Advice for soldering &lt;strong&gt;leads&lt;/strong&gt; to that? It&amp;#39;s really ambitious and it makes me anxious just to think about it. I can just imagine getting one wire on and it falling off while doing the next one. &lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;What I think you&amp;#39;ll need:&lt;/p&gt;&lt;p&gt;Dentist&amp;#39;s Tools - you know, the thing they scrape plaque off your teeth with. If you don&amp;#39;t have one, a sewing needle or the tip of very fine tipped tweezers will work.&lt;/p&gt;&lt;p&gt;Hot Air Station - narrow tipped&lt;/p&gt;&lt;p&gt;Microscope - as mentioned above.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;While looking under microscope:&lt;/p&gt;&lt;p&gt;1. Use the dentist&amp;#39;s tools or equivalent to put paste on the pads and thermal ground. Just dip the tip into the paste then touch the pad.&lt;/p&gt;&lt;p&gt;2. Put the chip in place&lt;/p&gt;&lt;p&gt;3. Hold the chip in place lightly with the dentist&amp;#39;s tools while applying a very low flow from the hot air gun. Use an appropriate temperature for your paste. Careful to heat the chip and not the tools. I.e. don&amp;#39;t burn yourself. You obviously can&amp;#39;t use the sewing needle for this, so I hope you have either the dentist tool or the tweezers.&lt;/p&gt;&lt;p&gt;4. Remove heat, then the dentist&amp;#39;s tool.&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=17522&amp;AppID=115&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item><item><title>RE: Shaky hands and precision soldering do not mix</title><link>https://community.element14.com/challenges-projects/design-challenges/wireless-power-ii/b/blog/posts/shaky-hands-and-precision-soldering-do-not-mix</link><pubDate>Mon, 14 Apr 2014 19:42:56 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:13bbb66e-ea69-41fc-bb35-16ee91ceef9f</guid><dc:creator>DAB</dc:creator><slash:comments>1</slash:comments><description>&lt;p&gt;Just wait until your eyesight fails and you get arthritis in your hands.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;That&amp;#39;s when you know its time to let others do these kinds of things.&lt;/p&gt;&lt;p&gt;DAB&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=17522&amp;AppID=115&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item></channel></rss>
