I have a lot of breadboards I've acquired over the last 30 years or so. There are quite a few I would describe as cheap junk, but only one is magnetic. It's a green mini size one that I had added my last ebay order of cheap stuff from China just to see if it was any good. https://www.ebay.com/itm/5-Color-Mini-Solderless-Prototype-Breadboard-170-Tie-points-For-Arduino-Shield/201677166530 |

I only have one that I know is from China the rest are from North American suppliers with unknown origin.I tend to be a cheap son of a gun because my just a hobbyist.But non exhibit magnetic properties and all have similar resistance of approximately 0.5 - 1 mOhm between each socket.But magnetism might not be conclusive either because they may have nickel plating. I suppose my next order from Digikey I'll breakdown for a brand name one and see if theirs a difference. Aside from a few decade counters and timers most of what i do is mostly power electronics so my experience is admittedly limited.But I would definitely check that convertors output. |
