I think its kinda Ag, but on mine it seems not really lasting.
Because the holes not soldered yet look more and more copperish.
Anyway,
they are a Dream to work with !

Hi,
....the parcel has arrived. Professionally packaged, obviously.

Greez & Thanks to all involved in this affair.

SigFire

The PCB alone looks impressive. A real work of art.
Have considered to pin it gainst the wall instead of a "Baselitz".

Better using some silver and copper content leaded solder then. Like Cardas quad.

No station.
Ersa Multitip 230/25W
Perfect joint in <1 second !
But you have to use a tip for leadfree.

ERSA has good handhelds. They heat up to 450C to battle tip mass slow heat recovery though, so its best to solder each point fast but wait just a bit between points. Also to wet the tip with solder always when idle because the high standby temp oxidizes handhelds faster than stations.

No lead-free for me (Iím an environmental mad soldering criminal ) to many issues, like cracking, creeping and more (with the lead-free stuff ). A healthy silver content is strongly advices.

To S. Damn right

To Frans,
heard about those issues.
Using leadfree for at least six years none of them appeared,
so far...

What they removed in lead, worse toxicity they added in aggressive flux for the operator. What are the impressions with your new DS2072?
