Mugutunganya PCBA, ubuziranenge bwo gusudira bwumuzunguruko bugira ingaruka zikomeye kumikorere no kugaragara byubuyobozi bwumuzunguruko. Kubwibyo, ni ngombwa cyane kugenzura ubuziranenge bwo gusudira bwibibaho byumuzunguruko wa PCB.Ikibaho cyumuzunguruko wa PCBubuziranenge bwo gusudira bufitanye isano cyane nigishushanyo mbonera cyumuzunguruko, ibikoresho byo gutunganya, tekinoroji yo gusudira nibindi bintu.
一 Igishushanyo mbonera cyumuzunguruko wa PCB
1. Igishushanyo mbonera
. Niba padi ari nini cyane, umugurisha ukwirakwiza ahantu hanini, kandi ingingo zagurishijwe zakozwe ntabwo zuzuye. Kurundi ruhande, uburemere bwubuso bwumuringa wumuringa wa padi ntoya ni nto cyane, kandi ingingo zigurisha zakozwe ni ingingo zidacuruza. Ikinyuranyo gihuye hagati ya aperture nibice biganisha ni binini cyane kandi biroroshye gutera kugurisha ibinyoma. Iyo aperture ari 0,05 - 0.2mm mugari kurenza isasu na diameter ya padi inshuro 2 - 2,5 aperture, nibintu byiza byo gusudira.
. guhura na tin itemba. Mugabanye kugurisha ibinyoma no kubura kugurisha. Ibice bito ntibigomba gushyirwaho nyuma yibice binini kugirango birinde ibice binini kutabangamira kugurisha no guhuza amakarito yibice bito, bikavamo kugurisha.
2 control PCB yumuzunguruko wibibaho
Kugurisha imiraba bifite ibyangombwa byinshi hejuru yuburinganire bwanditse. Mubisanzwe, urupapuro rwintambara rusabwa kuba munsi ya 0.5mm. Niba irenze 0.5mm, igomba guhindurwa. By'umwihariko, ubunini bwibibaho bimwe byacapwe ni 1.5mm gusa, kandi ibisabwa byintambara ni byinshi. Bitabaye ibyo, ubuziranenge bwo gusudira ntibushobora kwemezwa. Ibibazo bikurikira bigomba kwitabwaho:
(1) Kubika neza imbaho zacapwe nibigize kandi ugabanye igihe cyo kubika bishoboka. Mugihe cyo gusudira, ifiriti yumuringa hamwe nibigize biganisha ku mukungugu, amavuta, na okiside bifasha muburyo bwo kugurisha neza. Kubwibyo, imbaho zacapwe nibigize bigomba kubikwa ahantu humye. , mubidukikije bisukuye, kandi ugabanye igihe cyo kubika bishoboka.
(2) Kubibaho byacapwe byashyizwe mugihe kirekire, ubusanzwe bigomba gusukurwa. Ibi birashobora kunoza kugurisha no kugabanya kugurisha no kubeshya. Kuri pin yibigize hamwe nurwego runaka rwa okiside yubuso, ubuso bugomba gukurwaho mbere. oxyde.
二. Kugenzura ubuziranenge bwibikoresho
Mugurisha umuraba, ibikoresho byingenzi bikoreshwa ni: flux nugurisha.
1. Gukoresha flux birashobora gukuraho okiside hejuru yubudodo, bikarinda kongera okiside yuwagurishije hamwe nubuso bwo gusudira mugihe cyo gusudira, kugabanya ubukana bwubuso bwumugurisha, kandi bigafasha kwimurira ubushyuhe ahantu ho gusudira. Flux igira uruhare runini mugucunga ubuziranenge bwo gusudira.
2. Kugenzura ubuziranenge kubagurisha
Ugurisha amabati akomeje okiside mu bushyuhe bwo hejuru (250 ° C), bigatuma amabati y’umugurisha wa tin-gurş yagurishijwe mu nkono y’amabati ahora agabanuka kandi agatandukana na eutectic, bikaviramo amazi mabi n’ibibazo byiza nko gukomeza kugurisha, kugurisha ubusa, no kugurisha bidahagije imbaraga. .
三 、 Igikoresho cyo gusudira kugenzura
Ingaruka yuburyo bwo gusudira ibipimo byo gusudira ubuziranenge burasa.
Hariho ingingo nyinshi zingenzi: 1. Kugenzura ubushyuhe bwubushyuhe. 2. Inguni yo gusudira. 3. Uburebure bwa crest. 4. Ubushyuhe bwo gusudira.
Gusudira nintambwe yingenzi mubikorwa bya PCB byumuzunguruko. Kugirango hamenyekane ubuziranenge bwo gusudira ku kibaho cyumuzunguruko, umuntu agomba kuba afite ubuhanga bwo kugenzura ubuziranenge nubuhanga bwo gusudira.
