Folks,
I've designed and implemented two product prototypes using the QFN package for the nRF51822. Now I need to move to the BGA version to shrink the designs. The nRF51822 Product Spec version 2.0 says: > 11.3 WLCSP package > Documentation for the WLCSP package reference circuit, including Altium Designer files, PCB layout files, and PCB production files, can be downloaded from www.nordicsemi.com. Hmm.... where? If I look for reference designs on the main website, all I can find are Reference Designs for specific dev kits and *products*, e.g., the nRF51822 Beacon. If I'm interested in a design for the WLCSP package, I have to poke around to find out which *product* uses it. And to add insult to injury, I have to buy one of these *products* to get access to the design files. Hardly a significant cost in money, but irritating and a waste of time. I have to order one, pay for premium shipping, and then enter the product key. And if I want to check out some variations, e.g., in he remote control, repeat the process. My daughter, the lawyer, would call this an example of "bait and switch"*. I would never say that :) but as a former manager of a developer support team at a major technology manufacturer (named after a fruit), I wonder what the reasoning behind this process is: too small a cost to keep out the riffraff and too much of a bother to facilitate adoption of your products. Sigh.... off to place a Digikey order, Mike *Kristin, you need to be careful in your responses, too. In the posting referenced below, you say "*You can download reference designs for the nRF51822 for both the QFN and WLCSP packages on the nRF51822 webpage, under the downloads tab, in the reference layout section.*" without noting that they're locked without a product key ;)
