Raws li ib feem tseem ceeb ntawm tag nrho cov khoom siv hluav taws xob, cov thev naus laus zis nrov tshaj plaws hauv ntiaj teb xav kom ua tiav PCB tsim. Txawm li cas los xij, cov txheej txheem nws tus kheej qee zaum tsis muaj dab tsi. ilv thiab complex, yuam kev feem ntau tshwm sim nyob rau hauv cov txheej txheem tsim PCB. Vim qhov kev ncua sij hawm ntau lawm los ntawm Circuit Board reflow, cov hauv qab no yog peb yam PCB yuam kev uas yuav tsum tau muab sau tseg kom tsis txhob ua haujlwm yuam kev.

1.) Kev tsaws hom

Txawm hais tias feem ntau PCB tsim software suav nrog General Electric cov tsev qiv ntawv, lawv cov cim schematic thiab cov qauv tsaws, qee qhov Circuit Court boards yuav xav kom cov neeg tsim qauv kos lawv tus kheej. Yog tias qhov yuam kev tsawg dua li ib nrab millimeter, tus engineer yuav tsum nruj heev kom ntseeg tau qhov sib nrug ntawm cov ntaub qhwv. Kev ua yuam kev thaum lub sijhawm no ntawm kev tsim khoom yuav ua rau vuam nyuaj lossis ua tsis tau. Qhov tsim nyog rov ua dua yuav ua rau raug nqi qeeb.

2.) Siv qhov muag tsis pom / faus vias

Hauv kev ua lag luam ntawm cov khoom siv uas tau siv los siv IoT niaj hnub no, cov khoom me me thiab cov khoom me me txuas ntxiv ua rau muaj kev cuam tshuam loj tshaj plaws. Thaum cov khoom siv me me xav tau cov PCBs me, ntau tus engineers xaiv siv qhov muag tsis pom vias thiab faus vias los txo cov hneev taw ntawm lub rooj tsav xwm hauv Circuit Court kom txuas cov txheej sab hauv thiab sab nraud. Txawm hais tias los ntawm lub qhov tuaj yeem txo qhov chaw ntawm PCB, nws txo qhov chaw thaiv, thiab raws li tus naj npawb ntawm cov khoom ntxiv, nws yuav nyuaj, uas ua rau qee cov laug cam kim thiab tsis tuaj yeem tsim khoom.

3.) Cov kab dav dav

Txhawm rau ua kom lub rooj tsavxwm me me thiab compact, tus engineer lub hom phiaj yog ua kom cov kab nrib nqaim li sai tau. Kev txiav txim siab PCB kab dav dav suav nrog ntau qhov sib txawv, uas ua rau nws nyuaj, yog li nws yuav tsum nkag siab tias yuav tsum muaj pes tsawg milliamps. Feem ntau, qhov tsawg kawg nkaus qhov dav yuav tsum tsis txaus. Peb pom zoo kom siv lub laij lej dav los txiav txim siab qhov tsim nyog thickness thiab xyuas kom meej tus qauv tsim.
