Front end · I010–I035
cleanroom ISO 7 — solder paste printed on DBC, SiC modules placed, sintered, X-rayed
Sinter press · I030
silver sinter under pressure & temperature — the pacemaker of the whole line
I030 —BOTTLENECK
Sinter / Reflow
SiC dies silver-sintered to the DBC at 130 s per cycle — the slowest station on the line; everything upstream queues here, everything downstream is paced by it.
sintered power stages flow into module assembly
Module assembly · I040–I050
ESD zone — wire bonds & busbars, gate driver, housing & potting
potted inverters go to leak test and HV end-of-line
Test · I055–I060
coolant circuit integrity, then the HV end-of-line rig signs the unit off
Unit of production = the inverter (serials INV-). Line served by AGV-B (solder paste, SiC modules, busbar kits, gate drivers, potting resin — small kanban bins, ~10–15 min cycles).
