Послали куда подальше. Рекомендуют мыть просто водой.
Может быть стандарты IPC что-то пишут о том чем можно мыть? Никто не в курсе?
Hello sir,
Thank you for your further reply, sorry for the inconvenience.
There is no the same complaint in the same batch orders, according to your picture, the solder mask ink seems was attacked by the organic solvents, our engineer also doesn't suggest washing the board with organic solvents, since it will attack the ink. so please kindly have a try to wash the board with clean water, is it ok??
In one word, there will be many factors that caused this issue as below:
1) our board can not bear the withstand interference of ultrasonic vibration, please kindly have a try to avoid it, is it ok??
2) and since the main component of the ink is organic, and the solvent will attack it, so please kindly use the clean water, have a try, is it ok??
Please kindly have a try to test and avoid the 2 factors as above, any updates, please feel free to contact us.
Looking forward to your update,
Best regards,
Jojo
