"Isuku" akenshi birengagizwa mubikorwa bya PCBA byo gukora imbaho ​​zumuzunguruko, kandi bifatwa ko gukora isuku atari intambwe ikomeye. Ariko, hamwe nigihe kirekire cyo gukoresha ibicuruzwa kuruhande rwabakiriya, ibibazo biterwa no gukora isuku idakorwa mugihe cyambere bitera kunanirwa kwinshi, gusana cyangwa ibicuruzwa byagarutsweho byatumye kwiyongera gukabije kwibikorwa. Hasi, Heming Technology izasobanura muri make uruhare rwa PCBA isukura imbaho ​​zumuzunguruko.

Igikorwa cyo gukora PCBA (icapiro ryumuzunguruko wacapwe) kinyura mubyiciro byinshi, kandi buri cyiciro cyanduye kurwego rutandukanye. Kubwibyo, kubitsa cyangwa umwanda utandukanye biguma hejuru yumuzunguruko wa PCBA. Ibyo bihumanya bizagabanya ibicuruzwa Imikorere, ndetse binatera ibicuruzwa kunanirwa. Kurugero, mugikorwa cyo kugurisha ibikoresho bya elegitoronike, paste yo kugurisha, flux, nibindi bikoreshwa mugurisha kugurisha. Nyuma yo kugurisha, hasigara ibisigazwa. Ibisigazwa birimo aside organic na ion. Muri byo, acide organic izonona ikibaho cyumuzunguruko PCBA. Kubaho ion z'amashanyarazi birashobora gutera uruziga rugufi kandi bigatuma ibicuruzwa binanirwa.

Hariho ubwoko bwinshi bwanduye ku kibaho cyumuzunguruko PCBA, gishobora gukusanyirizwa mubice bibiri: ionic na non-ionic. Umwanda uhumanya Ionic uhura nubushuhe bwibidukikije, kandi kwimuka kwamashanyarazi bibaho nyuma yamashanyarazi, bigakora imiterere ya dendritic, bikavamo inzira nke yo guhangana, kandi bigasenya imikorere ya PCBA yubuyobozi bwumuzunguruko. Umwanda utari ionic urashobora kwinjirira murwego rwa PC B hanyuma ugakura dendrite munsi ya PCB. Usibye kwanduza ionic na non-ionic, hari kandi imyanda ihumanya, nk'imipira y'abagurisha, ingingo zireremba mu bwogero bw'abagurisha, umukungugu, umukungugu, n'ibindi. ingingo zikarishye mugihe cyo kugurisha. Ibintu bitandukanye bitifuzwa nka pore na sisitemu ngufi.

Hamwe n’imyanda myinshi, niyihe ihangayikishijwe cyane? Flux cyangwa kugurisha paste isanzwe ikoreshwa muburyo bwo kugurisha no kugurisha imiraba. Zigizwe ahanini nuwashonga, imiti itose, resin, inhibitori ya ruswa. Ibicuruzwa byahinduwe neza bigomba kubaho nyuma yo kugurisha. Ibi bintu Kubijyanye no kunanirwa kwibicuruzwa, ibisigazwa nyuma yo gusudira nibintu byingenzi bigira ingaruka kumiterere yibicuruzwa. Ibisigisigi bya Ionic birashoboka ko bitera electromigration kandi bikagabanya ubukana bwokwirinda, kandi ibisigazwa bya rosin byoroshye biroroshye adsorb Umukungugu cyangwa umwanda utera guhuza umubonano kwiyongera, kandi mubihe bikomeye, bizatera kunanirwa kumuzunguruko. Kubwibyo, isuku rikomeye rigomba gukorwa nyuma yo gusudira kugirango hamenyekane ubuziranenge bwumuzunguruko wa PCBA.

Muri make, gusukura ikibaho cyumuzunguruko PCBA ni ngombwa cyane. "Isuku" ninzira yingenzi ijyanye neza nubwiza bwumuzunguruko wumuzunguruko PCBA kandi ni ngombwa.
