Izidingo zesikhala ekuklameni pcb

  Ibanga lokuphepha likagesi

 

1. Isikhala phakathi kwezintambo
Ngokomthamo wokukhiqiza wabakhiqizi be-PCB, ibanga eliphakathi kokulandelelwa nokulandelelwa akufanele libe ngaphansi kuka-4 mil. Isikhala esincane somugqa siphinde sibe sikhala phakathi komugqa uye kumugqa kanye nesikhala somugqa kuya kuphedi. Hhayi-ke, ngokombono wethu wokukhiqiza, yiqiniso, inkulu iba ngcono ngaphansi kwezimo. I-general 10 mil ivame kakhulu.

2. Indawo yephedi nobubanzi bephedi:
Ngokomkhiqizi we-PCB, ubuncane bembobo yobubanzi bephedi abukho ngaphansi kuka-0.2 mm uma ibholwa ngomshini, futhi abukho ngaphansi kuka-4 mil uma ibholwa nge-laser. Ukubekezelela imbobo kuhluke kancane kuye ngokuthi ipuleti. Ngokuvamile ingalawulwa ngaphakathi kuka-0.05 mm. Ububanzi obuncane bephedi akufanele bube ngaphansi kuka-0.2 mm.

3. Ibanga phakathi kwephedi nephedi:
Ngokwamakhono okucubungula abakhiqizi be-PCB, ibanga phakathi kwamaphedi namaphedi akufanele libe ngaphansi kuka-0.2 mm.

 

4. Ibanga phakathi kwesikhumba sethusi nomphetho webhodi:
Ibanga phakathi kwesikhumba sethusi esikhokhisiwe kanye nomphetho webhodi le-PCB kungcono lingabi ngaphansi kuka-0.3 mm. Uma ithusi libekwe endaweni enkulu, ngokuvamile kudingekile ukuba kube nebanga lokuncipha ukusuka emaphethelweni ebhodi, ngokuvamile elibekwe ku-20 mil. Ngokuvamile, ngenxa yokucatshangelwa komshini kwebhodi lesifunda eliqediwe, noma ukugwema ukuba nokwenzeka kokugoqeka noma ukujikeleza okufushane kukagesi okubangelwa umucu wethusi oveziwe onqenqemeni lwebhodi, onjiniyela bavame ukushwabana amabhulokhi ethusi endawo enkulu ngo-20 mil ngokuqhathaniswa emaphethelweni ebhodi. Isikhumba sethusi asihlali sisakazwa emaphethelweni ebhodi. Kunezindlela eziningi zokubhekana nalokhu kuncipha kwethusi. Isibonelo, dweba isendlalelo sokugcina onqenqemeni lwebhodi, bese usetha ibanga phakathi kwethusi ne-keepout.

Ibanga lokuphepha elingelona ugesi

 

1. Ububanzi bezinhlamvu nobude nesikhala:
Ngokuphathelene nezinhlamvu zesikrini sikasilika, ngokuvamile sisebenzisa amanani avamile afana no-5/30 6/36 MIL, njll. Ngoba uma umbhalo umncane kakhulu, ukucubungula nokuphrinta kuzofiphaliswa.

2. Ibanga ukusuka kusikrini sikasilika ukuya kuphedi:
Ukuphrinta isikrini akuvumeli amaphedi. Uma isikrini sikasilika simbozwe ngamaphedi, ithini ngeke ifakwe uma i-soldering, okuzothinta ukubekwa kwezingxenye. Abakhiqizi bebhodi elijwayelekile badinga isikhala esingu-8 mil ukuthi sigcinwe. Uma kungenxa yokuthi indawo yamanye amabhodi e-PCB iseduze kakhulu, ukuhlukaniswa kwe-4MIL akwamukeleki neze. Khona-ke, uma isikrini sikasilika sivala ngephutha iphedi ngesikhathi sokuklama, umenzi webhodi uzosusa ngokuzenzakalelayo ingxenye yesikrini sikasilika esishiywe kuphedi ngesikhathi sokukhiqiza ukuze aqinisekise ithini kuphedi. Ngakho kudingeka sinake.

3. Ubude be-3D nesikhala esivundlile esakhiweni sikamshini:
Lapho ukhweza amadivayisi ku-PCB, kuyadingeka ukuthi ucabangele ukuthi isiqondiso esivundlile nobude besikhala kuzongqubuzana yini nezinye izakhiwo zemishini. Ngakho-ke, lapho uklama, kuyadingeka ukucabangela ngokugcwele ukuguquguquka kwesakhiwo sendawo phakathi kwezingxenye, kanye naphakathi komkhiqizo we-PCB negobolondo lomkhiqizo, futhi ugcine ibanga eliphephile lento ngayinye eqondiwe.
