8.How tso rau qhov kub rau BGA nti txhuas rau soldering
Nrog rau kev siv thoob plaws ntawm cov chips, peb kuj tau them ntau dua thiab ntau mloog rau qhov teeb meem ntawm nti ua haujlwm. Tam sim no, muaj ob hom BGA chips siv hauv kev ua lag luam. Ib tug yog ua, tus lwm yog hmoov txhuas dawb, khoom-dawb BGA Cov Khoom Siv Sib Txawv Daus Tawv Kub? Tom ntej no Dinghua thev naus laus zis thev naus laus zis yuav muab cov lus qhia rau koj.
Nyob rau hauv ib txwm muaj xwm txheej, qhov ntsuas kub yuav tsum muaj lead-dawb bga chips yog nruj heev thaum lub sij hawm sib dhos. Qhov kub ntawm uas lub suab nrov ntawm cov hmoov txhuas dawb ntawm cov hmoov txhuas dawb yog li 35 degrees loj dua li cov hmoov txhuas uas tsis muaj txiaj ntsig BGA. Lead BGA chips yuav tsum to taub nws cov yam ntxwv ua ntej siv cov. Feem ntau hais lus, lub ntsiab lus melting ntawm cov hmoov txhuas-dawb solder soldering sib txawv raws li cov txhuas cov solder muab tshuaj txhuam. Ntawm no peb muab ob qhov tseem ceeb raws li kev siv. Lub ntsiab lus melting ntawm tin-nyiaj-tooj-tooj liab alloy yog li 217 degrees, thiab lub suab nrov ntawm cov hamloy alloy yog hais txog 227 degrees. Hauv qab no ob qhov kub thiab txias, ham muab tshuaj yuav tsis tau melted vim muaj cua sov tsis txaus. Thaum muas BGA rework chaw nres tsheb, koj kuj yuav tsum tau them sai sai rau kev sab laj rau kev tsim khoom txog qhov kub thiab txias bga nti. Seb lub cuab yeej tuaj yeem ntsib qhov ntsuas kub. Yog tias tsis yog, koj yuav tsum xav txog yuav. Feem ntau, qhov kub hauv cov cub-dawb txhuas yuav tsum yog kwv yees li 10 degrees. Cov hauv qab no yog cov lus qhia ntxaws ntxaws:
| Alloying Cov Khoom Noj | Melting taw tes (degree) |
| Sn99ag {0. 3cu 0. 7 | 217-221 |
| Sn95.5ag4cu 0. 5 | 217-219 |
| Sn95.5ag3.8cu 0. 7 | 217-220 |
| Sn95.7ag3.8cu 0. 5 | 217-219 |
| Sn96.5ag3cu 0. 5 | 216-217 |
| Sn98.5AG 0. 5cu1 | 219-221 |
| SN96.5CU3.5 | 211-221 |
| Sn99cu1 | 225-227 |
Thaum ua haujlwm ua-dawb bga nti soldering, peb feem ntau siv tag nrho cov ntawv hlau los ua kom cov cua sov kom ua rau kom muaj kab ke uas cov cua sov kab noj hniav tsis kub. Txawm li cas los xij, muaj ntau ntau cov tuam txhab tsis zoo uas siv cov hlau me me ntawm cov hlau rau splice rau hauv cov cub tawg kom sib tw rau tus nqi. Cov cuab yeej siv no feem ntau pom yog tias koj tsis them sai sai rau nws, tab sis warp kev puas tsuaj yuav tshwm sim yog tias nws yog nyob rau hauv cov kub siab.
Cov hmoov txhuas nti BGA tseem ceeb rau kev sim ua kev sib tw ntawm txoj kev kub ntxhov thaum lub sijhawm no yuav cuam tshuam nrog kev ua tiav kev ua tiav ntawm BGA nti. Yog tias cov ntaub ntawv thiab tsim qauv ntawm cov khoom siv BGA rework ua rau cov kev ua haujlwm yooj yim hauv qab qhov kev mob siab, nws yuav ua rau daim npav jamming lossis poob. Cov pa sn63pb37 coj cov cam yog Euteccing Alloy, thiab nws cov lus sib tw thiab khov ua ke ntawm snagcu tsis yog eutectic alloys, thiab lawv cov ntsiab lus melting ntau ntawm 217 Qib C rau 221 degree c, ntsuas kub qis dua 217 degree c yog cov khoom, thiab kub siab tshaj plaws saum 221 degree c yog kua. Thaum qhov ntsuas kub nyob nruab nrab ntawm 217 Degree C thiab 221 degree c lub alloy qhia ib lub xeev tsis ruaj khov
