Re: Swapping chip on hot tub motherboard.
Why? those are generally used to pull a chip from a socket. I'd be willing to bet they would be too thick to get under the IC I was removing. I had to search for something thin enough to get under it and still be strong enough for the job. Plus, I didn't have to wait ten days for it to be delivered....

Re: Swapping chip on hot tub motherboard.
I want to thank everyone for their input and advice. I scrapped my piggyback idea and devised a spring loaded puller to aid me while heating the other side. I mounted it in a hobby vice where I could view it edgewise. I started applying heat and in no time started watching the legs slowly sink into the board. The last couple of legs got bent a little because it wasn't pulled straight up, but no big deal. My redneck chip puller might look a little crude, but I only spent ten minutes making it, and it worked!...Last edited by blufx; 06-15-2016, 09:56 AM.Leave a comment:

Re: Swapping chip on hot tub motherboard.
Thanks, but I'm going to stick with replacing the chip on a board that I know works....Last edited by blufx; 06-14-2016, 01:33 PM.Leave a comment:

Re: Swapping chip on hot tub motherboard.
Thank you, but I'm going to disagree. There are six relays very heavily soldered in place....Leave a comment:

Re: Swapping chip on hot tub motherboard.
I'm trying to dream up a method of holding all in place. I might have to resort to some redneck engineering. I'm picturing only a couple or few seconds per leg solder time.
Because nobody likes my piggyback idea, I'm also thinking of a way to apply an upward pull on the chip while I warm it on the opposite side with a heat gun....Leave a comment:

Re: Swapping chip on hot tub motherboard.
The relays are corroded. It was subjected to weather for years....Leave a comment:

Re: Swapping chip on hot tub motherboard.
My tub has a single two speed pump. The other tub had two single speed pumps. Exactly the same board with different cycle instructions.
Thanks for your reply. I intend to reply to R_J also, but later. I'm tired....Leave a comment:

Swapping chip on hot tub motherboard.
Hey guys,
I'm replacing the motherboard on the hot tub. The board I bought is identical except for the controller chip. I'm not well equipped and don't want to damage the chip, or the other board. Rather than attempt de-soldering both chips from the boards, I was thinking about shearing the legs on the chip I want to use close the board, then shear them close to the chip itself on the other one. Make sure everything is clean, and solder the legs to legs. Is there any reason this won't work? The chip with the white label is the one I need to put on the other board.... -
Re: New Members - please post your introductions here
Hello, new member here. I was searching for BIOS password help when I found this site. I work at my home repairing computers. I'll be back to give more details about myself. After just a quick look, I can see there's lots of information here that I can use.Leave a comment:
