Our supplier is recommending against plugging via holes the immersion silver boards and here is their explanation. Need some input into how you guys are managing.

"We can not plug before silver because chemicals used during the silver process may become trapped. Over time these chemicals can eat away at the hole wall copper creating voids.
2. Because the boards have passed through rout and are in piece form when silver is applied the board can not be plugged in panel form as are the gold boards.
3. Immersion silver is soft and easily damaged. It is our last manufacturing process and we avoid handling it as much as possible after being coated, this particularly applies for the plug process."

Appreciate your feedback.
