Crystal oscillator: citizen, MURATA
2. procurement strategy
Standard components, such as IC, are selected only by agents posted by official website.
Firmly reject market spot, such as SEG's spot.
Standard components are small batch or urgent delivery: DigiKey, element, RS, Mouser
Non standard components, such as PCB, are selected from the top 10 suppliers in Shenzhen, such as Chong DA and Zhi en.
8 goods to ensure that the material price is reasonable.
Under customer approval and quality assurance, substitute materials are selected.
3. component inspection
Sample stage: product engineers strictly test samples according to the specification when new materials are imported.
Bulk purchase stage: IQC according to MIL-STD-105E sampling plan II level standard.
Eight, test ability: 8 AOI, 1 ICT
