To pick or not to pick, that is the tweezer.

How do you handle wafer pieces to submerge them in HF acid and other cleaning baths?

You use tweezers, but HF will eat away any metal ones, and I would not trust much else other than HDPE plastic that can withstand it. However, I did not find accesible (cheap) ones, so I decided to make them, it’s funnier and cheaper. Too thick stock coupled to a short endmill marred the edges a bit, but it proves the point, once I get thinner HDPE sheet, I’ll make some more.

It picks the wafer square by the edges, allowing it to rest in the ledge, making for a very secure hold, no need for double sided tape or other feeble methods.

See ya!
