Description

Productivity can be further en-

hanced by knowing exactly the

current condition and utilization

rate of the system, about idle

times which occur and their

causes. This information is sup-

plied by ”production and machine

data acquisition systems”

(PDA/MDA). The SIPLACE Ma-

chine Data Management System

collects all relevant data for the line

and individual stations and pres-

ents it graphically. The data in-

cludes analyses of availability, pick-

up error rates, placement speed,

MTBF and MTTR as well as for

track error display with component

item number and package form

number. This speedy, clear view of

the operating behavior provides

starting points for possible im-

provements.

Configuration of a Production Line with GEM Computer

Description

The function of Semiconductor

Equipment Communication Stan-

dard (SECS) II is to uniformly de-

fine communication interfaces of

production equipment made by

different manufacturers. It was fur-

ther developed into the GEM

Standard (General Equipment

Model) which is also suitable for

SMT production equipment. In this

case, an external user-specific

production computer (host) is con-

nected via LAN to a GEM com-

puter integrated into the machine

control. The interface is used by

host systems created by the user

or applications software from third-

party manufacturers.

The SECS II / GEM communication

protocol supports central control,

process control and their data

management of complete produc-

tion lines on the line computer.

Using Statistical Process Control

(SPC), for example, it is possible to

implement preventive mainte-

nance which prevents or greatly

reduces production down times.

The product Remote Support en-

ables online access to the line

computer, station computer and

machine controller of SIPLACE

placement systems from the sup-

port centers in Munich, Norcross

and Singapore. The SIPLACE ex-

perts in the pertinent support cen-

ter can employ remote data and

the program files of the individual

SIPLACE lines in Production to an-

swer all questions about the

placement systems, immediately

and online.

Remote Support is offered on the

basis of communication via ISDN

(Integrated Services Digital Net-

work). Due to its high data trans-

mission speed (64,000 or 128,000

bits/s) ISDN is an ideal medium for

high-speed transfer of large quanti-

ties of data, the SIPLACE expert at

a “Remote Support Position”,

which consists of one line com-

puter, one station computer and a

communications router, can log

himself or herself into the corre-

sponding computers of the

SIPLACE line in the customer's

plant. Remote Support positions

are available in Munich, Norcross

and Singapore. An ISDN router is

also installed at the SIPLACE or

site LAN of the customer. There

need be only one such router per

production facility, however, if the

lines at the customer's site are in-

terconnected via a site LAN.

Basically, the same functionality is

available via Remote Support as is

possible at the local computers

(line computer, station computer

and machine controller).

To comply with the customer's

need for security where sensitive

production data are involved, many

mechanisms (automatic callback,

password protection, switch-off

mode, etc.) are integrated into the

system and can be applied specifi-

cally.
