■ Standard line configuration
■ Other line configurations
Position of inspection head or conveyor can be allocated flexibly depending on purpose.
1) To shorten length of line
Allow all NG PCBs from Solder Inspection (SPI) and Component Inspection (AOI) to stop altogether at Ejection conveyor which is located at the end of a line. Placement points or patterns judged as NG at Solder Inspection shall be automatically skipped through placement and Component Inspection.
2) To execute foreign object inspection for two types of components in Reel and on Tray.
Foreign object inspection is carried out to inspect presence of such object under specified components.
When an object is found, the specified components are not mounted. Therefore, the components need to be placed on the table opposite from inspection head or in a downstream process. When Reel and Tray types are mixed, please arrange as follows. However, please note that it is not possible to execute component inspection after placement of components in a downstream process.
* The above line configuration is a sample.
It may differ depending on your system configuration and the like. For details, please contact us.

■ List of optional functions and required peripheral equipment
When using the following options, it is required to prepare peripheral equipment according to each function.
Optional function Description Peripheral equipment
Solder inspection NG ejection function
Based on inspection results of PCBs that are ejected from NPM-W, OK/NG signals are output so that NG PCBs are stopped on the ejection conveyor and OK PCBs are passed through.
Also once a PCB is removed from conveyor to repair or to re-check, a function is needed to output a request signal to eject the next PCB to NPM-W.
Component inspection NG ejection function
Re-putting function It operates together with “Component inspection NG ejection function” as a set. This function allows you to put a repaired NG PCB, inspect, and mount again which failed to mount with the opposed head.
In addition, the PCB removed with NG is managed by the barcode. Reading the barcode during the re-putting enables tracking management.
NG map display function Although NG position can be confirmed on equipment screen, this function enables to display it on a PC screen also for component inspection.
Pattern information communication function
When a defect is found during solder inspection, skip placement to the defective pattern to minimize cost of component loss.
Also, when a defect is found during land inspection, skip the defective patterns can minimize cost of component loss similarly.

With OK signal control of inspection result from pre-process NPM-W, only one PCB shall be stocked.
Also, the following transfer operation specifications must be satisfied.
(1) PCB loading wait operation
During stand-by status without NG PCB in stock, transmit Board Available (BA) status signal from pre-process to post-process, and Ready status signal from post-process to pre-process.
(2) NG PCB stock operation
1) When OK signal is ON at the loading of PCB
At the start of PCB loading, turn OFF Ready signal to pre-process and unload the PCB as it is without stopping.
2) When OK signal is OFF at the loading of PCB
At the start of PCB loading, turn OFF Ready signal to pre-process, and after placing PCB on conveyor as a stock, turn OFF BA signal.
(3) Transfer restart operation after stocking NG PCB
Execute the following operations by inputting foot switch etc.
1) When NG PCB is present
As it becomes unloading stand-by status, turn ON BA signal to post-process.
After confirming the Ready signal is ON, unload the PCB to post-process.
After completing the unloading (confirm Ready signal of post-process to turn from ON to OFF), return to operation # (1).
2) Where there is no NG PCB (removed).
Return to operation # (1).

Re-putting function ・When the re-putting switch is pressed, PCB transfer is stopped by receiving an order from NPM-W. The PCB ejection stop signal is transmitted to the NPM-W in the upstream via FA PC (LNB).
・Required information of PCBs is scanned by the barcode reader ,and then the PCBs are placed on the conveyor prompting them to be sensed to implement their loading to NPM-W.
・The following transfer operating specifications must be satisfied.
(1) PCB loading wait operation
During stand-by status without NG PCB in stock, transmit Board Available (BA) status signal from pre-process to post-process and Ready status signal from post-process to pre-process.
(2) PCB stock operation
Placing PCB at stand-by position brings the machine to PCB stock status, turning OFF Ready signal to pre-process and BA signal to post-process.
Other than the above, at the start of PCB loading, turn OFF Ready signal to pre-process and unload the PCB as it is without stopping.
(3) Transfer restart operation after stocking PCB
As it became unloading stand-by status by input of foot switch etc., turn ON BA signal to post-process.
After confirming Ready signal of post-process is ON, unload PCB to post-process.
After completing the unloading (confirm Ready signal of post-process is turned from ON to OFF), return to operation # (1).

・Please purchase the optional wired scanner.
・Please prepare the barcode for re-putting by yourself.
Any numbers are available if they are corresponding codes with our wired scanner.
It is recommended that you attach the barcode to the box or rack, in which PCBs are stored, not directly to PCBs, and scan the barcode on the box or rack.
As for the PCBs that have the barcode, which corresponds with our wired scanner, already being attached, it is possible to scan the attached barcode.
