Well the host arrived yesterday. Not the greatest quality but really this is more of a practice for me as I haven’t attempted soldering 7135 chips yet.
Just soldered the chips then and have to say I am pretty stoked for my first time effort!! I bought two driver boards and a bunch of the 7135 chips in case I stuffed it up but it looks like I am not going to need them this time around! On a side note, I’m pretty impressed with the camera on my S4 for taking these close up shots.
For reference for those who haven’t seen the size of these 7135 chips before, that is a pen tip…
With good flux, it's hard to get the solder to not jump the gap. Ain't surface tension an amazing thing?
And don't forget gravity, you can use that as a free helper. Ordinarily adding a blob like this to a spring the solder will either fall down through the spring, or wick down the coils. Add a bunch of solder, let it freeze, flip upside down and touch the side of the spring (so the iron doesn't suck up all the solder), the solder will flow down and make a nice even rounded mound. Hold until it freezes, then file a flat spot for more contact area.
How long? Until the dome floats off. I don't know about the thinners, but with gasoline you can leave them in virtually forever without damage. Break the outer skin of the silicone dome with sandpaper or light cuts from a razor and it'll happen a lot faster.
