Almost all of the components on the bottom side are passives however, there are a couple of mBGA's and qfp's. I am aware that even if the components on the bottom do get reflowed, surface tension of solder will hold them in place. As far as IC's, w

I assume you talk about wave soldering. No-clean fluxes are widely used since 1987 or earlier and after all these years they have proven to be reliable. If you clean the board or not the dust bunnies etc. will still reach the board surface. If you us

The warmest spot you measure on the board is the bare laminate. It will be 10*C hotter than a solder connection.

I say: �Wave flux needs to be heated to certain activation temps which won't be repeatedly achieved with a manual soldering process. Plus, you won't burn off any residual activator as you would if the board were immersed in a solder bath.� Muse say

Its in the IPC 600 bare-board specification.

We use HASL and immersion silver, depending on the board design.
