This board came out much better than last week's so U get a photo journal.
Soldered the passives by hand first, then tinned the actives, tacked the actives, & reflowed. U can probably get better placement by using 0.254mm leads to pinch off the surface tension.
This was a conventional oven at 450 for 90 seconds. We've mastered conventional oven reflow, but the lead poison seems to be kicking in.
