Kodi ubwino wa bolodi lozungulira losindikizidwa losinthasintha ndi wotani?
Dongosolo losinthasintha lili ndi ubwino wa mawaya ambiri, kupepuka, makulidwe owonda, kupindika, kusinthasintha, ndi zina zotero.
Choyamba, imatha kupirira kupindika kwamphamvu mamiliyoni ambiri popanda kuwononga waya, kusuntha ndikukula momwe ikufunira malinga ndi zofunikira pa kapangidwe ka malo, kukwaniritsa kusonkhana kwa magawo atatu, ndikukwaniritsa zotsatira za kuphatikizana kwa kusonkhana kwa zigawo ndi kulumikizana kwa waya.
Kenako, ma PCB osinthasintha ali ndi mphamvu zamagetsi zabwino kwambiri. Chokhazikika cha dielectric chotsika chimalola kutumiza chizindikiro chamagetsi mwachangu; mphamvu zabwino za kutentha zimapangitsa kuti zikhale zosavuta kuziziritsa zigawo; kutentha kwakukulu kwa kusintha kwa galasi kapena malo osungunuka kumalola zigawozo kugwira ntchito bwino kutentha kwambiri.
Komanso, popeza timatha kusonkhanitsa zigawo zambiri za zigawo zolimba, ndipo gawo lopindika limagwiritsidwa ntchito polumikiza, kudalirika kwa kusonkhana ndi kuchuluka kwa ma PCB osinthasintha kumakhala kwakukulu.
Kodi kugwiritsa ntchito bolodi losinthasintha losindikizidwa ndi kotani?
Ma PCB osinthasintha amagwiritsidwa ntchito kwambiri muzipangizo zomwe zimakhudzidwa ndi makina chifukwa cha kusinthasintha kwawo kuti asagwedezeke. Malo omwe amagwiritsidwira ntchito afotokozedwa pansipa.
1) Makompyuta ndi zowonjezera
2) Ndege, ma drone, makamera
3) Magalimoto
4) Mafoni am'manja
5) Zipangizo zamagetsi zachipatala
6) Zipangizo zovalidwa
7) Ntchito zamafakitale: Mwachitsanzo, ma PCB osinthasintha amagwiritsidwanso ntchito m'makina amafakitale ndi makina owongolera kugawa mphamvu.
8) Zida zankhondo
9) Zamlengalenga
Kodi kusiyana pakati pa PCB yofewa ndi PCB yolimba ndi yofewa ndi kotani?
Ma PCB osinthasintha amapangidwa ndi zipangizo za PCB zosinthasintha zokha, monga PI ndi PET, pomwe PCB yosinthasintha yolimba imaphatikiza zinthu zolimba (nthawi zambiri zinthu za FR4) ndi zinthu zosinthasintha pamodzi. Chifukwa chake pama board osinthasintha, ma board onse osinthasintha amatha kupindika; koma pa PCB yosinthasintha yolimba, gawo linalake lokha lomwe zinthuzi zimasinthasintha limatha kupindika.
Kodi kukula kwa dzenje ndi ma pedi komwe kumakondedwa ndi ma PCB osinthasintha ndi kotani?
Zipangizo zina zopindika, monga Kapton, siziboola bwino ngati zipangizo wamba. 10 mils kapena kupitirira apo ndi zomwe zimakondedwa pa kukula kochepa, kokha mu gawo lopindika. Zipangizo zolimba zopindika zimafanana ndi specs za bolodi lolimba. Kukula kwa Pad, njira yopangira plating ya flex ndi ya mgolo wokha (khoma la dzenje).
