Yiziphi izinto ezisetshenziswa ku-rigid-flex Boards?

Olunye uhlobo lwebhodi lesifunda oluya ngokuya luduma embonini ye-electronicsibhodi eliqinile-flex.

Uma kukhulunywa ngezinto zikagesi ezifana nama-smartphones namalaptop, ukusebenza kwangaphakathi kubaluleke njengengaphandle lesitayela. Izingxenye ezenza lezi zixhobo zisebenze zivame ukufihlwa ngaphansi kwezingqimba zebhodi lesifunda ukuze kuqinisekiswe ukusebenza kwazo nokuqina. Kodwa yiziphi izinto ezisetshenziswa kulawa mabhodi esekethe amasha?

I-PCB eguquguqukayo eqinileihlanganisa izinzuzo zamabhodi wesifunda aqinile futhi aguquguqukayo, anikeze isisombululo esiyingqayizivele samadivayisi adinga inhlanganisela yamandla emishini kanye nokuguquguquka. Lawa mabhodi awusizo ikakhulukazi ezinhlelweni ezibandakanya imiklamo eyinkimbinkimbi enezinhlangothi ezintathu noma amadivayisi adinga ukugoqwa noma ukugotshwa njalo.

Ake sibhekisise izinto ezisetshenziswa kakhulu ekwakhiweni kwe-PCB eqinile:

1. I-FR-4: I-FR-4 iyisisetshenziswa se-epoxy laminate esinganqamuki ilangabi esisetshenziswa kabanzi embonini yezogesi. Kuyinto esetshenziswa kakhulu engaphansi kwe-substrate kuma-PCB aqinile-flex. I-FR-4 inezici ezinhle kakhulu zokuhlukanisa ugesi namandla amahle okusebenza, okuyenza ilungele izingxenye eziqinile zamabhodi wesekethe.

2. I-Polyimide: I-Polyimide iyi-polymer ekwazi ukumelana nokushisa okuphezulu evame ukusetshenziswa njenge-flexible substrate material kumabhodi aqinile-flex. Inokuqina okuhle kakhulu kokushisa, izakhiwo zokufaka ugesi kanye nokuguquguquka kwemishini, okukuvumela ukuthi imelane nokugoba okuphindaphindiwe nokugoba ngaphandle kokuyekethisa ubuqotho bebhodi lesifunda.

3. I-Copper: I-Copper yiyona nto eyinhloko ye-conductive kumabhodi aqinile-flex. Isetshenziselwa ukudala ama-conductive traces kanye nokuxhumana okuvumela amandla kagesi ukuthi ageleze phakathi kwezingxenye ebhodini lesifunda. I-Copper ikhethwa ngenxa ye-conductivity yayo ephezulu, i-solderability enhle kanye nokusebenza kahle kwezindleko.

4. I-Adhesive: I-Adhesive isetshenziselwa ukuhlanganisa izingqimba eziqinile neziguquguqukayo ze-PCB ndawonye. Kubalulekile ukukhetha into enamathelayo engamelana nezingcindezi ezishisayo nezomshini ohlangabezana nazo ngesikhathi sokukhiqiza kanye nempilo yemishini. Izinamathiselo ze-Thermoset, njenge-epoxy resins, zivame ukusetshenziswa kuma-PCB aqinile-flex ngenxa yezakhiwo zawo ezinhle kakhulu zokubopha kanye nokumelana nokushisa okuphezulu.

5. I-Coverlay: I-Coverlay iyisendlalelo sokuzivikela esisetshenziselwa ukumboza ingxenye eguquguqukayo yebhodi lesifunda. Ngokuvamile yenziwe nge-polyimide noma into efanayo eguqukayo futhi isetshenziselwa ukuvikela imikhondo nezingxenye ezithambile ezicini zemvelo ezifana nomswakama nothuli.

6. Imaski ye-solder: Imaski ye-solder iyisendlalelo esiyisivikelo esinamekwe engxenyeni eqinile ye-PCB. Isiza ukuvimbela ibhuloho le-solder nezikhindi zikagesi kuyilapho ihlinzeka ngokuvikela nokugqwala.

Lezi izinto eziyinhloko ezisetshenziswa ekwakhiweni kwe-PCB eqinile nezimo.Kodwa-ke, kufanelekile ukuqaphela ukuthi izinto ezithile kanye nezakhiwo zazo zingahluka kuye ngokuthi ibhodi lisebenza kanjani kanye nokusebenza okufunayo. Abakhiqizi bavame ukwenza ngendlela oyifisayo izinto ezisetshenziswa kuma-PCB aguquguqukayo ukuze ahlangabezane nezimfuneko ezithile zedivayisi abasetshenziswa kuyo.

Ngokufigqiwe,ama-PCB aqinile aguquguqukayo ayintsha ephawulekayo embonini yezogesi, enikeza inhlanganisela eyingqayizivele yamandla emishini kanye nokuguquguquka. Izinto ezisetshenziswa njenge-FR-4, i-polyimide, ithusi, izinto ezinamathelayo, izimbondela, namamaski e-solder konke kudlala indima ebalulekile ekusebenzeni nasekuqineni kwalawa mabhodi. Ngokuqonda izinto ezisetshenziswa kuma-PCB aguquguqukayo aqinile, abakhiqizi nabaklami bangakha izisetshenziswa zikagesi ezisezingeni eliphezulu, ezinokwethenjelwa ezihlangabezana nezidingo zomhlaba wanamuhla oqhutshwa ubuchwepheshe.
