All four factors may be varied on the TM-300

but only the dwell time, seal pressure, and

temperature setting changes are usually

required. The seal width is selected at the fac-

tory and should only require changing under

unusual circumstances. The settings in the

chart are good general starting points to be

used when first learning to use the TM-300.

Experience will suggest variations from these

settings that will provide the desired seal char-

acteristics as determined by a peel force test.

Setup (cont.)

General Seal Setting Information

The cover tape peel force is determined by

four things at the time the cover tape is sealed

to the carrier tape.

These four factors are:

1. The width of the sealing track on the

heat seal shoe.

2. The pressure applied to the seal area.

3. The dwell time, or heating time that the

heat shoe is pressing on the cover tape.

4. The temperature of the seal assembly.

Approximate Starting Points for Seal Controls

***Use this chart as a guide for setting the controls for the first time. These values may need to

be altered due to variations in lot materials and customer requirements.***

Setup (cont.)

Temperature Controls (cont.)

Increment Key (Ref. E)

When pressed, increases the set temperature

value. Successively increases the value when

held down.

Decrement Jey (Ref. F)

When pressed, decreases the set temperature

value. Successively decreases the value

when held down.

Return Key (Ref. G)

Each time pressed, changes the readout on

the main display as shown in Figure 2.15.

Present Data Indicator (Ref. H)

“SP” lights while the set temperature is dis-

played.

Setting the Temperature Controller

1. Press the Return key until the “SP” inicator

lights.

2. Adjust the value by pressing the ( )

or ( ) keys until the desired set temper-

ature is displayed.

3. Press the Return key again to display the

current temperature.

There is one temperature controller for the

inside heat shoe and one for the outside heat

shoe. Normally the two controllers should be

set with the same values, but they can be set

differently if the seal characteristics dictate

that the one controller needs to be set higher

than the other.

Error Messages

If there is a fault (short or open) in the temper-

ature sensor (thermocouple) of the sealer, the

display will flash “ “ or “ “. This

error message will also be displayed if there is

no sealer connected to the TM-300.

Temperature Controls (Figure 2.14)

Led Deviation Indicator (Ref. A)

The ( ) indicator lights when the current tem-

perature is higher than the set temperature.

The ( ) indicator lights when the current tem-

perature is lower than the set temperature.

The ( ) indicator lights up green when the

current temperature is within the steady state

range of the PID cycle.

Main Display (Ref. B)

Sequentially displays the present temperature,

set temperature, and an alarm value each

time the RETURN key (Ref. G) is pressed.

Control Output Indicator (Ref. C)

Lights while the control output is being pro-

duced.

Alarm Indicator (Ref. D)

If the present temperature exceeds or falls

below the set temperature, by the alarm value,

this indicator will light. This feature is not

implemented on the TM-300 Controller.

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.
