I've just got my non-detected CT3670 back to detecting in Windows by hand resoldering the main chip, While removing the RAM sockets, I noticed that the solder on the board behaved more like lead-free stuff when de-soldering. Adding a bit of quality leaded solder made it much easier to remove. …

salvageable, get a razor and try VERY carefully bending pins apart, they dont have to be super straight, just not shorting even if you rip some pins by accident its not game over, you can dremel out outer plastic to get to the lead frame https://upload.wikimedia.org/wikipedia/commons/thumb/8/8b/TQFP …

Your right, That Thermaltake orb is laud but it does keep the CPU functioning. I never took a heat gun to it to see how hot it gets. You misunderstood, ORB mounting mechanism requires a TWISTING action while it squeezes the delicate Die of the CPU. So no, it doesnt "keep the CPU functioning", it …

Braid is useful only for removing shorts between pins, getting rid of excess solder and cleaning pads of a surface mounted chip prior putting one back. thats exactly how you rip pads off https://www.youtube.com/watch?v=0nWrx8QcNiI granted it might work better for thru hole with quality plated vias, …

I have a project where I’m trying to de-solder a 486 CPU from a PCB – its directly soldered in, through-hole, to the PCB, then solder in a 486 socket. I was wondering if anyone had any tips on how to go about this solder pot/bath is the easiest/quickest method, but I suspect you wont have access to …

Via 693A is a bad performer regardless, but that matters least with as high an FSB as possible with a relatively low multiplier. That P3-733EB would do fine. It would perform only marginally worse than a P3-700E would on a BX board (such as that P2B). Is the 693A really that much slower, that even …
