—Ihlelwe yi-JDB PCB COMPNAY.

Onjiniyela be-PCB bavame ukuhlangana nezinkinga ezihlukahlukene zokugunyazwa kokuphepha lapho benza umklamo we-PCB.Ngokujwayelekile lezi zidingo zokuhlukanisa izikhala zihlukaniswa izigaba ezimbili, esokugunyazwa kokuphepha kukagesi, kanti esinye esokugunyazwa kokuphepha okungezona izinto zikagesi.Ngakho-ke, yiziphi izidingo zesikhala zokuklama amabhodi esekethe e-PCB?

1. Ibanga lokuphepha likagesi

1. Isikhala phakathi kwezintambo: isikhala esincane somugqa siphinde sibe umugqa nomugqa, futhi isikhala somugqa nephedi akumele sibe ngaphansi kuka-4MIL.Ngokombono wokukhiqiza, yebo, inkulu iba ngcono uma kungenzeka.I-10MIL evamile ivame kakhulu.

2. Imbobo yephedi kanye nobubanzi bephedi: Ngokomkhiqizi we-PCB, uma indawo yokuvula iphedi ibholwa ngomshini, ubuncane akumele bube ngaphansi kuka-0.2mm;uma kusetshenziswa i-laser drilling, ubuncane akumele bube ngaphansi kuka-4mil.Ukubekezelelana kwembobo kuhluke kancane kuye ngokuthi ipuleti, ngokuvamile ingalawulwa ngaphakathi kwe-0.05mm;ububanzi obuncane bomhlaba akumele bube ngaphansi kuka-0.2mm.

3. Ibanga phakathi kwephedi nephedi: Ngokusho komthamo wokucubungula womkhiqizi we-PCB, ibanga akufanele libe ngaphansi kuka-0.2MM.

4. Ibanga phakathi kweshidi lethusi kanye nonqenqema lwebhodi: okungcono kungabi ngaphansi kuka-0.3mm.Uma kuyindawo enkulu yethusi, ngokuvamile kuba nebanga elihoxisiwe ukusuka onqenqemeni lwebhodi, ngokuvamile lisethwa ku-20mil.

2. Ibanga lokuphepha elingelona ugesi

1. Ububanzi, ubude nesikhala sezinhlamvu: Izinhlamvu kusikrini sikasilika ngokuvamile zisebenzisa amanani avamile afana no-5/30, 6/36 MIL, njll. Ngoba uma umbhalo umncane kakhulu, ukuphrinta okucutshunguliwe kuzofiphaliswa.

2. Ibanga ukusuka kusikrini sikasilika ukuya kuphedi: isikrini sikasilika asivunyelwe ukuba sibe phezu kwephedi.Ngoba uma isikrini sikasilika simbozwe ngephedi, isikrini sikasilika ngeke sifakwe ithini uma sithayina, okuzothinta ukubekwa kwengxenye.Ngokuvamile kudingeka ukuthi ugcine isikhala esingu-8mil.Uma indawo yamanye amabhodi e-PCB iseduze kakhulu, ukuhlukaniswa kwe-4MIL nakho kuyamukeleka.Uma isikrini sikasilika sivala ngephutha iphedi ngesikhathi sokuklanywa, ingxenye yesikrini sikasilika esishiywe kuphedi izokhishwa ngokuzenzakalelayo ngesikhathi sokukhiqiza ukuze kuqinisekiswe ukuthi iphedi ifakwe ithina.

3. Ubude be-3D nesikhala esivundlile esakhiweni sokusebenza: Lapho ukhweza izingxenye ku-PCB, cabanga ukuthi ingabe isiqondiso esivundlile kanye nobude besikhala kuzongqubuzana nezinye izakhiwo zemishini.Ngakho-ke, lapho uklama, kuyadingeka ukucabangela ngokugcwele ukuguquguquka kwesakhiwo sesikhala phakathi kwezingxenye, naphakathi kwe-PCB eqediwe negobolondo lomkhiqizo, futhi ugcine ibanga eliphephile lento ngayinye eqondiwe.

Okungenhla ngezinye zezidingo zesikhala okudingeka kuhlangatshezwane nazo lapho uklama amabhodi esekethe e-PCB.Uyazi konke?
