williB said:Hey guys , I've recently purchased some IRF6609's
They come in DirectFet packages , Which are Leadless flat rectangles..
My question is , How would i solder them onto the board? Solder paste?
An oven?
Any recomendations?
cant do that , i've allready bought them.. Plus they are the ones i want to use..Nigel Goodwin said:williB said:Hey guys , I've recently purchased some IRF6609's

As far as I'm aware (and I don't have equipment to do them) you need to simultaneously heat both sides of the board to an accurately controlled temperature, presumably you use solder paste? (or pre-tin both board and component).
I have a friend who's got all the gear, he replaces multi-hundred pin BGA (Ball Gate Array) in digital satellite receivers.
My recommendation would be to pick some easier to handle FET's!.

they have only 2 milli ohm resistance @10 V Vgs..

Optikon , Oznog and Nigel ,i am pretty sure that i can work with the 6609's , tommorow i am going to try the toner transfer and etch a board or two..Optikon said:williB said:cant do that , i've allready bought them..

Did you consider paralleling two (4 milli-ohm RDSON) Fets that are easier to deal with. I know you can get down to 4milliohm in D2Pak.
i'm not sure what you mean ..??It is something I had to do all day when I worked as a prototype tech................If you solder one part on and the clamp a heat-sink to the board between the two peaces you will have no trouble with temperature creeping along the tracks.
oh , i get it now..rigdoctor99 said:It's not hard to understand. You form a heatsink in order to disipate the heat away from the commponents that you have already soldered to the board........................

i ordered some IRF3703's that come in a TO220 package..
the IRF3703 has a RDS(on) (on resistance) of just 2.8 mOhms ..
a Vgs of 20V
a max current capacity of 210 Amps.. :lol: depending on the junction temperature
i cant wait till they get here.. 8)
