Armin, I can supply you but wont. Why not? Because these materials have a short shelf life when packed into syringes. Your local supplier should be able to provide them but he will be obliged to make up a batch of 2 - 300 to be economical - but they

Hi Mark: Running a wire under a BGA is possible, however if you plan to mount the BGA over the wire you would want to make sure that the wire insulation will withstand the heat of the reflow temperature. A more reliable way would be to lay a trace
