I am soldering the cougar control board and i am having lots of trouble with heat. Most parts and holes get soldered straight away with my (25w, 750F) radio shack iron. But the legs/holes that are connected to the large copper ground planes will NOT heat up enough to melt leaded solder. I went out and bought a 50w 900F Velleman soldering "station" (cheap $20) and cranked up to 900F it sometimes melts the solder if i hold it on the joint for 30 SECONDS OR MORE. C'mon - shouldn't an iron melt solder in a few seconds on this size board? Do i need more watts or do i need 1000F to get everything hot enough to solder?

I cannot finish this pcb until i get an iron that works !!!
