Figure 4-61: Tape Output Module Controller. The arrow points to the

Power On/Off button which is also the Emergency-Stop.

3b. Configure the Tape Output Controller by setting the following:

At the Setup menu:

•reset Count Stop to desired amount:

Press 1, to re-zero the present count

Press 2, then enter the desired number, then press the ENT but-

ton.

• select the desired device tape pitch from the Pitch Selection

menu. Then press ENT.

Note: The pitch can be determined by using the pitch setting decal

located on the loading track or the pitch setting guide found at the

front of the TM-50 Taping Module User’s Guide.

At the Advance menu:

• set the number of pockets to advance to 1. Then press ENT.

At the Speed menu:

• set the advance speed between 40 to 100 depending on the

device tape width and device size. Then press ENT.

Note: Prevent device tape breakage and advancement problems

with small devices and narrower tape widths by setting slower

speeds— in the range 40 to 60.

Higher speeds may cause the devices to be dislodged from the pock-

ets or may cause the sprocket holes on the tape to rip out.

For more information,

Module Users Guide

that came with your

equipment.

back

At the Jog menu

• jog the device tape forward to align the pocket with the

PNP head.

At the Mode menu

• select PSA mode for pressure seal cover tape. An asterisk indi-

cates the current setting. Then press ESC.

Note: The Heat Seal switch should be OFF.

At the Run menu

•select Run Mode. The run window displays all the selected setup

parameters.

• verify all settings for accuracy.

4. Inspect the PSA Seal Rollers (cover tape rollers)—

4a. Inspect the seal rollers for build up of adhesive from the cover

tape. See Figure 4-62.

Figure 4-62: On the Tape Out Module, the PSA Seal Rollers (arrows)

and Sprocket Idler with O-rings.

5. If adhesive buildup exists on the PSA Seal rollers—

5a. Using a shop towel and alcohol or alcohol wipes, clean the adhe-

sive build up from the cover tape application rollers. Hold the

alcohol cloth on the roller and rotate the roller 360°.

5b. Repeat procedure for the other application roller.

6. Inspect drive sprocket idler and rubber O-rings—

6a. Inspect the drive sprocket top idler and rubber O-rings for any

build up of adhesive from the cover tape. See Figure 4-62.

7. If adhesive buildup exists on the idler and O-rings—

CAUTION: O-rings might be easily damaged. Handle gently to

avoid breaking them.

back

7a. Gently remove the two O-rings from the drive sprocket idler.

7b. Using a shop cloth and alcohol or a commercial alcohol wipe,

remove all adhesive from O-rings.

7c. Wipe the idler clean.

7d. Reinstall the dry O-rings onto the idler.

Adjusting Pressure of the PSA Seal

Rollers

1. Advance the device tape with the cover tape through the Seal

Rollers using the manual advance pedal. Advance enough pock-

ets to correctly align the cover tape on the carrier tape.

2. Perform a peel back test by peeling the cover tape from the carrier

tape. Notice how well the cover tape adheres to the device tape.

Perform a twist test by giving the tape a slight twist. Notice if the

cover tape detaches from the device tape.

If either test produces loose cover tape, increase the application

roller pressure by screwing the PSA Seal pressure adjustment

screw in (clockwise).

If both tests look acceptable, visually inspect the sealed device

tape for adhesive that may have been squeezed out during

application. If adhesive is visible, the Seal Roller pressure is too

high. Decrease the application roller pressure by screwing the

PSA Seal pressure adjustment screw out and retest.

Troubleshooting the Tape Output

System

The Tape Output System contains sensors that detect these fault con-

ditions:

• a device is on top the device tape (carrier tape)—Track Jam Sen-

sor

• no cover tape is on the reel—Cover Tape Sensor

• device tape is not properly inserted in the device tape

track—Device Tape Present Sensor

• a pocket in the carrier tape is empty—Pocket Empty Sensor

When the AH500 software displays the error message Tape Out Unit,

one of the tape output system sensors has been triggered. The most

likely sensors to trigger are the Device Jam and Device Tape sensors.

See Figure 4-63.
