PWB vs PCB Overview
Yakadhindwa Wiring Board
A rakadhindwa wiring board, kana PWB, ndiyo hwaro hwemagetsi mazhinji nhasi. PWB ibhodhi rakatsetseka risingabatise magetsi. Iine mitsetse yakakosha inonzi traces inotakura zviratidzo. Aya maronda anobatanidza mavara akasiyana pabhodhi. Kare kare mainjiniya aishandisa waya kubatanidza zvikamu. Izvi zvakaita kuti zvinhu zvikure uye zviome kugadzirisa. Wiring board yakadhindwa yakaita kuti zvinhu zvive nyore.
Mabhodhi e wiring akadhindwa akatanga mukutanga kwema1900. Muna 1903, Albert Hanson aive nepfungwa yekushandisa mitsetse yesimbi nemakomba. Muna 1925, Charles Ducas akaisa zvimiro zvedunhu pamapuranga chaiwo. Akabatsira kutanga pfungwa yematunhu akadhindwa. Paul Eisler akaita shanduko huru muna 1936. Akashandisa foil uye akaita maredhiyo nePWB yekutanga chaiyo. Munguva yeHondo Yenyika II, mauto eUS akashandisa mabhodhi aya mumabhomba. Izvi zvakaratidza kukosha kwavaiita.
Cherechedza: "Bhodhi remagetsi rakadhindwa" zvinoreva bhodhi rine mapatani emagetsi chete. Harina zvikamu pariri. Izvi zvakabatsira mainjiniya kuronga bhodhi vasati vawedzera chimwe chinhu.

Yakadhindwa Circuit Board
Bhodhi redunhu rakadhindwa, kana kuti PCB, rinotanga nePWB. Iyo PCB ine wiring pateni uye inewo zvikamu pairi. Zvikamu izvi zvinhu zvakaita seresistors, machipisi, uye zvinongedzo. Iyo PCB inobata zvikamu izvi uye inozvibatanidza. Izvi zvinogadzira dunhu rakazara rekushanda.
Vanhu vakatanga kuti “bhodhi redunhu rakadhindwa” mushure mekushanda kwaPaul Eisler muna 1936. Pakazosvika ma1940, mauto eUS akashandisa maPCB muzvombo. Muna 1948, hurumende yeUS yakati maPCB anogona kushandiswa mubhizinesi. Izvi zvakaita kuti nyika yemagetsi ikure nekukurumidza. MaPCB akachinja kubva kumabhodhi akareruka kuenda kune ane akawanda akaturikidzana. Mutsara wega wega une tunzira tudiki twemagetsi. Izvi zvinoita kuti michina iite diki uye yakasimba.
PCBs dzakachinja zvakanyanya nekufamba kwenguva:
Mumakore ekuma1960, makarukureta akashandisa maPCB ane anenge makumi matatu transistors. Ikozvino, makomputa ane mamirioni e transistors pane imwe chip.
Zvikamu senge capacitors uye resistors idiki zvakanyanya ikozvino.
Makomputa ekutanga ekumba kuma1970 akashandisa maPCB akaomarara.
Musika wePCB waikosha kudarika mabhiriyoni makumi masere neshanu emadhora muna 85. Inogona kunge iri madhora bhiriyoni zana ne2022. Chikamu chekutakura chip chakakura ne100% mugore rimwe chete.
Indasitiri yePCB yakakura nekukurumidza nekuda kwezvinhu zvitsva, kudhinda kwe 3D, uye kubatanidza kudiki. Shanduko idzi dzinobatsira kugadzira midziyo midiki uye yakasimba.
Magadzirirwo Akachinja Matemo
Mazwi ekuti PWB nePCB akachinja nekufamba kwenguva. Kare kare, "bhodhi rakadhindwa wiring board" raireva bhodhi rine waya chete. Paiwedzerwa zvikamu, rainzi “printed circuit board.” Sezvo tekinoroji yakava nani, vanhu vakamira kuita mutsauko mukuru pakati pezviviri izvi. Zvino, vanhu vazhinji vanoshandisa mazwi maviri kureva chinhu chimwe chete, kunze kwekunge vashanda mumabasa akakosha.
Kuchinja kubva pamabhodhi anewaya nemaoko kuenda kumatunhu akadhindwa kwaive basa guru. Midziyo yekare yaishandisa waya dzainonoka uye dzaidambuka nyore. Maseketi akadhindwa aiita kuti zvinhu zvikurumidze, zvisimbe, uye zvive nyore kugadzirisa. MaPCB ane zvidimbu zvesimbi uye zvisiri zvesimbi. Aya matinji anobata zvikamu uye anoabatanidza. Izvi zvinogadzira dunhu rakazara.
Muchidimbu, iyo pwb vs pcb hurukuro inoratidza kuti zvinhu zvachinja sei. Nyaya yemapuranga akadhindwa ewaya inoratidza mafambiro atakaita kubva pamapuranga ari nyore kuenda kune akaoma zvikuru. Nhasi, kunhonga PWB kana PCB zvinoenderana nekuti mangani enhengo aunoda uye zvaunoda kuti bhodhi riite.
Zvishandiso uye Chimiro
PWB Zvishandiso
Mainjiniya vanosarudza zvinhu zvepwb zvichienderana nezvinodiwa nedunhu. Vanofungawo nezvekuti bhodhi richashandiswa kupi. Substrate ndiyo chikamu chikuru chepwb yega yega. Mazhinji mapwb anoshandisa fiberglass-reinforced epoxy senge FR-4 sehwaro. Mamwe mabhodhi anoda polyimide kana ceramic substrates kuti adzore kupisa zviri nani. Mapatani ewaya anogadzirwa ne copper layer. Zvinoitwa nepwb zvinoshandura kuti inobata sei kupisa, inochengetedza magetsi mukati, uye inoramba yakasimba.
Kuenzanisa kwepwb laminate zvinhu zvinoratidza kuti sarudzo dzinokanganisa sei bhodhi rinoshanda. Tafura iri pazasi inoronga zvinhu zvakakosha:

Kuchengeta pwb ichitonhorera kwakakosha kuti ishande zvakanaka. Miedzo yakaita seUL746A uye IEEE STD 98 inobatsira kutarisa kuti pwb inotora nguva yakareba sei kana ichipisa. Kutora zvinhu zvakakodzera kunobatsira bhodhi kubata kupisa kwakanyanya uye kuramba ichishanda. Mainjiniya vanoedzawo kana bhodhi richikwanisa kumisa magetsi kubva pakudonha uye kana ikaramba yakasimba nekufamba kwenguva.
PCB Zvishandiso
A pcb inotanga ne pwb asi ine zvimwe zvikamu uye zvidimbu. Iyo pcb substrate inowanzoshandisa zvinhu zvakafanana se pwb, seFR-4. Vamwe yepamusoro pcbs vanoda inokosha laminates kana simbi-core substrates kubata mamwe kupisa. Iyo pcb inogadzirwa neiyo substrate, mhangura yemhangura, solder masks, silkscreen layer, uye dzimwe nguva yakawedzera yakavakirwa-mukati zvikamu.
Sezvo masekete anove madiki uye achiswedera pamwe chete, kuchengetedza pcb inotonhorera kunowedzera kuoma. Zvinhu zvakashandiswa zvinobatsira pcb kutamisa kupisa kure nezvikamu zvakabatikana. Vamwe yakakwirira-magumo pcbs kushandisa zvedongo kana aruminiyamu substrates kubatsira kupisa. Kugadzira pcb zvinoreva kuenzanisa zvinhu kuti zvibatane pamwe chete, zvinogona kuumbwa zvakanaka, uye zvikamu zvinogona kubatanidzwa zvakanaka.
Mainjiniya anotarisa kuti chinhu chimwe nechimwe chinobata sei kupisa, chinomisa magetsi kubva pakudonha, uye chinoramba chakasimba. The yakanakisisa musanganiswa zvinhu zvinobatsira pcb kugara kwenguva refu uye kushanda nematunhu akaoma. Ndezvipi zvinhu zvinotorwa zvinoshandura kuti pcb inogadzirwa sei, inodhura zvakadini, uye kuti ingaite sei. Muna 2025, vagadziri vanoramba vachitsvaga zvinhu zviri nani zvinobatsira nekupisa uye kutsigira matunhu matsva, epamberi.
Manufacturing Process
Kugadzirwa kwePWB
Kugadzira pwb kunotanga nekutora hwaro hwakakodzera. Mazhinji pwbs anoshandisa phenolic bepa kana epoxy girazi. Nhanho yekutanga ndeyekugadzira wiring pattern. Izvi zvinoitwa nephotolithography kana screen printing. Zvadaro, makemikari etching anobvisa imwe mhangura. Chete maronda anodiwa anogara pabhodhi. Izvi zvinoita hwaro hwegungano rekadhi redunhu.
Kare kare, vanhu vakagadzira pwbs nemaoko. Vakaisa uye vakanyora mapatani ivo pachavo. Iye zvino, michina inoita basa rakawanda. Automation inoita kuti zvinhu zvive nekukurumidza uye zvinobatsira kudzivirira kukanganisa. Takt nguva inoratidza kukurumidza kugadzirwa kweyuniti. Nguva yekuchinja inotaurira kuti mutsara unochinja sei zvigadzirwa. Defect density inoverenga mayunitsi akaipa mubatch. First pass goho rinoratidza kuti maunitsi mangani ari right kekutanga. Tafura iri pazasi inoronga nhamba dzakakosha dzekugadzira:

Mafekitori emazuva ano epwb anoshandisa simba shoma uye anoita zvikanganiso zvishoma. AI nemarobhoti anobatsira kuwedzera kuburitsa nepamusoro pe26%. Zvishandiso izvi zvinobatsira makambani kudzidza nekuvandudza nekukurumidza. Izvi zvinoreva kuti pwbs ikozvino inobata kupisa zvirinani uye inogara kwenguva refu.
Kugadzirwa kwePCB
Kuita pcb kunotanga nehwaro hwakasimba seFR-4 kana polyimide. Maitiro acho anoshandisa zvishandiso zvitsva senge laser yakananga imaging uye inkjet kudhinda. Multilayer lamination inoita kuti mabhodhi ave nematunhu akaomarara. Aya matanho anobatsira kugadzirisa kupisa zviri nani.
Mazhinji pcb mafekitori anoshandisa otomatiki mitsetse. Michina yekunhonga nekuisa inoiswa zvikamu zvinosvika 40,000 30 awa imwe neimwe. Izvi zvinokurumidza kupfuura zvingaitwa nevanhu nemaoko. Automation inodzikisira zvikanganiso uye inoderedza mitengo yevashandi kusvika pa70%. IoT inobatsira nekufungidzira kuchengetedza uye inoderedza nguva yekudzikira neXNUMX%. Makambani makuru anoshandisa marobhoti uye chaiyo-nguva cheki kuchengetedza mhando yepamusoro uye kutambisa yakaderera.
