I-Circuit Board Reverse Engineering Services

Ibhodi eligcina umugqa wokukhiqiza usebenza lihlulekile. Umkhiqizi wokuqala uvale ngo-2011. Amafayela okuklama awazange adluliselwe. Okuwukuphela kwendlela eya phambili - ngaphandle kokushintsha lonke uhlelo ngezindleko zezinombolo eziyisithupha - ukuphinda ibhodi lisuka kuyunithi ebonakalayo esekhona.

Yileso simo izinhlangano eziningi ezikuso lapho zifuna izinsizakalo zobunjiniyela obuphambene nebhodi lesifunda . Akuyona ilukuluku lezemfundo. Inkinga ethile, enesikhathi sangempela sokungasebenzi kanye nezindleko zangempela ezihambisana nayo.

Lo mhlahlandlela uhlanganisa lokho okulethwa ukuzibandakanya kobuchwepheshe be-PCB reverse engineering , okwenza amaphrojekthi abe nzima kunalokho abukeka ngakho, lokho okungenakubuyiselwa, ukuthi kubiza malini, nokuthi ungakhetha kanjani umhlinzeki ongeke akushiye usesimweni esibi kakhulu kunangesikhathi uqala.

1. Kungani Amabhodi Ephela Engenawo Amadokhumenti

Ukuqonda ukuthi kungani amadokhumenti enyamalala kusiza ukusetha amathemba angokoqobo ngalokho ubunjiniyela obuphambene obungakwenza nokungenakukwakha kabusha.

Izizathu ezivame kakhulu zokuthi kungani amafayela okuklama engasekho:

• Ukuvalwa komkhiqizi wokuqala: Umenzi wenkontileka noma indlu yokuklama eyakha ibhodi yavala, yathengwa, noma yayeka umugqa womkhiqizo. Amafayela awadluliselwanga — noma adluliselwanga ngokuphelele.
• Ukulahleka kwedatha ngesikhathi sokushintsha kwebhizinisi: Ukuthengwa, ukuhlanganiswa, kanye nokususwa kwezikhungo kuyimbangela evame kakhulu yokulahleka kwedatha yokuklama emikhakheni yezimboni kanye nemishini yezokwelapha. Ibhodi eyaklanywa ngo-1995 kungenzeka ukuthi yashintsha izandla kathathu ngaphambi kokuba noma ubani aqaphele ukuthi amafayela aphelile.
• Ukugodla ngamabomu: Abanye abakhiqizi bokuqala bagcina amafayela okuklama njengethuluzi lokuhweba — okuwukuphela kwendlela yokuthola amabhodi okufaka esikhundleni sawo ukuwathenga ku-OEM. Ubunjiniyela bokubuyela emuva bebhodi lesekethe buqeda lokho kuncika.
• Akukaze kubhalwe phansi kwasekuqaleni: Ukushintsha kwesibonelo kuya ekukhiqizeni ezinkampanini ezincane kuvame ukweqa amadokhumenti asemthethweni. Unjiniyela owaklama ibhodi akasekho, futhi okusele yiyunithi esebenzayo hhayi okunye.
• Ukufometha okuphelelwe yisikhathi: Amafayela akhona kodwa asezinguqulweni zesofthiwe noma amafomethi angasafundeki yinoma yiliphi ithuluzi lamanje — alahlekile ngokusebenza ngisho noma ekhona ngokoqobo.

Kuzo zonke lezi zimo, ibhodi elibonakalayo lingumthombo oyinhloko weqiniso. Konke okuveliswa yinqubo yobunjiniyela obuphambene kwakhiwa kabusha kusukela kulowo bufakazi obubonakalayo.

2. Lokho Okukhiqizwa Yisevisi Ngempela

Ukuzibandakanya kobunjiniyela obuphambene nebhodi lesifunda kukhiqiza iphakheji ephelele yamadokhumenti — isethi efanayo yamafayela abengaba khona ukube ibhodi yaklanywa kusukela ekuqaleni ngaphakathi endlini. Imiphumela eyinhloko:

Indlela i-schematic eyakhiwa ngayo kabusha yingxenye amaklayenti amaningi angayiboni kodwa ayikhathalela kakhulu. Onjiniyela abagcini nje ngokulandelela ithusi - bahlaziya i-topology yesekethe: bakhomba ukwakheka kokunikezwa kwamandla, bamepha iprosesa I/O, balandelele uchungechunge lwesignali ye-analog, futhi babhale phansi ukuthi isigaba ngasinye senza ini ngokusebenza. Ukukhishwa kwe-schematic okubonisa kuphela ukuxhumana ngaphandle kokuqonda okusebenzayo kukhiqiza idokhumenti ephelele ngobuchwepheshe kodwa cishe engasizi ngalutho ekuxazululeni izinkinga noma ekuguqulweni.

Kusho ukuthini ukuqinisekiswa kwephrothokholi kuwe: Iphakheji yamadokhumenti iqinisekiswa kuphela ukuthi ilungile uma ibhodi lenziwe ngamafayela e-Gerber futhi lahlanganiswa kusuka ku-BOM lisebenza futhi lisebenza ngendlela efanayo neyokuqala. Noma yikuphi ukungafani — umkhondo ophuthelwe, inani lengxenye elingalungile, isabelo esingalungile — kuvela lapha, ngaphambi kokuthi uthole amafayela. Ngaphandle kokuqinisekiswa kwephrothokholi, uthola ukwakhiwa kabusha okungaqinisekisiwe.

Izinto ongazikhethela ezitholakala kubahlinzeki bezinsizakalo ezigcwele:

• I-Firmware binary (lapho ingakwazi ukukhishwa khona ngokomthetho nangokomthetho — bheka iSigaba 4)
• Izincomo zokushintsha izingxenye eziphelelwe yisikhathi ezinezilinganiso zesimanje
• Imodeli ye-STEP 3D yokuqinisekiswa kokuhlanganiswa kwemishini
• Amabhodi okufaka esikhundleni akhiwe futhi ahlolwe njengengxenye yokuzibandakanya

3. Izinguquko Ezinzima: Okubangela Ukuthi Iphrojekthi Ihambe Kancane

Yonke iphrojekthi yobunjiniyela bebhodi lesifunda ibukeka ilula kuze kube yilapho ingabonakali. Lezi yizinto ezishintshashintshayo ezandisa isikhathi futhi zandise izindleko - okufanele uzazi ngaphambi kokuthi uthumele ibhodi ukuze lihlaziywe.

Ukubalwa kwezingqimba yikona okubangela izindleko kanye nesikhathi. Izingqimba zangaphandle zithathwa ngeso lengqondo. Izingqimba zangaphakathi ebhodini lezingqimba ezingu-4+ zidinga ukuthwebula izithombe ze-X-ray noma ukuskena kwe-CT. Ibhodi elinezingqimba ezingu-8 aliwona umsebenzi webhodi elinezingqimba ezingu-4x — lingu-6–8x ngenxa yokuxhumana kwezingqimba okumelwe kulandelwe futhi kuqinisekiswe kuyo yonke inhlanganisela yezingqimba. Kumabhodi e-HDI anama-microvia nama-vias angaboni/afihliwe, ukuskena kwe-CT kuyadingeka ngoba i-X-ray ayikwazi ukuxazulula ukuqoqwa ngezakhiwo.

Izingxenye ezingamakiwe noma ezenziwe ngokwezifiso ziyizinto ezingalindelekile kakhulu. Ukumakwa kwe-IC okuhlanjululwe ngesihlabathi noma i-ASIC eyenziwe ngokwezifiso engenawo amadokhumenti omphakathi kungadinga izinsuku zokuhlaziywa kokusebenza — ukulandelela amajika, ukuhlolwa kokuziphatha, futhi ngezinye izikhathi ukuhlukaniswa kwama-capsulation — ukuthola ukuthi iyini ingxenye nokuthi yenzani. I-IC eyodwa eyenziwe ngokwezifiso engaziwa ingangeza amasonto angu-1-2 kuphrojekthi.

Umonakalo webhodi uphoqa ukuqagela esikhundleni sokubuka. Umzila oshile, ingxenye ebolile, noma izingxenye ezingekho zidinga onjiniyela ukuthi bakhe kabusha lokho okwakukhona kusukela kumongo wesekethe ezungezile. Lokhu ukwahlulela kobunjiniyela, hhayi ukulinganisa - kunezela ukungaqiniseki futhi kudinga ukuqinisekiswa kokusebenza ukuqinisekisa ukuthi ukuqagela bekulungile.

Izici zesimo sebhodi ezandisa ububanzi bephrojekthi:

• Isembozo esihlanganisiwe noma esimboziwe esimboza izimpawu noma iminonjana yezingxenye
• Lungisa izintambo noma usike ama-trace abonisa ukuguqulwa kwensimu (yiyiphi inguqulo elungile?)
• Imizamo yokulungisa yangaphambilini eshintshe isekethe yokuqala
• Ukugqwala okubangelwa umswakama noma ukuchayeka ngamakhemikhali okufihla ukuxhumeka kwamaphedi
• Ibhodi elilodwa kuphela lesampula elitholakalayo — uma kudingeka ukuhlaziywa kwezingqimba ezibhubhisayo, ulahlekelwa yiyunithi yokubhekisela kuphela

Ukuhlinzeka okungenani amabhodi amabili esampula — elilodwa lokuhlaziya okungonakalisi kanye nelinye elingasetshenziswa ekuhlukaniseni izingxenye ezibhubhisayo uma kudingeka — kunciphisa kakhulu ingozi yephrojekthi kanye nesikhathi.

4. I-Firmware, ama-ASIC, kanye nalokho okungenakutholakala

Lesi yisigaba iningi lezinsizakalo zobunjiniyela bebhodi lesifunda elidlulayo eliyeqayo. Sibaluleke kakhulu kunanoma iyiphi enye ingxenye yokuhlola.

I-firmware ye-Microcontroller ayiyona ingxenye ye-PCB — iyisofthiwe efakwe kudivayisi. Inqubo yobunjiniyela obuphambene iyakha kabusha umklamo wehadiwe kahle futhi ayisho lutho ngokuthi yiluphi uhlelo olusebenza ku-MCU. Uma i-MCU ingenalutho noma isusiwe, ibhodi eliphindiwe kabusha lizosebenza futhi lingenzi lutho. Ukukhishwa kwe-firmware kuyinqubo ehlukile edinga ukufunda ikhodi ehleliwe kusuka kudivayisi.

Ukuthi i-firmware ingakhishwa yini kuncike ngokuphelele ekuvikelweni kokufundwa kwe-MCU:

• Akukho sethi yokuvikela yokufunda: I-Firmware ingafundwa ngqo nomhleli wezinhlelo. Ivamile kumadizayini amadala kusukela ngawo-1990 kuya ku-2000.
• Ukuvikelwa kokufundwa kwesofthiwe (RDP): Ama-MCU amaningi esimanje (STM32, PIC, AVR, njll.) avumela unjiniyela ukuthi asethe i-read-protection bit. Uma esesethiwe, i-firmware ayikwazi ukukhishwa nganoma iyiphi indlela ejwayelekile ngaphandle kokubhubhisa idivayisi.
• Ukuphepha kwehadiwe: Izinto ezivikelekile kanye nama-MCU asebenzisa i-crypto anezindlela zokuzivikela ezibonakalayo ezenza ukukhipha kube nzima kakhulu noma kungenzeki ngaphandle kwemishini ekhethekile yelebhu ebiza amashumi ezinkulungwane zamaRandi ngomzamo ngamunye.

Uma i-MCU yebhodi lakho inikwe amandla okuvikela ukufunda — okuyinto eyenziwa amabhodi amaningi okukhiqiza — isevisi yobunjiniyela obuphambene ayikwazi ukukhipha i-firmware. Amadokhumenti ebhodi azoba aphelele futhi anembile, kodwa i-MCU kuzodingeka ihlelwe kabusha nge-firmware oyigcinayo noma oyivuselela kusukela ekuqaleni.

Ama-ASIC nama-FPGA enziwe ngokwezifiso aletha inkinga efanayo. Iphakheji ebonakalayo ingabonakala, i-pinout ingabonakala ngokuhlolwa kokusebenza, futhi isikhombimsebenzisi se-ASIC singabhalwa phansi. Kodwa i-logic yangaphakathi - lokho i-ASIC ekwenzayo ngempela - ibhokisi elimnyama. Ibhodi elikopishiwe eliqukethe i-ASIC efanayo lizosebenza kahle uma nje i-ASIC yokuqala itholakala. Uma i-ASIC ingasakhiqizwa futhi ingenakutholakala, ibhodi alikwazi ukuphinda likopishwe ngendlela yokusebenza kungakhathaliseki ukuthi imibhalo yobunjiniyela obuphambene iphelele kangakanani.

Impendulo eqotho ngaphambi kokusebenzisa noma iyiphi isevisi yobunjiniyela bebhodi lesifunda: Thola wonke amadivayisi angahlelwa ebhodini, nquma ukuthi ukukhishwa kwe-firmware kuyadingeka yini, bese ubuza umhlinzeki ngokuqondile ukuthi ikhono lawo kanye nezinga lempumelelo liyini emndenini wakho we-MCU. Umhlinzeki oqinisekisa ukukhishwa kwe-firmware kwama-MCU avikelwe ngokufunda ngaphandle kwezixwayiso akathembeki kuwe.

5. Izindleko kanye Nesikhathi: Lokho Izinombolo Ezithembele Kukho

Yini esunduza iphrojekthi kusukela ezindleko eziphakathi kuya kweziphezulu - futhi kungani:

Isendlalelo ngasinye sebhodi esengeziwe asiyona into eyengeziwe. Sidinga ukudlula kwesithombe okuhlukile, umsebenzi ophelele wokulandelela umkhondo walolo sendlalelo, kanye nokuqinisekiswa ngokumelene nazo zonke ezinye izendlalelo. Ibhodi elinezendlalelo ezingu-8 linezinhlanganisela ezingu-28 ezingaba khona zezendlalelo-mbili zokuhlola ukuxhumana — uma kuqhathaniswa ne-1 yebhodi elinezendlalelo ezimbili.

Ukwenziwa kwephrothokholi kanye nokuqinisekiswa kokusebenza, uma kufakiwe ekubandakanyekeni, kunezela u-$500–$3,000 kuye ngokuthi ibhodi liyinkimbinkimbi kangakanani — kodwa yindlela kuphela yokuqinisekisa ukuthi ukwakhiwa kabusha kulungile ngaphambi kokuba uthathe ubunikazi bamafayela.

Indlela yokuthola ikhotheshini enembile esicelweni sokuqala:

Thumela izithombe zezinhlangothi zombili zebhodi ngesisombululo esanele ukuze ufunde izimpawu zezingxenye, ubukhulu obuseduze bebhodi kanye nenani lezendlalelo ezibonakalayo kusukela emaphethelweni, noma yiluphi ulwazi olwaziwayo mayelana nomsebenzi webhodi noma umenzi wokuqala, izinto ezithile ozidingayo (amadokhumenti kuphela, noma amadokhumenti kanye namabhodi e-prototype), ukuthi ngabe ukukhishwa kwe-firmware kuyadingeka yini, nokuthi mangaki amabhodi esampula ongawanikeza. Ukuthunyelwa okungaphelele kukhiqiza izingcaphuno zobubanzi ezibanzi kakhulu ukuba zisebenze kuzo.

6. Indlela Yokugwema Ukuvalelwa Ngumhlinzeki Ongalungile

Lesi sigaba sikhona ngoba kukhona umkhuba othize embonini yobunjiniyela obuphambene nebhodi lesifunda obiza amaklayenti kakhulu kunesilinganiso sokuqala esiphakanyisiwe - futhi kufanelekile ukwazi ngaso ngaphambi kokuthi unikeze ibhodi lakho.

Ukukhiya amafayela: Abanye abahlinzeki baletha amafayela e-Gerber abonakala ephelele kodwa aqukethe amaphutha ngamabomu - iminonjana edluliselwe kumanethi angalungile, ama-via angekho, osayizi bephedi abangalungile - okwenza ibhodi lingalungiseki kunoma yimuphi omunye umenzi ngenkathi libonakala lilungile kumbukeli. Okuwukuphela kwendlela iklayenti elingathola ngayo amabhodi asebenzayo ukubuyela kumhlinzeki ukuze kwenziwe.
