High precision PCBA Circuit Board DIP plug-in xaiv yoj soldering vuam tsim yuav tsum ua raws li qhov yuav tsum tau ua!
Nyob rau hauv cov txheej txheem kev siv hluav taws xob ib txwm siv, yoj vuam tshuab feem ntau yog siv rau kev vuam ntawm cov ntawv luam tawm cov khoom siv nrog perforated ntxig cov ntsiab lus (PTH).
DIP yoj soldering muaj ntau qhov tsis zoo:
1. High-density, nplua-pitch SMD Cheebtsam tsis tuaj yeem muab faib rau ntawm qhov chaw vuam;
2. Muaj ntau txoj kev txuas thiab tsis muaj vuam;
3.Flux yuav tsum tau txau; cov ntawv luam tawm yog warped thiab deformed los ntawm ib tug loj thermal shock.
Raws li tam sim no Circuit Court sib dhos ceev tau nce siab dua thiab siab dua, nws yog ib qho inevitable uas high-density, nplua-pitch SMD Cheebtsam yuav muab faib rau ntawm soldering nto. Cov txheej txheem nthwv dej ib txwm muaj tsis muaj zog los ua qhov no. Feem ntau, SMD Cheebtsam ntawm qhov chaw soldering tuaj yeem tsuas yog reflow soldered nyias. , thiab tom qab ntawd manually kho cov txuas txuas ntxiv txuas ntxiv, tab sis muaj teeb meem ntawm cov khoom siv tsis zoo sib xws.
Raws li cov khoom siv los ntawm lub qhov (tshwj xeeb tshaj yog muaj peev xwm loj lossis cov khoom zoo-pitch) ua ntau thiab nyuaj, tshwj xeeb tshaj yog rau cov khoom uas tsis muaj hlau lead thiab muaj kev ntseeg siab, cov khoom zoo ntawm phau ntawv soldering tsis tuaj yeem ua tau zoo dua. khoom siv hluav taws xob. Raws li cov kev xav tau ntawm kev tsim khoom, yoj soldering tsis tuaj yeem ua tau raws li kev tsim khoom thiab kev siv cov khoom me me thiab ntau yam hauv kev siv tshwj xeeb. Daim ntawv thov ntawm kev xaiv yoj soldering tau tsim sai heev nyob rau hauv xyoo tas los no.
Rau PCBA Circuit Court boards uas tsuas yog THT perforated Cheebtsam, vim hais tias yoj soldering tshuab tseem yog txoj kev ua tau zoo tshaj plaws nyob rau tam sim no, nws tsis tsim nyog los hloov yoj soldering nrog xaiv soldering, uas yog ib qho tseem ceeb heev. Txawm li cas los xij, kev xaiv soldering yog qhov tseem ceeb rau cov tshuab sib xyaw ua ke thiab, nyob ntawm seb hom nozzle siv, cov txheej txheem yoj soldering tuaj yeem rov ua dua hauv qhov zoo nkauj.
Muaj ob txoj kev sib txawv rau kev xaiv soldering: luag soldering thiab dip soldering.
Cov txheej txheem xaiv drag soldering yog ua tiav ntawm ib qho me me ntsis solder yoj. Cov txheej txheem rub soldering yog tsim rau soldering ntawm qhov chaw nruj heev ntawm PCB. Piv txwv li: ib tug neeg solder pob qij txha los yog pins, ib kab ntawm cov pins tuaj yeem raug rub thiab soldered.
Selective yoj soldering technology yog ib tug tshiab tsim technology nyob rau hauv SMT technology, thiab nws zoo nkaus li ua tau raws li qhov yuav tsum tau los ua ke ntawm high-density thiab ntau yam sib xyaw PCB boards. Selective yoj soldering muaj qhov zoo ntawm kev ywj pheej ntawm kev sib koom ua ke tsis sib xws, tsis tshua muaj thermal shock rau PCB, tsis tshua muaj dej txau, thiab muaj zog soldering kev ntseeg tau. Nws yog maj mam dhau los ua ib qho tseem ceeb ntawm kev siv thev naus laus zis rau cov PCBs nyuaj.
Raws li peb txhua tus paub, PCBA Circuit Board tsim theem txiav txim siab 80% ntawm cov nqi tsim khoom ntawm cov khoom. Ib yam li ntawd, ntau tus yam ntxwv zoo raug kho thaum lub sijhawm tsim. Yog li ntawd, nws yog ib qho tseem ceeb heev uas yuav tsum xav txog kev tsim khoom hauv PCB Circuit Board tsim txheej txheem.
DFM zoo yog txoj hauv kev tseem ceeb rau PCBA mounting tivthaiv cov tuam txhab kom txo qis kev tsim khoom, ua kom yooj yim rau kev tsim khoom, txo lub voj voog tsim, txo cov nqi tsim khoom, txhim kho kev tswj kom zoo, txhim kho cov khoom lag luam kev sib tw, thiab txhim kho cov khoom lag luam kev ntseeg siab thiab kav ntev. Nws tuaj yeem pab cov lag luam kom tau txais txiaj ntsig zoo tshaj plaws nrog kev nqis peev tsawg thiab ua tiav ob zaug qhov txiaj ntsig nrog ib nrab ntawm kev siv zog.
Kev txhim kho ntawm cov khoom siv saum npoo av mus rau niaj hnub no xav kom SMT engineers tsis yog tsuas yog yuav tsum tau paub zoo hauv Circuit Board tsim thev naus laus zis, tab sis kuj tseem yuav tsum muaj kev nkag siab tob thiab kev ua tau zoo hauv SMT thev naus laus zis. Vim tias tus tsim qauv uas tsis nkag siab txog cov yam ntxwv ntawm cov tshuaj nplaum thiab cov khoom siv feem ntau nyuaj rau kev nkag siab txog cov laj thawj thiab cov hauv paus ntsiab lus ntawm kev sib txuas, tipping, tombstone, wicking, thiab lwm yam, thiab nws yog ib qho nyuaj rau kev ua hauj lwm nyuaj los tsim cov qauv ntaub ntawv kom tsim nyog. Nws yog ib qho nyuaj rau daws nrog ntau yam teeb meem tsim los ntawm qhov kev xav ntawm kev tsim khoom tsim, kev sim, thiab kev txo nqi thiab kev siv nyiaj. Ib qho kev daws teeb meem zoo kawg nkaus yuav raug nqi ntau ntawm kev tsim khoom thiab kuaj cov nqi yog tias DFM thiab DFT (tsim rau kev kuaj pom) tsis zoo.
