<p><span class="h-card" translate="no"><a href="https://astronomy.city/@hendric" class="u-url mention">@<span>hendric</span></a></span> what&#39;s a vac pack?</p>

<p><span class="h-card" translate="no"><a href="https://chaos.social/@gsuberland" class="u-url mention">@<span>gsuberland</span></a></span> the key lesson i learned to get it to be this good was that (a) you use a stencil with paste, not loose balls that are fuckin impossible to get to stay in place and (b) you have to get the IC to be *really* level and flat wrt the stencil in the jig, or you&#39;ll push paste underneath it and end up with a mess of shorts and blobs</p>

<p><span class="h-card" translate="no"><a href="https://tacobelllabs.net/@arrjay" class="u-url mention">@<span>arrjay</span></a></span> afaik that one isn&#39;t used for anything, so i decided to wing it</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> I rate you 624 out of 625!</p><p>Funny story, back at ye olde semiconductor company, a customer&#39;s ops team heard something funny in one of our vac packs. They did medical devices including x-rays, and sent us an x-ray picture with a big angry red circle around the loose solder balls in the pack. Uh, oops!</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> decent job!</p><p>spotted a couple that might need some extra attention. the far left and right ones are probably ok (low solder quantity), but that middle one looks like it has an extra solder ball stuck to it and you might get a short.</p>
