Igice: ibintu bitandukanye bigira ingaruka kubiciro byubuyobozi bwa PCB
Igiciro cya PCB yamye ari urujijo kubaguzi benshi, kandi abantu benshi bazokwibaza uburyo ibi biciro bibarwa mugihe utanze ibicuruzwa kumurongo.Reka tuganire kubice bigize igiciro cya PCB hamwe.
- Ibikoresho bitandukanye bikoreshwa muri PCB biganisha kubiciro bitandukanye
Kurugero, Ikibaho gisanzwe, isahani muri rusange ifite FR4 (Sheng yi, Kingboard, Guoji, ibiciro bitatu kuva hejuru kugeza hasi), uburebure bwa plaque kuva kuri mm 0.2 kugeza kuri mm 3.0, uburebure bwumuringa kuva 0.5 oz kugeza 3 oz, ibi byose muri ibikoresho by'isahani ku giciro kinini;Muri wino yo kurwanya, amavuta asanzwe ya thermosetting hamwe namavuta yicyatsi kibisi nayo ibaho itandukaniro ryibiciro.
2.Uburyo butandukanye bwo kuvura hejuru buganisha kubiciro bitandukanye
Uburyo busanzwe bwo kuvura hejuru: OSP (anti-okiside irwanya), hariho HASL, HASL idafite isuku (ibidukikije), isahani ya zahabu, Zahabu ya Immersion hamwe nuburyo bumwe bwo guhuza, nibindi, igiciro cyibikorwa bihenze cyane mugihe kizaza.
3.PCB ubwayo yatewe ningorane zitandukanye zo gutandukana kwibiciro.
Hano hari imyobo 1000 mubibaho byombi.Niba ingano yumwobo wikibaho kimwe irenze 0.2mm, ubunini bwurwo rundi rubaho ruri munsi ya 0.2mm.Niba ubwoko bubiri bwumuzunguruko ari bumwe, ariko ubugari bwumurongo numurongo utandukanijwe, kimwe kinini kuruta 4mil ikindi kikaba gito kuri 4mil, bizanatera ibiciro bitandukanye byumusaruro.Ibikurikira uracyafite bike ntibagendeye kubishushanyo mbonera byubukorikori busanzwe nabwo ni ukongeramo amafaranga, urugero igice cyumwobo, gushyingura umwobo uhumye, umwobo wibyombo, kanda isahani yingenzi kugirango ucapishe amavuta ya karubone.
