We have an assembly that requires a number of high density connectors to be placed after SMD. The process will not allow a normal wave solder setup due to the population of SMD comps. We cannot use a selective solder pallet due to profiles. We are looking to us an Air Vac mini wave to selective solder these connectors. We are concerned that we get good solder joints for the connectors. We are thinking of using our standard OA flux but concerned we may not have preheat to activate the flux. I am interest in hearing from people that have done a similar process and how they setup and what chemistry they used. The boards can be cleaned with a Aqueous batch cleaner after this process.
Looking for some good recommendations....
Thanks,
Kevin
