Need some soldering help

[Chu]

Hello all, I need to solder an IC in an SO-8 packets onto a PCB. For those who don't know - an SO-8 package is EIGHT pins in 5.08mm x 6.2mm x 3.18mm. Can anyone offer me advice, or know if they sell sockets for these?

carefull with the heat don't over heat the chip or the board.Use a small fine tip and drink no coffe before hand and use a large lighted magnifying glass.I replaced a 24C02 on a motherboard for a laptop.If you need to remove the old one do a search for quickchip and get their free sample..it works great

You really need to use a low-power very fine tipped soldering iron, and very fine solder wire. Make sure you have plenty of copper desoldering braid to remove excess solder.

I've done lots of SOICs and 0805s by hand - and it was much easier when I changed soldering iron to one with a 0.12 mm bit.

Line up the chip with the lands on the board. The solder one of the corner pins. Check the position and solder the opposite corner. The solder the rest.

One thing to watch for is that the surface tension of the molten solder can pull the chip out of position when you solder the first joint. You should hold it in position with a clip while soldering. Another way (not as good), is to put a big blob of solder on one of the PCB lands, and then position the chip, and reflow the solder blob to make the first join.

If you can get ahold of a hot air soldering station, and some solder paste, it should be no problem. Hot air soldering is SO easy and fast, you will never want an iron again.
