These PCBs (and I suppose more specifically whatever parts are on them) seem to be made of literal garbage — and yet they cost a mint. Had a wall oven with an “error code” - diagnosis: replace board, part cost $400, internet says there has been no revision of the board so the new board will likely fail the same way, and only the part would be warranted so the other $500 in labor cost to fix it could be incurred again next month or next year. Ended up throwing away the whole double oven.

Meanwhile I know a PCB and a few boring ICs and resistors actually cost like $30 max so I know that we are being scammed.
