Core Circuit Production
Noise Source Module Fabrication
Rau cov qauv hluav taws xob digital, ib qho LFSR (Linear Feedback Shift Register) lossis FPGA-raws li pseudo-random sequence generation scheme yog nyiam, nrog cov cai programmed ntawm qis- zog co- processor ntawm lub ntsiab tswj nti (piv txwv li, QCC5171). Analog circuit qauv siv Zener/voltage-regulator diodes raws li lub suab nrov, tsim cov suab nrov hauv paus teeb liab los ntawm cov yam ntxwv rov qab.
Filtering thiab teeb liab ua
Lub suab nrov nrov dhau los ua spectral shaping; IIR / FIR cov ntxaij lim dej yog ua haujlwm los kho cov lus teb ntau zaus rau hom xws li cov suab paj nruag thiab suab nrov dawb, ua kom cov spectral uniformity nyob rau hauv 20Hz-20kHz ntau yog tswj nrog qhov yuam kev ntawm ± 1dB.
Unit Assembly
Cov khoom siv SMT thiab Soldering
Surface Mount Technology (SMT) yog siv los txhim kho cov khoom siv- xws li cov khoom siv hluav taws xob ua haujlwm, DAC chips, thiab cov khoom siv nco- mus rau PCB, tsim kev sib txuas rau lub hwj chim mov, suab tso zis, thiab kev tswj khawm. Rau cov tshuab kiv cua-raws li cov qauv, kev sib dhos ntawm chav kiv cua thiab cua ntws chamber tau ua ib txhij.
Tsev thiab Kev Ua Haujlwm Kev Ua Haujlwm Sib Koom Tes
Lub rooj tsav xwm hauv Circuit Court, hais lus, thiab cov khoom siv hluav taws xob tau muab tso rau hauv kev txhaj tshuaj -cov vaj tsev molded, kev sib xyaw ua haujlwm xws li timers, ntim tswj, thiab USB fais fab sib txuas. Cov qauv tsim los rau cov menyuam mos yuav tsum muaj EMI thaiv ntxiv los tiv thaiv kev cuam tshuam ntawm electromagnetic.
