Re: First smd hot air soldering

Bad soldering paste is 'very' conductive, so mainly in chips that has a good heating during work, may cause several problems - if there's soldering paste under the chip, the heat will melt it and it will 'short' the chip pins.

I use soldering paste while extracting the chip, after that, I use some more only to fix the soldering over the pads. So I clean all the remain soldering paste. When I solder the chip, I don't use soldering paste(as will remain some under the chip).

Re: The Future of the Desktop PC

Here we have many stores - the commercial sector in general - that have several machines and seems they will always be there - it's less costly to make a good repair than buy new ones.

Re: New Members - please post your introductions here

Hi! I'm from Brazil and found this forum while searching for motherboard repair (chip level) materials.

I'm only a hobbist but was amazed when I fixed my motherboard (ressolding the I/O Chip) and now I wanna to improve my skills in this area as in my region nearly 99% of the technicians work by parts repair, not chip level. Sure I'll have many great info here and if I can, surely will retribute.

So, a great handshake to all.
