A YouTube follower left this very insightful comment under our recent #RepairDontWaste podcast 👇 "I remember when working in industry equipment refurbish & repair. It was damn funny seeing some high tech hardware with low cost and unreliable eg. caps. I've nearly always replace those with actual high end capacitors (85->105 deg, lower esr, higher ripple, longer endurance). Same with transistors or power modules. Many happy clients and obviously really reliable equipment for many years to come. Sure there were some items where PCB was badly burnt and tracks in inner layers destroyed. It definitively require much more work but usually those were models no longer produced anyway. So client would have to replace whole damn system (and adapt software) instead of repairing one faulty obsolete unit. On the other hand... now I'm working in Automotive. And guess what, I open up such tesla inverter. It's 150-250kW unit. Liquid cooled. It doesn't need as big capacitor bank as industrial inverters connected to mains. It's actually very small. But then... what happens if power module is damaged? Oh... you can remove the PCB, no problem. Then you end up with laser welded copper plates connecting U, V, W, DC+, DC- to power modules. Custom made power modules which aren't available on the market. Power modules soldered to heatsink. Now assembly process is cost effective. Disassembly, repair, reassembly hardly is. At some point it will be, but because those units will no longer be produced and available. So their price will gradually go higher and higher to the point repair will actually be viable option. Or one might just buy another car which seems to be the goal of car manufacturers and their "anti repairability approach"." #Repairdontwaste #ukmfg #electronics #sustainability #circulareconomy #ewaste #pcb
