Peb feem ntau ntsib cov neeg pluag BGA soldering nyob rau hauv cov txheej txheem ntawm PCB los ua ke txheej txheem vim tsis tsim PCB tsim nyob rau hauv lub chaw ua hauj lwm.Yog li ntawd, PCBFuture yuav ua cov ntsiab lus thiab qhia txog ntau qhov teeb meem tsim qauv thiab kuv vam tias nws tuaj yeem muab cov kev xav zoo rau PCB cov neeg tsim khoom!
Feem ntau muaj cov phenomena hauv qab no:
1. Cov vias hauv qab ntawm BGA tsis ua tiav.
Muaj los ntawm qhov nyob rau hauv BGA ncoo, thiab cov pob solder ploj nrog lub solder thaum lub sij hawm soldering;Kev tsim PCB tsis siv cov txheej txheem ntawm lub npog ntsej muag, thiab ua rau poob ntawm cov khoom siv thiab cov khoom siv los ntawm cov vias uas nyob ib sab ntawm lub ncoo, ua rau cov pob qij txha ploj, raws li pom hauv daim duab hauv qab no.
2.BGA solder mask yog tsim tsis zoo.
Qhov kev tso kawm ntawm qhov ntawm lub PCB pads yuav ua rau solder poob;Kev sib dhos PCB siab ceev yuav tsum tau txais cov microvia, dig muag vias lossis ntsaws cov txheej txheem kom tsis txhob muaj qhov poob;Raws li pom hauv daim duab hauv qab no, nws siv yoj soldering, thiab muaj vias nyob hauv qab ntawm BGA.Tom qab yoj soldering, lub vuam ntawm lub vias cuam tshuam rau kev ntseeg siab ntawm BGA soldering, ua rau muaj teeb meem xws li luv luv Circuit Court ntawm cov khoom.
3. BGA pad tsim.
Cov hlau lead ntawm BGA ncoo yuav tsum tsis pub tshaj 50% ntawm txoj kab uas hla ntawm lub ncoo, thiab cov hlau lead ntawm lub hwj huam mov yuav tsum tsis pub tsawg dua 0.1 hli, thiab tom qab ntawd ua kom tuab.Txhawm rau tiv thaiv kom tsis txhob deformation ntawm lub ncoo, lub qhov rais lub qhov ncauj qhov ntswg yuav tsum tsis txhob loj dua 0.05mm, raws li qhia hauv daim duab hauv qab no.
4.Qhov loj ntawm PCB BGA ncoo tsis yog tus qauv thiab nws loj dhau lossis me dhau, raws li qhia hauv daim duab hauv qab no.
5. Cov ntaub qhwv BGA muaj qhov sib txawv, thiab cov pob qij txha yog cov voj voog tsis sib xws ntawm ntau qhov sib txawv, raws li qhia hauv daim duab hauv qab no.
6. Qhov kev ncua deb ntawm BGA thav duab kab thiab ntug ntawm lub cev tivthaiv yog ze heev.
Txhua qhov chaw ntawm cov khoom siv yuav tsum nyob rau hauv cov cim ntau yam, thiab qhov kev ncua deb ntawm kab kab thiab ntug ntawm cov khoom siv yuav tsum yog ntau tshaj 1/2 ntawm qhov kawg ntawm qhov loj ntawm cov khoom, raws li qhia hauv daim duab hauv qab no.
PCBFuture yog cov kws tshaj lij PCB & PCB sib dhos cov chaw tsim khoom uas tuaj yeem muab nrog PCB tsim, PCB sib dhos thiab cov kev pabcuam khoom.Qhov zoo tshaj plaws kev ruaj ntseg system thiab ntau yam kev soj ntsuam equipments pab peb los saib xyuas tag nrho cov txheej txheem ntau lawm, kom ruaj ntseg ntawm cov txheej txheem no thiab cov khoom zoo, lub caij no, cov cuab yeej siv siab heev thiab cov txheej txheem thev naus laus zis tau qhia kom tau txais kev txhim kho.
