VFD broken pins repair

[MrPuhur]

I've got this VFD as a part of a linear scale digital readout, the vacuum seems fine but the pins on one side have been broken off. The VFD is a NEC FIP10B15, couldn't find a replacement one. The way I see it, I either have to somehow reconnect wires to it or replace it with a custom pcb with 7-segment LED displays.

Repair: Solder seems to stick to the tiny tips of the yellow traces still visible at the edge, though it falls off if even slightly touched. Because of this, I couldn't confirm if the solder had been conductively connected to the trace by measuring the resistance of the grid, which is the only ohmic contact between any 2 pins as far as I know. To connect the wires, I would probably have to get rid of a bit of glass to expose more of the traces, which seems rather absurd to try.

Replacing it with LEDs: The VFD has a convenient signal arrangement, so it seems to lend itself to replacement with common anode/cathode LED displays, possibly with nothing but resistors to be added. I might also need to modify the driver circuitry a bit.

What do you think? Is it worth to try to repair it or should I go straight to making that PCB?

With that deep of a gauge, the vacuum is barely holding on. If you keep heating it with soldering or messing with that edge, it will likely vent. Something like liquid metal/wire glue might work without disturbing the seal, but if that fails you'll probably have to replace it.

The problem you're going to have, even if you can get connectivity with conductive glue or whatever, is that end connection - the filament supply. That needs to carry much more current than the rest. I'd try that one first, if you can't get the filament working then there's no point in spending time on the others.
