What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. Diẹ ninu awọn oriṣi olokiki ni a jiroro ni isalẹ.

L nikan-apa PCB

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. Layer ti wa ni bo pẹlu irin tinrin, bàbà, eyiti o jẹ adaorin ina to dara. Awọn PCBS wọnyi tun ni Layer resistance alatako aabo kan ti o lo si oke ti fẹlẹfẹlẹ bàbà ni idapo pẹlu ibora siliki. Diẹ ninu awọn anfani ti PCBS apa-ọkan nfunni ni:

Single-sided PCB is used for mass production and low cost.

Awọn PCBS wọnyi ni a lo ni awọn iyika ti o rọrun bii awọn sensọ agbara, awọn isọdọtun, awọn sensosi ati awọn nkan isere itanna.

L double-sided PCB

Awọn ẹgbẹ mejeeji ti PCB ni iha meji ni awọn fẹlẹfẹlẹ irin. Awọn iho ninu igbimọ Circuit gba awọn ẹya irin laaye lati sopọ lati ẹgbẹ kan si ekeji. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. Ilana ọna-iho pẹlu gbigbe apejọ ijọ kọja nipasẹ iho ti a ti kọ tẹlẹ ninu igbimọ ati lẹhinna alurinmorin si paadi ni apa idakeji. Iṣagbesori dada pẹlu gbigbe awọn paati itanna taara lori dada ti igbimọ Circuit kan. Awọn PCBS apa meji nfunni awọn anfani wọnyi:

Gbigbe dada gba awọn iyika diẹ sii lati sopọ si igbimọ ju nipasẹ iṣagbesori iho.

Awọn PCBS wọnyi ni lilo pupọ ni awọn eto foonu alagbeka, ibojuwo agbara, ohun elo idanwo, awọn amplifiers ati ọpọlọpọ awọn ohun elo miiran.

L multilayer PCB

PCB multilayer jẹ igbimọ Circuit ti a tẹjade ti o ni diẹ sii ju awọn fẹlẹfẹlẹ idẹ meji, bii 4L, 6L, 8L, abbl. Awọn PCBS wọnyi fa imọ-ẹrọ ti a lo ni awọn PCBS apa meji. Awọn fẹlẹfẹlẹ ti sobusitireti ati idabobo sọtọ awọn fẹlẹfẹlẹ ni PCB ti ọpọlọpọ-fẹlẹfẹlẹ. PCBS are compact in size and offer weight and space advantages. Diẹ ninu awọn anfani ti PCBS multilayer nfunni ni:

PCBS ti ọpọlọpọ-ipele pese iwọn giga ti irọrun apẹrẹ.

Awọn PCBS wọnyi ṣe ipa pataki ni awọn iyika iyara to gaju. Wọn pese aaye diẹ sii fun awọn apẹẹrẹ adaorin ati awọn orisun agbara.

L kosemi PCB

Awọn PCBS lile jẹ awọn ti o jẹ ti ohun elo to lagbara ati pe a ko le tẹ. Diẹ ninu awọn anfani pataki ti wọn funni:

Awọn PCBS wọnyi jẹ iwapọ, ni idaniloju pe ọpọlọpọ awọn eka iyika ni a ṣẹda ni ayika wọn.

Awọn PCBS lile jẹ rọrun lati tunṣe ati ṣetọju nitori gbogbo awọn paati ti samisi ni kedere. Pẹlupẹlu, awọn ọna ifihan ti ṣeto daradara.

L rọ PCB

PCB ti o rọ jẹ itumọ lori awọn ohun elo ipilẹ ti o rọ. These PCBS are available in single-sided, double-sided and multi-layer formats. Eyi ṣe iranlọwọ idinku idiju laarin awọn paati ẹrọ. Some of the advantages these PCBS offer are:

Awọn PCBS wọnyi ṣe iranlọwọ fifipamọ aaye pupọ ati dinku iwuwo gbogbogbo ti igbimọ.

Flexible PCBS help reduce board size and are therefore ideal for a variety of applications requiring high signal routing density.

Awọn PCBS wọnyi jẹ apẹrẹ fun awọn ipo iṣẹ ninu eyiti a gbero iwọn otutu ati iwuwo.

L Kosemi -rọ -PCB

Rigid flexible – A PCB is a combination of rigid and flexible circuit boards. They consist of multiple layers of flexible circuits connected to more than one rigid plate.

These PCBS are precisely constructed. Bi abajade, a lo ni ọpọlọpọ awọn ohun elo iṣoogun ati ologun.

Awọn PCBS wọnyi jẹ iwuwo fẹẹrẹ, fifipamọ to 60% ti iwuwo ati aaye.

L ga-igbohunsafẹfẹ PCB

Hf PCBS are used in the frequency range of 500MHz to 2GHz. Awọn PCBS wọnyi le ṣee lo ni ọpọlọpọ awọn ohun elo igbohunsafẹfẹ to ṣe pataki, gẹgẹbi awọn eto ibaraẹnisọrọ, PCBS microwave, PCBS microstrip, abbl.

L Aluminiomu backplane PCB

Awọn awo wọnyi ni a lo fun awọn ohun elo agbara-giga nitori igbe aluminiomu ṣe iranlọwọ lati tuka ooru. Awọn PCBS ti o ṣe atilẹyin Aluminiomu ni a mọ lati ni awọn ipele giga ti lile ati awọn ipele kekere ti imugboroosi igbona, ṣiṣe wọn ni apẹrẹ fun awọn ohun elo pẹlu awọn ifarada ẹrọ giga. PCB ti lo fun LED ati ipese agbara.

Ibeere fun PCBS n wa kọja awọn ile -iṣẹ. Loni, iwọ yoo rii ọpọlọpọ awọn olupese PCB olokiki ati awọn olupin kaakiri ti o le pade awọn iwulo ti ọja ohun elo ifigagbaga ti o sopọ. O jẹ iṣeduro nigbagbogbo lati ra PCBS fun ile -iṣẹ ati lilo iṣowo lati ọdọ awọn aṣelọpọ olokiki ati awọn olupese.
