Fab equipment spares, handling parts and metrology artefacts move here on exactly the same logic as in Hsinchu: the tool is down, the part is small, and the hourly cost is not in dispute. Optoelectronics adds a related stream.
Tainan is further from Taoyuan than Hsinchu is, so the surface leg is a real part of the plan. Kaohsiung is closer and occasionally the better arrival where the international schedule supports it.
