There are problems when using paste in mass production

  • I bought the AuSn paste and tried to use it, but it does not melt properly. I would like to discuss how to improve it.
  • I purchased the AuSn paste, but does not melt even under the recommended reflow conditions, probably due to the circuit board being made of a special material.
  • I want to try using the AuSn paste, but I do not own the proper equipment's yet, since it requires a large initial investment to try.
