Kusindikizidwa Dera Board Chiyambi

A (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of substrate). Multi-layer PCBs allow for much higher component density, because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology.

Ma board ozungulira am'mbali-mbali ndi ovuta pang'ono kuposa PCB yokhala ndi mbali imodzi. Ma board awa amakhala ndi gawo limodzi lokha la gawo lapansi. Komabe, ali ndi zigawo conductive mbali iliyonse. Amagwiritsa ntchito mkuwa ngati zinthu zochititsa chidwi. Tiyeni tilowe mkati mwa PCB ya mbali ziwiri kuti tiphunzire zambiri!

Kapangidwe ndi Zida Zapawiri Sided PCB

Zinthu zapawiri za PCB zimatha kusiyanasiyana kutengera mtundu wa polojekiti. Komabe, zinthu zapakati zimakhala zofanana ndi matabwa onse ozungulira. Komabe, mawonekedwe a PCB amasiyana mtundu ndi mtundu.

Gawo laling'ono: Ndilo chinthu chofunikira kwambiri chopangidwa ndi fiberglass. Mutha kuziwona ngati mafupa a PCB.

Copper Layer: Itha kukhala zojambulazo kapena zokutira zonse zamkuwa. Ndicho chifukwa chake zimadalira mtundu wa bolodi. Zotsatira zake zimakhala zofanana ngati mumagwiritsa ntchito zojambulazo kapena zokutira zamkuwa. Ma board ozungulira am'mbali awiri amakhala ndi wosanjikiza wamkuwa wowongolera mbali zonse ziwiri.

Solder Mask: Ndi gawo loteteza la polima. Chifukwa chake, zimalepheretsa mkuwa kuti usakhale wozungulira. Mutha kuziwona ngati khungu la bolodi lozungulira. Kuwotchera kwapawiri kwa PCB ndi gawo lofunikira kwambiri pakukhazikika.

Silkscreen: ndi gawo lomaliza la silkscreen. Ngakhale ilibe gawo lililonse pakugwira ntchito kwa board board. Opanga amagwiritsa ntchito kuwonetsa manambala agawo. Nambala zagawo ndizofunika kwambiri pazolinga zoyesera. Kuphatikiza apo, mutha kusindikiza ma logos akampani yanu kapena zidziwitso zina mwanjira yamalemba.

Ubwino ndi Kuipa Kwa Mabodi Awiri Awiri A Circuit

Nazi zina mwazabwino ndi zoyipa zama board osindikizidwa a mbali ziwiri:

Ubwino wa Mabwalo Awiri Awiri Ozungulira

Ubwino Wapamwamba: Kukonzekera ndi kupanga PCB iyi kumafunikira ntchito yabwino. Zomwe zimapangitsa kuti pakhale ma boardboard apamwamba kwambiri.

Malo Okwanira a Zigawo: Imakhala ndi malo ochulukirapo a zigawo. Chifukwa mbali zonse za wosanjikiza ndi conductive.

Zosankha Zambiri Zopangira: Ili ndi zigawo zoyendetsera mbali zonse. Mukhoza kulumikiza zigawo zosiyanasiyana zamagetsi kumbali zonse ziwiri. Kotero muli ndi zosankha zambiri zamapangidwe.

Sourcing and Sinking Current: Pamene mukuigwiritsa ntchito ngati yosanjikiza pansi, mutha kuigwiritsa ntchito pakumira ndi kusefukira pano.

Kagwiritsidwe: Chifukwa chakuchita bwino, mutha kugwiritsa ntchito pazinthu zambiri.

Kuipa kwa matabwa amitundu iwiri

Mtengo Wokwera: Kupanga mbali zonse ziwiri kukhala zabwino, kumabwera pamtengo wokwera pang'ono.

Wopanga Waluso Akufunika: Pamafunika njira yovuta yopangira PCB ya mbali ziwiri kuti ipangidwe. Chifukwa chake, mumafunikira mainjiniya aluso kwambiri pazopanga zake.

Nthawi Yopanga: Nthawi yopanga ndi yopitilira PCB yam'mbali imodzi chifukwa chazovuta zake.

Kugwiritsa Ntchito Mabodi Awiri Awiri Ozungulira

Mtundu uwu wa bolodi wozungulira umachulukitsa kachulukidwe wadera. Amakhala osinthasintha komanso. Pafupifupi onse opanga ma PCB a mbali ziwiri amagwiritsa ntchito zida zambiri zamagetsi. Pansipa pali mawonekedwe odabwitsa a ma board a mbali ziwiri:

HVAC ndi kuyatsa kwa LED

Njira yoyendetsera magalimoto

Dashboards zamagalimoto

Kuwongolera ma relay ndi Mphamvu kutembenuka

Owongolera ndi magetsi

Kuyesa ndikuwunika zida zosiyanasiyana

Makina osindikizira ndi mafoni am'manja

Makina ogulitsa.
