I. Stencil printer marudzi
A manual printer ndiyo yakapfava uye yakachipa inodhinda system.Kuiswa kwePCB uye kubviswa kunoitwa nemaoko, iyo squeegee inogona kushandiswa nemaoko kana kusungirirwa pamushini, uye chiito chekudhinda chinoitwa nemaoko.PCB uye simbi ndiro parallelism alignment kana mupendero webhodhi kuti ive nechokwadi chekuti chinzvimbo chinoenderana nehunyanzvi hwemushandisi, saka imwe neimwe yakadhindwa PCB, iyo inodhinda paramita inoda kugadziridzwa uye kuchinjwa.
2. Semi-otomatiki kudhinda muchina
Semi-automatic presses parizvino ndiyo inonyanya kushandiswa kudhinda michina, yakatonyanya kufanana nemichina yekutsikirira, kuiswa nekubviswa kwePCBs zvichiri kutsamira pakushanda kwemaoko, musiyano mukuru nemuchina wemawoko kugadzirwa kwemusoro wekudhinda, iwo. inogona kudzora zvirinani kumhanya kwekudhinda, squeegee pressure, squeegee angle, printing distance and non-contact pitch, maburi emidziyo kana PCB edges zvichiri kushandiswa kuisa, nepo simbi yeplate system yekubatsira vashandi Kuzadzikiswa kwakanaka kwePCB uye simbi plate parallelism kugadzirisa. .
3. Fully otomatiki kudhinda muchina
Iyo solder paste inodhindwa pamapadhi ezvikamu pabhodhi rekutanga, asi mazuva ano saizi yezvikamu zvakaiswa pamusoro-soro iri kuramba ichiderera, saka dhizaini yedhizaini base board inoenderana idiki uye yakanaka.Nokudaro, kunyatsoita uye kushanda kweiyo solder paste kudhinda kunofanira kuvandudzwa zvikuru.Mazuva ano, vazhinji vevagadziri vezvigadzirwa zvemagetsi vari kushandisa otomatiki kana kuti yakazara otomatiki solder paste kudhinda michina yekugadzira SMT zvigadzirwa, uye PCB kuiswa kunoitwa neyakagadzika-inotakura bhandi rekutakura, nemaitiro ekuita senge squeegee kumhanya, squeegee pressure, kudhinda kureba, uye. non-contact pitch zvese zvinorongwa.
PCB positioning inoitwa nekushandisa maburi ekuisa kana bhodhi micheto, uye mimwe midziyo inogona kushandisa masisitimu ekuona kuti ienderane nePCB nesimbi ndiro parallel kune imwe neimwe, izvo zvinobvisa kukanganisa kunokonzerwa nekumisikidza kumucheto kana uchishandisa masisitimu ekuona akadaro, uye inoita kuti chinzvimbo chive nyore, ine manual positioning simbiso inotsiviwa nemavision systems.Iwo matsva anodhinda paste maprinta ane vhidhiyo lenzi yekutarisa mamiriro ekudhinda uye kugadzirisa chero nguva.
II.Stencil printer kugadzirisa
Bvisa iyo squeegee, shandisa yakakosha yekupukuta pepa yakanyikwa muanhydrous ethanol, pukuta iyo squeegee yakachena, uye wozoiswa mumusoro wekudhinda kana kugamuchirwa mumudziyo wekushandisa.
Chenesa stencil, pane nzira mbiri.
Method 1: Washing machine kuchenesa.Kugeza michina ine template, iyo yekuchenesa mhedzisiro ndiyo yakanyanya kunaka.
Nzira 2:Kuchenesa nemaoko.
Shandisa yakakosha kupukuta bepa kuti uise anhydrous ethanol, iyo solder paste ichacheneswa, kana gomba rinoputika kuvhara, rinowanikwa nebhurasho remazino rakapfava, usabaya netsono yakaoma.
Shandisa pfuti yemhepo yakamanikidzwa kuridza zvakasara mugomba rekudonha retemplate rakachena.
Isa iyo template pamushini wekuisa paste, kana zvisakadaro ugamuchire mumudziyo wekushandisa.
