1. PCB Kev kho saum npoo:

Anti-oxidation, tin spray, txhuas-dawb tin spray, immersion kub, immersion tin, immersion nyiaj, nyuaj kub plating, tag nrho cov board kub plating, kub ntiv tes, npib tsib xee palladium kub OSP: qis nqi, zoo solderability, hnyav cia tej yam kev mob, lub sij hawm. Luv luv, environmentally friendly technology, zoo vuam thiab du.

Spray tin phaj yog feem ntau yog multilayer (4-46 txheej) high-precision PCB qauv, uas tau siv los ntawm ntau yam kev sib txuas lus hauv tsev loj, khoos phis tawj, khoom siv kho mob thiab chaw lag luam aerospace thiab kev tshawb fawb. Golden ntiv tes (txuas ntiv tes) yog qhov sib txuas ntawm lub cim xeeb bar thiab lub cim xeeb qhov, tag nrho cov teeb liab kis tau los ntawm cov ntiv tes golden.

Cov ntiv tes kub yog tsim los ntawm ntau cov xim daj daj conductive. Vim hais tias saum npoo yog kub-plated thiab cov conductive contacts yog teem li ntiv tes, nws yog hu ua “golden ntiv tes”.

Cov ntiv tes kub yog coated nrog ib txheej ntawm kub ntawm cov tooj liab clad board los ntawm ib tug tshwj xeeb txheej txheem, vim hais tias kub yog heev resistant rau oxidation thiab muaj zog conductivity.

Txawm li cas los xij, vim yog tus nqi siab ntawm kub, feem ntau ntawm lub cim xeeb yog tam sim no hloov los ntawm tin plating. Txij li thaum xyoo 1990, cov ntaub ntawv tin tau nrov. Tam sim no, “golden ntiv tes” ntawm motherboards, nco thiab graphics phaib yuav luag txhua tus siv. Cov khoom siv Tin, tsuas yog ib feem ntawm cov ntsiab lus ntawm kev ua haujlwm siab ntawm cov servers / chaw ua haujlwm yuav txuas ntxiv ua kub-plated, uas yog ib txwm kim.

2. Vim li cas thiaj siv cov phaj kub-plated

Raws li qib kev sib koom ua ke ntawm IC nce siab thiab siab dua, IC pins ua ntau dua. Cov txheej txheem ntsug tin yog qhov nyuaj rau flatten cov ntaub nyias nyias, uas ua rau muaj teeb meem rau qhov chaw ntawm SMT; Tsis tas li ntawd, lub txee lub neej ntawm cov tshuaj tsuag tin phaj yog luv heev.

Lub rooj tsavxwm kub-plated tsuas yog daws cov teeb meem no:

1. Rau cov txheej txheem mounting nto, tshwj xeeb tshaj yog rau 0603 thiab 0402 ultra-me me nto mounts, vim hais tias lub flatness ntawm lub ncoo yog ncaj qha cuam tshuam rau qhov zoo ntawm solder paste printing txheej txheem, nws muaj ib tug txiav txim siab ntawm qhov zoo ntawm lub tom ntej reflow. soldering, yog li tag nrho board Kub plating yog muaj nyob rau hauv high-density thiab ultra-me me nto mount txheej txheem.

2. Nyob rau hauv lub sij hawm mus sib hais ntau lawm, vim muaj tej yam xws li tivthaiv procurement, feem ntau tsis yog hais tias lub rooj tsavxwm yog soldered tam sim ntawd thaum nws los txog, tab sis nws yog feem ntau siv rau ob peb lub lis piam los yog txawm lub hlis. Lub txee lub neej ntawm lub rooj tsavxwm kub-plated yog zoo dua li cov hlau lead. Tin alloy yog ntau zaus ntev dua, yog li txhua tus neeg zoo siab siv nws.

Tsis tas li ntawd, tus nqi ntawm kub-plated PCB nyob rau hauv cov qauv theem yog yuav luag tib yam li cov hlau lead-tin alloy board.

Tab sis raws li cov xov hluav taws xob ua denser, kab dav thiab qhov sib txawv tau mus txog 3-4MIL.

Yog li ntawd, qhov teeb meem ntawm kub hlau luv luv Circuit Court yog coj: raws li qhov zaus ntawm lub teeb liab yuav siab dua thiab siab dua, cov teeb liab kis tau tus mob nyob rau hauv multi-plated txheej tshwm sim los ntawm cov nyhuv ntawm daim tawv nqaij muaj kev cuam tshuam rau cov teeb liab zoo.

Cov nyhuv ntawm daim tawv nqaij yog hais txog: siab zaus alternating tam sim no, lub tam sim no yuav nyiam mloog nyob rau saum npoo ntawm cov hlau ntws. Raws li kev suav, qhov tob ntawm daim tawv nqaij yog cuam tshuam nrog zaus.

Txhawm rau daws cov teeb meem saum toj no ntawm cov laug cam kub, PCBs siv cov boards kub plated feem ntau muaj cov yam ntxwv hauv qab no:

1. Vim hais tias cov qauv siv lead ua tsim los ntawm immersion kub thiab kub plating yog txawv, immersion kub yuav golden yellower dua kub plating, thiab cov neeg muas zaub yuav txaus siab rau.

2. Immersion kub yog yooj yim rau weld dua kub plating, thiab yuav tsis ua rau vuam tsis zoo thiab ua rau cov neeg tsis txaus siab.

3. Vim hais tias lub immersion kub board tsuas muaj npib tsib xee thiab kub ntawm lub ncoo, lub teeb liab kis tau tus mob nyob rau hauv daim tawv nqaij nyhuv yuav tsis cuam tshuam rau lub teeb liab ntawm txheej tooj liab.

4. Vim tias immersion kub muaj cov qauv siv lead ua denser dua kub plating, nws tsis yooj yim los tsim oxidation.

5. Vim tias lub immersion kub board tsuas muaj npib tsib xee thiab kub ntawm cov ntaub qhwv, nws yuav tsis tsim cov xov kub kub thiab ua rau me ntsis luv.

6. Vim hais tias lub immersion kub board tsuas muaj npib tsib xee thiab kub ntawm lub ncoo, solder daim npog qhov ncauj nyob rau hauv lub Circuit Court thiab cov tooj liab txheej yog ruaj khov.

7. Qhov project yuav tsis cuam tshuam qhov kev ncua deb thaum them nyiaj.

8. Vim hais tias cov qauv siv lead ua tsim los ntawm immersion kub thiab kub plating yog txawv, qhov kev nyuaj siab ntawm immersion kub phaj yog yooj yim los tswj, thiab rau cov khoom uas muaj kev sib raug zoo, nws yog ntau conducive rau bonding ua. Nyob rau tib lub sij hawm, nws yog precisely vim hais tias lub immersion kub yog softer tshaj gilding, yog li lub immersion kub phaj tsis hnav-resistant li tus ntiv tes kub.

9. Lub flatness thiab stand-by lub neej ntawm immersion kub board yog zoo li lub rooj tsavxwm kub-plated.

Rau cov txheej txheem gilding, cov nyhuv ntawm tinning yog heev txo, thaum lub tinning nyhuv ntawm immersion kub yog zoo dua; tshwj tsis yog tias cov chaw tsim khoom xav tau kev khi, feem ntau cov tuam txhab tam sim no yuav xaiv cov txheej txheem immersion kub, uas feem ntau tshwm sim hauv qhov xwm txheej, kev kho mob ntawm PCB yog raws li hauv qab no:

Kub plating (electroplating kub, immersion kub), nyiaj plating, OSP, tin spraying (ua thiab lead-dawb).

Cov hom no feem ntau yog rau FR-4 lossis CEM-3 thiab lwm lub rooj tsavxwm. Cov ntaub ntawv hauv paus thiab txoj kev kho saum npoo ntawm rosin txheej; Yog hais tias lub tin tsis zoo (tsis zoo tin noj), yog tias cov tshuaj txhuam hniav thiab lwm cov chaw tsim khoom raug tshem tawm vim yog vim li cas ntawm cov khoom siv thiab cov khoom siv technology.

Ntawm no tsuas yog rau cov teeb meem PCB, muaj cov laj thawj hauv qab no:

1. Thaum lub sij hawm PCB luam ntawv, seb puas muaj roj-permeable zaj duab xis nto ntawm lub PAN txoj hauj lwm, uas tuaj yeem thaiv cov nyhuv ntawm tinning; qhov no tuaj yeem txheeb xyuas tau los ntawm kev sim tshuaj tin bleaching.

2. Txawm hais tias lub lubrication txoj hauj lwm ntawm PAN txoj hauj lwm ua tau raws li qhov yuav tsum tau ua, uas yog, seb qhov kev txhawb nqa ntawm cov khoom tuaj yeem lav tau thaum lub sij hawm tsim ntawm lub ncoo.

3. Txawm hais tias lub ncoo muaj paug, qhov no tuaj yeem tau txais los ntawm ion pollution test; peb lub ntsiab lus saum toj no yog qhov tseem ceeb hauv kev txiav txim siab los ntawm PCB cov tuam txhab.

Hais txog qhov zoo thiab qhov tsis zoo ntawm ntau txoj hauv kev ntawm kev kho saum npoo, txhua tus muaj nws tus kheej qhov zoo thiab qhov tsis zoo!

Hais txog kev kub plating, nws tuaj yeem khaws cov PCBs rau lub sijhawm ntev dua, thiab muaj kev hloov pauv me me ntawm qhov kub thiab av noo ntawm ib puag ncig sab nraud (piv rau lwm qhov kev kho deg), thiab feem ntau tuaj yeem khaws cia txog li ib xyoos; Kev kho cov tin-txhaj tshuaj yog qhov thib ob, OSP dua, qhov no ntau ntawm kev mloog yuav tsum tau them rau lub sijhawm cia ntawm ob qhov chaw kho mob ntawm qhov kub thiab txias.

Nyob rau hauv ib txwm muaj xwm txheej, kev kho deg ntawm immersion nyiaj yog qhov sib txawv me ntsis, tus nqi kuj tseem siab, thiab cov kev cia khoom xav tau ntau dua, yog li nws yuav tsum tau ntim rau hauv daim ntawv tsis muaj leej faj! Thiab lub sijhawm cia yog li peb lub hlis! Nyob rau hauv cov nqe lus ntawm cov nyhuv ntawm tinning, immersion kub, OSP, tin spraying, thiab lwm yam yog tiag tiag tib yam, thiab manufacturers mas xav txog nqi-zoo!
