Back in my happy place and looking at how to hand solder a couple or Luna boards. The parts from LSC aren't here yet but I have the ICs.
FPGAs on. Preheated the board to 150C and then whacked with the Quick 861DW.
May need a referee call on whether I bumped the second one too much and bridged the balls but I reckon I'll get away with it.
USB controllers aboard! Combination of my usual lazy "tin the pads and flux it up" style and also solder paste for the ground pad. Actually the first time I've used solder paste "for real" - hope it works! Ideally I'd have had less Amtech flux on that pad but hey.
That'll do for today!
Quite enjoyable to do two boards at once. I'm opening the Digi-key bags as needed and then putting any excess parts into these handy Adafruit "Snap" containers.
Love that with hand soldering I can stop for a break anytime and spread out the enjoyment :-)
My first ever bodge wire!!! đŸ„ł
Part with ever-so-slightly wrong sized footprint. Has to connect with the pads on the right but I tied this pin to ground on the left.
Only five wires to go here, and then three more such parts...
Not as easy as certain people make it look !
s/five/seven/ I also tried standing the part up on its side and hand-soldering the pads on the bottom to the board but didn't get working joints so I'm trying the bodge wire approach.
I have a wire pencil but I think I need to cut lengths with a scalpel and then place them.
Since @GregDavill demonstrated that a bodge isn't needed I resoldered these bits with the simple "tin, flux, hot air" method. Half a point deducted for having to reoriented one after soldering â˜ș
RAM went on very nicely indeed.
Flash chip is big enough to break out the Ersa Nano. That's a real treat, I love working with that iron. I don't reach for it very often because most parts are too small.
I've placed the preheater and PCB holder on this yellow steel plate. I put ball bearings underneath so that it all slides and rotates easily. This would be too slippery but for the ergonomic armrests that take the pressure from my hands and arms.
Tickling a playful little MCU onto some loosely tinned pads.
Camera work is lacking (damnation that I chose the wrong relay lens!) but here's my most successful clock oscillator soldering to date. Trying to make each corner even and (superstitiously) avoid the thermal stress of hot air.
Hey anyone know if I put this diode on the right way around? ( @GregDavill?) I couldn't decipher the markings so I did my best based on schematic and multimeter. Maybe need to turn it around...
Chasing a fleet of 0.1uF decoupling capacitors around the back side of the board...
