PCBs with solder pads on both sides - VS - one side
Posted: Thu May 17, 2018 1:52 pm
Hi brainstrust
I have been working on a DIY project with 3 PCBs...
2 of these have solder pads on the back (green side of PCB)
and the power regulator PCB has solder pads on both sides
Now, greanted i'm a beginner, but i dont think i'm that terrible at soldering...
i'm using a 40W solder station from jaycar, not amazing but i figure it does the job like this one:
https://www.jaycar.com.au/40w-temperature-controlled-soldering-station/p/TS1620
When i solder the single pad PCBs...my wetting angle on my joins is woeful...
even when applying flux from a fluxpen. I've even tried lowering heat on the iron to see what difference it makes, and all that happens is my iron just sticks to parts or the solder pad rather than melt solder.
When i do the same technique on the double solder pad...wow...the difference is light and day...
my joins are perfect and solder flows through to the front of the PCB making an awesome connection.
How concerned should I be about wetting angle in general, and my circuits working as designed??
I guess if i test the project and it works as it should I'm guessing its OK...
but i moreso would like to know of others experience
