INSTRUCTIONS FOR L3010/20/60
PAGE 1 - REV. L
Punch Installation and Set-Up
NOTE: Unless otherwise specified, reference Punch Kit drawing 20001084-312 and Bill of
Materials 20001084-015 or 20001084-016.
NOTE: All adjustments are Pre-set at the factory, but due to shipping and handling, adjustments
may be altered. Allteq suggests that a quick check of theses adjustments be made to
insure proper operation of Punch.
NOTE: If punch assembly is installed and Punch is out of adjustment, refer to Page-3, “The 7
Steps to adjusting the Punch”, only after the correct leadframe and punch parameters
are programmed.
1) Turn off machine; disconnect power, and air source.
2) Remove Microscope Mount and left top and bottom cover.
3) Open Rear Panel Assembly, this will help to install item-15. Route through rear center plate
and connect to Program Panel’s PCB 30001017-420 (See BOM and Page-6).
4) Remove block-off plates from position 2 and 3 on air manifold (See Page-6).
5) Remove dowel pins, flat head screw and discard (See Page-7).
6) Install Bias-Solenoid Assembly, item-2 and Ty-wrap cable accordingly. NOTE: Remove item
1 to mount Bias Solenoid Plate, item-8 (See Page-7)
7) Install items 3,4,5,6,13, and 15 (See BOM and Page-6, for schematic and pneumatic
connections and).
8) Remove Rear-Rail Assembly and mount Punch Assembly to Rear-Rail Assembly using the
set of holes closest to Rear-rail and making sure the Punch is Square or 90 (Degrees) to
Rear-Rail Support Bar. Finally make sure Punch Assembly is centered in Rear-Rail slot and
mount item 3, Drip Tray (See Page-8).
9) Install Rear-Rail Assembly back onto machine, connect ALL tubing’s and cable’s. (See
Page- 6).
10) Turn on machine.
At this time, the machine does not know if there is Brush installed on the machine. To activate
the Brush, push the “MODE SELECT” key, then clear the existing mode and enter mode “910”.
Press the enter key until the display is shown below:
NO Rework/Reject ID Selected. Use MD key
To Change or NEXT/ENTER key to Continue
PAGE 2 - REV. L
This asks if the machine has one or more of the optional Rework/Reject Identification
mechanisms. The seven (7) possible ways of identifying Rework and/or Rejects. If your unit is
NOT equipped with any DID (Defect Identifiers), the machine will show the display above.
To activate any of these options, press the “MD” key to select the DID (Defect Identifier) you
want to use or “NEXT/ENTER” key to continue through the menu. You may exit this mode by
pushing the "MODE" key. If the “MD” key was selected, display will be as shown below:
DIDs (1)L/Pn (2)H/Pn
(5)B/Sc (6)T/Ik (7)B/Ik;
(3)W/Br (4)E/Mk
CLEAR Changes
If none of the numbers is flashing, the machine had never been programmed to have any DIDs
or they have been deactivated. The available options are as follows; Brush with Top or Bottom
Inker, Punch with Top or Bottom Inker or Punch or Inker with Edge Marker. To select a DID,
push the “CLEAR” key. For example, if the Puncher is installed on the machine, pressing the
“1” key will select that option and number will flash and any other DID that can be used with it.
To only select ONLY the Puncher, push the “ENTER” key, at this time the display will be shown
below: To exit, push the “MODE” key. At this time the DID will go to it’s home position. If it
doesn’t, turn off machine and check all cable connection. (Refer to 20001084-312)

NOW HOMING THE DEFECT POSITIONING MOTOR
The machine has a working Home Sensor.
The following steps are the “Mechanical” and “Calibration” setup.
11) There are “7” steps to setting up the Punch, are as follows, Flag adjustment, Speed of Carm (up/down), Z-Height adjustment, Shock Absorber Height, Bias Solenoid adjustment,
Punch Sleeve Assembly Speed (down) and Punch Calibration using Mode 998.
12) To adjust PUNCH FLAG, turn off machine and loosen item-1 then turning item 2 clockwise
approximately in 1/4-inch increments (See Page-9). Turn OFF and ON machine,
PAGE 3 - REV. L
adjustments are made when Punch C-arm is even or level with Rear-Rail front edge. (See
Page-8)
(NOTE: THIS ADJUSTMENT MAY TAKE SEVERAL ATTEMPTS).
13) With the machine turned ON, press the “MODE” key and clear existing mode. Enter “920”,
press (2)Indexer, press (2)Move Right and hold down key until Gripper Finger Assembly is
all the way to the right side of Conveyor. At this time a flat/straight " DUMMY " leadframe will
be used. Set the rail spacing to the proper leadframe width. Slide leadframe into rails from
the left side of Conveyor and disconnect item 13 (See Page-9) of Punch Kit drawing and
manually slide Punch Assembly forward to the middle area of rails. Slide leadframe over the
area where punching will take place, either in the "Y” or "X" position leads (See Page-13).
14) Next step to press (3)DONE, press (3)SOLENOID and press (2)FRAME BIAS, this will
pneumatically Raise and Lower Z-Height of PUNCH Assembly. To adjust the Up and /Down
speed, use item 9 (See Page-9) which adjusts the air speed. Air speed valve closest to aircylinder is the UP Speed adjustment and the other is the DOWN Speed adjustment. These
should be adjusted so that a smooth UP and DOWN motion is achieved. Turning air speed
valve screw, located at the end of air speed valve, Clockwise Decreases speed and
Counterclockwise Increases speed. Pressing (3)FRAME BIAS key and adjusting air speed
valves at the same time, setup will be obtained. (NOTE: This may take several attempts.)
15) Z-Height is adjusted by using item 4 (See Page-9). Pressing (2)FRAME BIAS key, adjust
Z-Height by turning item-4 Clockwise to Lower and Counterclockwise to Raise Punch. Move
leadframe over Punch Bushing Die (See Page-13), item-8 (See Page-9) to check for proper
lifting height. Proper setting is when Punch Bushing Die lifts leadframe approximately .005-.
010 mils.
16) Next is to adjust Shock Absorber item-5 (See Page-9). With the Punch in the UP position,
turn the Shock Absorber until it just makes contact with bottom of side of upper plate item-6,
turning Counterclockwise to Raise and Clockwise to Lower. Once this is complete, tighten
Shock Absorber Nut item-7. The Punch Z-Height is now completed.
(NOTE: THIS ADJUSTMENT MAY TAKE SEVERAL ATTEMPTS.)
17) Adjust Bias Solenoid Assembly by loosening item-1 & item-2, on Bias Solenoid. "DO NOT
LOOSEN ITEM 3". With leadframe still in punching area, push (2)FRAME BIAS, solenoid
should now activate moving Pin inward against the leadframe. If Pin does not move, loosen
item 1 and adjust so NO BINDING occurs. Do not allow PIN to slide OVER or UNDER
leadframe. Once adjusted, tighten item-1. " WARNING DO NOT OVER TIGHTEN OR
BRACKET MAY MOVE AND CAUSE BINDING, BENDING OR BOWING OF PIN! ".
(NOTE: This may take several attempts.) At this time, the Pin item-6, should make
contact with the leadframe and hold it against the Rear-Rail. Leadframe should not BOW or
BEND leadframe, if either or both occur, turn Solenoid item-4, Counterclockwise to Backout
PIN and Clockwise to move PIN In. Once completed tighten nut item-2. " WARNING DO
NOT OVER TIGHTEN OR BRACKET MAY MOVE AND CAUSE BINDING, BENDING OR
BOWING OF PIN! ". (NOTE: This may take several attempts)
Last is to adjust the Pin Stop Bracket item-5. With the Pin item-6 inward against the
Leadframe, adjust Pin Stop Bracket item-5 by loosening set-screw item-7 and adjusting
bracket so approximately .125 mils is between End Pin item-10 and Pin Stop Bracket item-5.
Tighten setscrew. (See Page-7)
PAGE 4 - REV. L
18) Next, with the Punch in the UP position, pressing (2)FRAME BIAS, move leadframe away
from Punch Bushing Die area. Pressing (3)PUNCH/BRUSH key will manually RAISE and
LOWER THE PUNCH SLEEVE ASSEMBLY. Adjust speed by using item-3 (See Page-9), so
that a smooth Up/Down motion is achieved. Once adjustment is done return Leadframe
over Punch Bushing Die.
19) Have the Punch in the UP position, by pressing (2)-FRAME BIAS. The Rectangle type
Punch Sleeve Pin is 90 degrees to the Punch (See Page-9). If punching a Horizontal lead,
the Sleeve Pin should be Vertical and if a Vertical lead, Sleeve Pin is Horizontal. Use the
Punch Sleeve Pin as a reference. To adjust turn Punch Sleeve Nut in increments of 1/2
turns for Rectangle Punches and 1/4 turns for Rounds Punches. Next position a lead from
the leadframe over the Punch Bushing Die area; it may be necessary to have the Punch in
the down position. Once setup, press (3)PUNCH/BRUSH, at this time the lead should be
punched, if it is not turn Punch Sleeve Nut Clockwise to Lower and Counterclockwise to
Raise (See Page-9). (NOTE: Punch Assembly is pre-set at the factory, so it is possible
that no adjustment may be needed). Execute this step until a lead has been punched and
the lead is approximately 0.050-0.060 mils set into the Punch Bushing Die. When
completed, turn OFF machine, then wait about 30 seconds, and then connect item-13 (See
Page-9). This completes all mechanical adjustments.

Next is to set the Punch Parameters for the leadframe that is being punched. Instructions are
as follows for LFI3010/20/60 Reject Identifier Instructions. If the punch is activated in Mode 910
shows then the punch will need to be programmed. Press “PARAMETER SELECT” key and
press the “ENTER” key until the display is shown below for the Punch Option. NOTE: For
more accuracy, use a drawing of the leadframes.
DID Status
Indicators
L/Punch
*OFF
This example assumes that the default setting was for a PUNCH and the existing program
contained NO punch information and the leadframe is not interdigitated. This would result in
NOT punching the rejected devices although the machine itself has punches on it. This allows
some leadframes to use the punch option and others not to. If the punch is new on the machine
then the display shows "OFF" as above.
Next is to turn on the punch and this is done by pressing the “CLEAR” key, then pressing the
“NEXT” key to change from “OFF” to “REJECT. To change back to “OFF” press the “LAST”
key. Press the “ENTER” key to activate and the display will be shown below.
L/Pn Ya
*200
Xid
R1.
delta
OFF
The "Ya" parameter is the distance from the rear edge of the leadframe, forward to the desired
punch position. When programming the "Ya" value in interdigitated mode, the first device
position must be used. The machine will calculate the other position from the programmed
value. NOTE: By default there may be some numbers shown on the display, just disregard
them. Press the “CLEAR” key to remove any values shown.
To program the punch “Xid” position, first clear the existing value if any. Next, push the
“NEXT” key to indicate the “Right Side” of device center or the “LAST” key to indicate the “Left
Side” of device center. Next, enter the distance from the device center to the lead that is going
to be punched. For example, if the value is “1” then the punch with punch a lead 1 mil to the
right side of the lead/leg.
PAGE 10 - REV. L
Once the “Xid” position has been entered the display will be as shown below:
L/Pn Ya
*200
Xid
R1.
delta
OFF
The "delta" value will usually be “0” (displayed as "OFF"), as shown in the sample display
above, which results in a single punching operation. There are two uses for the "delta"
variable.
The first use is to allow for a longer punchout length than the punch itself. This function can
only be used to extend the punchout length in the “X” direction (left to right). It has historically
only been used on PDIP type leadframes because the Punch is .125 mils long, so if leads/legs
are longer than longer punch length will be needed. Programming the “delta” variable to
increase the length between the desired punch-out and the actual punch length uses this
feature. For example, if the leg length is 140 mils and the punch itself is 125 mils then the
"delta" variable would be programmed for 15 mils. After the first punching operation then the
leadframe would be moved 15 mils and a second punching operation would be performed.
The second, and currently becoming most common, use of the "delta" variable is to allow
multiple legs to be punched out, “2-9 leads/legs”. This can be done in either the X direction (left
to right) or the Y direction (front to back). The desired direction is indicated with an "x" or "y"
preceding the "delta" value. To select the direction push the “NEXT” key for "x" or the “LAST”
key for "y" after clearing the current "delta" value and before starting to enter the new value.
To disable the "delta" (second punch) operation instead of pushing the “NEXT” or “LAST”
keys push the “ENTER” key.

x50
#
2
Once a value, other than “0” it will displayed as "NONE", if any other number is programmed
into the "delta" variable the display will show a "#" and a "2" as shown in the display above.
This variable is the number of punch operations to perform. The original punch operation is the
first and by programming a delta value that indicates at least two punch operations are to be
performed. This value can be programmed from “2 to 9” punched leads/legs.
Usually “2” are used to punch multiple leads/legs out of the defective device. Finally, there is a
way to punch multiple legs that happen to be around the center of the device in the X (left to
right) direction. When punching multiple legs in the X direction, the punch after the initial one
was punched it will move toward the outer edge of the device. Thus, if the first punch location
was programmed for "L200", then the first punch position would be centered 200 mils left of the
center of the device in the X direction. This default system means that it was not possible to
program the machine to make multiple punches, which crossed, over the center of the device.
In other words, all punches would have to be on either the left or the right side of center.
However, some applications required that some of the punch operations be on one side of
PAGE 11 - REV. L
center and some on the other. To allow for this requirement an additional indicator was added
to "#" value field. Anytime the cursor is at the "#" value, pushing the “MD” key will toggle ON or
OFF a "c" indicator after the "#" value, see display below:
L/Pn Ya
*200
Xid
R1.
delta
x50
#
2c
Notice the "c" indicator after the "2" value in the "#" field. This means that all punch operation
after the first is towards the center of the device from the first punch. This allows the first punch
to be left of center with the next punch operations moving towards the center and possibly even
over into the right of center, depending on the programming values. This direction indicator is
toggled on and off by using the "MD” key when the cursor is at the "#" field location. (See
Pages 13 & 14)

TOWARD THE CENTER
PRE-CISOR Programming
If the Punch is programmed to be active then after the Elevator parameters are programmed the
display will ask for the Pre-Cisor value. The display will be as shown below:
Shuttle Pre-Cisor Location
*NONE
The Pre-Cisor function is only available to be used if the machine has a Punch installed and the
program has selected the Punch to be active. The Pre-Cisor is used for increased repeatability
of the punched position in the X, left/right, and axis. The Pre-Cisor is able to compensate for
aging of the frame sensor; leadframe slip in finger and errors caused by semi-circular leadframe
edges. The Pre-Cisor works by using the frame sensor to precisely locate the center of a hole
along the leadframes length. Once this programmed hole-center is located then the machine
will correct for it's actual position and then move to the corrected punch location. The
programmed hole must have a minimum diameter of 50 mils (1.25 mm), it's center must be 55
mils +/- 1 0 mils (1.4 mm +/- .25 mm) from the edge of the leadframe and the programmed hole
must repeat at least once per "INDEX" position. The vast majority of leadframes, other than
power, which usually have no need to use the Pre-Cisor, have holes, which will be within these
specifications. Those leadframes, which DO NOT have such a HOLE, cannot use the Pre-Cisor
function. The number programmed must be the distance from the leading edge of the
leadframe to the center of the selected hole. Although any of the repeating holes can be used
up to the maximum allowable number usually the first such hole center is used (See Pages 1314).
50 MILS
55 MILS +/-10MILS
To disable the Pre-Cisor function simply program the value to be "O”, which will be displayed as
"NONE".
PAGE 15 - REV. L
21) The last step is to “CALIBRATE” the Punch by using “Mode 998”.
NOTE:
Models L or B1500/50/60 and L or B3000 do NOT have this function, also some newer
models may NOT have this function either. Only certain machines with the proper software
revision levels will apply. At this time, a magazine with dummy leadframes will be needed.
Once the Leadframe and Punch parameters are set for the leadframe (See Page 10-14). If
the Pre-Cisor feature is used, make sure it has the proper parameter setting (See Section-1,
Page-20) this will insure proper Punch calibration procedure. Press “MODE SELECT” key
and clear existing mode and enter “998”, at this time there will be a “WARNING” message
on the display, to continue press the “ENTER” key, to exit press “MODE SELECT” key. To
continue, enter the slot number for leadframe that will be used for the calibration, which will
typically be slot “1” then press the “ENTER” key. The leadframe will be pulled out of the
Conveyor and the Punch assembly will move forward to the lead that will be punched.
Identify which lead/leg is to be punched and center it with the Punch Bushing Die hole (See
Page-13), in the "X" and "Y" directions, this is accomplished by using the “Numeric” keypad
to move the punch electrically. The “8” key moves Punch backwards, “2” key moves
punch forward, “4” key moves punch to the left, “6” key moves the right, “REJECT” key
lifts the punch and “5” key does a sample punch. The “NEXT” key moves leadframe to the
next device and the “LAST” key moves leadframe to the previous device. The objective is
to calibrate the Punch to the value that was entered in the machine, Xid and Ya Parameters.
Once completed, press the “ENTER” key to store the Calibration value. “NOTE: THIS MAY
TAKE SEVERAL ATTEMPTS”
22) Install covers and Scope mount if applicable.
Allteq recommends running some sample leadframes to punch on the machine before being
released into production.
Once completed Punch will be in optimum working condition.
