Yintoni inkqubo ye-SMT PCB Assembly?
Inkqubo yokusebenzisa i-SMT ukwenza izixhobo zePCB ibandakanya ukusetyenziswa koomatshini abazenzekelayo ukudibanisa amacandelo e-elektroniki.Lo matshini ubeka ezi zinto kwibhodi yesekethe, kodwa ngaphambi koko, ifayile ye-PCB kufuneka ihlolwe ukuze kuqinisekiswe ukuba abanazo iingxaki ezichaphazela ukwenziwa kunye nokusebenza kwesixhobo.Emva kokuqinisekisa ukuba yonke into ilungile, inkqubo yendibano ye-SMT PCB ayiphelelanga ekuthengiseni nasekubekeni izinto okanye iikhompawundi kwi-PCB.Le nkqubo ilandelayo yemveliso kufuneka nayo ilandelwe.
1. Faka i-solder paste
Inyathelo lokuqala xa udibanisa ibhodi ye-SMT PCB usebenzisa i-soldering paste.Intlama ingafakwa kwi-PCB ngeteknoloji yesikrini sesilika.Isenokusetyenziswa kusetyenziswa istencil yePCB elungiselelwe ukusuka kwifayile yemveliso yeCAD efanayo.Udinga kuphela ukusika i-stencils usebenzisa i-laser kwaye usebenzise i-soldering paste kwiindawo apho uya kuthengisa amacandelo.Ukusetyenziswa kwe-solder paste kufuneka kuqhutywe kwindawo epholileyo.Wakuba ugqibile ukufaka isicelo, unokulinda ixesha elithile lendibano.
2. Ukuhlolwa kwe-solder paste yakho
Emva kokuba i-solder paste isetyenziswe ebhodini, inyathelo elilandelayo kukuhlala uyijonga ngokusebenzisa iindlela zokuhlola i-solder paste.Le nkqubo ibaluleke kakhulu, ngakumbi xa uhlalutya indawo ye-solder paste, inani le-solder paste esetyenzisiweyo, kunye neminye imiba esisiseko.
3. Ukuqinisekiswa kwenkqubo
Nje ukuba ibhodi yakho yePCB isebenzisa amacandelo e-SMT nakweliphi na icala, kuya kubakho imfuneko yokuqwalasela ukuphinda inkqubo efanayo yokuqinisekiswa kwecala lesibini.uya kuba nakho ukulandelela elona xesha lifanelekileyo lokuveza incama ye-solder kubushushu begumbi apha.Oku kuxa ibhodi yakho yesekethe ilungele ukuhlanganiswa.Amacandelo aya kuhlala elungele umzi-mveliso olandelayo.
4. Iikhithi zeNdibano
Oku kuhambelana ne-BOM (iBill of Materials) esetyenziswa yi-CM ukuhlalutya idatha.Oku kuququzelela uphuhliso lweekiti zendibano ye-BOM.
5. Iikiti zokugcinwa kwempahla kunye nezinto
Sebenzisa ibhakhowudi ukuyikhupha kwisitokhwe kwaye uyifake kwikiti yendibano.Xa amacandelo efakwe ngokupheleleyo kwikhithi, athathwa asiwe kwindawo yokukhetha kunye nendawo ebizwa ngokuba yi-surface Mount technology.
6. Ukulungiswa kwamacandelo okubekwa
Isixhobo sokukhetha kunye nendawo siqeshwe apha ukubamba yonke into yokuhlanganisa.Lo matshini usebenzisa i-cartridge ehamba kunye neqhosha elikhethekileyo elihambelana ne-BOM kit assembly.Umatshini wenzelwe ukuxelela indawo ebanjwe yikhatriji.
