NPM-W2 EJM7DE-MB-04O-00

By installing the 2D inspection head to NPM-W2, various inspections on a production PCB can be performed.

●Component and solder inspections (→P.5.1.2) can be performed based on the production data.

4-1-1-1

●Checking for the presence/absence, displacement, flip-over, or polarity of components (chips, etc.) placed

in the processes upstream from NPM-W2 equipped with the inspection head prevents a defective PCB

from flowing into the downstream process.

●It is possible for inspection head-equipped NPM-W2 to check components (including shield cases and

BGA) for foreign bodies (→P.4-5-1) before placement so that a defective PCB cannot be flowed into a

subsequent process.

●When, for example, a defect is detected in the test for the presence of components, you can visually

locate the defect on the over judgment input screen, which allows you to make a change in the test result

or check the location of a defective component.

This saves components since no more components will have to be placed in downstream processes once

a defect is found.

●A defective PCB, removed from the inspection conveyor, will be reloaded via the reload conveyor after

rework, and be inspected/placed so that the quality of PCBs can be ensured on production line.

(Please prepare reload/ejection conveyers on your own).

●Since inspection results can be summarized by the nozzle or feeder, you can easily identify/deal with

error causes.

Constraints

●The inspection head designed for component inspection use shall be installed only to the front side of

NPM-W2.

●As for NPM-W2 that carries out inspection and placement operations, under the optimization of DGS, only

[Alternative placement] can be used for [Placement mode] but [Independent (for the front lane)] or

[Alternative (for the rear lane)] are not available for use.

1)Defective PCB: A PCB that the inspection head or an operator judges as defect.

2)Defective component: A component or its placement status that the inspection head or an operator judges

as defect.
