It describes the standard configuration of inspection head (component inspection)-installed NPM-W2 system

■Type 1

Place a reload conveyor in front of the machine equipped with the inspection head (component inspection), or

place an ejection conveyor just behind the machine equipped with the inspection head (component

inspection).

●Reload conveyor: Reloads reworked PCBs.

●Ejection conveyor: Performs tasks, such as locating a defect/reworking a PCB/registering the PCB for

reloading, in the case a component is rejected at inspection.

Name Explanation

1 DGS (Data Generation System) Newly creates or edits production data.

2 LNB (Line Network Box)

Saves production information obtained from NPM-W2.

(e.g., inspection result information)

3 LWS (Line Work Station) Edits and adjusts (tunes) inspection data during production.

4 Option display

*1)

Displays defective areas for ease of rework.

5 Barcode scanner

*2)

Reads a barcode on a defective PCB when the PCB is

reloaded via the reload conveyor after rework.

6 Reload/Ejection conveyor

*1)

Reloads reworked PCBs/removes defective PCBs.

*1) Devices to be prepared by you

*2) NPM-W2 standard optional devices (only wired type can be used)

For reloading a reworked PCB, devices 4, 5, and 6 above are required. (→P.4-5)

■Type 2

Mainly for the purpose of making the length of production line shorter, any ejection conveyor that performs

reload operation or reworks PCBs will not be placed in the line.

●In the case where the machine equipped with an inspection head for solder inspection use is placed first in

the production line (→P.5-1-2)

■Type 3

The machine equipped with the inspection head (component inspection) will be placed last but one in the

production line (the second machine from the last one).

●Components that need to be checked for foreign bodies shall be placed as follows, provided that the

components include both reel and tray types.

However, you cannot conduct post-placement component inspection or reload operation in downstream

processes after a component is placed.

●In the case where the machine equipped with an inspection head for solder inspection use is placed first in

the production line (→P.5-1-2)

(Removal/rework of PCB)

●To rework or remove a PCB using the ejection conveyor, it is necessary to set up the position of the

ejection conveyor placed in the line with LNB. Please use “LNB configuration information” of LNB for setting

“Ejection conveyor” to the position of the ejection conveyor in the line.

For information on how to set up, (→ Chapter 4 in [LNB] operating instruction)
