Nrog rau kev loj hlob ntawm kev lag luam hauv Circuit Court, thiab kev nce qib thiab nrov ntawm daim ntawv thov teb, ntau thiab ntau Sanxin IC chips tshwm sim hauv khw.
Tam sim no, muaj ntau yam khoom cuav thiab shoddy circulating nyob rau hauv kev ua lag luam ntawm cov khoom siv hluav taws xob thiab cov khoom siv. Tshwj xeeb, tau tsav los ntawm kev txaus siab, muaj ob peb tus neeg uas siv cov khoom tsis zoo thiab cov khoom cuav hauv kev ua lag luam, uas ua rau muaj kev puas tsuaj rau kev lag luam ib puag ncig, tsis tsuas yog cuam tshuam cov cuab yeej cuab tam ntawm cov tuam txhab qub, tab sis kuj ua rau muaj kev phom sij rau cov khoom siv hluav taws xob zoo, thiab cuam tshuam rau kev txaus siab ntawm txhua qhov kev sib txuas hauv cov saw hlau ntawm Tuam Tshoj txoj kev lag luam hluav taws xob. Nws tau coj phem cuam tshuam rau kev noj qab haus huv txoj kev loj hlob ntawm kev lag luam.
Muaj ntau yam IC chips nyob rau hauv kev ua lag luam, thiab qee zaum nws nyuaj rau kev paub qhov txawv ntawm ntau yam ntaub ntawv, yog li kev txheeb xyuas ntawm IC cuav kev kho dua tshiab yog qhov tseem ceeb heev.
Nov yog qee yam hom retread
01 disassembly
Cov khoom siv raug tshem tawm los ntawm cov khoom siv rov ua dua tshiab PCB tom qab ntawd rov kho dua los ntawm kev sib tsoo, txheej, rov ua dua, rov tinning, xov thiab lwm yam txheej txheem;
Nta: Cov qauv tsis hloov pauv, qhov saum npoo ntawm cov khoom lub cev tau polished thiab rov coated, feem ntau tus pin yuav rov tinned lossis rov cog pob (nyob ntawm qhov ntim);
02 Cov khoom cuav
Ib hom khoom siv, tom qab kev sib tsoo thiab txheej txheej kho dua tshiab, ntaus B hom khoom, hom khoom cuav no yog qhov txaus ntshai heev, qee qhov haujlwm tsis raug, siv tsis tau, tsuas yog ntim khoom;
03 khoom
Lub sijhawm cov khoom lag luam ntev heev, cov qauv qub, tus nqi tsis zoo, kev ua lag luam tsis zoo, thiab tom qab ntawd polishing, txheej, rov ua dua, ntaus lub Xyoo Tshiab
04 Re-tinned
Rau qee cov ntaub ntawv qub lossis cov ntaub ntawv khaws cia tsis zoo, cov pins yuav raug oxidized, uas yuav cuam tshuam rau kev thauj khoom. Tom qab kev kho mob, rov tinning lossis rov cog dua, cov pins yuav zoo nkauj dua thiab yooj yim rau kev thauj khoom.
05 Cov khoom tsis raug ntawm lub Hoobkas thawj
Tom qab thawj lub Hoobkas tau sim, ib feem ntawm cov khoom uas tsis sib xws yuav raug tshem tawm. Qee cov ntaub ntawv hauv ntu no yuav raug muab pov tseg los ntawm lub Hoobkas qub, thaum qee qhov yuav ntws mus rau hauv kev lag luam los ntawm cov kev tshwj xeeb. Vim tias muaj ntau ntau thiab lwm yam khoom siv, ib tus neeg yuav rov qab polish, lub tsho tiv no, khij ib pawg sib koom ua ke, thiab rov ntim dua, txhawm rau txhim kho kev muag khoom!
06 Thawj mantissa los yog ntau pawg ntawm cov qauv
Vim tias cov batch muaj ntau thiab ntau yam, qee qhov chaw tsim khoom qub yuav rov qab polish txheej, ua kom muaj kev sib koom ua ke, ua tiav ntim, ntim thiab xa khoom;
07 Rov kho cov qauv duab
