【正文】 :1的比例混合而成的溶劑）來清洗該標志，結果如右圖所示，標志已被洗掉。The markings wiped off of this part easily also. One thing to note about Maxim, in particular, is that they have not marked their parts with paint since at least before 2002. They only etch their parts. In this case that did not help us because the parts were made in 2000, but if you receive a Maxim part painted that has a date code newer than 2002 you have a counterfeit. 左圖IC芯片的標志也很容易被擦洗掉。關于美信，要特別注意的一點是，美信自2002年起，就再也沒有用面漆來給IC芯片做標記，而只是蝕刻標記。但是，左圖這片來自美信的IC芯片是否是仿冒品，若單憑以上那個證據，我們無從判斷，因為該芯片的生產時間為2000年。但是，如果我們收到的是產于2002年后的，卻用油漆作標記的美信IC芯片，那么這片芯片肯定是仿冒品。ConclusionAfter reading this document in it’s entirety you will have a much better chance of detecting counterfeit electronic ponents.

The reliability of these parts is suspect. Thedocumentation received with these parts did not include certificates of conformancefrom either the previous distributors or the original manufacturer. (Parts are pliant with OCM parts, they REUSED)從線路板上拆卸下來的被回收利用的SRAM靜態(tài)隨機存儲器，在自由市場上被當做新品來銷售。這么一來，消費者就開始懷疑裝有這些SRAM的IC芯片的可靠性，因為隨同這類IC芯片一起寄過來的文件并不包括出自經銷商或原制造商的質量合格證明書。（這類IC芯片符合OCM認證，但是，芯片內的SRAM已被回收重復利用）Device Bottom Side Device Top Side IC芯片正面IC芯片背面 A DPA revealed that the internal semiconductor die did notmatch the supplier listed on the packaging. It should be noted that thesupplier listed on the packaging stopped manufacturing this product in 1997.DPA透露說，IC芯片內部半導體鋼模標記與供應商封裝標記不符。值得注意的是，封裝標記上標明的供應商已于1997年開始停止生產該類IC芯片。Package Marking 封裝標記 Die Marking鋼模標記 Counterfeit parts that failed a programming 。Counterfeits had a three line marking sequence while the known左圖仿冒IC芯片有3行標志，而真正的IC芯片只有2行標志。good parts had only two lines of marking.Counterfeit Part with three line marking.
