SMD processing yog ib qho kev sim uas yuav tsum tau ua, SPI (Solder Paste Inspection) yog cov txheej txheem SMD ua cov txheej txheem, siv los xyuas qhov zoo ntawm solder paste luam ntawv zoo lossis phem.Vim li cas koj thiaj xav tau cov cuab yeej spi tom qab solder paste luam ntawv?Vim tias cov ntaub ntawv los ntawm kev lag luam txog 60% ntawm qhov zoo ntawm soldering yog vim tsis zoo solder paste luam ntawv (tus so tej zaum yuav muaj feem xyuam rau lub thaj, reflow txheej txheem).
SPI yog qhov kuaj pom ntawm qhov tsis zoo solder paste luam ntawv,SMT SPI tshuabyog nyob rau sab nraum qab ntawm lub tshuab luam ntawv tshuab luam ntawv, thaum lub tshuab luam ntawv muab tshuaj tom qab luam tawm ib daim ntawm pcb, los ntawm kev sib txuas ntawm lub rooj conveyor rau hauv SPI cov cuab yeej kuaj xyuas kom pom nws cov kev luam ntawv zoo.
SPI tuaj yeem txheeb xyuas qhov teeb meem tsis zoo?
1. Txawm tias cov tshuaj txhuam hniav yog tin
SPI tuaj yeem kuaj xyuas seb puas yog lub tshuab luam ntawv luam ntawv tshuab luam ntawv tin, yog pcb nyob ib sab pads txawm tias tin, nws yuav yooj yim ua rau luv luv.
2. Paste offset
solder paste offset txhais tau hais tias lub solder paste luam ntawv tsis yog luam tawm ntawm lub pcb pads (los yog tsuas yog ib feem ntawm lub solder paste luam tawm ntawm lub ncoo), solder paste printing offset yog zoo li yuav ua rau khoob soldering los yog sawv monument thiab lwm yam tsis zoo.
3. Tshawb xyuas qhov tuab ntawm cov nplaum nplaum
SPI kuaj xyuas qhov tuab ntawm cov tshuaj txhuam hniav, qee zaum cov nyiaj ntawm cov tshuaj txhuam hniav ntau dhau, qee zaum cov nqi ntawm cov tshuaj txhuam hniav tsawg dua, qhov teeb meem no yuav ua rau vuam vuam lossis vuam khoob.
4. Txheeb xyuas qhov flatness ntawm solder paste
SPI kuaj xyuas qhov flatness ntawm cov tshuaj txhuam hniav, vim tias lub tshuab luam ntawv muab tshuaj txhuam yuav raug demolded tom qab luam ntawv, qee qhov yuav tshwm sim rub lub taub, thaum lub flatness tsis yog tib lub sij hawm, nws yog ib qho yooj yim ua rau vuam tsis zoo.
SPI nrhiav tau qhov zoo ntawm kev luam ntawv li cas?
SPI yog ib qho ntawm cov khoom siv kho qhov muag, tab sis kuj dhau los ntawm cov khoom siv kho qhov muag thiab lub khoos phis tawj algorithms kom ua tiav lub hauv paus ntsiab lus ntawm kev tshawb nrhiav, solder paste luam ntawv, spi los ntawm lub koob yees duab sab hauv lub lens ntawm lub koob yees duab kom rho tawm cov ntaub ntawv, thiab tom qab ntawd algorithm lees paub ua ke. nrhiav pom cov duab, thiab tom qab ntawd nrog cov ntaub ntawv ok piv txwv rau kev sib piv, thaum piv rau ok mus txog tus qauv yuav raug txiav txim siab raws li lub rooj tsav xwm zoo, thaum piv rau ok tsis tau tshaj tawm lub tswb, cov kws tshaj lij tuaj yeem yog Cov Kws Kho Mob tuaj yeem ncaj qha tshem tawm qhov tsis xws luag. boards los ntawm txoj siv conveyor
Vim li cas SPI kev tshuaj xyuas tau nrov dua?
Tsuas yog hais tias qhov yuav tshwm sim ntawm vuam tsis zoo vim yog solder paste luam tawm los ntawm ntau tshaj 60%, yog tias tsis yog tom qab spi xeem los txiav txim siab phem, nws yuav ncaj qha tom qab thaj, reflow soldering txheej txheem, thaum ua tiav ntawm vuam thiab tom qab aoi kuaj pom qhov tsis zoo, ntawm ib sab, kev saib xyuas ntawm qib ntawm qhov teeb meem yuav phem dua li spi los txiav txim siab lub sij hawm ntawm qhov teeb meem tsis zoo (SPI kev txiav txim siab ntawm kev luam ntawv tsis zoo, ncaj qha los ntawm txoj siv conveyor kom tshem tawm, ntxuav tawm cov tshuaj txhuam) , ntawm qhov tod tes, tom qab vuam, lub rooj tsav xwm tsis zoo tuaj yeem siv tau dua, thiab tom qab vuam, tus kws tshaj lij tuaj yeem nqa lub rooj tsav xwm tsis zoo los ntawm txoj siv conveyor.Yuav siv tau dua), ntxiv rau kev kho vuam yuav ua rau cov neeg siv khoom pov tseg ntau dua, cov khoom siv thiab nyiaj txiag.
