SMD soldering

li_gangyi · 20th November 2003, 01:11 PM

Hiyee,
As above...I wanna try soldering SMD stuff...but I've no PCB production facilities...as SMD requires quite few parts ( In my design) I've seen people prototyping with a blank piece of PCB and a scapel (small kinife) to cut and isolate small pads...I'm wondering how to solder these small parts and any tips I might wanna try??

It's not very hard if you have a good pair of tweezers and a small tip on the soldering iron.

The tricky part is prototyping as you describe it. It may be easier if you use some Vero-board or something.

The pcb below is soldered by hand with simple means.

But vero Board has got tracks that are too thick for SMD use..what can I do?

Why don't you prototype with hole mounted parts first and then make a pcb with SMD parts. That's what I do if there are equal parts hole mounted-SMD.

I'm sure there are some suitable SMD prototype boards on the market.

the part that I have in mind (MAX886) does not have a DIP varient...so I'm kinda stuck...

on smc, i would cut out a piece of perf board the siz of a dip chip, take the smc component and solder conecctor wires on the smc pins, then to th outside of the veroboard where you have mountd pins. then you can trat it like a dip chip

This may be a good way to learn.

There is a good tutorial on SMD soldering in the June, 2000 issue of the Encoder, a publication of the Seattle Robotics Society.

pretty cool...but I'll be needing the PCB...and I dun have one...boo hoo....
