Quality is NOT to be Negotiated!
RisunSemi is most concerned about the quality of the electronic components we sell.
In addition to strictly controlling supply channels and obtaining original shipment documents from suppliers, RisunSemi also needs to do as follow:
1 According to the testing standards, RisunSemi judges whether the packaging and printing of components are correct and whether the pins are tinned and oxidized. Visual inspection allows us to rule out counterfeit refurbishment, sanding and recoating.
2 X-ray testing is a real-time non-destructive analysis to check the internal conditions of components, mainly to check chip lead frame, wafer size, and gold wire bonding pattern. RisunSemi conducts X-ray sampling inspection on parts to ensure the packaging process.
3 The function test is to design a particular test circuit according to the datasheet, input the signal source to the sample, and analyze the signal’s logical relationship and the waveform’s changing state to detect the component’s functional characteristics.
