Iyo V-yekukora nzira yakashandiswa kwemakore mazhinji mukugadzirwa kwe yakadhindwa redunhu bhodhi (Pcb). Iine pcb yekugadzira tekinoroji ichichinja nekukurumidza, zvakakosha kuti uzive yazvino pcb yekukora nhungamiro yekutevera uye kuti ingasiyana sei nezvawakamboshandisa kare.

Kuitisa zvibodzwa kunosanganisira mashizha maviri anotenderera pamwe chete kunongedzera-ku-poindi sezvo pcb inofamba pakati pemapanga. Maitiro acho anenge akafanana nekucheka pizza mupancake, uchicheka iyo pizza kuita zvidimbu zvidete uye nekukurumidza kuendesa chigadzirwa kudanho rinotevera, iro rinogona kuvandudza kugadzirwa kwese. Saka iwe unofanirwa kushandisa rinhi kurova pane yako PCB? Ndezvipi zvingangokanganisa izvi?

Square yakadhindwa redunhu bhodhi

Kunyangwe yako pcb yakaenzana kana yakatetepa, mativi ese ane mitsara yakatwasuka uye inogona kutemwa pane V-notch muchina. Mubvunzo wekubvunza ndewekuti, wakakodzera here kuti utore, kana pane dzimwe nzvimbo dzinoda kugadziriswa? Kukora kana kusahwina? Heano zvikonzero zvishoma zvekuramba kupindura.

Chikamu chakatetepa PCBS

Akadhindwa wedunhu mabhodhi akaonda kupfuura 0.040 inches akaomarara notch nekuda kwezvikonzero zvakati. Chishoma pa0.012 “chinodiwa kuchengetedza iyo V-yakaumbwa coil, sezvo zvinhu (coil) notch blade kuruboshwe zvakagadzirirwa panguva imwe chete notch 0.010” – kudzika kwe0.012 “pamativi ese maviri ichaita iyo 0.020″ +/- 0.004 ” mambure madiki pane 0.040 ”.

Mutete akadhindwa wedunhu mabhodhi ane kumwe kuchinjika mune izvo chete zvinhu. Flexible PCBS uchishandisa iyo notched mabhureki nzira inogona kusiya yakashata micheto uye yakaturika tambo. Kudzora kuitisa zvibodzwa nezvinhu zvakapfava uye kubvumira kukanganisa kwakanyanya kunonyanya kuoma. Iyo banga yakakosha kumamiriro ekushivirira ehupamhi hwechinyorwa kubva kumusoro kusvika pasi, uye kune tambo yakatwasuka yekururamisa kuona kuti hupamhi hwezvinhu hauputse panguva yegungano. Kana kudzika kwechinyorwa kusingaenzanisike pakati pekuruboshwe nekurudyi, chikamu chinenge chakanyanya kunetsa kutyora, zvichisiya tambo uye zvinogona kutsemuka pamipendero.

Iyo PCB mune irongwa yakawanikwa

Kunyanya kunyora kunoiswa, iyo isina kusimba mapaneru anogona kuve, zvichikonzera kubata kusimba, dzakakanganiswa arrays uye / kana matambudziko egungano.

Zvikamu zvine zviyero zvidiki

Iyo diki iyo square inch yebhodhi, zvakanyanya kuomarara. Kana saizi yePBB iri diki, mabhodhi ari mukobvu kupfuura 0.062 “zvinonetsa kupatsanura. Isingasviki 1 inch mune chero divi ingangoda mamwe maturusi ekuparadzanisa zvikamu.

Shingairira iyo PCB iyo yakareba kwazvo

Akadhindwa wedunhu mabhodhi ane akareba X kana Y (gumi nemaviri inches kana kupfuura) anogona kunge asina kusimba uye nyore kuputswa kana akakwenenzverwa zvakadzama. Kuwedzera zvinorema zvinhu kune yakatove isina kusimba safu kunogona kukonzera mapaneru kutyora panguva yekubata, kuungana, kana kunyangwe kutakurwa. Kuteedzera kusvetuka mamaki kana tabular nzira ingave iri nani sarudzo.

Kugovera ndiro

Kana iwe uri kubatira PCBS yakakura kupfuura 0.096 inches kukora, shandisa iyo imwechete scheme, aine maviri mashizha achicheka zvakadzika mukati me laminate pamusoro, ichisiya mambure 0.020 inches +/- 0.004 inches. Pamusoro peiyi ukobvu, zvinonetsa kupaza, nekuti kukombama hakuna kukwana. Makobvu akakora anogona kushandisa nzira iyi kumabhodhi akanyanya, asi dzimwe nguva zvinogona kutungamira kumatambudziko nemhangura kumucheto spacing.

Chishandiso chekupomba

Kune zvishandiso zviripo zvekubatsira mukudzora PCBS. Nekudaro, iyo inofanirwa kushandiswa nemazvo uye kuongororwa kuti inyatsoita kudzivirira kukuvara kwemupendero, kutyoka kana kukwenya kwepasi. Kuwedzera kubata kwePCBS yakazara yakaungana zvine njodzi nguva dzose.

Wedzera Angle kana redhiyo kuchikamu

Izvi zvinotadzisa kugona kushandisa nzira yekumaka here?

Kwete, asi iwe uchiri kuda mativi akapetana kuti utange bhodhi. Kazhinji, kana uchishandisa iyo notching nzira, iyo PCBS inozomira pamwe chete. Anocheka anotema zvese kumusoro uye pasi.

Kuti usvibise nemakona kana radii, unofanirwa kusiya nzvimbo pakati pePCBS. Iyo yakajairika Router inoronga inoshandisa 0.096 “yekugaya cutter iyo inoda kanenge 0.100” kuchenesa kukuya pakati pezvikamu. Kune zvakare marara mashoma pakati pezvikamu. Hazvikurudzirwi kushandisa 0.100 “nzira dzekusiyanisa uye dzekucheka pakati pemabhodhi, kunyangwe zviine maturusi, zvinonetsa kuputsa. Kana nzvimbo ichidikanwa, zvinokurudzirwa kushandisa 0.200 “kana yakakura nzvimbo yemapipi.

Pcb dhizaini dhizaini yevagadziri

Pindura mubvunzo wakajairwa; Ehe, iwe unogona giredhi ingangoita chero yakadhindwa wedunhu bhodhi ine yakatwasuka pamupendero, asi iwe ungangoda kushandisa musanganiswa wekurovera uye wiring.

Iyo yakakwira tembiricha laminated zvinhu ine yakakwira kupfuura 150TG ine yakaomesesa zvinhu uye microstructure. Usashandise akaenzana zvidimbu zvidimbu zvinoshandiswa mu130tg zvinhu zvakajairwa. Zvikamu zvakadzama zvinodikanwa kuti utyore nyore nyore chinhu chakasimba chakarukwa. Kune yakakwira tembiricha zvinhu, shandisa 0.015 “+/- 0.004” mesh.

Kubva pamucheto simbi, iyo yekudzivirira dura inofanirwa kuve inoenderana nehupamhi hweakadhindwa wedunhu bhodhi. Kana yakaenzana kana kuti isingasviki 0.062 “, nhambwe iri pakati pesimbi nemucheto chaiwo weplate inenge iri 0.015“. Iyi yakanaka nhamba yekureva. Makobvu akaomesesa anogona kushandiswa 0.096 “kana 0.125” kumusoro uye 0.020 “kana kumusoro kana nzvimbo ichibvumidza mabasa ese kubva kumucheto kwekadhi.

Kune akadhindwa wedunhu mabhodhi asingasviki 0.040 “muukobvu, gara uchironga kushandisa chete makumbo kune wiring kudzivirira chero matambudziko.
