3.8 Feeder modules for E by SIPLACE
Key properties of the SIPLACE SmartFeeder E include the high precision of the pickup position,
online programmability, a LED status displays and simple handling for feeder module changes
during the placement process. The power supply and the machine communication to the feeder
modules uses Pogo-pins.
3.8.1 Tape feeder modules
3.8.1.1 Tape material
The possible tape widths range from 8 mm to 56 mm. The tape material is blister or paper. The
design of the tape feeder modules was based on the following tape standards:
DIN EN 60286-3 (12/1998) / IEC 60286-3 (12/1997)
JIS C 0806-3 (1999)
ANSI/EIA 481-C (10/2003)
IEC 60286-3-2 3
The overall height of the blister tapes depends on the tape width, and must not exceed the follow-
ing maximum values:
For 8 mm paper tapes, the paper thickness must not exceed 1.6 mm.
3.8.1.2 Tape reel diameter
The tape reel diameter may be up to 19" (483 mm) for all feeder modules.
