Just what is delaminationg during testing? Water washing should be sufficient to clean WS609. On the other hand, it's possible you're conveyor speed is too high to do a good job cleaning the high density areas. What kind of testing have you done to

I have seen a similar problem once about 15 yrs ago. Someone decided to try a water wash flux for tinning wires. Bad idea! The wires were dipped in the flux, then in a solder pot. As the lead tin's it forces the flux in the strands to move up the wir
