If you have observed variation in the chamfer location (i.e., the chamfer position appears different from what is shown in the datasheet) on the IQD Frequency Crystal LFXTAL069404, as shown in the image below,
Please note that we have checked this with the manufacturer. Please see their response below:
The chamfer (the small angled corner on the crystal package) in the above photo is correct.
The real problem is that the marking printed on the top is not consistent, which is causing confusion.
The crystal will still work correctly electrically, because it only connects between pins 1 and 3. Even if the pick‑and‑place machine looks from underneath, it will still place it correctly.
The only issue happens during AOI stage. Because the marking is inconsistent, AOI machine may think the part is fitted the wrong way.
This can usually be fixed by programming the AOI machine to accept the part either way around for Xtal only.
