OT: Qualcomm to send NXP to the chop shop

Yup, it's huge. The Hamburg, Germany fab is supposedly the biggest waferfab for discretes in the world. Add to that the labor-intensive packaging fabs in Asia, where most of the value is generated and most employees work, it becomes plausible.

That's right, and I don't understand it. I know NXP sells the great BF862, but I don't know where it's made (not in one of their two discrete fabs), it's not in their selection guides, you won't find it under "Applications" nor under "Products" on the website. The website only admits to its existence if you directly enter the type number in the search box.

I should try and find out sometime.

I have stored that from diyaudio.com:

====== Thread Home > Forums > Design & Build > Parts NXP BF862 warning

I got two batches (100 pcs. each) of BF862 low noise n-channel jfets, from two different providers (DigiKey Corp. | Electronic Components Distributor | United Kingdom Home Page and Mouser Electronics - Electronic Components Distributor). Both are 100% genuine NXP parts, the only difference being the origin. One batch is marked 2Aw (w stands for China) and the other 2Ap (p stands for Hong Kong).

While they both have the noise floor @100KHz as per the datasheet (~0.8nV/rtHz), the Chinese parts have significantly larger noise corner frenquency (~2KHz) compared to the HK parts ( , somewhere near the top. I have bad cell phone reception at the moment and cannot load the flickr page in finite time.

Interesting, thanks. I'm normally using them in TIAs and bootstraps where the 1/f noise doesn't bother me much.

Note that the "Made in..." only says where the final assembly step was done (i.e., where die was moulded in the package), not where the die was made. Otherwise almost all NXP small-signal diodes and BJTs would be "made in Germany." It's very possble that your parts came from different batches from the same waferfab, and some happened to be assembled in HK and the others in mainland China.

You've some nice pictures of a trip to the west and north of Scotland there - I hope you enjoyed it (many tourists don't venture further north than Edinburgh).

Which did you enjoy most between the Ring of Brodgar and Stonehenge? There's been some very interesting archaeological finds in Orkney in the past few years.

I see you visited Mull - did you have time to go to the outer Hebrides?

Here's a video of Karine Polwart in the Italian Chapel

Brodgar.

OMG. Stonehenge was pure chaos. One day before solstice, there was a flood of neo-pagans etc. The parking space is now 3 Km from the henge, with jam already on the road that passes Stonehenge. Then there was a queue of pedestrians for all of the 3 Km and back. We gave up. The Stonehenge photos have all been done blindly from the moving motorbike in the stop & go from the road that passes by.

Yes, I did inspect some flats in Scara Brae that are vacant since 5000 years :-) and some other places. Orkney was great.

No, maybe next year, and also to Skye.

Stonehenge is terrible now: "look don't touch, please keep moving", which is a great shame. When I was a kid people clambered all over the stones and ate their picnics on them.

Fortunately there are many other stone circles and barrows where you can still do that. Near Stonehenge there is Avebury (Europe's largest neolithic stone circle), West Kennet Long Barrow, and Silbury Hill (the largest man-made mound in Europe).

If you are up there, consider looking in and around Kilmartin.

Being familiar with the circles in Scotland I was a bit dissapointed when I visited Stonehenge, given it's the most famous circle in the UK. It's so small compared to some others I couldn't help but think of the stage prop in the film Spinal Tap.
