davef, thanks for feedback. I talked with a plater who said they put copper before silver when plating brass. Would a complete stack of: Brass part, then 0.0001-0.0002" of copper, then 0.0005" of silver, then Tarniban anti oxidation. Sound reasonabl

IPC-A-610E-2010, Acceptability of Electronic Assemblies, 8.3.4 Castellated Terminations talks to the acceptability of solder connections on components like yours. It’s tough to say from the pictures, but I’d say your issues are: Missing solder: Plat

Certain board designs require the unavoidable use of non-plated holes and slots. Presently, this requires a trip back to the drill house to open up the aforementioned holes, to remove the unwanted plating. In situations requiring non-plated holes and

What is the disadvantage of palladium plating instead of gold plating? I saw many advantage of palladium plating in term of hardness, wear resistance, and price but why most of the PCB Industries still use gold in PCB pad? Thank you

Hi Mark, Couterbore is possible in two way's during PCB Manufacturing. Couterbore plated and non-plated. Meaning that the entire hole will either have to be Plated or Non-Plated. Prefered Methode is Plated, to accomplish this your PCB house would
