Seal Pressure Controls (Figure 2.16)

The sealer mechanism contains two separate

heat shoes which have independent controls

for heat and pressure. The pressure gauges

on the front of the TM-300 indicate the amount

of air pressure in the sealing systems for each

heat shoe. The controls for adjusting this air

pressure are located directly beside the pres-

sure gauges. Turning a control clockwise will

increase the amount of pressure applied to the

associated heat shoe. Normally the two sys-

tems should be set at the same pressure, but

they can be set differently if the seal charac-

teristics dictate that one be set higher than the

other. When taping some very small SMD

components, it may be necessary to decrease

the seal pressure to reduce the shock applied

to the carrier tape when sealing.

Seal Dwell Control (Figure 2.17)

The dwell control selects the amount of time

the heat shoes are in contact with the tape

when the sealer is activated. The dwell time is

always the same for both heat shoes. The dial

on the control reads from .25 to 1.0 seconds in

increments of 0.05. These numbers represent

the actual time the seal heads dwell on the

cover tape. Set the control as shown in the

approximate settings chart for initial set-up.

Experience and peel force tests on sealed

tape will dictate changes from these values.

Attach Air Supply (Figure 2.18)

Connect an air-supply hose (at least 80 PSI)

to the input regulator on the left, rear side of

the TM-300. Slide the air cut-off switch for-

ward to apply air pressure to the TM-300. Pull

up on the regulator control knob and turn it

(clockwise increases pressure) until the gauge

registers 80 PSI. Push the regulator control

knob back down to lock it into position. To

remove air pressure to the TM-300 at any

time, slide the air cut-off switch back.

Operation

Figure 2.19

Figure 2.20

Refer to Figures 2.19 and 2.20 for information

on this page.

Initial Procedures

1. Set the Take-up Reel Adjust control to 0

(fully CCW).

2. Turn the TM-300 main power switch ON.

3. Perform the Taping Assembly Setup pro-

cedures described in this manual.

4. Set the Counter Module Preset and Pres-

cale values.

5. Set the sealer controls at the appropriate

levels. Wait for the temperature controls

to stabilize near their set temperature.

To move the cover tape in relation to the car-

rier, loosen the knob on cover tape guide #3

and pull the guide slightly away from the

adjustment dial so the dial will turn freely.

Turning the dial clockwise will move the cover

tape closer to the sprocket holes on the inside

edge of the carrier (ten divisions on the dial

will move the tape .005 inches).

Turning the dial counter-clockwise will move

the cover tape closer to the outside edge of

the carrier (ten divisions on the dial will move

the tape .005 inches).

Push the tape guide back against the dial after

the adjustment has been made and tighten

the knob. Run the tape out again until the

cover tape stops shifting and check the align-

ment. Repeat this procedure until the proper

alignment has been achieved.

Peel Force

In most taping applications a peel force test is

needed to determine the seal characteristics.

Take as many peel force tests as are needed,

while adjusting the sealer controls, to obtain

the desired seal.

Placing Parts

Starting with the left-most pocket, place a part

in each empty pocket for the full length of the

loading track. Close the parts cover (Fig.2.2,

Ref. Q) if desired. Press on the foot switch to

advance the carrier tape through the taping

assembly. Stop the tape advance prior to an

empty pocket reaching carrier tape guide #2

and refill the carrier tape in the loading track.

Repeat until the trailer has advanced to a posi-

tion where the end of the sealed tape reaches

the take-up reel and attach it to the inside hub

of the reel. Adjust the take-up reel tension with

just enough tension to wrap the tape on the

take-up reel. DO NOT APPLY EXCESSIVE

TENSION. Use only enough tension to wrap

the tape. Adjust tension as needed as parts

are added. Continue taping parts until the

counter module reaches its Preset value and

stops the tape advance.

To End Taping

Preset

When the End Count value on the counter

module is reached, the TM-300 will stop. The

last part to pass under carrier tape guide #2

will be the last part counted. Any additional

parts in the loading track must be removed.

Reset

Press the RST button on the counter module to

enable taping of the leader.

Leader

Seal the desired number of empty pockets.

When the last sealed empty pocket has

cleared the drive sprocket, cut the tape just to

the left of the sprocket.

Operation (cont.)

To Begin Taping

Leader/Trailer

Before beginning a production reel, you must

decide how long the trailer and the leader

need to be.

Trailer - The strip of empty pockets needed

at the end of the reel.

Leader - The strip of empty pockets needed

at the beginning of the reel to feed into a

pick and place machine.

The trailer of each reel is taped first. After the

cover tape alignment and any peel force tests

are completed, run out enough sealed empty

pockets to make the trailer. After the trailer is

taped, check the counter display to ensure it

reads 0. If not, press the counter module

RESET button.

Tape Alignment

To ensure an accurate count, the first pocket

in the loading track (left-most) must be a full

pocket. That is, the left-most edge of the

pocket must be aligned with the right edge of

carrier tape guide #2 (Fig. 2.2, Ref. R). If a full

pocket is not showing, lift the carrier tape free

of the drive sprocket and move it back until a

full pocket is showing, then engage the carrier

tape on the drive sprocket at that point.

Counter Enable

Verify that the COUNTER ENABLE SWITCH

is UP and that the counter has been reset.
