Umahluko ophambili phakathi kweebhodi ezinamacala amabini kunye ne-double-side rigid-flex

Intshayelelo:

Kweli nqaku, siza kuphonononga ezona mpawu ziphambili, iingenelo kunye nokungalungi kwe-PCBs enecala elinye kunye necala eliphindwe kabini.

Ukuba ukushishino lwe-elektroniki, usenokuba uye wadibana namagama anecala elinye kunye neebhodi ezinamacala amabini aqinileyo. Ezi bhodi zesekethe zisetyenziswa ngokubanzi kwizicelo ezahlukeneyo ze-elektroniki, kodwa ngaba uyawazi umahluko ophambili phakathi kwazo?

Phambi kokuntywila kwiinkcukacha eziphucukileyo, masiqale siqonde ukuba yintoni i-PCB eqinileyo. I-Rigid-flex luhlobo oluxubileyo lwebhodi yesekethe edibanisa ukuguquguquka kweebhodi zesekethe eziprintiweyo neziqinileyo. Ezi bhodi ziquka iileyile ezininzi ze-substrate eguquguqukayo eqhotyoshelwe kwibhodi enye okanye ngaphezulu eqinile. Ukudityaniswa kokuguquguquka kunye nokuqina kwenza uyilo oluntsonkothileyo olunemigangatho emithathu, ukwenza iiPCB eziguquguqukayo eziguquguqukayo zilungele usetyenziso apho indawo incinyiweyo.

Ngoku, makhe sixoxe ngomahluko phakathi kwebhodi enecala elinye kunye necala eliphindwe kabini eliguquguqukayo:

1. Ulwakhiwo:
I-PCB enecala elinye eqinile-eguquguqukayo iquka umaleko omnye we-substrate eguquguqukayo efakwe kwibhodi enye eqinileyo. Oku kuthetha ukuba isiphaluka sikhona kuphela kwicala elinye le-substrate eguquguqukayo. Kwelinye icala, i-PCB enamacala amabini eqinile iqulathe iileya ezimbini zesubstrates eziguquguqukayo ezincanyathiselwe kumacala omabini ebhodi eqinileyo. Oku kuvumela i-substrate eguquguqukayo ukuba ibe neesekethe kumacala omabini, ukwandisa ukuxinana kwamacandelo anokuthi afakwe.

2. Ukubekwa kwecandelo:
Kuba kukho ukujikeleza kwicala elinye kuphela, iPCB enecala elinye eqinileyo ibonelela ngesithuba esilinganiselweyo sokubekwa kwecandelo. Oku kunokuba ngumda xa kuyilwa iisekethe eziyinkimbinkimbi kunye nenani elikhulu lamacandelo. Iibhodi zeesekethe eziprintiweyo eziphindwe kabini ze-rigid-flex, ngakolunye uhlangothi, zivumela ukusetyenziswa ngokufanelekileyo kwendawo ngokubeka amacandelo kumacala omabini e-flexible substrate.

3. Ukuba bhetyebhetye:
Ngelixa zombini icala elinye kunye necala eliphindwe kabini le-PCBs eliguquguqukayo libonelela ngokuguquguquka, ukwahluka okumacala elinye ngokubanzi kubonelela ngokuguquguquka okukhulu ngenxa yolwakhiwo olulula. Oku bhetyebhetye okongeziweyo kubenza balungele usetyenziso olufuna ukugotywa okuphindaphindiweyo, njengezixhobo ezinxitywayo okanye iimveliso ezishukunyiswa rhoqo. Iibhodi zesekethe eziprintiweyo ezinamacala amabini, ngelixa ziguquguquka, zinokuqina kancinci ngenxa yokuqina okongeziweyo kwinqanaba lesibini le-substrate eguquguqukayo.

4. Ukuntsonkotha koMveliso:
Xa kuthelekiswa ne-PCB enamacala amabini, i-PCB enecala elinye eqinileyo ilula ukuyenza. Ukungabikho kweesekethe kwicala elinye kunciphisa ubunzima obubandakanyekayo kwinkqubo yokuvelisa. I-PCB enamacala amabini e-rigid-flex ine-circuit kumacala omabini kwaye ifuna ukulungelelaniswa okuchanekileyo kunye namanyathelo okuvelisa okongeziweyo ukuqinisekisa ukudibanisa okufanelekileyo kombane phakathi kweeleya.

5. Iindleko:
Ukusuka kumbono weendleko, iibhodi eziguquguqukayo ezinecala elinye zihlala zinexabiso eliphantsi kuneebhodi ezinamacala amabini aqinileyo. Izakhiwo ezilula kunye neenkqubo zokuvelisa zinceda ukunciphisa iindleko zoyilo lwecala elinye. Nangona kunjalo, iimfuno ezikhethekileyo zesicelo kufuneka ziqwalaselwe, njengoko kwezinye iimeko izibonelelo ezibonelelwa ngokuyila kabini zinokugqithisa iindleko ezongezelelweyo.

6.Uyilo lokuguquguquka:
Ngokumalunga nokuguquguquka koyilo, zombini i-PCB enecala elinye kunye ne-double-side rigid-flex inenzuzo. Nangona kunjalo, ii-PCB ezinamacala aphindwe kabini zibonelela ngamathuba oyilo olongezelelweyo kuba ukujikeleza kukho kumacala omabini. Oku kuvumela ukudibanisa okuyinkimbinkimbi ngakumbi, ingqibelelo yesignali engcono kunye nokuphucula ulawulo lwe-thermal.

Isishwankathelo

Iiyantlukwano eziphambili phakathi kweebhodi ze-single-side kunye ne-double-side-side rigid-flex ziyisakhiwo, amandla okubekwa kwecandelo, ukuguquguquka, ubunzima bokuvelisa, indleko kunye nokuguquguquka koyilo. IiPCB eziguquguqukayo kwicala elinye zibonelela ngokulula kunye neenzuzo zeendleko, ngelixa iiPCB ezinamacala aphindwe kabini zibonelela ngoxinaniso lwamacandelo aphezulu, okuphuculweyo okunokwenzeka koyilo, kunye nokubanakho ukomelezwa kwemfezeko yomqondiso kunye nolawulo lobushushu. Ukuqonda lo mahluko uphambili kuya kukunceda wenze isigqibo esinolwazi xa ukhetha i-PCB efanelekileyo kwisicelo sakho sombane.
