Umuhengeri wo kugurisha intambwe nintambwe zo kwitabwaho.

1. Intambwe yo gukora yaimashini yo kugurisha.

1).Ibikoresho byo kugurishakwitegura mbere yo gusudira
Reba niba PCB igomba kugurishwa itose, niba abagurisha bahujwe na okiside, bahinduwe, nibindi.;flux ihujwe na interineti ya nozzle ya sprayer.

2).Gutangiza ibikoresho byo kugurisha
Hindura ubugari bwimashini igurisha imashini itwara imashini (cyangwa fixture) ukurikije ubugari bwibibaho byacapwe;fungura imbaraga n'imikorere ya buri mufana wa mashini yo kugurisha.

3).Shiraho ibipimo byo gusudira ibikoresho byo kugurisha umuraba
Flux Flow: Ukurikije uko flux ihuza hepfo ya PCB.Flux irasabwa gutwikirwa neza hepfo ya PCB.Guhera mu mwobo uri kuri PCB, hagomba kubaho umuvuduko muke hejuru yumwobo unyuze mu mwobo ugana kuri padi, ariko ntiwinjire

Ubushyuhe bwo gushyushya: shyira ukurikije uko ibintu byifashe mu ziko ryashyushye rya microwave (ubushyuhe nyabwo hejuru yubuso bwa PCB muri rusange ni 90-130 ° C, ubushyuhe bwisahani yibyibushye ni rwo rugabano rwo hejuru ku kibaho cyateranijwe hamwe nibindi byinshi Ibigize SMD, kandi ubushyuhe bwo kuzamuka buringaniye buri munsi cyangwa bingana na 2 ° C / S;

Umuvuduko wumukandara: ukurikije imashini zitandukanye zo kugurisha hamwe na PCB igurishwa (muri rusange 0.8-1.60m / min);ubushyuhe bw'abagurisha: (bigomba kuba ubushyuhe nyabwo bwerekanwe ku gikoresho (SN-Ag-Cu 260 ± 5 ℃, SN-Cu 265 ± 5 ° C) Kubera ko icyuma cy'ubushyuhe kiri mu bwogero bw'amabati, ubushyuhe bwa metero cyangwa LCD iri hejuru ya 3 ° C hejuru yubushyuhe bwo hejuru;

Ibipimo by'uburebure bwo hejuru: iyo birenze hepfo ya PCB, hindura kuri 1/2 ~ 2/3 by'ubugari bwa PCB;

Inguni yo gusudira: impengamiro yo kohereza: 4.5-5.5 °;igihe cyo gusudira: muri rusange amasegonda 3-4.

4).Igicuruzwa kigomba kuzunguruka no kugenzurwa (nyuma yuko ibipimo byose byo gusudira bigera ku giciro cyagenwe)
Shyira witonze ikibaho cyumuzingo cyanditse kumukandara wa convoyeur (cyangwa fixture), imashini ihita itera imbavu, preheats, abagurisha imiraba hamwe na cool;icyapa cyumuzingo cyacapwe gihujwe no gusohoka kugurisha umuyaga;ukurikije igipimo cyo kugenzura uruganda.

5).Hindura ibipimo byo gusudira ukurikije ibisubizo byo gusudira PCB

6).Kora umusaruro uhoraho wo gusudira, guhuza ikibaho cyumuzingo cyacapwe kumasoko yo kugurisha imiraba, ubishyire mubisanduku birwanya ibicuruzwa nyuma yo kugenzura, hanyuma wohereze akanama gashinzwe kubungabunga ibicuruzwa bitunganijwe nyuma;mugihe cyo gukomeza gusudira, buri kibaho cyacapwe kigomba kugenzurwa, kandi inenge yo gusudira Ikibaho cyacapwe gikwiye kongera kugurishwa ako kanya.Niba hakiri inenge nyuma yo gusudira, impamvu igomba kuboneka, kandi gusudira bigomba gukomeza nyuma yo guhindura ibipimo.

2. Ingingo zo kwitabwaho mubikorwa byo kugurisha imiraba.

1).Mbere yo kugurisha umuraba, genzura imikorere yimikorere yibikoresho, ubwiza bwikibaho cyumuzingo cyacapishijwe kugurishwa hamwe nucomeka.

2).Muburyo bwo kugurisha imiraba, ugomba guhora witondera imikorere yibikoresho, ugasukura okiside hejuru yubwogero bwamabati mugihe, ukongeramo polifhenylene ether cyangwa amavuta ya sesame nizindi antioxydants, hanyuma ukuzuza uwagurishije mugihe.

3).Nyuma yo kugurisha umuraba, ubwiza bwo gusudira bugomba kugenzurwa kumurongo.Ku mubare muto wabuze kugurisha no kugurisha ibiraro, gusudira intoki bigomba gukorwa mugihe.Niba hari umubare munini wibibazo byo gusudira, shakisha impamvu mugihe.

Kugurisha imiraba nubuhanga bukuze bwo kugurisha inganda.Nyamara, hamwe numubare munini wibisabwa byubuso bwububiko bwububiko, uburyo bwo guteranya ibice byo gucomeka hamwe nibice byo hejuru byububiko byakusanyirijwe ku kibaho cyumuzunguruko icyarimwe byahindutse uburyo rusange bwo guterana mubicuruzwa bya elegitoroniki, bityo bigatanga byinshi mubikorwa ya tekinoroji yo kugurisha.Kugirango huzuzwe ibisabwa bikomeye, abantu baracyahora bashakisha uburyo bwo kuzamura ubwiza bwigurisha ryogucuruza imiraba, harimo: gushimangira kugenzura ubuziranenge bwibishushanyo mbonera by’imashini byacapwe hamwe n’ibigize mbere yo kugurisha;kunoza ibikoresho byuburyo nka flux nugurisha Kugenzura ubuziranenge;mugihe cyo gusudira, hindura ibipimo byubushakashatsi nko gushyushya ubushyuhe, gusudira inzira, uburebure bwumuraba, ubushyuhe bwo gusudira nibindi.
