A bhodhi redunhu rakadhindwa (PCB) ibhodhi rakatetepa rakagadzirwa nefiberglass, composite epoxy, kana zvimwe zvinhu zvelaminate.MaPCB anowanikwa muzvikamu zvakasiyana-siyana zvemagetsi nemagetsi zvakaita semabhii, maredhiyo, radar, masisitimu emakombuta, nezvimwewo. Mhando dzakasiyana dzePCB dzinoshandiswa zvichibva pamashandisirwo.Ndeapi marudzi akasiyana ePCB?Verenga kuti uzive.

Ndeapi Mhando Dzakasiyana dzePCBs?

PCB's dzinowanzo kupatsanurwa pahwaro hwehuwandu, huwandu hwematehwe uye substrate inoshandiswa.Mamwe marudzi akakurumbira anokurukurwa pasi apa.

• Single Sided PCBs
  Single sided PCBs ndiyo mhando yemhando yemabhodhi edunhu, ane chikamu chimwe chete che substrate kana base zvinhu.Mutsara wakafukidzwa nesimbi yakatetepa, kureva mhangura- inova conductor yakanaka yemagetsi.Aya maPCB anewo inodzivirira solder mask, iyo inoiswa pamusoro pemhangura layer pamwe nejasi resiriki.Zvimwe zvakanakira zvinopihwa ne single sided PCB's ndezvi:
  • Single sided PCB's anoshandiswa kugadzira vhoriyamu uye ane mutengo wakaderera.
  • Aya maPCB anoshandiswa kune akareruka maseketi akadai semagetsi masensa, relays, sensors uye matoyi emagetsi.
• Kaviri Sided PCBs
  Kaviri mativi maPCB ane mativi ese eiyo substrate ine simbi conductive layer.Makomba ari mubhodhi redunhu anobvumira zvikamu zvesimbi kuti zvibatanidzwe kubva kune rumwe rutivi kuenda kune rumwe.Aya maPCB anobatanidza masekete kudivi ripi neripi nechero yezvirongwa zviviri zvekukwira, zvinoti kuburikidza-gomba tekinoroji uye pamusoro pegomo tekinoroji.Iyo tekinoroji yekuburikidza negomba inosanganisira kuisa zvikamu zvemutobvu kuburikidza nemakomba akafanocherwa pabhodhi redunhu, ayo anotengeswa kumapedhi kumativi akatarisana.Iyo yepamusoro-soro tekinoroji inosanganisira zvikamu zvemagetsi kuti zviiswe zvakananga pamusoro pepamusoro pemapuranga edunhu.Zvakanakira zvinopihwa nembiri mativi maPCB ndeaya:
  • Surface mounting inobvumira mamwe maseketi kuti abatanidzwe kubhodhi mukuenzanisa nekukwirisa-gomba.
  • Aya maPCB anoshandiswa mumhando dzakasiyana siyana dzekushandisa, kusanganisira nharembozha system, magetsi ekutarisa, bvunzo michina, amplifiers, nezvimwe zvakawanda.
• Multi-layer PCBs
  Multi-layer PCBs akadhindwa redunhu mapuranga, ayo anoumba anopfuura maviri akaturikidzana mhangura akaita 4L, 6L, 8L, etc. PCBs izvi kuwedzera michina inoshandiswa maviri mativi PCB wacho.Akasiyana-siyana akaturikidzana e substrate bhodhi uye insulating zvinhu zvinopatsanura zvidimbu mu-multi-layer PCBs.Iwo maPCB akakwana saizi, uye anopa mabhenefiti ehuremu nenzvimbo.Mamwe mabhenefiti anopihwa neakawanda-layer PCBs ndeaya:
  • Multi-layer PCBs inopa yakakwira mwero wedhizaini inoshanduka.
  • Aya maPCB anoita basa rakakosha mumaseketi ekumhanya.Vanopa imwe nzvimbo ye conductor pateni uye simba.
• MaPCB akaomarara
  Rigid PCBs dzinoreva idzo mhando dzePCB dzine hwaro hwezvinhu zvakagadzirwa kubva kune yakasimba zvinhu uye isingagone kubhenda.Zvimwe zvakakosha zvinopihwa navo:
  • Aya maPCB ane compact, ayo anovimbisa kusikwa kwakasiyana-siyana kwakaoma kutenderera kwakatenderedza.
  • Rigid PCBs inopa kugadzirisa kuri nyore uye kugadzirisa, sezvo ese maficha akanyorwa zvakajeka.Zvakare, nzira dzechiratidzo dzakarongeka.
• Flexible PCBs
  Flexible PCBs dzakavakwa pahwaro hwezvinhu zvinochinjika.Aya maPCB anouya mune rimwe divi, maviri-mativi uye akawanda mafomati.Izvi zvinobatsira mukuderedza kuoma mukati memusangano wemudziyo.Mamwe mabhenefiti anopihwa nemaPCB aya ndeaya:
  • Aya maPCB anobatsira kuchengetedza nzvimbo yakawanda, pamwe nekudzikisa huremu hwebhodhi rose.
  • Flexible PCBs inobatsira mukudzikisira saizi yebhodhi, izvo zvinoita kuti ive yakakodzera kune akasiyana maapplication uko yakakwira chiratidzo chetrace density inodiwa.
  • Aya maPCB akagadzirirwa mamiriro ekushanda, uko tembiricha uye density ndiyo inonyanya kunetseka.
• Rigid-Flex-PCBs
  Rigid flex PCBs ndiwo musanganiswa weakaomarara uye anochinjika edunhu mabhodhi.Iwo anosanganisira akawanda akaturikidzana emasekete anochinjika akasungirirwa kune anopfuura rigid board.
  • Aya maPCB akagadzirwa nemazvo.Nokudaro, inoshandiswa mune zvakasiyana-siyana zvekurapa uye zvechiuto.
  • Kuve kureruka-huremu, idzi PCB dzinopa 60% yehuremu uye nzvimbo yekuchengetedza.
• High-Frequency PCBs
  High-frequency PCBs anoshandiswa muhuwandu hwe500MHz - 2GHz.Aya maPCB anoshandiswa mune akasiyana frequency akakosha maapplication senge masisitimu ekutaurirana, microwave PCBs, microstrip PCBs, nezvimwe.
• Aluminium yakatsigirwa PCBs
  Aya maPCB anoshandiswa mumashandisirwo emagetsi epamusoro, sezvo kuvakwa kwealuminium kunobatsira mukupisa kupisa.Aluminium inotsigirwa nePCBs inozivikanwa kupa yakakwira mwero wekusimba uye yakaderera mwero wekuwedzera kwekupisa, izvo zvinoita kuti ive yakanaka kune maapplication ane yakakwira mechanic kushivirira.Iwo maPCB anoshandiswa kune maLED uye magetsi emagetsi.

Iko kudiwa kwePCBs kuri kubata munzvimbo dzakasiyana dzemaindasitiri.Nhasi, iwe uchawana zvakasiyana-siyana vane mukurumbira PCB vagadziri uye vanogovera, vanopa iyo inokwikwidza yekubatanidza zvishandiso musika.Zvinogara zvichikurudzirwa kutenga maPCB ekushandiswa kwemaindasitiri nekutengesa kubva kune vane mukurumbira vagadziri uye vatengesi.Twisted Traces ndomumwe akadaro akavimbika uye ane ruzivo vagadziri vemhando dzakasiyana dzePCB.Iyo kambani yagara ichipa vatengi vavo mabhodhi emhando yepamusoro-soro nekumhanya kwakanyanya, uye kuita.
