Sockets for easily breakable components
Posted: Sat Aug 03, 2013 7:40 am
I tested my completed oneTesla for the first time yesterday, and like some others I blew the IGBTs and two of the MUR460 diodes. While fiddling with testing and desoldering these components today, it got me thinking:
Why not put the components that are likely to break but difficult to replace (mainly the IGBTs) in some sockets or screw terminals. That way they can be swapped super easily.
I've seen on this forum that a lot of people break their IGBTs during early testing, and the wording in the manual makes it seem like they can easily overheat and break even during normal use. If they're so fragile (or poorly protected?) shouldn't they be easier to replace?
Besides, desoldering and resoldering several times is likely to mess up the solder pads so that the whole circuit board must be replaced. It would be great to reduce this risk too.
Is there any technical reason why this is a bad idea? Please let me know your thoughts!
