When it comes to soldering the ic to the board......Do Not be tempted to solder all the pins on one side one after another...... If its a qfp (quad flat pack, bit like mfi furniture..... :lol:) solder the 4 corner pins first to secure to the board nice and level.....Then solder alternate pins on each side.....This will prevent the chip from overheating...if you are a bit overzealous with the solder, use solder wick to draw off the excess solder...dont use a solder sucker....risk of damage to chip or pcb..... |

No, I've got a 5"magnifier lamp with a shedload of LED's round the edge. :thumbup: It makes a hell of a difference, those 0805's looked like house bricks. I think if I ever had to solder 0603's again I need a smaller chisel tip for the iron. the smallest one I have is 2.4mm and I could get a 1.2 or a 0.8. Roy. |

I would suggest the 0.8mm tip. That's what I have on my Weller. Even that seems too big sometimes and I don't even do SMT. Dave |
| wheeltapper:
Hi Dave, I've just ordered a 1.2 and a 0.8 straight after my last post. the IC lands on the practice board are only 0.8 so anything bigger is going to be too big. Roy. |

Here you are, Rob ... PCB for your PSU, not including diodes & LEDs .. Done on ExpressPCB. Took about an hour. Dave |
