Flip the PCB and repeat (if necessary).&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=11047&amp;AppID=18&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item><item><title>RE: Building a Voltage-Controlled Oscillator (VCO)</title><link>https://community.element14.com/technologies/open-source-hardware/b/blog/posts/building-a-voltage-controlled-oscillator-vco</link><pubDate>Sun, 28 Mar 2021 21:26:18 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:1500d240-86da-4ff8-a83d-267a857e063c</guid><dc:creator>Jan Cumps</dc:creator><slash:comments>1</slash:comments><description>&lt;p&gt;I use the &amp;quot;solder one pads&amp;quot; approach. But not one by one. i tin a number of pads. Put the components. Then solder the other sides.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;Sometimes I paste both pads, dip the component in place and reflow with the iron.&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=11047&amp;AppID=18&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item><item><title>RE: Building a Voltage-Controlled Oscillator (VCO)</title><link>https://community.element14.com/technologies/open-source-hardware/b/blog/posts/building-a-voltage-controlled-oscillator-vco</link><pubDate>Sun, 28 Mar 2021 17:58:25 GMT</pubDate><guid isPermaLink="false">93d5dcb4-84c2-446f-b2cb-99731719e767:1500d240-86da-4ff8-a83d-267a857e063c</guid><dc:creator>DAB</dc:creator><slash:comments>0</slash:comments><description>&lt;p&gt;Very good post.&lt;/p&gt;&lt;p&gt;&amp;nbsp;&lt;/p&gt;&lt;p&gt;DAB&lt;/p&gt;&lt;img src="https://community.element14.com/aggbug?PostID=11047&amp;AppID=18&amp;AppType=Weblog&amp;ContentType=0" width="1" height="1"&gt;</description></item></channel></rss>
