Description

In keeping with our tradition of building handlers for almost any device that comes along, Exatron introduced SIMM/DIMM handling in our product line a few years ago. At first, we confined the SIMM/DIMM handling to the Model 3000B and 3000BL line of handlers. As the types of SIMM/DIMM have increased, so too has our line of SIMM handlers.

Exatron now offers several types of SIMM/DIMM handlers, including 3000B bulk output systems, 3000B tray output systems, 3000BL labelling systems, and 5000 tray output systems designed for very large test heads like the HP 84000 test system.

In addition to our more extensive choice of handling systems, we now offer a wide variety of contactor choices for various size SIMM/DIMM modules, including a line of high-speed SIMM/DIMM contactors, good out to 250 MHz.

Operation

The Exatron SIMM handlers have been designed to run a wide variety of SIMM/DIMM modules in various pin counts and various IC populations. SIMM handlers are available with a label application option (3000BL base only) and with bulk or tray output options.

Exatron SIMM/DIMM handlers come with a "magazine" input that is hand loaded with modules. The magazine holds (nominally) 102 devices. The real capacity of the magazine depends on the length of the modules themselves. The tracks are 25.5 inches in length and there are seventeen tracks in a magazine. The magazine is easily adjustable in height to accommodate different modules.

Modules are singulated at the output of the magazine and then slide into the test site. Exatron offers metal pin-based or Particle Interconnect-based (High Speed) contactors in different pin counts and pitches for different modules.

If the system includes a label applicator, the modules then slide into the label site. The modules are tipped over and then held against a hard stop to keep the modules square in the label site.

Following the test (and labelling, if applicable), the device is sorted on a pass/fail basis only. The 3000B SIMM is offered with bulk output or with shipping tray output options. If bulk output is chosen, then the parts are dropped into bins of pass or fail devices. The 5000 base system is available with a dual tray loading option -- operators can mount a fresh tray while the machine is filling the other.

If the tray output option is installed, then the pass modules will exit into an output arm held over the slots of a pre-formed tray. The tray itself is loaded onto a motorized platform which moves across the system under the output arm. When empty slots are under the arm, the arm opens to allow the modules to fall into the output tray.

In any case, the 3000B SIMM/DIMM handler is controlled by a standard Exatron controller with standard diagnostic routines and control programming.

Options

Upgrade to Automatic Print and Apply Labeller
Exatron offers a generous trade-in program in the event the customer wishes to upgrade their Model 3000B-SIMM to a Model 3000B-Labeller-SIMM.
Opto-isolation Interface
Exatron offers an opto-isolation interface option for electrically "noisy" applications.
Light Pole Status Indicator
Exatron offers a three-color light pole status indicator to provide quick visual updates on handler performance to operators.This facilitates operation of multiple pieces of equipment by single operators.

Contactor

Exatron SIMM/DIMM handlers use one of two types of contactors: High Speed Particle Interconnect contactors or metal finger contactors. The choice of which sort to use depends on a number of features, including pin count, pin design (straight line v. staggered), functional requirements, etc.

Our High Speed SIMM/DIMM contactors have been independently tested to 250 MHz and are available in a variety of sizes. Custom sizes are available upon request.

In addition to automated test sites, Exatron offers manual test sites for e ngineering purposes. These manual test sites use the same contactors as the automated sites, so engineers can develop tailored test programs off line and then transfer these programs to the production floor with minimum trouble.
