Hello, I was wondering if anyone has experience and thus suggestions for good soldering techniques of those tiny, 603 and 805 surface mount caps, resistors and inductors?
What I used to do, is place the part on the solder pads, heat the pad and then apply solder. however, I found that solder leaks underneath the part, and either lifts the part perpendicular to the board or lifts it parallel, with a small air gap in between. I only have two hands, so i have to pick between the iron, tweezers and the solder.
I have been experimenting by applying the part on the pad, apply pressure to the tweezers and heat the pad so that the tiny solder on the pad locks the part in place. I then apply the solder, to get a nice, uniform flow on the pads. with no air gaps and a straight connection w/o shorts and mess.
I tin the solder iron point and i use non-lead, water soluable solder with flux. So far I have been getting good, solid solders with it. before, I was monkeying around with the part trying to correct its position and burning the board or my fingers. I also use solder wick, but I found out those plungers suck solder much better, but is a bit messy with solder shavings coming out.
The only complaint I have is that this procedure takes an extra step to implement. I can sometimes pull a tech to the side to do the job for me, but I'd like to get to learn how to do it effectively by myself.
Any tips?
