Play around and setup the coplanarity in Fuji Flexa and see if this can help you at all. Other than that I wouldn't have a clue as to what it might be.

Have you checked the component height in the package data to ensure that it is the same? how about the PCB itself, could there be some warp or twist thay may cause the component to be dropped onto the board? any support problems? this is all I can

In production,we are seeing high defect for Hair Line Solder Shorts for PTH connector and the Hair Line is too tiny that X-Ray and ICT could not detect.Any suggestion on how we can resolve or at least detect this upfront.

All possible causes aside, how can a dead short pass your ICT unless the connector is not probed.

They can be expensive and if your using water soluble chemistry you will have to immerse the pre-form into flux. Asking the vendor to provide flux with the pre-form I believe it would dry out prior to use.

boards greater than this spec. can cause latent failure, Do not confuse no-clean assembly materials (nocleaning required) vs. clean chemistries that must be cleaned. You do not want ionic contaminants on your products.

Hi, Sometimes we have the following error: " TABLE BASE NOT GOOD ". In the manual, it says that we have to check the cylinder and other parts around the table. This is not very specific. Can anyone helps us with some hints? Thank you

As Steve said do not re-refrigerate. You can also take the paste out early. We remove enough paste from the refrigerator for a full days work around noon the day before we use it. Jerry

Moisture will condensed on your paste if the temperature different. Solder bead will happen. You can see the jar or cartridge wet when you removed your paste from refrigerator.
