   Back side of the line card is pasted! Used my new... 8 8 inch i think? stainless steel drywall knife with great results.

   Also running low on solder paste, I only have what's in the syringe on the bench now. Deep storage in the fridge is empty.

     @azonenberg I want a PnP machine, mainly so I can stare at it while it works

     At some point I'm definitely going to have to start thinking about PnP-ing some of these bigger boards. My designs are already beyond the point most people would have given up on hand assembly.

     This one has a touch over 600 components on it. Given the time I'm probably going to try and finish the back side but not do the front tonight.

     Minor print defect in the very corner, probably insufficient paste at the edge of the array.

     Tried to tin the pads with an iron but the board had too much thermal mass. Couldn't use preheat or hot air because board was already pasted.

     I did the best I could, it'll probably bridge but I can fix it post reflow.

     @jaseg @jpm Yep I'm honestly thinking of just machine placing 0.47 uF, 4.7 uF, 33R, 470R, 1K, 4.7K, 10K. By volume that's probably 80% or more of the parts on one of my typical designs.

     @jpm I'm never going to have one here, no space.

     I have friends with a shop across town that have, I think, a LumenPNP. It's a WIP, they dont have it working reliably yet. May bring some of my designs there for hybrid placement (e.g. robot the 0402 passives and do the rest by hand since it's less work than setting up feeders for a single part)

     @azonenberg @jpm I think the feeder setup time is a big issue for one-off prototypes. If you have some odd component like a 9k1 resistor on the board once, placing it by hand is faster than setting up a feeder. At the cost of even the Lumen’s feeders, having a couple decades of E24 already on feeders is very expensive.
