Kitapo boribory vita pirinty (PCBS) dia takelaka vita amin’ny fiberglass, resin epoxy mitambatra na fitaovana vita amin’ny lamina hafa. Ny PCBS dia hita amin’ny fitaovana elektrika sy elektronika isan-karazany (oh: buzzer, radio, radara, rafitry ny solosaina, sns.). Ny karazana PCBS samihafa dia azo ampiasaina arakaraka ny fampiharana. What are the various types of PCBS? Vakio eo ho fantatra.

What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. Misy karazana malaza sasany resahina etsy ambany.

L PCB tokana

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. The layer is covered with a thin metal, copper, which is a good conductor of electricity. Ireo PCBS ireo koa dia misy sosona fanoherana miaro izay apetaka eo an-tampon’ny sosona varahina miaraka amin’ny firakotra silkscreen. Ny sasany amin’ireo tombony atolotry ny PCBS tokana dia:

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

Ireo PCBS ireo dia ampiasaina amin’ny boriborintany tsotra toy ny sensor elektrika, ny relay, ny sensor ary ny kilalao elektronika.

L double-sided PCB

Ny andaniny roa amin’ny PCB misy sisiny roa dia misy sosona fitondra vy. Ny lavaka ao amin’ny solaitrabe dia mamela ny ampahany metaly hifandray amin’ny lafiny iray mankany amin’ny ilany. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. Ny teknikan’ny famoahana dia mitaky fandalovana ilay fivorian’ny firaka amin’ny loaka efa voaroboka mialoha ao anaty tabilao ary avy eo mifatotra amin’ny pad amin’ny lafiny mifanohitra. Ny fametahana ny etona dia mitaky fametrahana singa elektrika mivantana eo ambonin’ny vatan’ny faritra. PCBS misy lafiny roa manolotra ireto tombony manaraka ireto:

Ny fametahana ambonimbony dia ahafahan’ny boriborintany mifandray amin’ny tabilao kokoa noho ny amin’ny alàlan’ny fametrahana lavaka.

Ireo PCBS ireo dia be mpampiasa amin’ny rafi-telefaona finday, fanaraha-maso herinaratra, fitaovana fitsapana, fanamafisam-peo ary fampiharana maro hafa.

L multilayer PCB

Ny PCB multilayer dia takelaka misy pirinty misy sosona varahina mihoatra ny roa, toy ny 4L, 6L, 8L, sns. Ireo PCBS ireo dia manitatra ny teknolojia ampiasaina amin’ny PCBS misy lafiny roa. Ny soson’ny substrate sy ny insulation dia manavaka ny sosona ao anaty PCB marobe. PCBS are compact in size and offer weight and space advantages. Ny sasany amin’ireo tombony omen’ny PCBS multilayer dia:

Ny multi-layer PCBS dia manome mari-pahaizana avo lenta amin’ny famolavolana endrika.

Ireo PCBS ireo dia mitana andraikitra lehibe amin’ny haingam-pandeha haingam-pandeha. Manome toerana bebe kokoa ho an’ny lamina sy ny loharanom-pahefana izy ireo.

L hentitra PCB

Hard PCBS dia ireo izay vita amin’ny fitaovana matevina ary tsy azo fehezina. Ny sasany amin’ireo tombony lehibe omeny:

Ireto PCBS ireto dia mifintina, miantoka ny famoronana karazana faribolana sarotra manodidina azy ireo.

Hard PCBS are easy to repair and maintain because all components are clearly marked. Ankoatr’izay, voalamina tsara ny lalan’ny signal.

L malefaka PCB

PCB malefaka dia miorina amin’ny fitaovana mora miorina. These PCBS are available in single-sided, double-sided and multi-layer formats. Manampy amin’ny fampihenana ny fahasarotana ao anatin’ny singa fitaovana io. Some of the advantages these PCBS offer are:

Ireo PCBS ireo dia manampy amin’ny fitehirizana toerana be sy mampihena ny lanjan’ny tabilao.

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

Ireo PCBS ireo dia natao ho an’ny toe-java-miasa izay heverina ny mari-pana sy ny hakitroka.

L hentitra – malefaka -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. Vokatr’izany dia ampiasaina amin’ny fampiharana medikaly sy miaramila isan-karazany izy io.

Ireo PCBS ireo dia maivana, mitahiry hatramin’ny 60% ny lanjany sy ny habaka.

L PCB matetika matetika

Hf PCBS are used in the frequency range of 500MHz to 2GHz. Ireo PCBS ireo dia azo ampiasaina amina karazana fampiharana matetika matetika, toy ny rafi-pifandraisana, PCBS mikraoba, PCBS microstrip, sns.

L Aluminium lamosina PCB

Ireo takelaka ireo dia ampiasaina amin’ny fampiharana mahery vaika satria ny firafitry ny aliminioma dia manampy amin’ny fanaparitahana ny hafanana. Ny PCBS tohanan’ny aliminioma dia fantatra fa manana hakingana avo lenta ary faran’izay kely ny expansibility hafanana, mahatonga azy ireo ho tsara ho an’ny fampiharana manana fandeferana mekanika avo lenta. PCB dia ampiasaina amin’ny LED sy ny famatsiana herinaratra.

Ny fangatahana PCBS dia mahatratra indostrialy rehetra. Androany dia hahita mpamokatra PCB malaza sy mpaninjara malaza afaka mahafeno ny filan’ny tsenan’ny fitaovana mifandraika amin’ny fifaninanana ianao. It is always recommended to purchase PCBS for industrial and commercial use from reputable manufacturers and suppliers.
