Hi all,
Just like to share a quick and easy way to rework smt and make all our life easy again!
found this company selling an alloy called chipquik
www.chipquik.com
They call it smt chip removal alloy .It makes it very easy to remove smt chips by lowering the desolder temperature of the chip .
To melt the lead free mix ,at least 215 degC needs to be applied ,which can damage old boards and chips,if not controlled properly. Chip damage can occur at around 255 deg C.
......watch the demo video on their website.
The trick is that chipquik mixes with existing solder and desolders all the pins at once lowering the overall temperature that we need to apply to remove the chip to 150 deg C.
No damage to board and chip !
Life can be simple again !
Hi,
Does this stuff leave any residue behind?
Thanks.
It does leave residue but its easy to clean .The molten solder mix can just be dragged to an empty area of the board.You can also solder wick it off.
It's important to clean it all off or it will affect the resoldering of the chip.
