There are two ways to do this:
One is to buy an expensive, specialized test socket with pogo pins and a clamshell, from eg https://www.loranger.com/loranger_edc2/html/index.php https://www.loranger.com/loranger_edc2/html/index.php or similar manufacturers. This is what you'd do if you wanted to do a burn-in test of some exotic amplifier or sensor, or to set up a small-scale assembly line and custom-program hundreds (not 1, not thousands) of these chips, and could write off a $100 standard socket or $10,000 custom socket as a cost of doing business.
The other way is to just use a hot-air gun to desolder the WSON from the motherboard, use some Chip Quik to temporarily solder it (or an identical chip you bought for $0.50 from Digikey) to a breakout board, program that, desolder it, then reattach it to the motherboard.
Of course, the third way is to have the manufacturer or the distributor do this for you.
- etiam 4y agoThanks! It's great to have some approaches and terms to structure around and as a bonus you've offer a few glimpses of a world I don't know enough about. I was hoping there would be an affordable option for programming in place, but the examples I've come across so far seem uncomfortably fragile ( https://flashrom.org/File:DIP_socket_as_SOIC_clip.jpg https://flashrom.org/File:DIP_socket_as_SOIC_clip.jpg ), so I guess I am most likely in for reviewing some heat implements and trying to refine my soldering skills on a more expensive board than I'm used to. Will have to give more consideration to option three in the future, though in principle I appreciate having the access to keep modifying if needed, so maybe more importantly be more careful with the hardware selection.
