PCBA soldering cua qhov, uas feem ntau hu ua huab cua npuas, feem ntau tsim thaum lub sij hawmreflowqhov cubsoldering thiabyoj solderingtshuab, yog li yuav ua li cas txhim kho qhov teeb meem ntawm PCBA soldering cua qhov?
1. Ci
PCB thiab cov khoom raug rau huab cua ntev ntev kom ci kom tsis txhob ya raws.
2. Kev tswj cov tshuaj txhuam hniav
Solder paste muaj noo noo kuj yog ib qho yooj yim los tsim porosity, tin hlaws dai. Ua ntej ntawm tag nrho cov, xaiv zoo zoo solder paste, solder paste tempering, nplawm raws li cov kev khiav hauj lwm ntawm nruj kev siv, solder paste raug rau saum huab cua rau lub sij hawm luv luv li sai tau, tom qab luam ntawv solder paste, yuav tsum tau raws sij hawm reflow soldering.
3. Kev tswj cov av noo hauv lub rhiav
Npaj saib xyuas cov av noo nyob rau hauv lub rooj cob qhia, tswj ntawm 40-60 feem pua .
4. Teem lub qhov cub kom tsim nyog qhov kub thiab txias nkhaus
Ob zaug ib hnub rau qhov ntsuas kub ntawm lub cub tawg, ua kom zoo dua qhov kub ntawm qhov cub hluav taws xob nkhaus, qhov ntsuas kub tsis tuaj yeem ceev heev.
5. Flux txau
Nyob rau hauv lub dhau yoj soldering, tus nqi ntawm flux txau tsis tuaj yeem ntau dhau, txau tsim nyog.
6. Ua kom zoo rau qhov cub kub qhov nkhaus
Qhov kub ntawm thaj tsam preheating yuav tsum tau ua kom tau raws li qhov yuav tsum tau ua, tsis txhob qis dhau, kom cov flux tuaj yeem hloov pauv tau, thiab qhov ceev ntawm lub cub tawg tsis tuaj yeem ceev heev.
Tej zaum yuav muaj ntau yam cuam tshuam rau PCBA welding npuas, uas tuaj yeem txheeb xyuas los ntawm PCB tsim, PCB av av, qhov cub kub, flux (txiav loj), saw ceev, tin yoj qhov siab, solder muaj pes tsawg leeg, thiab lwm yam. Nws yuav tsum tau debugged ob peb. lub sij hawm ua ntej nws muaj peev xwm tuaj nrog cov txheej txheem zoo dua.
1. Ua-nyob rau hauv vuam fume filtration system, zoo filtration ntawm teeb meem gases, zoo nkauj tsos thiab kev tiv thaiv ib puag ncig, ntau nyob rau hauv txoj kab nrog kev siv high-end ib puag ncig.
2. Cov kev tswj xyuas muaj cov yam ntxwv ntawm kev sib koom ua ke siab, cov lus teb raws sij hawm, tsis tshua muaj nqi, kev saib xyuas yooj yim, thiab lwm yam.
4. Cov cua kub convection, zoo heev vuam kev ua tau zoo.
5. Kev siv cov khoom siv high-performance aluminium alloy cua sov phaj hloov cov cua sov raj, ob qho tib si txuag hluav taws xob thiab txuag hluav taws xob, piv nrog cov reflow qhov cub zoo sib xws ntawm kev ua lag luam, qhov sib txawv ntawm qhov kub ntawm sab nraud yog txo qis.
6. Kev tsim hluav taws xob tiv thaiv hluav taws xob, lub plhaub kub tuaj yeem tswj tau zoo.
