How thick is this pallet? 6mm, 8mm, 10mm? I would look at: Make sure you're pot height is correct (lead clearance). If you are burrying the pallet in the fountain, your going to "push" a large volume away. The solder "push" should not plow over t

Higher Tg values are only one thing to look out for. Two other things that are very important to watch are the Td or Decomposition Temperature (the temperature that the epoxy actualy starts to break down), and the CTE for the material. Some Tg 14

Yeah, adopting is the right word. In this new lead-free era spec.'s are made to stay within the scoop of the RoHS directive. The driving force for spec.'s should be reliability. Did you see any impurity level spec.'s yet in wave soldering for Cu, Au,
