A Buga kewaye hukumar (PCB) ne zuwa kashi Single-Gefe Boards , biyu mai gefe Boards da Multi-Layer Boards.
Na farko shi ne Single-Mai Gefe Boards, a kan mafi asali PCB, inda sassan sun mayar da hankali a gefe daya da kuma wayoyi a kan other.Because da waya ne kawai a gefe daya, shi ne ake kira Single-Gefe Boards, da Single-Mai Gefe allon ne yawanci sauki yin da low a kudin, amma rashin kyaunta shine cewa shi ba za a iya amfani da su ma hadaddun kayayyakin.
The biyu mai gefe Boards sigar tsawo na Single-Gefe Boards, da kuma lokacin da guda-Layer wayoyi ba zai iya biyan bukatun da lantarki samfurin, biyu mai gefe Boards ne used.Both bangarorin an rufe tare da jan karfe waya, da kuma iya wuce ta rami ya shiryar da layi tsakanin biyu yadudduka haka kamar yadda ta samar da ake bukata na hanyar sadarwa.
Multi-Layer Boards ne a bugu farantin cewa yana da uku yadudduka na conductive hoto Layer da insulating abu a tsakanin, kuma conductive jadawali ne interlinked bisa ga requirement.The multilayer kewaye hukumar aka samfurin na ci gaban wutar lantarki da bayanai da fasaha zuwa high gudun, Multi-aiki, manyan iya aiki, karamin girma, bakin ciki da irin da haske nauyi.
Bisa ga halaye, da buga kewaye hukumar ne zuwa kashi m jirgin (FPC) , m jirgin (PCB) , flexi da m jirgin (FPCB).
A buga kewaye allon yafi hada da waldi gammaye, ramukan, hawa ramukan, wayoyi, aka gyara, haši, fillers, lantarki iyakoki, da dai sauransu
Babban ayyuka na kowane bangaren su ne kamar haka:
Welding kushin: a PTH rami amfani ga waldi fil na wani bangaren.
Ta hanyar rami: PTH ta rami da kuma NPTH ta hanyar rami, da PTH ta hanyar rami ake amfani da su gama da aka gyara tsakanin aka gyara.
Hawa ramuka: amfani ga tsayayyen buga kewaye allon.
Wayoyi: lantarki sadarwa jan film amfani to connect da dari na gyara.
Connector: a bangaren amfani don a haɗa a buga kewaye hukumar.
Fillers: jan amfani da ƙasa waya cibiyar sadarwa zai iya yadda ya kamata rage impedance.
Banana iyaka: amfani domin sanin girman da buga kewaye hukumar, kuma babu gyara a buga kewaye hukumar iya wuce iyakar.
A takaice dai, da buga kewaye hukumar tushe kayan da yafi hada da uku da manyan albarkatun kasa kamar tagulla tsare, guduro, da kuma karfafa ayyukansa abu.
FR-4 ne na kowa abu don buga kewaye hukumar (PCBs), kuma yana da yawa maki da kuma iri kamar TG130, TG150, High KU 170 da kuma 180 da dai sauransu, mafi buga kewaye allon suna kerarre amfani da gilashi mai-karfafa epoxy laminate matsayin substrate, yayin da akwai wani m iri-iri laminates samuwa a kasuwa, FR-4 ne duka biyu m da kuma da-karbuwa a matsayin wani misali abu don PCB yi . FR-4 ayyuka da kyau a matsayin lantarki insulator, kuma yana da kyau ƙarfi-to-nauyi rabo, kuma shi ne harshen resistant.
Tare da ƙara m gasar a kasuwa, a layi tare da qa'ida ta " high management , da tsauraran sharu , high quality , kuma mãdalla da sabis ", da kuma exerting da abũbuwan amfãni a kasuwar, da fasaha, da kuma talanti, KingSong samar da mu abokan ciniki tare da mafi ingancin da kuma azumi samfurori da kuma ayyuka.
