Niaj hnub no, SMT (nto mount) thev naus laus zis tsis tuaj yeem sib cais los ntawm cov khoom siv tseem ceeb yog solder paste, uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho sai ntawm cov txheej txheem chip.
Lub luag haujlwm ntawm solder paste
Tin paste, raws li lub npe qhia, yog ib yam khoom zoo li paste, zoo ib yam li peb cov tshuaj txhuam hniav, nws lub luag hauj lwm yog los ntawm lub tshuab luam ntawv muab tshuaj txhuam yuav muab luam tawm rau pcb pad to saum toj no, nyob rau hauv lub mounting ntawm cov khoom ua si lub luag hauj lwm nplaum. nyob rau hauv kev tiv thaiv lub mounting ntawm lub Cheebtsam thiab kis tau tus mob ntawm kev co thiab ua rau lub Cheebtsam tawm ntawm txoj hauj lwm los yog poob. Nyob rau hauv lub reflow soldering thaum thawj kub yaj thiaj li hais tias qhov chaw ntawm lub soldering ko taw nce tin thiab ces txias solidification, lub Cheebtsam yuav tsau nyob rau hauv lub ncoo saum toj no, thiaj li mus cuag cov khoom hluav taws xob Circuit Court teeb liab kis tau tus mob.
Kev sib xyaw ntawm solder paste
solder paste muaj xws li tin hmoov hlau hais thiab flux, uas cov tin hmoov hlau hais muaj ntxhib thiab nplua cov ntsiab lus, feem ntau raws li cov ntxhib thiab nplua cov ntsiab lus 1-5, qhov loj tus naj npawb, sawv cev rau cov tin hmoov particles, qhov me, ntawm chav kawm, tus nqi yuav kim dua. Lub flux muaj resin rosin, active agent, thickener thiab hnyav, yog vim li cas yog vim li cas lub paste yog zoo ib yam li paste, yog muaj thickening tus neeg sawv cev, lub hom phiaj yog muab luam tawm nyob rau sab saum toj ntawm lub pcb ncoo tsis vau, thaum cov kuab tshuaj yog tswj lub wettability ntawm paste, tus active neeg sawv cev yog nyob rau hauv thiaj li yuav weld thaum ntxuav lub pinsld rau pcb thiab tivthaiv.
Kev siv cov tshuaj txhuam hniav
Solder paste feem ntau khaws cia rau hauv lub tub yees, qhov yuav tsum tau rov qab mus rau qhov kub thiab txias ua ntej siv, rov qab mus rau qhov kub thiab txias kuj yuav tsum tau nplawm, tej zaum nrog ib tug pas los nqa cov muab tshuaj txhuam tuaj yeem muaj qhov ntsug ntuj ntws thiab ntws mus tas li.
