Peb rov kho cov tshuab hauv nruab nrab cov nqi uas siv cov PLC thiab lub sijhawm siv mus txuas rau hauv microcontrollers tsim los ua huab hwm coj cov nqi qis.
2. Qhia cov ntaub ntawv
Uniwell Circuits Co., Ltd, yog ib tug PCB kev tsim khoom lag luam, peb muaj 2 cog nroj tsuag, Shenzhen founded hauv lub Plaub Hlis, 2007 Tuam Tshoj. Jiangmen Hoobkas tau pom nyob rau hauv 2010. 600 tus neeg ua hauj lwm nyob rau hauv tag nrho, ua ke Shenzhen thiab Jiangmen Hoobkas Uniwell Circuits muaj peev xwm ua tau 100,000 square taw ntawm 2-40 txheej PCBs thiab delivering tshaj 5000 ntau yam. Koj yuav paub ntau ntxiv txog Uniwell los ntawm cov video, Peb xav kom koj ua tus khub ntev hauv Suav.
3.Koj puas paub koj qhov kev kho PCB?
Feem ntau cov kev kho PCB feem ntau yog raws li nram no:
1) Kub kub
Nruab nrab ntawm OSP thiab electrolessess nickel / dip, cov txheej txheem yog yooj yim thiab ceev.Yuav ua kom kub, av thiab qhov muaj kuab paug tuaj yeem npaj muaj hluav taws xob zoo thiab zoo weldability, tab sis yuav poob luster.Vim li ntawd, yog tsis muaj cov xim nickel nyob hauv cov nyiaj txheej, nws tsis muaj tag nrho cov zoo lub cev muaj zog ntawm electrolesses nickel / leaching.
2) Nickel plating
Nyob rau ntawm PCB, ib txheej ntawm nickel yog tso rau ntawm tus neeg xyuas pib, thiab cov nickel plating mas kom tiv thaiv kis ntawm kub thiab tooj liab.Tam muaj ob hom electriclating nickel kub: muag kub kub plating (kub , kub tsis zoo nkauj) thiab tawv kub plating, qhov chaw du, tawv, hnav-resisting, muaj cobalt thiab lwm cov ntsiab, qhov saum npoo zoo dua lub teeb) .Txhua kub kub yog siv rau ntim ntim kub hlau; Lub zog kub tsuas yog siv rau hluav taws xob interconnections hauv cov chaw tsis yog vuam (eg, goldfinger).
3) PCB tov tshuaj kho tshuab.
Xaiv ob los yog ntau tshaj ob hom kev kho mob, qhov kev kho mob ntawm ntau hom tshuaj muaj xws li: kub nickel kub + anti-oxidation, kub + nickel plating nickel, plating nickel kub + kub cua leveling, hnyav nickel kub + kub cua leveling.
Tag nrho cov kev kho ntom ntws yog qhov ntau tshaj thiab pheej yig tshaj rau kev kub ntxhov (lead-free / lead), tiam sis thov nco ntsoov cov cai ntawm eH RoHS.
4) Cov cua kub kub.
Cov txheej txheem ntawm txheej hlau yajthem ua hmoov txhuas ntawm lub PCB thiab cua sov cua txias (tshuab raj nplaum) rau ib txheej uas muaj peev xwm tiv thaiv tooj liab oxidation thiab muab lub voos zoo zoo. Cov laug thiab tooj yog tsim hauv qhov kev sib txuas ntawm cov cua kub cua thiab lub tooj liab yog tsim nyob rau hauv lub sib koom tes, thiab lub thickness yog txog 1 ~ 2mil.
5) Los tiv thaiv oxidation (OSP)
Nyob rau ntawm lub hauv paus ntawm lub hauv paus liab qab, ib txheej ntawm cov tawv nqaij yog zus ntawm cov tshuaj hauv paus. Qhov yeeb yaj kiab no muaj kev tiv thaiv oxidation, thermal shock thiab noo noo, uas tuaj yeem tiv thaiv qhov xuab zeb ntawm xeb (oxidation los yog vulcanization) hauv qhov chaw ib puag ncig. Nyob rau tib lub sijhawm, nws yuav tsum raug muab tshem tawm yooj yim ntawm lub plhaub hauv qhov vuam tshuam txuas ntxiv rau vuam siv.
6) Tshuaj tso quav ntawm xee caj npab.
Ntawm qhov tooj liab, ib txheej tuab ntawm nickel-kub hlau uas zoo hluav taws xob muaj peev xwm tiv thaiv tau PCB rau ib lub sij hawm ntev ntev dua.Ua zoo li OSP, nws tsuas yog ib qho xeb thaiv kab mob, nws tuaj yeem siv lub sijhawm ntev ntawm PCB thiab ua tiav hluav taws xob kev ua tau zoo dua.Kom ntxiv, nws muaj kev cia siab ntawm lwm cov kev kho mob saum npoo.
Yog tias koj tsis paub tias qhov twg yog qhov tseem ceeb tshaj plaws rau koj tus PCB, thov tsis txhob yig peb cov kws kho mob, peb zoo siab pab koj.
