Have anyone bought electronic components at AliExpress?
Some time ago I bought 10 MAX680CSA from a seller and none of them worked. Later on I found one of those from a scrap board and it worked fine.
What are the chances of getting fake or counterfeit ICs/transistors from chinese sellers?
Look at attached images. How is it possible that both ICs are original if the marking typography is different? In one, "Techcode" is wider than "TD1482A", while the other is the opposite. Is it possible that a manufacturer produces various batches of the same product without a consistent look?
How is it possible that many sellers there have a feedback ratio of 97% or less? In eBay, less than 99.5% is rather average score. Why many sellers look the same with small variations in their names?
And what about eBay? Many sellers from China or HK with same prices, but at least their feedback score is much better. But is the product more reliable?
