Gudiga wareegga daabacan (PCBS) waa xaashiyo ka samaysan fiberglass, resin epoxy composite ama qalab kale oo la dahaadhay. PCBS waxaa laga heli karaa qaybo kala duwan oo koronto iyo elektiroonig ah (tusaale, buzzers, radio, radars, nidaamyada kombiyuutarka, iwm). Noocyo kala duwan oo PCBS ah ayaa la isticmaali karaa iyadoo ku xiran codsiga. What are the various types of PCBS? Akhri si aad u ogaato.

What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. Qaar ka mid ah noocyada caanka ah ayaa hoos looga hadlay.

L PCB hal dhinac ah

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. Lakabka waxaa lagu daboolay bir khafiif ah, naxaas ah, taas oo ah kaariye wanaagsan oo koronto. PCBS -yadu waxay sidoo kale ka kooban yihiin lakab iska -caabbinta alxanka oo lagu dabaqo dusha sare ee lakabka naxaasta iyadoo lala kaashanayo dahaarka silkscreen. Qaar ka mid ah faa’iidooyinka ay PCBS-da hal dhinac ah bixiyaan waa:

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

PCBS -kan waxaa loo adeegsadaa wareegyada fudud sida dareemayaasha korontada, gudbinta, dareemeyaasha iyo alaabta carruurtu ku ciyaarto.

L PCB laba-dhinac leh

Labada dhinac ee PCB-ga labada dhinac leh waxay leeyihiin lakabyo tabiya biraha. Godadka ku yaal guddiga wareegga ayaa u oggolaanaya in qaybo bir ah lagu xiro dhinac ilaa dhinac. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. Farsamaynta daloolku waxay ku lug leedahay in la mariyo shirka macdanta ledhka iyada oo loo marayo dalool hore loo qoday oo ka mid ah sabuuradda ka dibna lagu dhejiyo suufka dhinaca ka soo horjeeda. Kordhinta dusha sare waxay ku lug leedahay in si toos ah loogu dhejiyo qaybaha korontada dusha sare ee wareegga. PCBS-yada labada dhinac leh waxay bixiyaan faa’iidooyinka soo socda:

Kordhinta dusha ayaa u oggolaanaysa wareegyo badan in lagu xiro sabuuradda marka loo eego dhejinta daloolka.

PCBS -kan waxaa si weyn loogu adeegsadaa nidaamyada taleefanka gacanta, la socodka awoodda, qalabka tijaabada, cod -weyneyaasha iyo codsiyo kale oo badan.

L multilayer PCB

PCB multilayer waa guddi wareeg oo daabacan oo ka kooban in ka badan laba lakab oo naxaas ah, sida 4L, 6L, 8L, iwm. PCBS-yadu waxay fidiyaan tiknoolajiyadda loo isticmaalo PCBS-yada labada dhinac leh. Lakabyada substrate-ka iyo dahaarka waxay kala soocaan lakabyada PCB-ka-badan. PCBS are compact in size and offer weight and space advantages. Qaar ka mid ah faa’iidooyinka PCBS -yada badan ay bixiyaan waa:

PCBS-yada lakabyada badan leh ayaa bixiya dabacsanaanta naqshadeynta heer sare.

PCBS-yadu waxay door muhiim ah ka ciyaaraan wareegyada xawaaraha sare leh. Waxay siiyaan boos badan qaababka kaariyeyaasha iyo ilaha awooda.

L PCB adag

PCBS -yada adag waa kuwa laga sameeyay walxo adag oo aan la laaban karin. Qaar ka mid ah faa’iidooyinka muhiimka ah ee ay bixiyaan:

PCBS -yadaani waa kuwo is haysta, iyagoo hubinaya in wareegyo kala duwan oo kakan laga abuuro agagaarkooda.

PCBS -yada adag way fududahay in la dayactiro lana dayactiro maxaa yeelay dhammaan qaybaha si cad ayaa loo calaamadeeyay. Waxaa intaa dheer, dariiqyada signalada ayaa si fiican loo habeeyay.

L PCB dabacsan

PCB -ga dabacsan ayaa lagu dhisay agab saldhig oo dabacsan. These PCBS are available in single-sided, double-sided and multi-layer formats. Tani waxay kaa caawineysaa yareynta kakanaanta qaybaha qalabka. Some of the advantages these PCBS offer are:

PCBS -yadaani waxay caawiyaan badbaadinta meel badan waxayna yareeyaan miisaanka guud ee guddiga.

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

PCBS -yadaan waxaa loogu talagalay xaaladaha hawlgalka ee heerkulka iyo cufnaanta la tixgeliyo.

L Adag -dabacsan -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. Natiijo ahaan, waxaa loo adeegsadaa codsiyo caafimaad iyo ciidan oo kala duwan.

PCBS -yadaani waa kuwo khafiif ah, oo badbaadinaya ilaa 60% miisaanka iyo booska.

L PCB-noqnoqoshada sare

Hf PCBS are used in the frequency range of 500MHz to 2GHz. PCBS -kan waxaa loo adeegsan karaa codsiyada soo noqnoqda ee kala duwan, sida nidaamyada isgaarsiinta, PCBS microwave, PCBS microstrip, iwm.

L Aluminium gadaal PCB

Taargooyinkaan waxaa loo adeegsadaa codsiyada awoodda sare leh maxaa yeelay qaab-dhismeedka aluminiumku wuxuu caawiyaa kala-firdhinta kuleylka. PCBS-yada Aluminium-ka taageera ayaa la og yahay inay leeyihiin heerar sare oo adayg iyo heerar hoose oo fidinta kuleylka, taasoo ka dhigaysa kuwo ku habboon codsiyada leh dulqaadyo farsamo oo sarreeya. PCB waxaa loo isticmaalaa korontada iyo korontada.

Baahida loo qabo PCBS -da ayaa soo gaadhay warshadaha oo dhan. Maanta, waxaad ka heli doontaa noocyo kala duwan oo soosaarayaasha PCB-ga si fiican loo yaqaan iyo qaybiyayaal oo dabooli kara baahiyaha suuqa qalabka ee ku xiran tartanka. Waxaa had iyo jeer lagu talinayaa in laga iibsado PCBS -ka warshadaha iyo isticmaalka ganacsiga soo -saarayaasha sumcadda leh iyo alaab -qeybiyeyaasha.
