Twese twizera ko inzira ya SMT itunganye, ariko ukuri ni ubugome.Ibikurikira nubumenyi bumwe mubibazo bishoboka kubicuruzwa bya SMT hamwe nuburyo bwo guhangana nabyo.
Ibikurikira, turasobanura ibyo bibazo muburyo burambuye.
1. Ikintu cyo kumva
Imva, nkuko bigaragara, nikibazo aho impapuro zizamuka kuruhande rumwe.Iyi nenge irashobora kubaho mugihe ubuso bwubuso bwimpande zombi zidafite uburinganire.
Kurinda ibi kubaho, turashobora:
- Kongera igihe muri zone ikora;
- Kunoza igishushanyo mbonera;
- Irinde okiside cyangwa kwanduza ibice birangira;
- Hindura ibipimo byimashini zigurisha imashini zimashini zimashini;
- Kunoza igishushanyo mbonera.
Ikiraro cyagurishijwe
Iyo paste igurisha ikora ihuza ridasanzwe hagati ya pin cyangwa ibice, byitwa ikiraro cyagurishijwe.
Ingamba zo guhangana zirimo:
- Hindura printer kugirango ugenzure imiterere yanditse;
- Koresha paste yagurishijwe hamwe nubwiza bukwiye;
- Gutezimbere aperture kurugero;
- Hindura neza gutoranya no gushyira imashini kugirango uhindure ibice hanyuma ukoreshe igitutu.
3. Ibice byangiritse
Ibigize birashobora kugira ibice niba byangiritse nkibikoresho fatizo cyangwa mugihe cyo gushyira no kugaruka
Kurinda iki kibazo:
- Kugenzura no guta ibikoresho byangiritse;
- Irinde guhuza ibinyoma hagati yimashini nimashini mugihe cyo gutunganya SMT;
- Igenzura igipimo cyo gukonja kiri munsi ya 4 ° C kumasegonda.
4. ibyangiritse
Niba amapine yangiritse, azamura amakariso kandi igice ntigishobora kugurishwa.
Kugira ngo twirinde ibi, tugomba:
- Reba ibikoresho kugirango uta ibice ukoresheje pin mbi;
- Kugenzura ibice byashyizwe mu ntoki mbere yo kubyohereza muburyo bwo kugaruka.
5. Umwanya mubi cyangwa icyerekezo cyibice
Iki kibazo gikubiyemo ibintu byinshi nko kudahuza cyangwa icyerekezo kibi / polarite aho ibice bisudira mubyerekezo bitandukanye.
Ingamba zo guhangana:
- Gukosora ibipimo byimashini ishyira;
- Reba ibice byashyizwe mu ntoki;
- Irinde amakosa yo guhura mbere yo kwinjira muburyo bwo kugaruka;
- Hindura umwuka mugihe cyo kugaruka, bishobora guhita igice kiva mumwanya wacyo.
6. Ikibazo cya paste
Ishusho yerekana ibintu bitatu bijyanye nubunini bwa paste paste:
(1) Ugurisha birenze
(2) Umugurisha udahagije
(3) Nta ugurisha.
Hariho ibintu 3 ahanini bitera ikibazo.
1) Ubwa mbere, imyenge yicyitegererezo irashobora guhagarikwa cyangwa atariyo.
2) Icya kabiri, ibishishwa bya paste yagurishijwe ntibishobora kuba byiza.
3) Icya gatatu, kugurishwa nabi kwibigize cyangwa padi birashobora kuvamo bidahagije cyangwa nta ugurisha.
Ingamba zo guhangana:
- icyitegererezo gisukuye;
- Menya neza guhuza inyandikorugero;
- Kugenzura neza ingano yubucuruzi bwa paste;
- Hagarika ibice cyangwa udupapuro dufite solderabilité nkeya.
7. Guhuza abadasanzwe bidasanzwe
Niba intambwe zimwe zo kugurisha zitagenda neza, ingingo zigurisha zizakora imiterere itandukanye kandi itunguranye.
Imyobo idahwitse ishobora kuvamo (1) imipira yo kugurisha.
Oxidisation ya padi cyangwa ibice, umwanya udahagije mugice cya soak no kuzamuka byihuse kwubushyuhe bwo kugaruka bishobora gutera imipira yabagurisha na (2) umwobo wabagurisha, ubushyuhe buke bwo kugurisha nigihe gito cyo kugurisha bishobora gutera (3) icicles.
Ingamba zo guhangana nizo zikurikira:
- icyitegererezo gisukuye;
- Guteka PCB mbere yo gutunganya SMT kugirango wirinde okiside;
- Hindura neza ubushyuhe mugihe cyo gusudira.
Ibyavuzwe haruguru nibibazo bisanzwe byubuziranenge nibisubizo byatanzwe nu ruganda rugurisha ibicuruzwa bya Chengyuan Inganda mubikorwa bya SMT.Nizere ko bizagufasha.
