Hi Poh! The visual appearance of a solder joint is not necessarily an indicator of a solder joint's reliability. The old "bright and shiny" criteria should have become extinct but some old habits apparently have a life of their own. IPC-STD-001B, paragraph 9.2.4 "Solder Connection" is one reference you can use to demonstrate to your customer that "bright and shiny" is not a requirement. Good Luck.

Hi Technetters, Is there anyone able to help me on having a smooth shining solder joint on gold-plated PCB. As I understand that the board with gold-plated gives a relatively dull joint. However, I have issue convincing my customer that this symptom is normal.
