Puas yog lub rooj sib dhos PCB puas tsim kev puas tsuaj rau tib neeg lub cev?

Yuav lubPCB sib dhosboard ua teeb meem rau tib neeg lub cev?Ntau tus phooj ywg uas tau mus xyuas lub rooj cob qhia yuav nug cov lus nug no.Hnub no kuv yuav muab lus teb rau koj!Nws yog qhov tsis zoo rau kev ua haujlwm ntev hauv PCB board ib puag ncig.PCB sib dhos kab mob yog hais txog tej qhov chaw deposits, impurities, slag inclusions thiab adsorbents uas txo cov tshuaj, lub cev los yog hluav taws xob khoom ntawm PCBA mus rau unqualified theem.

Kev phom sij ntawm PCBA kev sib kis, uas tuaj yeem ncaj qha lossis ncaj qha ua rau PCB sib dhos muaj kev pheej hmoo, piv txwv li:

1. Cov organic acid nyob rau hauv cov residue yuav corrode PCBA;

2. Thaum lub sij hawm lub hwj chim-on txheej txheem, cov ions nyob rau hauv cov residue ua electromigration vim muaj peev xwm sib txawv ntawm cov solder pob qij txha, uas ua rau ib tug luv luv-circuit tsis ua hauj lwm ntawm cov khoom;

3. Cov khoom seem cuam tshuam rau cov nyhuv txheej;

4. Tom qab lub sij hawm thiab ib puag ncig kub hloov, tawg thiab warping ntawm txheej yuav ua rau muaj teeb meem nrog kev ntseeg siab ntawm cov khoom.

PCB sib dhos kab mob yog hais txog tej impurities nto, deposits, adsorbents thiab slag inclusions uas txo cov tshuaj, lub cev los yog hluav taws xob khoom ntawm PCBA mus rau unqualified theem.Txhawm rau txhim kho kev ntseeg siab thiab zoo ntawm cov khoom siv hluav taws xob, nws yog ib qho tsim nyog yuav tsum nruj me ntsis tswj qhov muaj nyob ntawm cov khoom seem thaum lub sij hawm ua PCB, thiab cov pa phem no yuav tsum raug tshem tawm tag nrho yog tias tsim nyog.

Cov pa phem ntawm PCB los ua ke feem ntau suav nrog cov hauv qab no:

1. PCB los ua ke deg pollution yuav tshwm sim los ntawm cov pa phem los yog oxidation ntawm PCB los ua ke Cheebtsam thiabPCB pawg thawj coj saib;

2. Kev tuav tes soldering yuav raug tsim cov ntiv tes, thiab yoj soldering yuav raug tsim ib co Wave soldering kab thiab Vuam tais (fixture) kab.Tej zaum yuav muaj lwm yam kab mob ntawm PCB los ua ke saum npoo ntawm qhov sib txawv, xws li ntsaws cov kua nplaum, kub kub daim kab xev nplaum nplaum, ntiv tes thiab plua plav;

3. Nyob rau hauv cov txheej txheem tsim PCB los ua ke, nws yog ib qho tsim nyog yuav tsum siv cov tshuaj txhuam hniav, vuam hlau rau vuam.Flux yuav tsim cov residues thaum lub sij hawm soldering txheej txheem, kis tus nto ntawm lub PCB los ua ke board, thiab yog lub ntsiab pa phem;

4. Electrostatic kuab paug tshwm sim los ntawm plua plav, dej thiab cov pa taws hnyav, chav ua haujlwm, cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob txuas nrog PCB sib dhos hauv chaw ua haujlwm.

Peb muaj kev ntseeg siab los muab koj qhov zoo tshaj plaws ua ke ntawm kev sib koom ua ke ntawm qhov tseem ceeb PCB sib dhos, qhov zoo, tus nqi thiab lub sijhawm khoom xa tuaj hauv koj qhov Me me batch ntim PCB los ua ke xaj thiab Mid batch Volume PCB los ua ke xaj.

Yog tias koj tab tom nrhiav ib qho zoo tagnrhoPCB los ua ke manufacturers, thov xa koj cov ntaub ntawv BOM thiab cov ntaub ntawv PCB mus rausales@pcbfuture.com.Tag nrho koj cov ntaub ntawv yog qhov tsis pub lwm tus paub.Peb yuav xa koj cov lus qhia meej nrog lub sijhawm ua haujlwm hauv 48 teev.
