We have used small hi temp labes, that are placed on our panels, boards before reflow. Each operator has a roll of labels with an assigned number. 4 operators, label 1, 2, 3 and 4. It worked well for us.

I am looking for a bar code scaning system to help our feeder setup. Can anyone provide me with some information regarding this? Thanks a lot.

I was looking to see how others are handling conformal coating PCBs containing BGAs. We have looked at underfills, but none meet the reworkability we need.

We agree that coating BGA solder balls with conformal coat is a bad idea due to differences between the z-dimension thermal expansion between the conformal coat and solder.

Whether or not conformal coating creates a reliability problem if it bridges the gap between the board and bottom of the part depends on the properties of the coating. A low modulus coating is fine, but one thats modulus increases at colder temperat

Thanks for the replies. I use a foam fluxor, so the pallet is well fluxed. This is my first expierence with this thick of a pallet. Maybe Russ has a handle on it when he says that the wave height is just too high.

I have seen the solder shoot out at least 4"-6" from both the leading and trailing edge when this happens. If the open pockets are real deep you may want to use a turbulent/chip wave for soldering, sometimes this leaves bridges however.

We have a CRT RTI-6500. I have heard that a company in Ca. now supports the CRT line. Does anyone have info about this? Any help would be great. Thanks in advance.

I wanna make a MSExcel spreadsheet that will automatically convert Percent Area of a BGA void to Percent Diameter. What is the formula? Thanks and regards,
