Los ntawm peb cov kev coj ua haujlwm tshaj lij thiab kev mob siab rau kev ua haujlwm, peb tau lees paub los ntawm ntau lub tuam txhab tsim khoom hauv kev lag luam.
Peb tshwj xeeb hauv kev tsim cov PCBs kev lag luam ntau txheej thiab muab cov kev pabcuam PCBA ib zaug xwb. Peb cov txheej txheem pib nrog cov ntaub ntawv lossis Gerber xa los ntawm tus neeg siv. Tom qab tau txais cov ntaub ntawv no, peb cov engineers tshuaj xyuas thiab tsim cov txheej txheem tsim khoom los tsim cov laug cam PCB thiab cov khoom PCBA rau kev tswj hwm kev lag luam siv cov thev naus laus zis sib txawv. RICHPCBA tuaj yeem ua tau raws li cov kev xav tau ntawm cov neeg siv khoom rau cov haujlwm yooj yim mus rau cov haujlwm nyuaj, cov khoom me me mus rau cov khoom loj PCB sib dhos, thiab cov lag luam pib tshiab mus rau cov tuam txhab loj hauv kev lag luam. Peb pab neeg ntawm cov kws tshaj lij ua cov haujlwm los ntawm 1V1 cov thawj coj haujlwm, txhawb nqa los ntawm kev yuav khoom, kev tsim kho, kev tsim khoom, thiab cov pab pawg tswj xyuas zoo.

Cov Yam Ntxim Saib ntawm Kev Tsim PCB Hauv Kev Lag Luam
Kev Tsim Khoom
Qhov kev tso cov khoom sib xyaw rau ntawm lub rooj tsavxwm yog qhov tseem ceeb uas yuav tsum xav txog thaum tsim cov PCB boards tswj kev lag luam. Kev tso cov khoom tsis raug tuaj yeem cuam tshuam rau kev ntseeg siab thiab kev ua tau zoo ntawm cov khoom kawg. Thaum lub sijhawm tsim PCB board, yuav tsum tau ceev faj tshwj xeeb kom ntseeg tau tias cov khoom sib xyaw tau teeb tsa rau ntawm lub rooj tsavxwm nrog qhov tsawg kawg yog 100 mils qhov chaw ntawm ntug ntawm lub rooj tsavxwm thiab cov khoom sib dhos. Qhov no ua kom ntseeg tau tias qhov loj ntawm lub rooj tsavxwm thiab cov qhov sib dhos yog sib xws.
EMI thiab RFI
Hauv kev siv hauv kev lag luam, nws yog ib qho tseem ceeb kom txo qis cov teebmeem ntawm Electromagnetic Interference (EMI) thiab Radio Frequency Interference (RFI), uas tuaj yeem ua rau muaj suab nrov thiab cuam tshuam kev ua haujlwm ntawm PCBA. Txog qhov kawg no, Rich PCBA muaj ntau txoj hauv kev:
Kev teeb tsa ntawm pawg thawj coj saib xyuas: Yuav kom txo tau qhov kev pheej hmoo ntawm kev sib txuas suab nrov, cais cov circuits siab zaus ntawm cov circuits qis zaus thiab khaws cov cim qhia kom deb ntawm lub zog thiab cov dav hlau hauv av. Cov cim qhia yuav tsum luv li sai tau, thaum lub zog thiab cov dav hlau hauv av yuav tsum loj li sai tau thiab xa nrog cov qhov sib txuas qis inductance kom txo qhov impedance ntawm lub network fais fab.
Cov khoom lim dej: Ntxiv cov khoom lim xws li capacitors thiab inductors rau cov kab hluav taws xob thiab cov kab teeb liab kom lim cov suab nrov tsis xav tau.
Cov Txheej Txheem Grounding thiab Shielding: Muab cov khoom rhiab heev tso rau hauv Faraday cages kom thaiv EMI thiab RFI.
Kev Xaiv Cheebtsam: Xaiv cov khoom siv hauv lub rooj tsavxwm uas muaj kev sib txuas av thiab kev tiv thaiv zoo. Siv cov xov hlau tiv thaiv los txuas lub rooj tsavxwm rau cov khoom siv sab nraud kom tiv thaiv kev sib txuas lus tsis xav tau.
Cov Khoom Siv PCB Tswj Kev Lag Luam
Kev xaiv cov ntaub ntawv rau kev tsim PCB yog qhov tseem ceeb heev thiab yuav tsum ua raws li qhov chaw ua haujlwm tshwj xeeb. Cov ntaub ntawv rau PCBs siv hauv kev lag luam yuav tsum muaj peev xwm tiv taus cov xwm txheej hnyav, xws li kub siab, hluav taws xob siab, av noo, kev co, thiab kev raug tshuaj lom neeg. Qee cov ntaub ntawv siv feem ntau rau PCBs kev lag luam yog:
● Polyimide: Cov khoom siv ua tau zoo no tuaj yeem tiv taus qhov kub thiab txias txog li 400 ° C thiab feem ntau siv rau hauv kev tsav dav hlau, tub rog, thiab kev tswj hwm kev lag luam kub siab.
● Cov Khoom Uas Ua Los Ntawm Av nplaum: Ib lub PCB ceramic yog ua los ntawm cov khoom siv ceramic thiab cov hlau me me. Lawv muaj cov thermal conductivity zoo heev thiab tuaj yeem tswj tau qhov kub thiab txias siab thiab cov tshuaj lom neeg hnyav. Lawv feem ntau siv rau hauv cov khoom siv hluav taws xob thiab cov ntawv thov zaus siab.
● PTFE: PTFE los yog polytetrafluoroethylene yog ib qho fluoropolymer uas muaj cov khoom siv hluav taws xob zoo heev uas tuaj yeem tiv taus qhov kub siab txog li 260 ° C. Nws feem ntau siv rau hauv cov ntawv thov high-frequency thiab microwave, nrog rau cov chaw muaj tshuaj lom neeg hnyav.
● FR-4: Cov khoom sib xyaw ua ke no ua los ntawm cov ntaub fiberglass thiab epoxy resin yog cov khoom siv feem ntau siv rau cov PCBs dav dav, suav nrog kev lag luam. FR4 PCB muaj cov khoom rwb thaiv hluav taws xob zoo thiab tuaj yeem tiv taus qhov kub thiab txias siab thiab tshuaj lom neeg.
