Umurongo wo kubyara SMT ni iki

Gukora ibikoresho bya elegitoronike ni bumwe mu buryo bwingenzi bwinganda zikoranabuhanga.Kubyakozwe no guteranya ibicuruzwa bya elegitoronike, PCBA (icapiro ryumuzunguruko wacapwe) nigice cyibanze kandi cyingenzi.Hano haribisanzwe SMT (Surface Mount Technology) na DIP (Dual in -line pack).

Intego yo gukurikirana mubikorwa byinganda za elegitoronike niyongera ubwinshi bwimikorere mugihe igabanya ingano, ni ukuvuga gukora ibicuruzwa bito kandi byoroshye.Muyandi magambo, ikigamijwe ni ukongera imirimo myinshi kumurongo umwe wumuzunguruko cyangwa kugumana imikorere imwe ariko kugabanya ubuso.Inzira yonyine yo kugera ku ntego ni ukugabanya ibice bya elegitoroniki, kubikoresha kugirango bisimbuze ibice bisanzwe.Nkigisubizo, SMT yateye imbere.

Ikoranabuhanga rya SMT rishingiye ku gusimbuza ibyo bikoresho bya elegitoroniki bisanzwe na wafer-ubwoko bwibikoresho bya elegitoronike no gukoresha in-tray kubipakira.Muri icyo gihe, uburyo busanzwe bwo gucukura no gushyiramo bwasimbujwe paste yihuse hejuru ya PCB.Byongeye kandi, ubuso bwa PCB bwaragabanutse mugutezimbere ibice byinshi byimbaho ​​uhereye kumurongo umwe.

Ibikoresho nyamukuru byumurongo wa SMT urimo: Icapa rya Stencil, SPI, imashini itoranya nu mwanya, kwerekana ifuru yo kugurisha, AOI.

Inyungu ziva mubicuruzwa bya SMT

Gukoresha SMT kubicuruzwa ntabwo bigenewe isoko gusa ahubwo ningaruka zayo zitaziguye mukugabanya ibiciro.SMT igabanya ikiguzi kubera ibi bikurikira:

1. Ubuso bukenewe hamwe nibice bya PCB biragabanuka.

Ubuso bukenewe bwa PCB bwo gutwara ibice buragabanuka kuko ubunini bwibyo bikoresho byo guteranya bwaragabanutse.Byongeye kandi, ikiguzi cyibikoresho bya PCB kiragabanuka, kandi kandi ntamafaranga yandi yo gutunganya yo gucukura kubwobo.Ni ukubera ko kugurisha PCB muburyo bwa SMD butaziguye kandi buringaniye aho kwishingikiriza kumapine yibigize muri DIP kunyura mumyobo yacukuwe kugirango bigurishwe PCB.Mubyongeyeho, imiterere ya PCB igenda ikora neza mugihe hatabayeho gucukurwa, kandi nkigisubizo, ibice bisabwa bya PCB biragabanuka.Kurugero, mubusanzwe ibice bine byubushakashatsi bwa DIP birashobora kugabanuka mubice bibiri kuburyo bwa SMD.Ni ukubera ko mugihe ukoresheje uburyo bwa SMD, ibice bibiri byimbaho ​​bizaba bihagije kugirango bikwiranye ninsinga zose.Igiciro cyibice bibiri byimbaho ​​birumvikana ko biri munsi yibyo bine byimbaho.

2. SMD irakwiriye kubwinshi mubikorwa

Gupakira kuri SMD bituma ihitamo neza kubyara umusaruro.Nubwo kuri ibyo bikoresho bisanzwe bya DIP, hariho nuburyo bwo guteranya byikora, kurugero, ubwoko butambitse bwimashini yinjizamo, ubwoko bwa vertical ya mashini yinjizamo, imashini yinjiza idasanzwe, na mashini yinjiza IC;nonese, umusaruro kuri buri gihe igice uracyari munsi ya SMD.Nkuko umusaruro wiyongera kuri buri gihe cyakazi, igice cyibiciro byumusaruro kiragabanuka.

3. Harasabwa abakoresha bake

Mubisanzwe, abashoramari bagera kuri batatu gusa basabwa kumurongo wa SMT, ariko byibuze abantu 10 kugeza kuri 20 basabwa kumurongo wa DIP.Mugabanye umubare wabantu, ntabwo ikiguzi cyabakozi kigabanuka gusa ahubwo nubuyobozi buroroha.
