Solder shorter parts first...then when you flip the pcb over the parts that are not soldered yet will not slide away from the board.
Then next tallest, etc.
Then next tallest, etc.

Hey, I just inherited a 85-90% completed DAC-38 board
all I'm missing is:
CS8414 chip (X1)
74HCU04 chip (X1)
SSM2142 (X2)
EL2044 (X4)
and especially any kind of schematic...
can someone help me with any of those, all the parts are now obsoleted by mouser and the others....
I could probably find replacements but for the schematic its quite hard.
any help would be appreciated.
