ntawm no yog kub thiab tooj liab nyob rau hauv Circuit Court boards ntawm lub xov tooj ntawm tes thiab computers. Yog li ntawd, tus nqi rov ua dua ntawm cov khoom siv hluav taws xob tuaj yeem ncav cuag ntau dua 30 yuan ib kilogram. Nws yog kim dua li muag cov ntawv pov tseg, iav fwj, thiab cov khoom seem hlau.

Los ntawm sab nraud, txheej txheej ntawm lub rooj tsav xwm Circuit Court feem ntau muaj peb xim: kub, nyiaj, thiab lub teeb liab. Kub yog qhov kim tshaj plaws, nyiaj yog qhov pheej yig tshaj, thiab lub teeb liab yog qhov pheej yig tshaj.

Nws tuaj yeem pom los ntawm cov xim seb lub chaw tsim khoom kho vajtse puas tau txiav cov fab. Tsis tas li ntawd, sab hauv ntawm lub rooj tsav xwm hauv Circuit Court yog cov tooj liab ntshiab, uas yooj yim oxidized yog tias raug huab cua. Cov txheej txheej sab nrauv yuav tsum muaj cov txheej txheem tiv thaiv saum toj no. Ib txhia neeg hais tias golden daj yog tooj liab, uas yog tsis ncaj ncees lawm.

Golden:

Cov kub uas kim tshaj plaws yog kub tiag. Txawm hais tias tsuas muaj txheej nyias nyias, nws kuj suav txog ze li 10% ntawm tus nqi ntawm lub rooj tsavxwm. Qee qhov chaw raws ntug dej hiav txwv ntawm Guangdong thiab Fujian tshwj xeeb hauv kev yuav khoom pov tseg Circuit Court boards thiab tshem tawm cov kub. Cov nyiaj tau los ntau heev.

Muaj ob qho laj thawj vim li cas siv kub, ib qho yog los pab kev vuam, thiab lwm yam yog tiv thaiv corrosion.

Cov ntiv tes kub ntawm lub cim xeeb module 8 xyoo dhau los tseem ci, yog tias koj hloov nws mus rau tooj liab, txhuas, lossis hlau, nws yuav xeb thiab tsis muaj txiaj ntsig.

Cov txheej kub-plated yog dav siv nyob rau hauv cov khoom pads, kub ntiv tes, thiab connector shrapnel ntawm lub Circuit Court board.
Yog tias koj pom tias qee lub rooj tsav xwm hauv Circuit Court yog nyiaj tag nrho, koj yuav tsum tau txiav cov ces kaum. Lub sij hawm kev lag luam hu ua "costdown".

Lub xov tooj ntawm tes motherboards feem ntau yog kub-plated boards, thaum lub computer motherboards, suab thiab me me digital circuit boards feem ntau tsis kub-plated boards.

Nyiaj
Puas yog aureate ib qho kub thiab nyiaj ib qho nyiaj?
Tau kawg tsis yog, nws yog tin.

Lub board nyiaj yog hu ua spray tin board. Txau ib txheej ntawm cov tin rau ntawm txheej txheej ntawm tooj liab tuaj yeem pab tau soldering. Tab sis nws tsis tuaj yeem muab kev sib cuag mus ntev xws li kub.

Cov tshuaj tsuag tin phaj tsis muaj kev cuam tshuam rau cov khoom siv uas tau raug soldered, tab sis qhov kev ntseeg tau tsis txaus rau cov ntaub qhwv uas tau raug huab cua ntev ntev, xws li cov ntaub qhwv hauv av thiab lub caij nplooj ntoos hlav pins. Kev siv lub sij hawm ntev yog qhov ua rau oxidation thiab corrosion, uas ua rau kev sib cuag tsis zoo.

Lub rooj sib tham ntawm cov khoom siv digital me me, yam tsis muaj kev zam, yog cov tshuaj tsuag tin boards. Tsuas muaj ib qho laj thawj xwb: pheej yig.

Cov khoom lag luam me me nyiam siv cov tshuaj tsuag tin phaj.

Lub teeb liab:
OSP, organic soldering zaj duab xis. Vim nws yog cov organic, tsis yog hlau, nws yog pheej yig dua tin spraying.

Lub luag haujlwm ntawm cov yeeb yaj kiab no tsuas yog los xyuas kom meej tias cov ntawv ci tooj liab sab hauv yuav tsis raug oxidized ua ntej vuam. Cov txheej ntawm zaj duab xis evaporates sai li sai tau thaum nws yog rhuab thaum vuam. Lub solder tuaj yeem txuas cov hlau tooj liab thiab cov khoom ua ke.

Tab sis nws tsis yog resistant rau corrosion. Yog tias lub rooj tsav xwm OSP raug huab cua rau kaum hnub, nws yuav tsis tuaj yeem vuam cov khoom.

Ntau lub khoos phis tawj motherboard siv OSP thev naus laus zis. Vim tias thaj tsam ntawm lub rooj tsav xwm Circuit Court loj dhau, nws tsis tuaj yeem siv rau kub plating.
