Yiziphi Izinhlobo Ezihlukene Zama-PCB?
Amayunithi e-PCB akhona ngezindlela eziningana zezinhlelo zokusebenza ezahlukahlukene. Ukukhetha ukwakheka okufanele komkhiqizo kuzodinga unjiniyela ukuthi acabangele ukusetshenziswa okuhlosiwe kwedivayisi, ubukhulu bayo kanye nemininingwane yamandla ayo. Buyekeza okulandelayo ukuze uqonde izinhlobo zamabhodi wesekethe aphrintiwe nokuthi yiziphi izinhlobo ezifanele imizamo yakho:
Ama-PCB ahlangothi olulodwa: Ukwenziwa kwe-PCB kuhilela ukwenza ibhodi lesekhethi ngesendlalelo esisodwa se-substrate kanye nesendlalelo esincane sensimbi. Zonke izingxenye zihlanganiswa ohlangothini olulodwa.
Ama-PCB anezinhlangothi ezimbili: Uhlobo lwe-PCB lapho kufakwa khona amashidi ensimbi aqhubayo kuzo zombili izinhlangothi ze-substrate.
Imigodi ingabholwa phakathi kwebhodi lesifunda ukuze kuvunyelwe ukuxhumana ukuthi kusebenze kuzo zombili izinhlangothi.
Ama-PCB Anezingqimba Eziningi: Okungenani ama-PCB amathathu anezingqimba ezimbili abekwe phezu komunye nomunye anezingqimba eziningana zokuvikela ukushisa ukuze kuncishiswe ukudluliselwa kokushisa. Ama-glue akhethekile anamathelayo agcina uchungechunge lwama-PCB luhlangene.
Ama-PCB Aguquguqukayo: Amabhodi wesekethe aphrintiwe abonisa ama-substrate aguquguqukayo ukusiza onjiniyela ukuthi bazivumelanise nezimo zomkhiqizo omncane. Ubuchwepheshe bungaba khona ngesimo sokwakhiwa okunezinhlangothi ezimbili, okunezinhlangothi ezimbili noma okunezingqimba eziningi.
Ama-PCB Aqinile: Awusizo emikhiqizweni yabathengi egcina isimo esifanayo phakathi nesikhathi sabo sokuphila. Ama-PCB aqinile akhiqizwa kusetshenziswa ama-substrate aqinile amelana nokusonteka.
Ama-PCB aqinile futhi aguquguqukayo: Amabhodi wesekethe aphrintiwe asebenzisa izinto eziqinile neziguquguqukayo. Lokhu kulungiselelwa kuvumela abathuthukisi bomkhiqizo ukuthi bonge isikhala, njengoba izindlela zokuxhuma eziqinile neziguquguqukayo zingafakwa ebhodini lesekethe elifanayo.
Ama-PCB asekelwe yi-aluminium: Uhlobo lwe-PCB oluthatha indawo ye-substrate ye-aluminium lapho i-fiberglass ingaba khona. Yakhelwe ukusetshenziswa ne-elekthronikhi ye-PCB enamandla amakhulu njengezibani ze-LED.
Ama-PCB anemvamisa ephezulu: Ibhodi lesekhethi elenzelwe ukuthumela amasignali anamandla njenge-2 GHz.
Akhiwa Ngani Ama-PCB?
Inqubo yokwenziwa kwe-PCB ibukeka ihlukile ngokusekelwe enjongweni ehlosiwe yeyunithi kanye nokuthi kungakanani amandla adingekayo ukuze idivayisi kagesi isebenze. Ngaphambi kokukhetha izinto zokuhlanganisa ibhodi lesifunda, kungumqondo omuhle ukuzijwayeza izingxenye ezine eziyinhloko zeyunithi ye-PCB:
I-substrate: Uhlaka lwesakhiwo sebhodi lesifunda — zonke izingxenye zinamathela kulobu buso.
Ama-Laminate: Izinto ezibamba zonke izendlalelo ze-PCB ndawonye.
Imaski yokusongelwa: Ihlala phezu kwama-foil ethusi ngenhloso yokuhlukanisa futhi ivikela ukuxhumana nezinto zemvelo.
Isikrini sesilika: Sinamathela kumaski we-solder ukuze izingxenye zikwazi ukulebula.
Kuyini uhlelo lwesakhiwo?
Umdwebo we-schematic, noma we-schematic, uwukubonakaliswa kwezakhi zesistimu esebenzisa izimpawu ezingabonakali, ezinemifanekiso esikhundleni sezithombe ezingokoqobo.

Yimuphi umehluko omkhulu: I-PCB eqinile vs i-flex PCB?
Umehluko omkhulu phakathi kwebhodi le-PCB eliqinile nebhodi le-PCB eliguquguqukayo yile:
1), Zikhiqizwa ngezinto ezahlukene: amabhodi wesekethe aqinile akhiqizwa yi-FR4, i-ceramic, i-metal core, i-PTFE njll., wonke aqinile (awakwazi ukugoba), kuyilapho ama-PCB aguquguqukayo ekhiqizwa yi-polyimide(PI), i-PET, i-Kapton matrial engagoba izikhathi eziyizinkulungwane;
2), Uma zingagobeka noma cha: i-PCB eqinile ayigobeka, kodwa i-PCB eguquguqukayo iyagobeka;
3), Zinezindlela ezahlukene zokusebenzisa: amabhodi esekethe aqinile asetshenziswa kumadivayisi kagesi angashukumi, kodwa amabhodi esekethe aguquguqukayo asetshenziswa kumadivayisi ahlala ehamba, njengamakhamera, ama-laptop, omakhalekhukhwini, ama-probe ahambayo njll.
