Daban-daban na allon kewayawa

The buga kewaye hukumar ko PCB shine allon goyan bayan jiki yayin haɗa kayan lantarki daban-daban na mafi girman tsarin. Allon kewayawa yana amfani da wayoyi masu ɗaukar nauyi, padding da sauran abubuwa waɗanda ke fitowa daga layin jan ƙarfe.

Gefe daya

Kamar yadda sunan ke nunawa, ana yin PCB mai gefe ɗaya daga abu ɗaya, wanda kuma aka sani da “substrate.” On top of the base is a thin foil layer made of copper. This acts as a conductor of electrical signals.

Waɗannan su ne mafi yawan nau’ikan PCBS kuma sun shahara sosai wajen samar da ƙara saboda ƙarancin farashi. Ana samun waɗannan allunan a kyamarori, ƙididdiga da kayan aikin rediyo.

Hakanan ana iya samun su a cikin ƙirar kayan wasa masu sauƙi.

Bangarorin biyu

Double-sided printed circuit boards work much like single-sided printed circuit boards, but are sandwiched between conductive layers on both sides. In addition, they are designed to have holes drilled into the plate.

These holes are placed on the board to allow the circuit to be mounted on either side of the PCB or fed through the board. Additional flexibility and conductive surfaces allow double-sided materials to be used in more advanced applications.

Ana yawan samun PCBS mai gefe biyu a cikin wayoyin hannu, injinan siyarwa, na’urorin mota da kayan aikin mitar wutar lantarki.

Mai Girma

Zane yana da gefe biyu kuma yana faɗaɗa akan shi. Multilayer tarin ne wanda bai gaza uku (3) PCBS mai fuska biyu ba. Suna ɗaukar fasahar da aka kafa a nan kuma suna ƙara ƙarfin samar da su.

Size and space are the main advantages of multi-layer PCBS. Suna iya amfani da allon multilayer maimakon alluna da yawa.

Su wani sashe ne mai mahimmanci na da’irori masu sauri saboda girman allon su yana ba da damar tsarar madugu da ƙarfi.

Taurin kai

Rigid PCBS can be single, double, or multi-layered. Rigidity yana nufin kayan da ake amfani da su daga abin da aka yi allunan. When a PCB is rigid, it is, as the name implies, made of materials that resist distortion or deformation.

A very common rigid PCB is the motherboard on a computer. An tsara su don zama masu ɗorewa kuma ana iya amfani da su a wuri ɗaya da siffar.

Rigid PCBS benefit from ease of maintenance and ease of use. Duk ayyukan suna da wuri kuma suna da alama a fili lokacin da aka tsara su. Ba’a iyakance su ga ƙira ɗaya ba kuma suna iya kewayawa daga layi ɗaya zuwa ƙirar PCB Layer goma (10).

PCBS mai sassauƙa yana aiki daidai da m PCBS, amma an yi su da abubuwa daban-daban.

Ana yin faranti masu kauri da abubuwa masu ɗorewa (ma’ana riƙe siffarsu) (yawanci cakuda fiberglass), yayin da faranti masu sassauƙa yawanci ana yin su da filastik ko makamantansu.

Literal flexibility is the main advantage of flexible PCBS. Tattaunawar kuɗi yana yiwuwa saboda ikon su na “nannade” wuraren da tsayayyen faranti na iya yin tafiya.

The main applications of flexible PCBS are in systems that may cause damage to the environment. Tsarin su yana sa su zama masu juriya ga zafin jiki, ruwa, lalata da sauran abubuwan da zasu iya lalata faranti mai tsauri.

Mixing and soft

Rigid-flexibility Bridges the gap between the two types built on text and graphics, which is most common in mobile phones and digital cameras.

Waɗannan sun haɗa da saitin da’irori masu sassauƙa da aka haɗa zuwa faranti masu tsauri da yawa. Wannan ya sa zane ya fi sauƙi, yayin da yake haɗuwa da duk abubuwan da ake bukata don waɗannan sassa a cikin wani ɓangare na “daya”.

Hakanan ana iya samun tauri da sassauci a aikace-aikacen likita.

Aluminum baya

Rashin zafi yana tsakiyar PCB. Lokacin da tsarin zafin jiki ya kasance abin la’akari, yin amfani da PCB na baya na aluminium shine mafi kyawun zaɓi, wanda ya haɗa da wasu fa’idodin bayyane.

Tsarin PCB yayi kama da daidaitaccen Layer guda ɗaya ko biyu, amma kayan da ake amfani da su sun bambanta.

Sun fi ɗorewa kuma suna da alaƙa da muhalli. Aluminum ba mai guba bane kuma yana da sauƙin sake yin fa’ida. On top of that, it’s incredibly cheap, it’s one of the cheapest metals in mining, and it’s cheap to make.

Mitar girma

Hf PCBS ba a gina su ta sabuwar hanya ba, misali, kwatanta guda ɗaya zuwa yadudduka da yawa, amma koma ga nau’in amfani. Ana iya amfani da PCBS mai girma lokacin da ake buƙatar watsa sigina akan ƙimar sama da 1GHz. They are mainly used in large communication systems.

Duk da yake kowane nau’in allon yana da fa’idodinsa, akwai fa’idodi da yawa don amfani da PCB gabaɗaya.
