Karazana boards isan-karazany

The pirinty boribory pirinty na PCB no birao fanohanana ara-batana raha mampifandray ireo singa elektronika isan-karazany amin’ny rafitra midadasika kokoa. Ny board circuit dia mampiasa wiring conductive, padding ary zavatra hafa izay manako avy amin’ny sosona varahina.

Iray lafiny

Araka ny soso-kevitry ny anarana, ny PCB tokana dia vita amin’ny fitaovana tokana, fantatra ihany koa amin’ny hoe “substraté”. On top of the base is a thin foil layer made of copper. Izany dia miasa ho toy ny conducteur famantarana elektrika.

Ireo no karazana PCBS mahazatra indrindra ary malaza amin’ny famokarana boky noho ny vidiny ambany. Ireo takelaka ireo dia hita matetika amin’ny fakantsary, kajy ary fitaovana radio.

Hita amin’ny endrika kilalao tsotra koa izy ireo.

Lafiny roa

Miasa mitovy amin’ny solaitrabe vita pirinty vita pirinty roa sosona ny biraon’ny faritra vita pirinty, saingy mipetaka eo anelanelan’ny sosona conductive amin’ny lafiny roa. 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.

Ny PCBS misy sisiny roa dia matetika hita amin’ny finday, milina mpivarotra, mpanara-maso fiara ary fitaovana metatra herinaratra.

Multilayer

Ny endrika dia misy lafiny roa ary mivelatra eo amboniny. Ny multilayer dia fitambarana PCBS roa sosona tsy latsaky ny telo (3). Mandray ny teknolojia napetraka eto izy ireo ary mampitombo ny fahaizany mamokatra.

Ny habeny sy ny habaka no tombony lehibe indrindra amin’ny PCBS marobe. Afaka mampiasa board multilayer izy ireo fa tsy boards maromaro.

Izy ireo dia ampahany manan-danja amin’ny fizaran-tany haingam-pandeha satria ny haben’ny board dia mamela ny fametrahana sy ny herin’ny conducteur mety.

mafy fo

Rigid PCBS can be single, double, or multi-layered. Ny rigidity dia manondro ny fitaovana substrate izay nanaovana ny boards. 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. Izy ireo dia natao ho mateza ary azo ampiasaina amin’ny toerana tokana sy endrika.

Rigid PCBS benefit from ease of maintenance and ease of use. Ny tetikasa rehetra dia manana toerana ary voamarika mazava tsara rehefa natao. Tsy voafetra amin’ny endrika iray izy ireo ary mety manomboka amin’ny sosona tokana ka hatramin’ny endrika PCB folo (10).

malefaka

Flexible PCBS miasa amin’ny fomba mitovy amin’ny PCBS henjana, fa vita amin’ny fitaovana samy hafa.

Ny takelaka henjana dia vita amin’ny akora mateza (midika hoe mitazona ny endriny) (matetika fangaro vita amin’ny fiberglass), raha plastika na fitaovana mitovitovy amin’izany kosa ny takelaka flexible.

Ny fahaiza-manao ara-bakiteny no tombony lehibe indrindra amin’ny PCBS mora vidy. Azo atao ny mitsitsy ny vidiny noho ny fahafahan’izy ireo “manarona” ireo faritra izay mety tsy maintsy handehanan’ny takelaka henjana.

The main applications of flexible PCBS are in systems that may cause damage to the environment. Ny famolavolana azy ireo dia mahatonga azy ireo ho mahatohitra kokoa ny mari-pana, ny rano, ny harafesina ary ireo singa hafa izay mety hanimba ireo takelaka henjana.

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.

Tafiditra ao anatin’izany ny andiana rindran-damina mora azo mifandray amin’ny takelaka henjana maromaro. Manamora kokoa ny famolavolana izany, satria manambatra ny singa rehetra ilaina amin’ireo ampahany ireo ho ampahany “tokana”.

Ny henjana sy ny flexibilité dia azo jerena amin’ny fampiharana ara-pitsaboana.

Aluminum miverina

Ny fanaparitahana hafanana dia ivon’ny PCB. Raha ny mari-pana rafitra dia heverina, mampiasa aluminium backboard PCB no safidy tsara indrindra, izay ahitana tombontsoa hafa miharihary.

Ny firafitry ny PCB dia mitovy amin’ny fenitra tokana na roa sosona, fa ny fitaovana ampiasaina dia miovaova.

Izy ireo dia mateza kokoa ary tena tia ny tontolo iainana. Aluminum dia tsy misy poizina ary tena mora ny manodina. On top of that, it’s incredibly cheap, it’s one of the cheapest metals in mining, and it’s cheap to make.

Hafa miampy avo

Hf PCBS dia tsy naorina amin’ny fomba vaovao, ohatra, mampitaha tokana amin’ny sosona maro, fa manondro karazana fampiasana. Ny PCBS avo lenta dia azo ampiasaina rehefa mila ampitaina amin’ny tahan’ny mihoatra ny 1GHz ny famantarana. They are mainly used in large communication systems.

Ny tombony amin’ny fampiasana PCB

Na dia manana tombony aza ny karazana board tsirairay, dia misy tombony maro amin’ny fampiasana PCB amin’ny ankapobeny.

Easy trouble shooting and maintenance

Ny fandrindrana, na ny “trace”, amin’ny solaitrabe dia manamora ny famantarana ireo fitaovana misy olana sy manolo azy

Remove and reattach to board

Ny fahombiazan’ny: Tsy ilaina ny manangana ny faritra manontolo rehefa manamboatra na manova

Drafitra efa vita ny biraon’ny fizaran-tany ary kely kokoa ny fotoana hanaovana azy noho ny fizaran-tany mahazatra

Tabataba ambany: Ny famolavolana PCB natao tsara dia mety hitarika amin’ny singa elektrika ambany taratra, fantatra amin’ny anarana hoe “cross talk.”

Manampy amin’ny fanafoanana ny tabataba elektronika izay mety hanimba ny fahombiazan’ny fitaovana

azo itokisana: Noho izany, ny fifandraisana amin’ny birao dia voapetaka amin’ny tariby varahina. Tsy misy fifandraisana mivaha na “tariby mihozongozona.”

Ny welding dia mampifandray ny singa rehetra amin’ny solaitrabe, ka miasa izy ireo na dia mihetsika aza ny board.
