Inxalenye: izinto ezahlukeneyo ezichaphazela ixabiso ibhodi PCB
Ixabiso lePCB belisoloko liyipuzzle kubathengi abaninzi, kwaye abantu abaninzi baya kuzibuza ukuba la maxabiso abalwa njani xa ubeka iiodolo kwi-Intanethi. Makhe sithethe malunga amacandelo PCB ixabiso kunye.
- Izinto ezahlukeneyo ezisetyenziswa kwi-PCB zikhokelela kumaxabiso ahlukeneyo
Ngokomzekelo, ipaneli ephindwe kabini, ipleyiti ngokubanzi ine-FR4 (Sheng yi, Kingboard, Guoji, amaxabiso amathathu ukusuka phezulu ukuya ezantsi), ubukhulu bepleyiti ukusuka kwi-0.2 mm ukuya kwi-3.0 mm, ubukhulu bobhedu ukusuka kwi-0.5 oz ukuya kwi-3 oz, zonke ezi zingaphakathi. izinto zepleyiti kumahluko omkhulu wexabiso; Kwi-inki yokumelana, i-oyile ye-thermosetting eqhelekileyo kunye ne-oyile eluhlaza ye-photosensitive ikhona umahluko wexabiso elithile.
2.Iinkqubo ezahlukeneyo zonyango lomphezulu zikhokelela kumaxabiso ahlukeneyo
Inkqubo yonyango yendawo eqhelekileyo: i-OSP (ukumelana ne-oxidation), kukho i-HASL, i-HASL ye-Lead-free (indalo), i-plating yegolide, igolide yokuntywila kunye nenkqubo ethile yokudibanisa, njalo njalo, ixabiso lenkqubo libiza kakhulu kwixesha elizayo.
I-3.PCB ngokwayo ibangelwa ubunzima obuhlukeneyo bokuhluka kwamaxabiso.
Kukho imingxuma eyi-1000 kuzo zombini iibhodi zeesekethe. Ukuba ubungakanani bomngxuma webhodi enye bukhulu kune-0.2mm, ubungakanani bomngxuma wenye ibhodi bungaphantsi kwe-0.2mm. Ukuba iindidi ezimbini zeebhodi zeesekethe ziyafana, kodwa ububanzi bomgca kunye nezithuba zomgca zahlukile, enye inkulu kune-4mil kwaye enye incinci kune-4mil, iya kubangela iindleko ezahlukeneyo zokuvelisa. Okulandelayo kusekho abambalwa abahambi uyilo lokuhamba kweplate yobugcisa eqhelekileyo kukongeza imali eqokelelweyo, umzekelo umngxuma oyisiqingatha, ukungcwaba umngxuma oyimfama, umngxuma wesitya, cofa ipleyiti yesitshixo ukuprinta ioyile yekhabhoni.
