indlela yokwenza pcb wesifunda

I-PCB (Printed Circuit Board) iyisisekelo sezinto zikagesi, ezivumela ukuxhumana nokugeleza kukagesi phakathi kwezingxenye ezihlukahlukene.Noma ngabe ungumuntu othanda izinto zikagesi noma uchwepheshe, ukwazi ukuthi udala kanjani amasekhethi e-PCB kuyikhono elibalulekile elingathuthukisa amaphrojekthi akho obuchwepheshe.Kule bhulogi, sizohlinzeka ngomhlahlandlela wesinyathelo ngesinyathelo sendlela yokwenza isekethe ye-PCB.

1. Idizayini nokudalwa kohlelo:

Isinyathelo sokuqala ekwenzeni isekethe ye-PCB ukudizayina nokudala uhlelo.Usebenzisa isofthiwe yokuklama isikimu, njenge-Eagle noma i-KiCad, dweba umdwebo wesifunda.Ukubekwa ngokucophelela kwezingxenye, ukwakheka okuphelele okuqinisekisa ukuhamba okunengqondo kwamasignali kanye nomzila ophumelelayo kubalulekile.

2. Isakhiwo se-PCB:

Uma isikimu sesiphelile, isinyathelo esilandelayo ukwakha isakhiwo se-PCB.Le nqubo ibandakanya ukudlulisa izingxenye nokuxhumana kusuka kuhlelo kuya ekwakhiweni kwebhodi elibonakalayo.Qondanisa izingxenye namaphakheji azo, uqinisekise ukuma okulungile nokugcina isikhala esifanele ukugwema ukuphazamiseka.

3. Ukufakwa kwamapuleti:

Uma isakhiwo se-PCB sesiqediwe, sekuyisikhathi sokuqopha ibhodi.Okokuqala phrinta umklamo webhodi lesifunda ephepheni elikhethekile lokudlulisa usebenzisa iphrinta ye-laser.Beka okuphrintiwe ku-PCB egqoke ithusi bese uyishisa ngensimbi noma nge-laminator.Ukushisa kudlulisa uyinki kusuka ephepheni kuya ebhodini, kwakha ungqimba oluvikelayo emithonjeni yethusi.

4. Inqubo yokunamathisela:

Uma ukudlulisa sekuqediwe, sekuyisikhathi sokuqopha ibhodi.Lungiselela isitsha esinesixazululo esifanelekile sokuhlanganisa (njenge-ferric chloride) bese ucwilisa ibhodi kuso.Gcoba ngobumnene isisombululo ukuze ususe ithusi eliningi ezindaweni ezingavikelekile, ushiye kuphela iminonjana oyifunayo.Phakathi nale nqubo, qiniseka ukuthi uthatha izinyathelo zokuphepha ezifana nokugqoka amagilavu ​​nezibuko, njengoba isixazululo se-etching singaba yingozi.

5. Ukumba:

Ngemuva kokucwiliswa, izimbobo zidinga ukubhobozwa ukuze kubekwe izingxenye.Sebenzisa i-drill enencanyana encane efana nosayizi wengxenye yokuhola.Gcoba ngokucophelela ezindaweni ezikhethiwe bese uqinisekisa ukuthi izimbobo zihlanzekile futhi azinayo imfucumfucu.

6. Ukushisela:

Ngemuva kokuthi ibhodi liqoshwe futhi kwabholwa izimbobo, sekuyisikhathi sokuthengisa izingxenye ku-PCB.Qala ngokuxhuma izingxenye emigodini yazo, uqiniseke ukuthi zihlezi ngokuphephile.Phenya ibhodi futhi uthengise ingxenye ngayinye, usebenzise ukushisa ukuze uncibilikise intambo ye-solder futhi wenze isibopho esiqinile.Sebenzisa insimbi ye-soldering yekhwalithi kanye ne-flux ukuze uzuze amalunga ahlanzekile, athembekile.

7. Isivivinyo:

Ngemuva kokuhlanganisa zonke izingxenye, ukusebenza kwesifunda kufanele kuhlolwe.Sebenzisa i-multimeter ukuze uhlole ukuqhubeka kokulandelela futhi uqinisekise ukuxhumana okufanele.Futhi, yenza ukuhlolwa okubonakalayo ukuze uqiniseke ukuthi awekho amabhuloho e-solder noma amalunga abandayo.

Ekuphetheni:

Ukudala amasekhethi e-PCB kungase kubonakale kunzima ekuqaleni, kodwa ngolwazi olufanele namathuluzi, kungaba umsebenzi ofinyelelekayo.Ngokulandela umhlahlandlela wesinyathelo ngesinyathelo onikezwe kule bhulogi, ungenza ngokuzethemba amasekhethi e-PCB kumaphrojekthi akho kagesi.Khumbula, ukuzijwayeza kwenza kuphelele, ngakho-ke ungadikibali uma kuthatha imizamo embalwa ukuze uthole i-hang yenqubo.Ngokuhamba kwesikhathi nolwazi, uzokwazi ukudala ngempumelelo amasekhethi e-PCB ayinkimbinkimbi futhi asebenza kahle kakhulu.
