Cov roj ntsha ua ke yog thermosetting, thermoplastic polymer cob uas ua rau lub ntuj tawv, nrog rau cov ntaub ntawv zoo nrog cov ntawv sau. Nws yog siv los ua hluav taws xob insulating khoom.
Nws yog qhov tsim nyog
- - Cov phom cua kub;
- - ib tug txhuam hniav;
- - tweezers.
Cov Lus Qhia
Kauj ruam 1
Siv cov cuab yeej hauv qab no kom tshem tawm qhov kev sib txuas: rab phom cua kub, rab koob ntse ntse, ntse tawv tawv ntoo txhuam hniav, nyias tweezers. Teem lub ntsuas kub ntawm lub tshuab ziab plaub hau ntev txog 200 degrees, pib ua kom sov cov khoom sib txuas ua ke ntawm ntug ntawm microcircuit kom txog thaum nws muag muag (qhov no tuaj yeem kuaj nrog rab koob) Sai li cov txheej txheem softening pib, sim tshem tawm qhov sib txuas, lossis theej nws txheej sab saum toj, nrog tib rab koob. Siv koj lub sijhawm kom tsis txhob ua kom cov board.
Kauj ruam 2
Tshem tawm qhov chaw seem ntawm pawg thawj coj, nrog rau cov npoo ntawm microcircuit nrog cov pas txhuam hniav tom qab txheej nyias nyias nyob ntawm npliag txiag. Ntxiv mus, tom qab ua tiav cov kauj ruam no, koj yuav tsum muaj microcircuit ntxuav ntawm qhov sib txuas.
Kauj ruam 3
Tom qab ntawd koj yuav tsum tau tshem tawm cov microcircuit. Ua qhov no, teeb tsa kub ntawm lub tshuab ziab plaub hau los ntawm 270 txog 290 degrees thiab pib ua kom sov cov microcircuit kom txog thaum cov pob ntawm cov tshuaj pom tshwm. Rhaub nws rau lwm feeb thiab ib nrab, tom qab ntawd sim nqa ib sab ntawm qhov ntawm Circuit Court nrog tweezers. Tshem tawm nws, tom qab ntawd tshem tawm qhov seem ntawm qhov sib txuas ntawm pawg thawj coj thiab microcircuit hauv tib txoj kev ib yam li nyob rau hauv cov kauj ruam dhau los.
Kauj ruam 4
Tshem cov compound tawm ntawm microcircuit hauv lwm txoj kev. Txhawm rau ua qhov no, kho lub rooj tsavxwm hauv qab lub tshuab tsom, kom sov nws nrog lub tshuab ziab plaub hau (220 degrees), tshem tawm cov kab sib txuas ib ncig ntawm lub voj voos nrog tweezers. Txhuam cov khib nyiab. Tom ntej no, nteg cov nplaim taws ncig ntawm puag ncig.
Kauj ruam 5
Tshav kub txog 300 degrees, tom qab ib nrab ib pliag hno cov compound nyob hauv microcircuit los ntawm qhov kawg siv cov tweezers. Tus flux yuav nkag mus rau hauv cov qhov no, maj mam nqa lub microcircuit nrog cov tweezers thiab cua ntxias ncig nws. Tshem tawm cov ziab, tom qab ntawd txo cov cua kub kom txog 200 degrees thiab koj tuaj yeem tshem lub sib txuas.
Kauj ruam 6
Tso lub microcircuit rau hauv qhov chaw so, ua kom sov dua mus rau 300 degrees, thaum koj hnov ntxhiab tsw ntawm cov yam ntxwv ntawm qhov sib txuas, coj ib qho spatula thiab ntxuav nws cov khoom seem ntawm microcircuit. Ua txhua yam yeeb yam kom zoo zoo thiaj li tsis ua kev puas tsuaj rau Circuit Court.
