7.Kev paub txog
Dab tsi yog kev ceev faj rau cov txheej txheem SMT thaj?
Cia kub: Nws raug pom zoo tias qhov ntsuas kub hauv lub tub yees yog 5 degree -10 degree, ua
tsis poob qis dua 0 degree .
Outbound txoj cai: Koj yuav tsum ua raws li lub hauv paus ntsiab lus ntawm first-in, first-out, thiab tsis txhob ua solder muab tshuaj txhuam rau khaws cia
nyob rau hauv lub freezer ntev heev.
Thawing yuav tsum tau: Ib txwm thaw rau yam tsawg kawg yog 4 teev tom qab tshem cov solder paste los ntawm lub freezer.
Tsis txhob qhib lub hau thaum thawing.
Kev tsim khoom ib puag ncig: Nws raug pom zoo tias lub khw kub yog 25 ± 2 degree thiab cov av noo txheeb ze
yuav tsum yog 45%-65%RH.
Siv Tshuaj Txhuam: Tom qab qhib lub hau, nws raug nquahu kom siv nws li ntawm 12 teev. Yog tias nws yuav tsum tau khaws cia, thov
siv lub raj mis huv huv, khoob, tom qab ntawd kaw nws thiab muab tso rau hauv lub freezer.
Tus nqi ntawm cov muab tshuaj tso rau ntawm cov hlau net: Tus nqi ntawm cov tshuaj muab tshuaj tso rau ntawm cov hlau hlau rau thawj zaug
lub sij hawm yuav tsum tsis txhob tshaj 1/2 ntawm qhov siab ntawm lub scraper thaum luam ntawv thiab dov.
Thib ob, SMT nti ua cov txheej txheem luam ntawv yuav tsum tau them sai sai rau:
1.Scraper: Cov khoom siv scraper zoo dua yog cov hlau scraper, uas yog qhov zoo rau kev tsim thiab stripping.
ntawm cov tshuaj nplaum luam tawm ntawm PAD.
Squeegee lub kaum sab xis: Phau ntawv luam ntawv yog 45-60 degrees; tshuab luam ntawv yog 60 degrees.
Printing ceev: Phau ntawv 30-45mm/min; tshuab luam ntawv 40mm-80mm/min.
Kev luam ntawv ib puag ncig: Kub yog 23 ± 3 degree thiab txheeb ze av noo yog 45% -65% RH.
2. Steel mesh: Steel mesh qhib raws li qhov yuav tsum tau ntawm cov khoom, xaiv cov thickness ntawm cov
steel mesh thiab cov duab thiab qhov piv ntawm qhov qhib.
QFP\CHIP: CHIPs nrog nruab nrab pitches tsawg dua 0.5mm thiab 0402 yuav tsum tau laser txiav.
Test steel mesh: Kev ntsuas nro ntawm cov hlau mesh yog ua ib zaug ib lub lim tiam, thiab tus nqi nro yuav tsum tau
los yog 35N / cm2.
Ntxuav cov stencil: Thaum luam ntawv 5-10 pcs ntawm PCBs ua ke, ntxuav nws nrog lub wiper huv. Nws yog qhov zoo tshaj kom tsis txhob siv rags.
3. Cov tshuaj ntxuav: IPA hnyav: IPA thiab cawv hnyav yog qhov zoo tshaj plaws los siv thaum ntxuav stencils. Nws siv tsis tau
chlorine-muaj cov kuab tshuaj vim tias cov tshuaj muaj pes tsawg leeg yuav raug rhuav tshem thiab tag nrho cov khoom yuav zoo
raug cuam tshuam.
