Misavoritaka matetika ireo vao terakaPCB schematic” with “PCB design document” when talking about printed circuit boards, but they actually mean different things. Ny fahafantarana ny fahasamihafana misy eo amin’izy ireo no lakilen’ny famokarana PCB mahomby, noho izany ity lahatsoratra ity dia handrava ny fahasamihafana lehibe eo amin’ny skema PCB sy ny famolavolana PCB ho an’ireo vao manomboka mahomby kokoa.

Alohan’ny hidirana amin’ny fahasamihafana misy eo amin’ny skema sy ny famolavolana, zava-dehibe ny fantatra, inona ny PCB? Inside electronic equipment, there are printed circuit boards, also known as printed circuit boards. The green circuit board, made of precious metal, connects all the electrical components of the device and enables it to function properly. Tsy mandeha ny elektronika raha tsy PCBS.

Kisary skatika PCB sy endrika PCB

Ny skotisma PCB dia endrika boribory roa misy habe roa izay mampiseho ny fiasa sy ny fifandraisana eo amin’ireo singa samihafa. Ny famolavolana PCB dia endrika telo-habe, mba hiantohana ny fiasan’ny fizaran-tany aorian’ny fanamarihana ny toerana misy ireo singa.

Therefore, PCB schematic is the first part of the design of printed circuit board. Ity dia sary an-tsary, na an-tsoratra na angona, izay mampiasa marika nifanarahana mba hamaritana ireo fifandraisana amin’ny faritra. Manondro ireo singa hampiasaina sy ny fomba fampiasana tariby koa izy io.

As the name implies, a PCB schematic is a plan, a blueprint. Tsy mamaritra ny toerana hametrahana ireo singa ireo. Fa kosa, ny skemaika dia manoritra ny fomba hahitan’ny PCB ny fifandraisana amin’ny farany ary mamorona ampahany lehibe amin’ny fizotran’ny drafitra.

Raha vantany vao vita ny blueprints dia manaraka ny famolavolana PCB. Design is the layout or physical representation of the PCB schematic, including copper wiring and hole layout. Ny famolavolana PCB dia mampiseho ny toerana misy ireo singa sy ny fifandraisany amin’ny varahina.

PCB design is a performance-related phase. Ny injeniera dia nanangana singa tena izy teo ambonin’ireo endrika PCB, namela azy ireo hitsapa raha mandeha tsara ny fitaovana. Araka ny voalaza tetsy aloha, tokony hisy olona afaka mahatakatra ny tetika PCB, saingy tsy mora ny mahatakatra ny fampiasa azy amin’ny fijerena ilay prototype.

Both phases are complete, and once you are satisfied with the PCB’s performance, you need to implement them through the manufacturer.

Singa skematika PCB

Ankehitriny rehefa fantatsika ny fahasamihafana misy eo amin’izy roa, andao hojerentsika akaiky ireo singa ao amin’ny skema PCB. Araka ny efa nolazainay, ny fifandraisana rehetra dia hita maso, saingy misy fampandrenesana vitsivitsy tsy maintsy adino:

In order to see the connections clearly, they are not created to scale; Amin’ny famolavolana PCB, afaka mifanakaiky izy ireo

Ny fifandraisana sasany dia mety hiampita, izay tsy azo atao mihitsy

Ny fifandraisana sasany dia mety amin’ny lafiny mifanohitra amin’ny layout, miaraka amin’ny marika manondro fa mifandray izy ireo

Ity “blueprint” PCB ity dia mety ho pejy, pejy roa, na pejy maromaro milazalaza izay rehetra tokony hampidirina ao anaty endrika

Ny teboka farany tokony homarihina dia ny skematika sarotra kokoa dia azo atambatra amin’ny alàlan’ny asany hanatsarana ny famakiana. Arranging connections in this way does not occur at the next stage, and the schematic usually does not match the final design of the 3D model.

Element Element Design PCB

Fotoana izao hijerena akaiky ireo singa ao amin’ilay rakitra famolavolana PCB. Amin’ity dingana ity dia mifindra amin’ny blueprints voasoratra isika amin’ny fisehoana ara-batana namboarina tamin’ny fampiasana lamina na akora vita amin’ny seramika. PCBS malefaka dia ampiasaina amin’ny fampiharana sarotra kokoa izay ilana toerana malalaka fanampiny.

Ny atin’ny antontan-taratasy famolavolana PCB dia manaraka ny drafitra napetrak’ilay fizotry ny skema, saingy, araka ny voalaza tetsy aloha, dia samy hafa be izy roa. Efa niresaka momba ny tetika PCB isika, saingy inona ny fahasamihafana azo jerena ao amin’ny antontan-taratasy famolavolana?

Rehefa miresaka momba ny antontan-taratasy famolavolana PCB isika dia miresaka momba ny maodely 3D izay misy ny tabilao vita pirinty sy ny antontan-taratasy famolavolana. Izy ireo dia mety ho tokan-tena na maromaro sosona, na dia sosona roa aza no be mpitranga indrindra. Azontsika atao ny mijery ny fahasamihafana misy eo amin’ny skema PCB sy ny antontan-taratasy famolavolana PCB:

Ny singa rehetra dia refesina tsara ary apetraka

Raha teboka roa tsy tokony ampifandraisina dia tsy maintsy afindra na mifindra amin’ny sosona PCB hafa izy ireo mba hisorohana ny fiampitana amin’ny sosona iray ihany

Ho fanampin’izay, araka ny niresahana fohifohy, ny famolavolana PCB dia miahiahy bebe kokoa amin’ny tena fahombiazana, satria io dia somary misy ny dingana fanamarinana ny vokatra farany. Amin’izay fotoana izay, ny maha-azo ampiharina ny tena asan’ny endrika dia tsy maintsy apetraka, ary ny fepetra ara-batana amin’ny tabilao misy pirinty dia tsy maintsy dinihina. Ny sasany amin’izany dia:

How is the spacing of the components allowed for adequate heat distribution

Misy mpampitohy manodidina ny sisiny

Raha ny toetr’andro sy ny hafanana, tsy maintsy matevina ireo soritra isan-karazany

Satria ny fetra ara-batana sy ny takiana dia midika fa ny antontan-taratasy famolavolana PCB matetika dia samy hafa be amin’ny famolavolana ny skotozy, ny antontan-taratasy famolavolana dia misy sosona fanontana silkscreen. Ny sosona fanontana amin’ny efijery dia manondro litera, isa ary marika hanampiana ireo injeniera hivory sy hampiasa ny solaitrabe.

It is required that all components work as planned after being assembled onto the printed circuit board. Raha tsy izany dia mila havaozina.

famaranana

Na dia mikorontan-tsaina matetika aza ny antontan-taratasin’ny PCB sy ny famolavolana PCB, ny fanaovana skema PCB sy ny endrika PCB dia manondro fizarana roa samy hafa rehefa mamorona tabilao vita pirinty. PCB design, which is an important part of PCB performance and integrity, must be made prior to the creation of a PCB schematic diagram that can draw the process flow.
