1. ua ntej ntau lawm, thaum tusham muab tshuaj tov khoomyog siv los do cov muab tshuaj txhuam kom ua rau nws txawm, tus neeg teb xov tooj yuav tsum tsis tu ncua kuaj cov cam muab tshuaj viscosity nrog viscosity tester lossis qhov ntsuas tau zoo.
2.Nyob rau hauv cov txheej txheem ntau lawm, kev luam ntawv ua haujlwm ntawm kev muab tshuaj zoo dua yuav tsum yog 100% kev tshuaj xyuas, thiab cov ntsiab lus tseem ceeb yuav tsum yog tias cov tshuaj txhuam cov duab ua tiav tiav, seb qhov tuab puas zoo ib yam, thiab seb puas muaj ham muab tshuaj txhuam taw qhov tshwm sim.
3. tom qab qhov kev sim luam ntawv los yog luam ntawv tsis ua tiav, tus muab tshuaj txhuam ntawm lub tshuab luam ntawv yuav tsum ua kom huv si thiab ziab nrog ibPCB tshuab ntxhua khaub ncawstiv thaiv ham ham khoom tawm hauv qhov tshwm sim tom qab reflow vim muaj ham muab tshuaj seem ntawm lub board thaum siv tas.
4. cov ham muab tshuaj yuav tsum nruj siv nyob rau hauv lub sij hawm siv tau. Cov tshuaj nplaum tsis tso tawm yuav tsum muab tso rau hauv lub tub yees rau hauv cov hnub ib txwm thiab yuav tsum khaws cia hauv chav tsev ntev tshaj 6 teev ua ntej siv.
5. tom qab cov phaj luam ntawv ua ntej lossis cov khoom siv raug kho kom haum, lub plhaw ham thickness tester yuav tsum siv los ntsuas qhov tuab luam ntawv ntawm ham muab tshuaj. Cov ntawv ntsuas yuav tsum xaiv 5 qhov chaw ntawm PCB qhov chaw ntsuas, xws li sab saud thiab qis dua, sab laug thiab sab xis, thiab nruab nrab, thiab tus nqi yuav tsum sau tseg.
6.Cov qauv tsim cov qauv raws li cov txheej txheem yuav tsum tau tom qab kev ua haujlwm ntawm kev ua haujlwm tiav.
