Uninzi lwabathengi bemifanekiso ye-elektroniki badidekile malunga nexabiso le-PCBS. Kwanabanye abantu abaneminyaka emininzi bamava okuthengwa kwe-PCB abanakuqonda ngokupheleleyo isizathu sokuqala. Ngapha koko, ixabiso le-PCB lidityaniswe kwezi zinto zilandelayo:
Okokuqala, amaxabiso ahlukile ngenxa yezixhobo ezahlukeneyo ezisetyenziswa kwi-PCB.
Ukuthatha i-PCB eqhelekileyo ye-PCB njengomzekelo ovela kwi-Fr-4, CEM-3, njl njl nge-0.2mm ukuya kwi-3.6mm. Ubunzima bobhedu luyahluka ukusuka kwi-0.5Oz ukuya kwi-6oz, yonke into ebangele umahluko omkhulu wamaxabiso. Amaxabiso e-Serdermak i-IK kwahlukile kwizixhobo eziqhelekileyo ze-inki kunye ne-Inki ye-inki eluhlaza.
Okwesibini, amaxabiso ahlukile ngenxa yeenkqubo ezahlukeneyo zemveliso.
Inkqubo eyahlukileyo yemveliso ikhokelela kwiindleko ezahlukeneyo. Enje ngeBhodi ePhakathisiweyo yeGolide kunye neBhodi ye-tin, imilo yokutsala kunye nokuhluthwa, ukusetyenziswa kwe-screen ye-screen kunye nemigca yefilimu yefilimu kuya kwenza iindleko ezahlukeneyo, okukhokelela kwixabiso lokwahluka.
Okwesithathu, amaxabiso ahlukile ngenxa yobunzima kunye noxinano.
I-PCB iya kuba yindleko eyahlukileyo nokuba izixhobo kunye nenkqubo ziyafana, kodwa zinobunzima obuqhelekileyo kunye noxinano. Umzekelo, ukuba kukho imingxunya eyi-1000 kuzo zombini iibhodi zesekethe, ububanzi be-hole yebhodi inkulu kune-0.6mm kunye ne-hole kunye ne-hole idayitile yenye iBhodi ingaphantsi kwe-0.6mm, eya kuthi iyenza iindleko zokuntywila. Ukuba iibhodi zesekethe ezimbini zilingafani kwezinye izicelo, kodwa ububanzi bomgca buye bahlukile kwiindleko ezahlukeneyo, ezinjengobubanzi beBhodi enye inkulu kune-0.2mm, ngelixa enye ingaphantsi kwe-0.2mmm. Ngenxa yokuba iibhodi zeBards zingaphantsi kwe-0.2mm ineqondo elinesiphene eliphakamileyo, oko kuthetha ukuba iindleko zemveliso ziphezulu kunesiqhelo.
Okwesine, amaxabiso ahlukile ngenxa yeemfuno ezahlukeneyo zabathengi.
Iimfuneko zabathengi ziya kuchaphazela ngqo ireyithi engeyosifo kwimveliso. Njengeekorithi enye yebhodi kwi-IPC-A-600E ifuna i-98% yereyithi yokupasa, ngelixa inikezelwe kwicandelo le-90% kuphela efuna kuphela ireyithi yokupasa i-90%, ibangela iindleko ezahlukileyo kumzi-mveliso kwaye ekugqibeleni zikhokelele kutshintsho kumaxabiso emveliso.
IXESHA LOKUQALA: Jun-25 ukuya kwi-2022
