Soldering show off

[Aussiephil]

Got some TSSOP to DIP adapter boards today to do some prototype work with and had to show off the soldering job.

The whole board shown below will fit in a standard .6" wide 28 pin DIP socket.

Soldering the tssop part was suprisingly easy, the hard bit was keeping it in place to tack the first solder joint.

How it was done:
 - Spread thinly SMT Solder Paste across all the pads without being concerned if it was between the pads.
 - place part onto pads and tack a pin on opposite corners.
 - check it was still lined up really closely.
 - starting with a set of pins not tacked in place heat up a group and wipe iron tip away from part. This draws excess solder from between the pins.
 - continue this on both sides checking for solder bridges between pins.

In my opinion the use of solder paste which will ball up and flow to the pads and pins makes the job easy. not sure i could do this with normal solder.

Here's one I did... and with regular solder.

Hi Phil

Congrats

Boy you know that is small part when the traces look big

How are you eyes?

Sometimes when soldering resistors and caps that are very hard to control I will take a toothpick and dab a tiny bit of super glue on it and stick it to the part. Kind of like a handle. It helps a lot and if you let the glue dry on the toothpick a little before touching the part it is easy to get off. I also use lots of liquid flux and clean up any messes with copper wick.
