Moving Caps-n-Coils - Electrical Complications?
Posted by: Trash80toHP_Mini on 2013-04-24 10:22:08
Is there any electrical reason this Tank Farm and Coil couldn't be relocated an inch or two to the right?

I'm thinking caps with heat shrunk wire leads and a wired extension for the coil with everything hot glued to a carrier board ought to be OK.

What say? :?:

The thing you will want to watch for is parasitic inductance and resistance in the leads. That looks like a switchmode regulator which can have very high peak currents at high frequencies. Notice the parts are clustered tightly together connected by big fat traces. You can *probably* get away with moving things around a bit, but make sure you use heavy enough wires and keep them as short and direct as possible.

Are you trying to make room for a longer hard drive? You might see if you can find tantalum or ceramic capacitors that are low profile enough to fit under it without moving them.

THX, yep, I figured that tank farm and coil are the ElectroCrud for conditioning/converting the battery's power input, I'll either not be using a removable battery at all or using a different form factor battery mounted 90 degrees counterclockwise from that connector. That depends only upon electrical compatibility of the replacement battery and the successful lopping off of about 1/2" to 3/4" of the, all but empty, PCB peninsula where the FDD connector is right smack dab in the way.

HDD was a good guess! :approve: Make that a CD-ROM drive poking out the left side and you'd be right on the money! [}🙂] ]'>

Where is Waldo? The 1400 boots and runs TechToolPro from the CD just fine, but some parts are conspicuously out of place. }🙂
