Good advises thanks. I'll go thru all nozzles and vacuum check today and tell the programer about PD's and nozzle vs shutter. Should I check at the same time all the vacuum filter ? For the placement test, we use the same feeder at the same position.

Checked the condition of your nozzles? Vacuum ok? Dummy part picked from the same feeder position? Dummy part picked from the very same feeder? How often does this problem occur? How many dummys did you pick for comparison? Sometimes a feeder calibr

I don't know how in Panasonic - in Yamaha and similar pressure / vacuum is calibrated for each head and nozzle - maybe you need to calibrate?

Good day everybody, I am looking for a number of portable vac-operated pick-up tools; to be used by operators, so they can pick QFP's/BGA's etc. out of matrix trays and also to put components back in the trays. It should be slim, ESD-safe and powere

We have two GSM machines (4-spindle, single beam) and had a camera fail on one machine. We decided to clean and calibrate the cameras on both machines. One machine we had no problems and all is working properly. The other machine will not pick up the

Hi Mefunak, I'd say that the vacuum holding circuit is at fault. If the component is picked OK from the feeder ('vacuum check after pickup' is switched on) then the component is being dropped from the head as the gantry moves to the placement positi

Hi Steve, Have you took the star completely off the Gantry. There are the 12 hoses to the star if Segment 1 connection hose is messed up everything will be off because everything gets measure off of Seg.1. Also, you could start eleiminating the probl

1.- Check your vacuum a.- Check filters b.- Check air flow (the vacuum is generated by a Ventury using air flow, not air pressure) c.- Vaccum vias (Possible linth inside the vacuum lines) 2.- Check the nozzle condition (Probably broken o

Based on the pickup surface area: 1. Use the biggest nozzle possible, 2.Keep in mind that some nozzles have bigger inside diameter hole(more vacuum) 3. Keep in mind that some pickup surfaces are rigid(not really flat surface) - use rubber tip nozzles

With Essemtec software you can specify to turn on vacuum once the nozzle is down at the part. The default method is to turn on the vacuum while the nozzle is up, but starting to move down. For light/tiny parts this can have the effect of making them
