing process control files. By making use of SRFF, generic program .... bla bla bla

Another excellent source of information is GW Associates. Take a look at their website (www.gwa.com). And no.. I don't work for them!
