Lub tshuab kuaj tshuaj txhuam hniav, tseem hu ua lub tshuab luam ntawv stencil lossis cov tshuaj ntsuam xyuas tshuaj ntsuam xyuas (SPI), yog ib qho cuab yeej siv los ntsuas qhov zoo thiab qhov tseeb ntawm cov khoom siv tshuaj pleev xim rau ntawm cov ntawv luam tawm Circuit Board (PCBs) thaum lub sijhawm tsim khoom.
Cov tshuab no ua haujlwm hauv qab no:
Kev tshuaj xyuas ntawm cov khoom siv tshuaj pleev ib ce: Lub tshuab ntsuas thiab tshuaj xyuas qhov ntim ntawm cov tshuaj muab tshuaj tso rau ntawm PCB.Qhov no ua kom ntseeg tau tias qhov tseeb ntawm cov tshuaj txhuam hniav raug siv rau kev ua kom zoo thiab tshem tawm cov teeb meem xws li cov khoom siv los yog cov khoom siv tsis txaus.
Kev txheeb xyuas ntawm kev sib xyaw ua ke ntawm solder paste: Lub tshuab tshawb xyuas qhov kev sib tw ntawm cov nplaum nplaum nrog kev hwm rau PCB pads.Nws kuaj xyuas qhov tsis zoo lossis kev sib txawv, kom ntseeg tau tias cov tshuaj txhuam hniav raug muab tso rau ntawm qhov chaw npaj.
Kev kuaj xyuas qhov tsis xws luag: Lub tshuab tshuaj ntsuam xyuas lub tshuab txheeb xyuas cov teeb meem xws li smearing, bridging, lossis misshapen solder deposits.Nws tuaj yeem kuaj pom cov teeb meem xws li cov tshuaj nplaum ntau dhau lossis tsis txaus, kev tso nyiaj tsis sib xws, lossis cov qauv siv tsis raug.
Kev ntsuas qhov siab ntawm solder paste qhov siab: Lub tshuab ntsuas qhov siab lossis thickness ntawm solder paste deposits.Qhov no yuav pab kom muaj kev sib haum xeeb hauv kev sib koom ua ke thiab tiv thaiv cov teeb meem xws li tombstoning lossis solder joint voids.
Kev txheeb xyuas kev txheeb xyuas thiab kev tshaj tawm: Solder paste kuaj tshuab feem ntau muab kev txheeb xyuas kev txheeb xyuas thiab tshaj tawm cov yam ntxwv, tso cai rau cov tuam txhab lag luam taug qab thiab txheeb xyuas qhov zoo ntawm cov khoom siv tshuaj yaj yeeb thaum lub sijhawm.Cov ntaub ntawv no pab txhim kho cov txheej txheem thiab pab ua kom tau raws li cov qauv zoo.
Zuag qhia tag nrho, solder paste kuaj cov cav tov pab txhim kho kev ntseeg tau thiab zoo ntawm cov khoom siv hauv PCB los ntawm kev ua kom paub tseeb cov ntaub ntawv muab tshuaj txhuam thiab kuaj xyuas qhov tsis xws luag ua ntej ua haujlwm ntxiv, xws li reflow soldering lossis yoj soldering.Cov tshuab no ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom lag luam thiab txo qhov muaj feem cuam tshuam txog cov teeb meem hauv cov khoom siv hluav taws xob.
