The Tant size is 3528-21. I use type 72 nozzle > for it. check your vacuum valve, manually turn it on and off,i have the same problem like that b-4, after replacing the vacuum valve, the problem went away.

Here are a couple of things to look at. 1. Watch the machine run....and if it misses a part....make sure it doesnt blow out the next part being presented. Sometimes the air pressure is too high and the vacuum verify will blow the part out of the poc

First, plug all holes with nozzles or plugs. Then use I/O diagnostics to fire changer up and activate vacuum. Then try to remove each of the nozzles and see if the vacuumm holds. If it does, check vacuum detector switch (mounted on changer side). The

I'd start by checking and reteaching the nozzles (this is automatic, it'll measure the nozzle length and vacuum values for each nozzle). After that double check the value you have entered for the PCB thickness as this will impact where the machine t

Maybe also check the air pressure, the lack of air pressure could also sometimes make the head lose grip on the nozzles

Jacky, we have had a similar problem. We needed to go to a smaller nozzle and also check your vacuume system and air kiss.Could be after placement when the machine blows air to insure the part is off the nozzle that it is effecting the solder brick.

Doug, Depending on the machines in question, the release characteristics change. Most of the mechanically driven machines simply stop the vacuum by lowering the nozzle and release the stored vaccum at impact when the nozzle starts to compact back int

You have given little detail for anyone to help. What types of components are laying in the machine? Are these components missing from the PCB? But you can check these things. 1. Check vacuum at nozzles 2. Check for obstructions in the path of the

Thanks Steve. I do know that my vacuum and height/pressure are as they should be. You make a good point about the saturation of the paper. I will certainly check that.

I would like to hear from all Philips Sapphire users about your successes and failures when placing 0402 parts. 1. Are you using type 51 / 57 nozzles? 2. Special vacuum check? 3. How are you calibrating your vacuum sensors? 4. Have you expe
