Im using kingbo aswell in a syringe, it's been my go to flux for a while now as its easier to work withI'm using a grossly oversized tip honestly because I haven't felt like replacing it, but I can 2nd the importance of low-temp solders for things like this.
Good thing solder has flux in it. What on earth type of flux were you using that smells like food? Personally, I use Kingbo RMA-218 BGA flux. Use the syringes, not the jars.
