AM26C31:AM26C31IN 4倍差ラインドライバ　9/24　注文番号：T01785141

Hi Okada,

Translating your question roughly:

AM26C31:AM26C31IN Quadruple Differential Line Driver Order # T01785141

"I bought a device from TI.com, but the surface of the device is rough. If you have problems with your device, check captures and ask for advice?"

Are you asking a question about the surface of the device package?  It looks slightly roughed up, but I don't think this will affect the electrical characteristics of the device too much. Is that how the part initially arrived when you first bought it?

Regards,

Tyler

こんにちはタイラー様
部品の表面は、部品が到着したときからあれていました。品質に問題ないのか答えてください。

Okada,

There shouldn't be any problem with electrical characteristics of the device even though the package is slightly roughed up. How long have you had the part? Did you order multiple? And if so, were they of all the same quality - rough up surface? 

Regards,

Tyler

6000個購入しましたが、荒れたデバイスは、100個以上あります。

まだ全てを検査していません。

この様な状態の物がどれくらいあるか分かりません。

おそらく数百個はあると推測します。

品質に問題無いとの回答を受取りました。

この回答を品質保証の根拠にします。

この部品は使用していきます。

Okada,

All parts that leave TI facilities are production tested before sent off to the customer. This means that all parts that leave our facilities are electrically sound. I have contacted our Quality Engineer to check on the reason for the package not being so clean upon arrival.

Okada,

Did you see this roughness on the packaging before or after soldering to the PCB? Quite possibly, there may have been some excess solder flux that got on top of the device. Or maybe some process during soldering caused the issue.

提示した写真ははんだ付け後の部品でした。

しかし、未使用品を確認したところ同じ状態でした。

はんだ付け前にパッケージの粗さが見えます。
