Hauv kev tsim covHigh-zaus cov pob tw, Kub plating thiab immersion kub cov txheej txheem kho kom zoo. Nws yog feem ntau siv nyob rau hauv kev tsim cov tsev loj-zaus, qhov chaw tiv thaiv kev tiv thaiv kev ua kom tiv thaiv oxidation thiab txhim kho kev ua haujlwm vawj tsev. Muaj ntau cov txheej txheem kev kho kom zoo rau cov pob tw siab, suav nrog kub plating cov txheej txheem muaj cov yam ntxwv sib txawv thiab cov xwm txheej sib txawv. Ntawm no, peb tsuas yog qhia ob txoj kev feem ntau: kub plating, immersion kub plating thiab wm.
Cov txheej txheem kev kho deg rau cov pab pawg siab ntau zaus: kub plating
Kub plating yog ib txoj kev ntawm kev tso ib txheej ntawm kub ntawm lub saum npoo ntawm tooj liab los ntawm cov hluav taws xob hauv tshuab hluav taws xob. Kub yog ib tug heev ruaj khov hlau uas tsis oxidize thiab muaj kev tiv thaiv lub siab zoo, yog li kub tiv thaiv tooj liab circuits thiab txhim kho kev ua kom zoo thiab siv nyiaj ntawm PCBs. Qhov zoo ntawm kub plating yog:
1. Kub Plated High-zaus cov pob tw tuaj yeem khaws cia ntev yog tsis muaj kev tiv thaiv lossis tsis zoo rau kev siv ntev lossis kev khaws cia.
2. Lub pob kub-plated high-zaus pawg tuaj yeem tuaj yeem tiv thaiv kom ntau yam tsis poob lossis deforming, ua rau kev kub siab rau ib puag ncig ua haujlwm siab.
3. Kub plated high-zaus txhim kho cov paib kev kis tau zoo, txo qis kev cuam tshuam rau lub teeb liab, kev kub ceev, thiab siab-precision transluits.

Sinking Kub yog ib txoj kev ntawm kev tso ib txheej ntawm kub ntawm lub saum npoo ntawm tooj liab los ntawm kev siv tshuaj lom neeg. Qhov sib txawv ntawm cov pob kub thiab kub plating yog tias kev tso nyiaj kub tsuas yog tso nyiaj kub nkaus xwb, nias kub plating rau tag nrho cov Circuit Court. Qhov zoo ntawm kev ntxuav kub muaj xws li:
1. Lub Circuit Court ntawm lub high-zaus ntawm sunk kub yog du thiab tsis muaj kev txhawj xeeb lossis kev cuam tshuam rau saum npoo mount thev naus laus zis thiab kev teeb tsa ntawm cov khoom siv micro.
2. Lub soldering kev ua tau zoo ntawm cov pawg loj yog qhov zoo dua vim tias cov khoom siv ua kom yooj yim dua vim tias cov khoom siv ua plees ua ke, thiab ua rau yooj yim dua vim tias cov nyiaj kub tso tawm yog qis dua li cov kub plating, ua rau nws tsis tshua ua rau britleness hauv cov pob qij txha sib dhos.
3. Lub teeb liab kis tau zoo ntawm cov kev lom zem-zaus nrog sunk kub yog vim tias sunk kub tsuas yog tsim cov xov hlau kub, txo txoj kev pheej hmoo ntawm kev ua txhaum.
Cov txheej txheem kev kho deg rau cov kev tsim cov tuam txhab ntau zaus: Opos
Cov tub ntxhais ntawm wm te ntawm kev sib sau ib zaj yeeb yaj kiab heev organic heev rau saum npoo ntawm PCB. Cov yeeb yaj kiab no muaj xws li cov tshuaj organic tshwj xeeb uas tuaj yeem hnov mob nrog cov tooj liab saum npoo los ua cov txheej tiv thaiv tsuas yog ob peb atoms tuab. Qhov kev tiv thaiv zaj duab xis tsis tsuas yog cuam tshuam tooj liab saum npoo oxidation, tab sis kuj tswj hwm nws cov solderability zoo.
Qhov zoo ntawm EOST:
1. Hood jonedability: osp zaj yeeb yaj kiab tuaj yeem tiv thaiv kev sib tw saum npoo oxidation ntawm pcb, yog li ua kom cov pcb ntawm pcb thaum lub sij hawm soldering.
2. Tus nqi qis: piv rau lwm cov txheej txheem khoos kom zoo li hluav taws xob kub, electroless npib kub, thiab lwm yam.
3. Yooj yim rau kev khiav lag luam: Cov txheej txheem wm yog qhov yooj yim thiab tsis tas yuav tsum muaj cov khoom siv nyuaj lossis cov txheej txheem ua haujlwm.
4. Ib puag ncig tus phooj ywg: wm act tsis muaj cov tshuaj phem thiab yog ib puag ncig phooj ywg.
5. Kev tshem tawm muaj zog: tsis zoo li qee cov txheej txheem kho cov txheej txheem kev kho kom zoo, ram ack tso cai rau kev ua haujlwm thiab kho cov pob qij txha sib dhos.
6. Kev ntsuam xyuas zoo heev thiab sib xyaw: wm tshuab muab kev sib cuag tsis zoo rau ICT (online kuaj), kom paub qhov tseeb ntawm kev xeem.
