SMD kugadzirisa kutanga inoda kukwenya dhizaini ye solder paste pamusoro pe pcb pad, solder paste kudhinda kunofanirwa kuitwa mushure memhando yebvunzo, edza zita remuchina unonzi spi (solder paste yekuyedza muchina), iyo huru. bvunzo yekudhinda paste paste kana paine offset, dhonza muromo, ukobvu uye flatness, nezvimwewo, nekuti mhando ye solder paste kudhinda kunokanganisa zvakananga kunaka kweiyo weld kuseri, iyo indasitiri weld chikonzero chehurombo. kupfuura 60% yematambudziko ndiko kudhindwa kweiyo solder paste!Inokonzerwa neanopfuura 60% yezvinokonzera murombo soldering muindasitiri ndiyo solder namira kudhinda matambudziko, zvakakwana kuratidza kukosha sei solder namira kudhinda bvunzo.
Zvinoreva SPI kuburikidza nechiyero
Solder Paste Printing Inspection (SPI) neAOI yekuongorora ine mwero wakatwasuka, wakatwasuka kuburikidza nechiyero kubva paizwi unogona kunyatsonzwisiswa, zvakananga kuburikidza nemukana, unogona zvakare kuve chiyero chekubudirira, kukwira kwakatwasuka kuburikidza nechiyero, kunowedzera kugadzirwa. uye simba rekugadzira, kana iyo yakananga kuburikidza nechiyero yakaderera, zvinoreva kuti iyo nzira haishande, inokanganisa kugona kwekuita.
Kukosha kwekunanga kuburikidza nechiyero chekudzora
Kururama kuburikidza nechiyero kunoratidzawo mwero webudiriro, iyo yakakwira yakatwasuka kuburikidza nechiyero, iyo yakakwira mwero wekugadzira tekinoroji, mukana wekufamba kwakananga, uye kwete kugara uchitaura zvakaipa kana zvisizvo, zvakananga kuburikidza nechiyero chakakwira, kugadzirwa kwepamusoro, kugona kukuru, yakananga kuburikidza nechiyero yakaderera, kushaikwa kwehunyanzvi hwekugadzira, uye kuchakanganisa kugadzirwa kwehunyanzvi uye mutengo wenguva, asi zvakare zvisina kunanga zvinotungamira kumutengo weakawanda manpower, mari yezvinhu kugadzirisa.Naizvozvo, iyo yakatwasuka-kuburikidza chiyero chekutonga kwechigadzirwa chekugadzira haingomiriri mwero wemhando yekugadzira, asi zvakare ine chekuita nekubudirira kwekugadzira fekitori.
Zvinhu zvinokanganisa spi kuburikidza nechiyero
Solder Paste
Kana iyo liquidity ye solder paste yakakurisa, zviri nyore kuita kuti solder paste ishanduke uye iputsike padhi, zvichikonzera kusadhinda kwakashata, tinofanira kushandisa solder paste kuti tidzoke zvakakwana kune tembiricha uye kubvongodza.
Squeegee
Squeegee pressure, speed, angle ichakanganisa kuwanda kwe solder paste yakadhindwa pa pcb pad (hukobvu uye flatness), kana ukobvu hwakawandisa kana hushoma, huchakonzeresa kupfupika kana kuti simbi isina chinhu.
Saizi yegomba restencil uye kutsetseka kwemadziro egomba kuchakanganisa solder paste seepage, uye kana stencil gomba madziro aine bvudzi, zvichave zvakare nyore kukonzera solder paste zvakasara.
