The MC33886, might work, though itís diagnostic functions are a little different. Maybe could build a little adapter PCB for other h bridges.
damn this sucks. I am just now feeling comfortable to try this since I got my new soldering station with a adjustable heat flow gun with assortment of attachment of tips. was going to start practicing desoldering chips and resoldering with older paste and heat flow.

Kassleperformance still offers this service so i wonder where they get their h bridges from. I may hit up Chris to see if he does this as well.

They may have just bought sufficient quantities to not worry about it for now. Or they're using Chinese replicas. I've personally had bad luck with them (to the extent that one actually permanently damaged one of my DMEs), but perhaps some are okay.

Also you need some serious heat to get the solder underneath to flow - the little soldering station is not sufficient (at least without preheating the board and such)

well poop

this was the soldering station i got on amazon.



  • Specifications:
  • Voltage: 110V/AC:
  • Storage Environment: -20~80įC:
  • CE approved:
  • Power Consumption: 270W (Max.)
  • Pump: Diaphragm Pump
  • Capacity: 24L/min (Max.)
  • Leakage Voltage of Iron Tip: <0.5mV Standard Iron Tip: AT-900M
  • Hot Air Temperature: 100 to 480C
  • Tip of Iron Temperature: 200 to 480C

so far it has fit the bill for soldering TIP usage as well as voltage usage.

i was going to crack open a used non M cluster I had and give my try at removing the M35080 chip in it as practice run and resoldering it back to the board with intact legs and solder paste.

It's fine for stuff like the M35080. Problem with the H-bridge is it has a metal plate underneath its body that's meant to be soldered to the ground plane of the PCB so that it can use the PCB as a heatsink. That means you need quite a bit of heat to loosen the solder

We use this at work, and it's amazing. We sold our Hakko...

Huh, that price isn’t terrible either

Couldnít one theoratically substitute soldering with silver paste instead of solder under the chip for heatsink??

Probably. It won't conduct as well as solder, but might be good enough. Or possibly a low melting point solder like ChipQuick would be fine for the underside.
