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 |

| thanks for the tip cirvin and guys...I'll try some of them and report back... |

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

I wrote an SMD soldering tutorial in the diyaudio wiki...
The article covers SMD rework, which is somewhat broader than just SMD soldering, but the basic techniques are all there, in complete detail. Click on the links to see all the photos...
DIYA Wiki - SMD Rework
The main thing you'll need which you typically don't use in through-hole construction is liquid flux. Get some liquid flux and a needle dispenser, along with a fine tip for your soldering iron, and you'll be all set. Hope you find the tutorial useful... :)
PS - you do not need to use (expensive) solder paste at all... solder paste is intended for automatic assembly machines. You can assemble small circuits faster and easier with extra-fine normal solder and liquid flux, and the parts will be exposed to less heat. |
