I am trying to start in the interesting work of bga soldering before my sight prevents me from fine work, some chips are bonded with a resin which is under them preventing hot air to flow underneath.
I have contacted Electrolube who say that a cleaner OP9003 will remove resins, they sell it in 5Ltr lots either in one large tin or x5 1Ltr tins for about £60-70.
I am looking for a person willing to sell me a 1Ltr tin at a cheaper price, can anyone help me please??
Many Thanks from Deltatango
