The Model 3000B
with Eight Automatic Inputs

XATRON

eight-tube Octoloader is an ambient automatic eight-tube loader. The standard Model 3000B
comes equipped with this octoloader which is a moving metal plate holding up to eight tubes of devices,
controlled by the handler's CPU by means of a stepper motor. The plate automatically moves both left
and right, positioning each tube of devices over the handler input track. When the input track is emptied,
the octoloader automatically searches for tubes with devices. The octoloader has a sensor mounted at its
junction with the input track. The octoloader can "see" a device jam and stop its own movement to
prevent breaking the jammed device. The octoloader also has an automatic "wiggle" jam-clearing
operation which it will implement immediately in an effort to remove the jam without operator assistance.
Model 3000B octoloaders use a Snap-On plate which is specifically fitted with tube holders for a given
device application.
All Model 3000B Handlers not intended to be used on a "FRED," (Free Rolling E
XATRON
Dolly) are
supplied with bench-top base plates which must be bolted directly to a bench or table top to secure the
handler. Each plate includes two sets of tilt bars which enable the handler's tilt angle to be altered for
specific applications. The tilt angle is critical for ceramic DIPs and LCCs since too much drop angle may
cause chipping of the packages.
The Model 3010B
with One Elevated Temperature Track
The Model 3010B Hot Rail adds a single track hot rail to the input of the handler. This track holds twenty
inches of devices in order to preheat them prior to test. The temperature range of the Hot Rail is ambient
to +125
°
C. AC heaters are located within the Hot Rail. Exceptional temperature control is maintained by
constantly monitoring four points in the Rail and four points in the Test Site. The guaranteed accuracy is
±
3
°
C everywhere in the Soak Rail and
±
2
°
C in the Test Site. All four "zones" in the hot rail are
controlled by an E
XATRON
-designed computerized temperature controller.
The input of the Hot Rail has a manually operated two-input tube holder assembly.
All Model 3010B Handlers are supplied with a Free Rolling E
XATRON
Dolly ("FRED.") For operation, the
handler is to be mounted onto this floor stand which has four large tires for easy positioning and four floor
jacks to lock it into place.
