I troubleshoot & solder all day long, through hole & SMT (surface mount technology) PCB (Modules & Panels)
Yes there is a soldering machine Its called "wave soldering" all components are loaded into the pcb using other machines that are programmed to load the components into the right circuit/node then humans load all other components that the machines cannot load which are many) then the pcb with the components is passed into the wave solder machine which heats everything, including the board, then the bottom of the board travels over a molten hot solder pool that just skims the bottom of the board & components which instantly solders everything, the solder only sticks to the metal & not the pcb, then it travels out to a slow cooling station, Problem is that the machines & the humans loading all the components are not perfect so then that's where I come in, we locate solder bridges (shorts), overvolted circuits usualy a resister missing or wrong ohm in circuit, components loaded in wrong direction in circuit, IC's with bent or lifted contacts ETC ETC..........
So first you have to locate the problem then desolder components & replace & solder cleanly then benchtest some of the modules & panels Its Interesting & tedious work sometimes I want to snap the freaking modules in half cuz it can be frustrating you have to have allot of patients which sometimes I run out of
Some tools we use are
Dental Pic
Exzacto Knife
Small Brushes (that we trim very short for cleaning flux off solder joints & pcb with Alcohol.)
No-Clean Liquid Flux
Rubbing Alcohol
Soldering Iron
Desoldering tool (basically a soldering iron that has vacuum in the tip)
Its tedious work been wanting to do a vmod on my ic7g but I cant afford another one so I'm always reluctant to do it.
At work if I botch something there's more of the same part, at home If I pull a trace or burn an IC Ill be offline for a good long while
This is an awesome mobo would hate to screw it up
Maybe Ill get some backbone & take my mobo to work & do the vmod after hours.
I really need to do the modd cuz my ram is starving for voltage
