I've had good luck reflowing this by hand. http://www.johansontechnology.com/rfbaluns and search for Nordic.<br />* Have you tried oshstencils.com? Not sure what shipping would be like to Canada, but the quality is good.Christopher Masonhttp://hg.cmason.com/nrfnoreply@blogger.comtag:blogger.com,1999:blog-831309579862171927.post-37355575255734528322013-07-26T09:38:05.795-07:002013-07-26T09:38:05.795-07:00Hi Janek,

This is working pretty well. I think I'm going to stick to this instead of pursuing the ST Balun further. I had the space to spare on the board so it wasn't a major loss.Keith Wakehamhttps://www.blogger.com/profile/04750593468902337123noreply@blogger.comtag:blogger.com,1999:blog-831309579862171927.post-65547023541674207102013-07-26T07:54:17.941-07:002013-07-26T07:54:17.941-07:00At a hobby level, it's easier not to use solde...At a hobby level, it's easier not to use solder paste with small-pitch BGA devices like that balun but just use flux. The balls provide sufficient solder to attach the part. Use a "tacky flux" to get the part to stick before you reflow.Janek Mannhttps://www.blogger.com/profile/16811430647229780115noreply@blogger.com
