About

The ADT 7100 Dicing Saw is optimized for multi-angle dicing of thin, tight tolerance products up to 200 mm x 200 mm. It is currently setup for dicing up to 8” diameter wafers. Check the Dicing Saw Recipes page for the blades we currently stock.

Detailed Specifications

Operating Procedures

Install Your Blade and Flange

Right click on the blade icon in the lower left corner of the screen and select 'Blade Change'.

Open the dicing saw cover and place the interlock defeating key in the door interlock.

Grab your blade/flange (with the grabbing tool or hand) and CAREFULLY place it onto the spindle. This should require very little force. If the flange doesn't easily slide onto the spindle please contact me immediately.

Once you have installed your blade and flange onto the spindle you must secure it with the lock nut. To do this, line up any of the two holes on the lock nut with the two pins on the two piece torque wrench tool. Hold the back part of the wrench in place with one hand and turn the front part of the wrench clockwise with the other hand. Once the lock nut is hand tight you'll have to crank on the torque wrench until you hear a click. That should be the appropriate amount of torque to keep the flange on the spindle.

From the 'Blade Selection' drop down menu, choose blade you just installed. If you are using a different flange diameter from the one selected in the software click the 'Change Flange' box and manually enter in the new flange diameter. Click 'Done' and then click 'Finish' in the lower left dialogue box.

DO NOT STICK YOUR HANDS INTO THE SYSTEM! The saw will eventually start to rotate and go through its blade exposure measurement sequence.

Once it says 'Blade change completed' inside the dialogue box you can check the three water sources.

Adjust the Cut Water

BE EXTREMELY CAREFUL! The spindle is still rotating! Carefully pull the spindle cover lock to the left and open the spindle cover.

Press the 'Water Adjust' to turn on the three different water sources. Verify that the Cut water is being forked by the blade (you should see a stream of water in front of the blade and one behind it). The Cut water should be hitting the blade/flange at approximately 7pm if the blade was a clock. If adjustments are needed, you can move the Cut water nozzle by holding the knob behind the nozzle with one hand and turning the top knob above counter clockwise. This will unlock the Cut water nozzle and give you free range of motion. Make sure you do not rotate the Cut water nozzle up into the blade! Once the Cut water looks good you can lock it in place by turning the top knob clockwise until it's tight.

Verify that the flow rates of the Cut water, Clean jets, and Spray bars are 0.9 LPM, 0.8 LPM, and 0.8 LPM respectively. You can turn down the flow rates by adjusting the three small regulator knobs below the computer monitor. Just make sure to return the flow rates to their default values before ending your dicing session.

Once the water situation looks good you can right click on the spindle speedometer in the top right of the screen and choose 'Operate'. This will turn the spindle off. Once the spindle has reached 0 RPM you can pull the interlock key and close the dicing saw cover.

Initialize System

After your initial blade change you must go to User =>System Init. This will initialize the chuck and saw and get the system ready to accept your sample.

Once, the screen stops flashing yellow you can choose one of two routes. You can either create or load a recipe or load your sample.

Create a Recipe

To create a recipe, click on the book icon (Programming Workspace). In order to create a recipe in the software you must duplicate an old recipe. You can either duplicate a group/company member's recipe or open the 'RECIPES' folder on the left hand side of the software and select 'Recipe_APC'. Click 'Duplicate Recipe' and create a recipe name. Make sure you save your recipe in any other folder besides the 'RECIPES' folder. You can either find your folder by using the drop down menu or you can create a new folder name by typing into the 'Folder' box.
