Hauv kev tsim ntawm PCB, ntau tus phooj ywg tsis paub txaus txog txheej txheej hauv PCB, tshwj xeeb yog cov novice, lub luag haujlwm ntawm txhua txheej tsis meej. Lub sijhawm no, cia saib lub AlTIumDesigner daim duab kos duab, qhov sib txawv ntawm txhua txheej.

1. Teeb liab txheej

Cov teeb liab txheej tau muab faib ua TopLayer (TopLayer) thiab BottomLayer (BottomLayer), uas muaj kev sib txuas hluav taws xob thiab tuaj yeem tso cov khoom sib txuas thiab cov kab hluav taws xob.

2. Cov neeg kho tshuab txheej

Neeg kho tshuab yog lub ntsiab lus ntawm qhov pom ntawm tag nrho PCB pawg thawj coj saib. Qhov tseem ceeb ntawm “Mechanical” txhais tau tias nws tsis muaj cov khoom siv hluav taws xob, yog li nws tuaj yeem siv nyab xeeb rau kev kos duab, kos duab Mechanical qhov ntev, tso cov ntawv, thiab ntxiv rau, yam tsis muaj kev txhawj xeeb txog kev hloov pauv rau cov khoom siv hluav taws xob ntawm pawg thawj coj. Qhov siab tshaj ntawm 16 txheej txheej txheej tuaj yeem xaiv tau.

3. Screen luam ntawv txheej

Sab saum toj Overlay thiab Hauv Qab Overlay tau siv los txheeb xyuas Cov Cim saum toj thiab hauv qab cov ntawv luam tawm. Lawv yog cov ntawv cim luam tawm rau Sab saum toj ntawm txheej txheej tiv thaiv kab mob, xws li cov npe tivthaiv, cov cim tivthaiv, tus lej tivthaiv, thiab cov cai, txhawm rau pab txhawb kev sib txuas hauv Circuit Court thiab kuaj xyuas qhov yuam kev.

4. Tin txheej txheej

Cov txheej txheem muab tshuaj txhuam nrog rau txheej Paste Top thiab Txheej Paste Hauv Qab, uas yog hais txog saum npoo Paste ncoo uas peb tuaj yeem pom sab nraud, uas yog, ib feem uas yuav tsum tau txheej nrog cov tshuaj txhuam ua ntej welding. Yog li txheej txheej no tseem muaj txiaj ntsig hauv huab cua kub sib luag ntawm lub ncoo thiab ua vuam hlau ntxaij.

5. Vuam tiv taus txheej

Cov txheej txheej txheej kuj tseem raug xa mus ua “windowing-out,” suav nrog TopSolder thiab BottomSolder, uas ua lub luag haujlwm tsis zoo rau kev muab tshuaj txhuam txhuam thiab xa mus rau txheej kom npog cov roj ntsuab. Cov txheej no tsis muaj kab laug sab kom tiv thaiv kev luv luv ntawm cov laug ntau dhau ntawm cov pob qij txha nyob ib sab thaum lub sijhawm siv vuam. Cov txheej txheem tiv thaiv txheej txheem npog cov kab xev tooj liab thiab tiv thaiv cov yeeb yaj kiab tooj liab los ntawm oxidizing sai heev hauv huab cua, tab sis txoj haujlwm tau muab tso tseg ib sab ntawm qhov sib koom ua ke thiab tsis npog qhov sib koom ua ke.

Cov tooj liab txheej lossis cov hlua yog lub npog ntsuab ntsuab, yog tias peb sib xws hauv cov txheej txheej txheej txheej, yuav tiv thaiv cov roj ntsuab los npog, yuav nthuav tawm tooj liab.

6. Drilling txheej

Cov txheej txheem laum suav nrog DrillGride thiab DrillDrawing. Cov txheej txheem laum yog siv los muab cov ntaub ntawv hais txog kev siv lub qhov nyob hauv cov txheej txheem tsim khoom hauv pawg thawj coj saib xyuas (xws li cov ntaub qhwv, uas yuav tsum tau ua kom dhau los ntawm qhov).

7, txwv tsis pub thaiv txheej txheej txwv tsis pub thaiv txheej txheej (KeepOutLayer) siv los txheeb xyuas thaj tsam ntawm txheej txheej thaiv, tom qab txheeb xyuas qhov txwv tsis pub thaiv txheej txheej, yav tom ntej cov txheej txheem txheej txheem, nrog cov yam ntxwv hluav taws xob tuaj yeem tsis pub dhau ciam teb txwv txoj hlua thaiv.

8. Ntau txheej

Cov ntaub qhwv thiab nkag mus rau ntawm lub rooj tsav xwm hluav taws xob yuav tsum nkag mus rau tag nrho lub rooj tsav xwm hauv Circuit Court thiab tsim hluav taws xob sib txuas nrog cov txheej txheem sib nqus sib nqus, yog li cov txheej txheem tshwj xeeb teeb tsa txheej txheej tsis paub daws teeb-ntau txheej. Feem ntau, cov pawm thiab qhov tau teem rau ntau txheej, thiab yog tias txheej no raug kaw, cov pawm thiab qhov yuav tsis pom.
