Hobby CNC Foam Pro Stepper Control Board
Happy Days:
Yeah, not bad work Bill, well done. :clap:
Re soldering i.c.’s. I’d advise you not to reduce the heat as this could create a dry joint. The “skill” to good soldering is a good amount of heat on the iron and to quickly solder the component to the board. If you take too long either the component could get damaged, or the “track” could come away from the board.
If you’re dubious about damaging the component, Maplin used to sell a little tool called a soldering heat sink. Made of alloy it clips onto the components wire, (on the component side of the board) to stop too much heat getting to the component.
If you haven’t got one, try using a very small pair of thin nose pliers with an elastic band around the handle to keep the pliers gripping the wire of the component you are soldering.
I repeat; good soldering to a p.c.b is done quickly, with a hot iron.
Good Luck
Keith

Thanks Keith.

Eventually got the bottle up to check my work. :shock:
Ran the 12V test that HobbyCNC recommend before fitting the chips.
Needs a areading of 5 - 5.2v across a specified area. I got 5.02v and no BANGS :D
Can now move on and fit the chips. :) :)
Happy Days:
Very good Bill, voltage is nicely within spec. I predict this pcb will run perfectly, and won’t you feel good when it does!
(Just check that you’ve got the chips in the right way round Before you solder them,………depending on how they’re marked it can be easy to put them in the wrong way round………ask me how I know :oops: :oops: )
