Accuracy verification
■MCDATA type
MCDATA (production program) is exclusively used for accuracy verifications.
There are the following two types of MCDATA used for placement accuracy verifications.
Offset Refection MCDATA
*The one with “Ost” included in its
data name
The front and rear heads execute placement independently from each
other, and the placement locations are measured. This is used to
reflect the each-position-angle offsets, obtained from measurement
results, separately as the front or rear head use.
Accuracy Verification MCDATA
*The one with “Ins” included in its
data name
The front and rear heads execute alternate placement that is an
operation close to normal placement, and this is used in measuring the
placement locations.
MCDATA filename
W2 - L16 -L16 - F – F _ 05JIG - Ost ＊＊＊
■Reflection of verification data
Make sure not to reflect the each-position-angle offsets, obtained after measurement, in “Accuracy verification
MCDATA” because the MCDATA is used for verification purpose.
When using MCDATA for component placement, the following message appears before the start of production.
Select [Yes] / [No] according to the type of the data you use.
●When accuracy is verified using ‘Offset Refection
MCDATA’ (-Ost)
●When accuracy is verified using ‘Accuracy Verification
MCDATA’ (-Ins)

1) If ±0.025 mm support is optionally selected, only chip accuracy verification (± 0.025 mm support) is
performed and chip accuracy verification is not performed.
2) Perform it when using a 3-nozzle head to mount a component with □12 mm or less.
■Target value for accuracy verification
NPM-W2 is capable of providing support for high production mode (placement accuracy 40 μm) and high
accuracy mode (30 μm). Use high accuracy mode in accuracy verifications.

tion
(→[Operating Procedure] P.2-3-4)
The dedicated MCDATA (production
program) is used for accuracy verification
and registering the each-angle offset.
When the each-angle offset is reflected,
machine parameters in the machine will be
rewritten.
●You are recommended to save the current
data beforehand just in case.
1) (→ P.13-21-1
-2 ‘■Order of verification’)
2) Check both lanes 1 and 2.
This section describes the procedures for measuring the machine’s placement accuracy and registering
each-angle offset by using that measured result.
