Measured surface
material
Copper foil + resist face, There should be area of at least 1.5
1.5mm on the copper foil and silk face.
The transparent and semi-transparent area are not target. (Glass
epoxy material face)
PCB warpage
amount
Upper warp: 2 mm or less, lower warp: 2 mm or less, and warp
gradient:0.5 % or less, The difference in height of an edge line
(transfer direction): 1 mm or less.
Function
Warpage toralrance
detection
If the measurement result exceeds tolerance, give a warning before
placement start. Also confirm the tolerance warp gradient (%).
Height control
Measures the PCB whole height (warpage) and control the
placement height.
Measured data
transfer
The data measured in the head machine in NPM-W is transferred
to the downstream machine.
The machine in downstream must be NPM-TT2. The data cannot
be sent to the machine other than NPM-TT2.
Regarding a PCB that the warpage shape varies each time it is
clamped, please consult us.
It controls the nozzle height when mounted by measuring the height (warpage) of the entire PCB.
If the measured result exceeds tolerance, give a warning before mount start to prevent the occurrence of PCB
quality defect.

At
a glance
*1) Correctable warpage by PCB warpage correction using the height sensor, the cross-section is a single U
type curve.
For complex warpage, using pattern warpage correction allows correcting a PCB as simple curve
combinations.
As for a PCB with slip (cutout) or thin PCB, warpage shape may be complex, so that we recommend to use
pattern warpage correction. (→■Pattern warpage correction)
*2) Choose the height sensor for the first NPM-TT2.
In single lane mode production, choose the sensor only for the front side, and in dual lane mode production,
choose the ones for both front and rear sides.
*3) For the maximum set number (total) of measuring points, see [6-1-1 Program data of machine specifications].
Measurement
condition
Height
PCB top surface ±4 mm (Area to be measured. It is not PCB warpage
tolerance)
Area Area of 5mm from PCB edge and cutout.
Points
*3)
Overall warpage correction : 9 points or more (up to 25 points/PCB)
Pattern warpage correction : 9 points/pattern or more (up to 25
points/pattern)
Measurement time
3.0 s (The value is under optimum condition when nine points on PCB
of 510 590 mm are measured)
■Pattern warpage correction
Warpage correction at measuring point per pattern is called pattern warpage correction (see below).
As for a PCB with slip (cutout), warpage shape may be complex and not be smooth (uniformed) curve.
In such a PCB, we recommend to use pattern warpage correction.

Function
Data creation
function of the
support pin
arrangement
Checking the reverse side image downloaded to the DGS
window with the placement coordinates of the front side, the
machine visually decides the arrangement of support pins
and creates the production data.
●The data is created on DGS.
