PCBA processing inozivikanwawo se chip process, mamwe ekumusoro layer anonzi SMT processing, SMT processing, kusanganisira SMD, DIP plug-in, post-solder bvunzo uye mamwe maitiro, zita remapadhi harisi patin rinonyanya mu. SMD processing link, paste izere nezvinhu zvakasiyana-siyana zvebhodhi inoshanduka kubva kuPCB light board, pcb light board ine mapedhi akawanda (kuiswa kwezvinhu zvakasiyana-siyana), kuburikidza neburi (plug-in), mapadhi haasi tin. ikozvino kuitika Mamiriro acho mashoma, asi mu SMT mukati munewo kirasi yehutano matambudziko.
Matambudziko emhando yemhando, anosungirwa kuve akawanda zvikonzero, mune chaiyo yekugadzira maitiro, inofanirwa kuve yakavakirwa pane yakakodzera ruzivo kuti uone, imwe neimwe kugadzirisa, kutsvaga kwainobva dambudziko uye kugadzirisa.
I. Kuchengetwa kusina kunaka kwePCB
Kazhinji, kupfapfaidza tini pasvondo kuchaita oxidation, OSP yekurapa kwepamusoro inogona kuchengetwa kwemwedzi mitatu, ndiro yegoridhe yakanyura inogona kuchengetwa kwenguva yakareba (parizvino maitiro ekugadzira PCB akanyanya)
II.Kushanda kusina kunaka
Yakashata welding nzira, haina kukwana kupisa simba, kwete tembiricha yakakwana, isina kukwana reflow nguva uye mamwe matambudziko.
III.Iyo PCB dhizaini matambudziko
Solder pad uye nzira yekubatanidza ganda remhangura inotungamira mukusakwana pad kudziyisa.
IV.Dambudziko rekuyerera
Flux chiitiko hachina kukwana, PCB pads uye zvemagetsi zvikamu zvekutengesa zvishoma hazvibvise oxidation zvinhu, solder majoini bit flux haina kukwana, zvichikonzera kunyorova kwakashata, kuyerera kwetin poda haina kunyatso mutswa, kutadza kunyatsobatanidzwa mukuyerera. (solder paste kudzoka kune tembiricha nguva ipfupi)
V. PCB bhodhi pachayo dambudziko.
PCB bhodhi mufekitari pamberi pedhi pamusoro oxidation haina kurapwa
VI.Reflow ovhenimatambudziko
Preheating nguva ipfupi, tembiricha yakadzikira, tini harina kunyunguduka, kana preheating nguva yakarebesa, tembiricha yakawandisa, zvichikonzera kutadza kwekuita kweflux.
Kubva pane zvikonzero zviri pamusoro apa, PCBA kugadzirisa imhando yebasa haigone kuve yakapusa, nhanho imwe neimwe inoda kuve yakaoma, zvikasadaro pane huwandu hukuru hwezvinetso zvemhando muyedzo yewelding yekupedzisira, zvino zvinokonzeresa nhamba yakakura kwazvo yevanhu. kurasikirwa kwemari uye kwezvinhu, saka PCBA kugadzirisa pamberi pebvunzo yekutanga uye chidimbu chekutanga cheSMD chinodiwa.
