MuPCBkusangana uye kushambadzira maitiro, SMT chip processing vagadziri vane vashandi vazhinji kana vatengi vanobatanidzwa mukushanda, sekunge plug-in kuisa, ICT kuyedza, PCB kupatsanura, bhuku PCB solder mashandiro, screw mounting, rivet mounting, crimp connector manual pressing, PCB bhasikoro, nezvimwewo, iyo inonyanya kushanda ndeye munhu mumwe chete anotora bhodhi neruoko rumwe, iyo inonyanya kukosha mukukundikana kweBGA uye chip capacitors. Saka nei izvi zvichikonzera kusashanda zvakanaka? Rega mupepeti wedu akutsanangurire nhasi!
Njodzi dzekubataPCBbhodhi neruoko rumwe:
(1) Kubata bhodhi rePCB neruoko rumwe kunowanzobvumidzwa kune aya mabhodhi edunhu ane saizi diki, huremu huremu, pasina BGA uye pasina chip kugona; asi kune iwo maseketi ane hukuru hukuru, huremu hunorema, BGA uye chip capacitors pamabhodhi eparutivi, izvo zvinofanirwa kudziviswa. Nekuti iyi mhando yemafambiro inogona kukonzera zviri nyore kuti majoini ekutengesa eBGA, chip capacitance uye kunyangwe chip kuramba kukundikana. Nokudaro, mugwaro rekuita, zvinodiwa zvekutora bhodhi redunhu zvinofanira kuratidzwa.
Chikamu chakareruka chekubata PCB neruoko rumwe ndeyekutenderera bhodhi kutenderera maitiro. Kungave kubvisa bhodhi kubva mubhandi rekutakura kana kuisa bhodhi, vanhu vazhinji vanotora tsika yekubata PCB neruoko rumwe chete vasingazive nekuti ndiyo inonyanya kunakira. Kana ruoko ruchisunga, namira radiator uye isa screws. Kuti upedze kuvhiya, unozoshandisa ruoko rumwe chete kushanda zvimwe zvinhu pabhodhi. Aya anoita seakajairika mashandiro anowanzovanza hombe dzemhando njodzi.
(2) Kuisa screws. Mune akawanda SMT chip mafekitori ekugadzirisa, kuitira kuchengetedza mutengo, tooling inosiiwa. Kana ma screws akaiswa paPCBA, izvo zviri kuseri kwePCBA zvinogara zvichiremara nekuda kwekusaenzana, uye zviri nyore kutsemura majoini ekutemesa-sensitive solder.
(3) Kuisa kuburikidza-gomba zvikamu
Kuburikidza ne-gomba zvikamu, kunyanya ma transformer ane makobvu anotungamira, anowanzo kunetsa kupinza nemazvo mumakomba anokwira nekuda kwenzvimbo yakakura kushivirira kweanotungamira. Vashandi havazoedzi kutsvaga nzira yekuve yakarurama, kazhinji vachishandisa yakaomesesa-inoshanda, izvo zvinokonzeresa kukotama uye deformation yePCB board, uye zvinokonzeresa kukuvadza kune yakatenderedza chip capacitors, resistors, uye BGA.
