Ukulinganiselwa kosayizi nokuma kwamabhodi esekethe aguquguqukayo

Kulokhu okuthunyelwe kwebhulogi, sizohlola usayizi nokulinganiselwa komumo wamabhodi esekethe aguquguqukayo nokuthi le mikhawulo ithinta kanjani ukukhetha kokuklama.

Amabhodi esekethe aguquguqukayo, awaziwa nangokuthi ama-PCB avumelana nezimo, aguqule imboni yezogesi ngekhono lawo eliyingqayizivele lokugoba nokuzivumelanisa nezimo ezihlukahlukene. Lawa mabhodi avumelana nezimo avula amathuba amasha okuklama amadivaysi e-elekthronikhi amancane, alula, futhi asebenza ngezindlela eziningi. Kodwa-ke, njenganoma yibuphi obunye ubuchwepheshe, kunemikhawulo ethile okufanele icatshangelwe lapho kusetshenziswa amabhodi esekethe aguquguqukayo.

Imikhawulo kasayizi wamabhodi esekethe aguquguqukayo:

Amabhodi wesifunda aguquguqukayo anezinzuzo ezinkulu ngaphezu kwama-PCB aqinile uma kukhulunywa ngosayizi. Ukuguquguquka kwabo kuvumela imiklamo ehlangene kanye nekhono lokungena ezindaweni eziqinile. Nokho, kunemikhawulo ethile yosayizi okufanele uyikhumbule.

1. Ububanzi nobude:Ububanzi nobude bebhodi lesifunda eliguquguqukayo kunqunywa ubukhulu bezinto ezisetshenziswayo ze-substrate. Izinto ezivamile ezifana ne-polyimide noma i-Mylar zivame ukuza ngosayizi abajwayelekile, zikhawulela ububanzi nobude obukhulu bebhodi lesifunda. Lobu bukhulu obujwayelekile bungase buhluke kuye ngomkhiqizi, kodwa ngokuvamile busukela kumayintshi ambalwa ukuya kumafidi ambalwa.

2. Ubukhulu:Amabhodi wesifunda aguquguqukayo ngokuvamile aba mncane kunamabhodi esekethe aqinile. Ugqinsi lwe-PCB eguquguqukayo lunqunywa impahla engaphansi kanye nogqinsi lwanoma yiziphi izendlalelo ezengeziwe, njengeminonjana yethusi noma imaski ye-solder. Lezi zingxenye zandisa ubukhulu bebhodi futhi kufanele zicatshangelwe phakathi nenqubo yokuklama. Amabhodi azacile anikeza ukuguquguquka okwengeziwe kodwa angase abe sengozini yokulimala.

Imikhawulo yomumo yamabhodi esekethe aguquguqukayo:

Amabhodi esekethe aguquguqukayo anomumo oguquguqukayo. Ikhono lazo lokugoba nokuvumelana nezinhlobonhlobo zamajometri lenza imiklamo emisha. Noma kunjalo, kusekhona ezinye izithiyo zomumo okufanele zibhekwe.

1. Irediyasi egobayo:Irediyasi egobayo iyisici esibalulekile okufanele icatshangelwe lapho uklama amabhodi esekethe aguquguqukayo. Isho irediyasi encane yokugoba ibhodi lesekethe elingamelana nayo ngaphandle kokulimaza iminonjana noma izingxenye. I-radius yokugoba inqunywa ukujiya kanye nezakhiwo ezibonakalayo ze-substrate. Ngokuvamile, ibhodi liba mncane, i-radius egobayo iba mincane. Ishidi ledatha lomkhiqizi noma imihlahlandlela kufanele ngaso sonke isikhathi kuxhunyanwe nayo ukuze kuqinisekiswe ukuthi imingcele eguquguqukayo yebhodi ayeqiwa.

2. Izimo eziyinkimbinkimbi:Ngenkathi amabhodi esekethe aguquguqukayo ekwazi ukugoba futhi agoqe, ukudala izimo eziyinkimbinkimbi ze-3D kungaba inselele. Ama-engeli acijile, ukugoqeka okuyinkimbinkimbi, noma amajika amaningi ayinkimbinkimbi angagcizelela okubalulekile kwebhodi futhi kwehlise ubuqotho balo. Abaqambi kufanele bacabangele ngokucophelela ukulinganiselwa kwezinto ezibonakalayo futhi baqinisekise ukuthi ukwakheka okufunayo kungafinyelelwa ngaphandle kokufaka ingozi yokwehluleka.

Lungiselela idizayini ngokuvumelana nezimo engqondweni yamabhodi esekethe aguquguqukayo:

Naphezu kokulinganiselwa kwabo, amabhodi wesifunda aguquguqukayo anikeza izinzuzo eziningi. Ukuqinisekisa ukwakheka okuhle, usayizi kanye nezithiyo zomumo kufanele kucatshangelwe zisuka nje. Nawa amanye amathiphu okuthuthukisa idizayini yakho ye-PCB eguquguqukayo:

1. Hlola nomkhiqizi:Umkhiqizi ngamunye angase abe nosayizi ohluke kancane nemikhawulo yomumo. Kubalulekile ukuthintana nomkhiqizi omkhethile kusenesikhathi enqubweni yokuklama ukuze uqonde imikhawulo yabo ethile kanye nokuklama ngendlela efanele.

2. Sebenzisa amathuluzi okulingisa:Kunezinhlobonhlobo zamathuluzi okulingisa angasiza ekuhlaziyeni ukuziphatha komzimba kwamabhodi esekethe aguquguqukayo ngaphansi kwezimo ezihlukene zokugoba. Lawa mathuluzi angasiza ekunqumeni i-bend radii, ukugxilwa kwengcindezi kanye namaphuzu okuhluleka okungenzeka, okuvumela abaklami ukuthi benze izinqumo ezinolwazi.

3. Ukuvumelana nezimo:Uma uklama ngama-PCB aguquguqukayo, kuwukuhlakanipha ukuhlanganisa izici zedizayini ezengeziwe ukuze kuthuthukiswe ukuguquguquka. Isibonelo, ukunikeza isikhala esanele phakathi kwezingxenye nokulandela kungenza kube lula ukuthi ibhodi ligobe ngaphandle kokudala umonakalo noma ukufinyela.

Ekuphetheni, kuyilapho amabhodi wesifunda aguquguqukayo enikeza izinzuzo eziningi, kubalulekile ukukhumbula usayizi wabo nokulinganiselwa komumo.Ngokuqonda nokusebenza ngaphakathi kwalezi zingqinamba, abaklami bangakha amadivaysi e-elekthronikhi amasha futhi athembekile. Ngokuhlela okufanele, ukubonisana nabakhiqizi, kanye nokusetshenziswa kwamathuluzi okulingisa, idizayini ye-PCB eguquguqukayo ingacindezela ngempumelelo imingcele yosayizi nokuma ukuze yakhe imikhiqizo ye-elekthronikhi esebenza kahle futhi ephakeme kakhulu.
