PCB kukopera kumatchedwanso kukopera kwa PCB, kupanga kwa PCB, kukopera kwa PCB, kupanga ma PCB, mapangidwe a PCB kapena kapangidwe ka PCB. That is, on the premise of having physical electronic products and circuit boards, reverse analysis of circuit boards is carried out by means of reverse research and development technology, and technical documents such as PCB files, BOM files, schematic diagram files and PCB silkscreen production files of original products are carried out 1: 1, kenako gwiritsani ntchito zikalata zaukadaulo ndi zolemba zanu pakupanga ma board a PCB, kuwotcherera gawo, kuyesa mayeso a singano, kukonza kwa board of board, malizitsani mtundu woyambirira wa board board.

Pogwiritsa ntchito bolodi yokopera ya PCB, anthu ambiri samvetsa, kodi bolodi yokopera ya PCB ndi chiyani, anthu ena amaganiza kuti PCB yokopera ndi copycat. M’kumvetsetsa kwa aliyense, shanzhai amatanthauza kutsanzira, koma kukopera kwa PCB sikutsanzira. Cholinga cha kukopera kwa PCB ndikuphunzira ukadaulo wapakompyuta wakunja wakunja, kenako ndikutengera njira zabwino kwambiri, ndikuzigwiritsa ntchito kupanga ndikupanga zinthu zabwino.

With the continuous development and deepening of the board copying industry, today’s PCB board copying concept has been extended in a wider range, no longer limited to simple circuit board copying and cloning, but also involves the secondary development of products and the research and development of new products. Mwachitsanzo, pofufuza zolemba zaukadaulo, kapangidwe kalingaliro, kapangidwe kake ndi ukadaulo wakumvetsetsa ndi kukambirana, zitha kupereka kuwunika kotheka pakufufuza ndi kupanga zatsopano ndi zambiri zampikisano, kuti zithandizire pakufufuza ndi kapangidwe kazinthu kutsatira kwakanthawi kwakanthawi kachitukuko chaukadaulo, kusintha kwakanthawi kwakanthawi kuti musinthe kapangidwe kazogulitsa, kafukufuku ndi chitukuko ambiri ali ndi msika wazipikisano zatsopano.

Njira yakukopera ma board a PCB imatha kuzindikira kusinthika mwachangu, kukulitsa ndi chitukuko chachiwiri cha mitundu ingapo yazinthu zamagetsi kudzera m’zigawo ndikusintha pang’ono kwamafayilo aukadaulo. Malinga ndi kujambula kwa chikalatacho ndi zojambulidwa zojambulidwa kuchokera ku kukopera kwa PCB, opanga akatswiri amathanso kukonzanso kapangidwe ndikusintha PCB malinga ndi zomwe kasitomala akufuna. Pachifukwa ichi, imathanso kuwonjezera ntchito zatsopano kapena kukonzanso magwiridwe antchito, kuti malonda omwe ali ndi ntchito zatsopano awonekere mwachangu kwambiri komanso posachedwa, sikuti ali ndi ufulu wawo wanzeru zokha, komanso amapambana mwayi woyamba pamsika, kubweretsa zabwino ziwiri kwa makasitomala.

Kaya imagwiritsidwa ntchito pofufuza mfundo zama board ndi zinthu zomwe zimagwiritsidwa ntchito popanga kafukufuku wosinthika, kapena ngati maziko a kapangidwe ka PCB pakupanga kwamtsogolo, PCB yoyeserera ili ndi gawo lapadera. Chifukwa chake, malinga ndi chikalatacho kapena chinthu, momwe mungachitire chithunzi chojambula cha PCB cham’mbuyo, njira yobwerera m’mbuyo ndiyotani? Kodi ndi mfundo ziti zofunika kuzimvera?

Masitepe obwerera m’mbuyo:

1. Record PCB details

Pezani PCB, choyamba papepala kuti mulembe zonse zopangira mtundu, magawo, ndi malo, makamaka diode, malangizo a chubu cha magawo atatu, malangizo a IC notch. It is best to take two pictures of the location of the components with a digital camera. Mabungwe ambiri a PCB amatsogola kwambiri kuposa diode triode ena samvera kuti angowona.

2. Scanned images

Chotsani zinthu zonse ndikuchotsa malata m’mabowo a PAD. Sambani PCB ndi mowa ndikuyiyika mu sikani yomwe imayang’ana mapikiselo apamwamba pang’ono kuti mupeze chithunzi cholimba. Kenako, pukutani kumtunda ndi pansi mopepuka ndi pepala loluka madzi mpaka filimu yamkuwa iwala. Ikani mu sikani, yambani PHOTOSHOP, ndikusakaniza magawo awiriwo mosiyanasiyana. Note that PCB must be placed horizontally and vertically in the scanner, otherwise the scanned image can not be used.

3. Adjust and correct the image

Sinthani kusiyanasiyana komanso kupepuka kwa chinsalucho, kuti gawoli ndi kanema wamkuwa komanso gawo lopanda kusiyanasiyana mwamphamvu, kenako mutembenuzire gawo lakuda ndi loyera, muwone ngati mizereyo ili yoyera, ngati sichoncho, bwerezani izi. Ngati zikuwonekeratu, chithunzicho chimasungidwa ngati ma fayilo akuda ndi oyera a BMP TOP BMP ndi BOT BMP, ngati chithunzichi chikupezeka kuti chili ndi mavuto akhozanso kukonzedwa ndikukonzedwa ndi PHOTOSHOP.

4. Verify PAD and VIA position coincidence

Sinthani mafayilo awiri a BMP kukhala mafayilo a PROTEL motsatana, ndikusamutsa magawo awiri kukhala PROTEL. Mwachitsanzo, maudindo a PAD ndi VIA pambuyo pa zigawo ziwiri zimagwirizana, kuwonetsa kuti mayendedwe am’mbuyomu adachitika bwino. Ngati pali kupatuka kulikonse, bwerezani sitepe yachitatu. Chifukwa chake, kukopera ma board a PCB ndi ntchito yoleza mtima kwambiri, chifukwa vuto laling’ono limakhudza mtunduwo komanso digiri yofananira mukakopera.

5. Draw the layer

Convert TOP layer BMP to TOP PCB, make sure to convert SILK layer, the yellow layer, then you trace the line on TOP layer, and place the device according to the drawing in step 2. Chotsani SILK wosanjikiza mutatha kujambula. Repeat until you have drawn all the layers.

6. Kuphatikiza kwa TOP PCB ndi BOT PCB

Add TOP PCB and BOT PCB in PROTEL and combine them into one figure.

7. Laser kusindikiza TOP LAYER, BOTTOM LAYER

Gwiritsani ntchito chosindikizira cha laser kusindikiza TOP LAYER ndi BOTTOM LAYER mufilimu yowonekera (1: 1 ratio), ikani kanemayo pa PCB ija ndikuyerekeza ngati ili yolakwika, ngati ili yolondola, mwatha.

Yesani 8.

Yesani magwiridwe antchito amama board of copy sikofanana ndi bolodi loyambirira. If it’s the same then it’s really done.

Chachiwiri, samalani zambiri

1. Gawani moyenera magwiridwe antchito

When reverse designing the schematic diagram of an intact PCB, reasonable division of functional areas can help engineers reduce some unnecessary trouble and improve the efficiency of drawing. Generally speaking, components with the same function on a PCB board will be arranged centrally, so that the functional division of areas can provide a convenient and accurate basis for reverting the schematic diagram.

Komabe, kugawidwa kwa malo ogwira ntchitowa sikungosinthasintha. Zimafunikira akatswiri kuti amvetsetse zina zamagetsi zamagetsi zamagetsi. Choyambirira, fufuzani zigawo zikuluzikulu zamagulu ogwirira ntchito, kenako molumikizana ndi kulumikizana kwa waya kuti mufufuze zigawo zina za chinthu chomwecho, mapangidwe a magawano ogwira ntchito. Mapangidwe magawidwe ogwira ntchito ndiye maziko azithunzi zojambula. Kuphatikiza apo, musaiwale kugwiritsa ntchito nambala yamagawo pa board board kukuthandizani kugawa ntchito mwachangu.

2. Pezani chidutswa choyambira

Chidutswa chofotokozedwachi chitha kunenedwa kuti ndi gawo lalikulu la mzinda wa PCB kumayambiliro ojambula. Mukazindikira zidutswazo, kujambula molingana ndi zikhomo za zolembedwazo zitha kutsimikizira kulondola kwa zojambulazo mozama kwambiri.

Benchmark ya mainjiniya, zowona sizinthu zovuta kwambiri, ambiri, amatha kusankha kutsogolera magawo azigawo ngati chikhomo, nthawi zambiri amakhala akulu, amapinikiza kwambiri, kujambula kosavuta, monga dera losakanikirana, thiransifoma, transistor, ndi zina zambiri. ., ali oyenera ngati chizindikiro.

3. Siyanitsani bwino mizere ndikujambula zingwe zomveka

Kuti musiyanitse waya wapansi, mzere wamagetsi ndi mzere wazizindikiro, akatswiri amafunikiranso kukhala ndi chidziwitso chofunikira chamagetsi, kulumikiza kwa dera, kulumikizana kwa PCB ndi zina zambiri. Kusiyanitsa kwa madera awa kumatha kufufuzidwa kuchokera kulumikizidwe kwa zinthu, kukula kwa zojambulazo zamkuwa ndi mawonekedwe azinthu zamagetsi zokha.

Pakujambula kwa waya, kuti mupewe kuwoloka mzere ndikulowererapo, nthaka ingagwiritse ntchito zizindikilo zingapo, mizere yonse ingagwiritse ntchito mitundu yosiyanasiyana ya mizere yosiyanasiyana kuti iwonetsedwe bwino, chifukwa mitundu yonse yazinthu itha kugwiritsanso ntchito zina zapadera zizindikiro, ndipo amatha kulekanitsa zojambulazo, kenako ndikuphatikiza.

4. Master the basic framework and refer to similar schematic diagrams

Pazinthu zina zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsi zamagetsiKwa njira zina zoyambirira zamagetsi zamagetsi zamagetsi ndi njira yojambulira, mainjiniya amafunika kudziwa, osati kungodziwa zojambula zoyambira za dera, komanso kuti apange mawonekedwe amagetsi.

Kumbali inayi, osanyalanyaza kuti mtundu womwewo wazinthu zamagetsi uli ndi kufanana kwina pachithunzi chazithunzi zanyumba ya PCB, mainjiniya atha kutengera kuchuluka kwa zomwe akumana nazo, kujambula chithunzi chofananira chimodzimodzi kuti akwaniritse zatsopano chithunzi chojambula.

5. Onetsetsani ndikukwaniritsa

Chithunzi chojambulacho chikamalizidwa, kapangidwe kazithunzi kazithunzi ka PCB kakhoza kumaliza pokhapokha mutayesedwa ndikuyang’ana. The nominal values of components sensitive to PCB distribution parameters need to be checked and optimized. According to the PCB file diagram, the schematic diagram is compared, analyzed and checked to ensure that the schematic diagram is completely consistent with the file diagram.
