<p><span class="h-card" translate="no"><a href="https://chaos.social/@gsuberland" class="u-url mention">@<span>gsuberland</span></a></span> ... oh, so simple and effective</p><p>anyway i found these impossible to use with the loose balls because the balls would not stay in place</p>
<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> ah yeah I usually kapton tape the stencil to mask off the extra holes.</p><p>I have a very similar frame, and a fancier one somewhere which I can't currently find.</p>

<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> you missed a spot (already pointed out - this is a shitpost or a shit post take your pick)</p>
<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> doing the solder balls by hand is an extreme headache, but you can get BGA reballing frames reasonably cheaply where you clamp the part in the lower section after applying a little flux, clamp the stencil in the upper section, they're spring loaded so it presses the stencil down, then you pour a ton of solder balls into the top and roll them around, then it has a little channel in the corner where you can tip the excess balls back into the container. pretty painless.</p>

The packaging holds and positions the parts precisely so they can be taken out and assembled using pick-and-place automation . ("Vac" for "vacuum-formed" perhaps?)</p>
<p><span class="h-card" translate="no"><a href="https://mastodon.social/@whitequark" class="u-url mention">@<span>whitequark</span></a></span> start with a stack of trays holding parts. You put a couple of dessicant packs on top and seal it within an electrostatic bag. Its not really vacuum sealed, but thats what I always call it.</p>
