8.Kev paub txog

Board soldering yog dab tsi?

Circuit board, Circuit Court board, PCB board, pcb soldering technology Nyob rau hauv xyoo tas los no, kev loj hlob keeb kwm ntawm lub

electronics kev lag luam, nws yuav tsum tau muab sau tseg tias ib tug heev pom tseeb qauv yog reflow soldering tshuab. Hauv paus ntsiab lus, conven-

tional inserts kuj tseem tuaj yeem ua tau reflow soldered, uas feem ntau hu ua los ntawm lub qhov reflow soldering. Qhov a-

dvantage yog tias nws muaj peev xwm ua kom tiav tag nrho cov pob qij txha nyob rau tib lub sijhawm, txo cov nqi tsim khoom. Txawm li cas los xij,

Qhov kub thiab txias Cheebtsam txwv tsis pub siv cov reflow soldering, seb nws yog plug-in lossis SMD. Tom qab ntawd p-

soldering. Qhov no yuav yog txoj kev pheej yig thiab muaj txiaj ntsig los ua kom tiav cov kev sib txuas ntawm qhov seem ntxiv thiab yog f-

ully sib xws nrog rau yav tom ntej tsis muaj hlau lead.

patible nrog rau yav tom ntej tsis muaj hlau lead- soldering.

Cov yam ntxwv ntawm cov txheej txheem xaiv soldering tuaj yeem muab piv rau yoj soldering kom nkag siab txog cov txheej txheem.

ess yam ntxwv ntawm kev xaiv soldering. Qhov sib txawv tshaj plaws ntawm ob yog qhov qis ntawm t-

Nws PCB nyob rau hauv yoj soldering yog kiag li raus nyob rau hauv cov kua solder, thaum nyob rau hauv xaiv soldering, tsuas yog tej yam uas yog-

zoo li yog nyob rau hauv kev sib cuag nrog lub solder yoj. Txij li thaum PCB nws tus kheej yog qhov nruab nrab ntawm cov cua kub tsis zoo, nws tsis sov lub solder

cov pob qij txha uas yaj cov khoom uas nyob ib sab thiab cov chaw PCB thaum lub sij hawm soldering. Lub flux yuav tsum tau pre-coated ua ntej muag-

nplhaib. Piv rau yoj soldering, flux tsuas yog siv rau ib feem ntawm PCB kom tau soldered, tsis yog tag nrho PCB. Hauv ad-

dition, xaiv soldering tsuas yog haum rau soldering ntawm interposing Cheebtsam. Selective soldering yog ib qho ua tiav

tely tshiab txoj hauv kev, thiab kev nkag siab zoo ntawm cov txheej txheem thiab cov khoom siv yog qhov tsim nyog rau kev xaiv

soldering tau yooj yim.

Cov txheej txheem xaiv Soldering Cov txheej txheem xaiv cov txheej txheem muaj xws li: txheej txheej flux, PCB preheating, dip solderi-

ng, thiab luag soldering.

Flux txheej txheej txheem Nyob rau hauv cov txheej txheem xaiv soldering, cov txheej txheem flux txheej plays lub luag haujlwm tseem ceeb. Thaum kawg ntawm

solder cua sov thiab soldering, lub flux yuav tsum muaj txaus kom tiv thaiv bridging thiab tiv thaiv oxidation ntawm PCB.

Cov flux yog txau los ntawm X / Y neeg hlau nqa lub PCB los ntawm cov flux nozzle thiab cov flux yog txau mus rau PCB los ua

soldered. Fluxes muaj nyob rau hauv ib lub nozzle tsuag, micro-qhov tshuaj tsuag, thiab ib txhij multi-point / qauv tshuaj tsuag. Cov

microwave ncov tom qab cov txheej txheem reflow soldering, qhov tseem ceeb tshaj plaws yog qhov tseeb txau ntawm flux. Cov mi-

cro-qhov tshuaj tsuag hom yuav tsis kis kab mob rau thaj tsam sab nraud ntawm qhov sib koom ua ke. Yam tsawg kawg nkaus solder dot qauv txoj kab uas hla

ntawm micro-txhaj tshuaj yog ntau dua 2 hli, yog li qhov tseeb ntawm qhov chaw ntawm cov khoom tso rau ntawm PCB yog ± 0.5mm, yog li

xyuas kom meej tias cov flux ib txwm npog qhov chaw soldered. Kev kam rau siab ntawm cov tshuaj tsuag tshuaj tua kab yog muab los ntawm tus neeg muag khoom.

Kev siv flux tau teev tseg thiab 100 feem pua ​​​​ntawm kev tiv thaiv kev nyab xeeb feem ntau pom zoo.

Lub hom phiaj tseem ceeb ntawm cov txheej txheem preheating nyob rau hauv cov txheej txheem xaiv soldering tsis yog los txo cov thermal stress, tab sis rau

tshem tawm cov kuab tshuaj ua ntej ziab kom qhuav, kom cov flux muaj qhov tseeb viscosity ua ntej nkag mus rau hauv lub vuam yoj. Thaum ntawd-

ldering, cov nyhuv ntawm preheating cua sov ntawm solder zoo tsis yog ib qho tseem ceeb. PCB khoom thickness, ntaus pob loj,

thiab hom flux txiav txim siab qhov preheat kub qhov chaw. Hauv kev xaiv soldering, muaj qhov sib txawv theoretical piav qhia-

ons rau preheating: Qee tus txheej txheem engineers ntseeg tias PCB yuav tsum tau preheated ua ntej cov flux yog sprayed; lwm

point of view yog tias soldering tsis tas yuav tsum tsis muaj preheating. Tus neeg siv tuaj yeem npaj cov txheej txheem xaiv soldering ac-

cording rau qhov xwm txheej tshwj xeeb.
