Ngaba ibhodi yendibano yePCB iya kuba yingozi kumzimba womntu?

Ngaba iIndibano yePCBibhodi ibe yingozi kumzimba womntu?Abahlobo abaninzi abandwendwele le workshop baya kubuza imibuzo enjalo.Namhlanje ndiza kukunika impendulo!Kuyingozi ukusebenza ixesha elide kwindawo yebhodi yePCB.Ukungcoliswa kwendibano ye-PCB kubhekiselele kuyo nayiphi na idiphozithi yomphezulu, ukungcola, ukubandakanywa kwe-slag kunye nezibhengezo ezinciphisa imichiza, iipropati zomzimba okanye zombane ze-PCBA ukuya kumanqanaba angafanelekanga.

Iingozi zongcoliseko lwe-PCBA, ezinokukhokelela ngokuthe ngqo okanye ngokungathanga ngqo kwindibano yePCB imingcipheko enokubakho, umzekelo:

1. I-asidi ye-organic kwi-residu iya kugqwala i-PCBA;

2. Ngethuba lenkqubo yombane, i-ions kwi-residu ibangela i-electromigration ngenxa yokwahlukana okunokwenzeka phakathi kwamalungu e-solder, okubangelwa ukungaphumeleli kwe-short-circuit yemveliso;

3. Iintsalela zichaphazela umphumo wokugquma;

4. Emva kwexesha kunye nokutshintsha kobushushu bendalo, ukuqhekeka kunye nokukhwabanisa kwengubo kuya kubangela iingxaki ngokuthembeka kwemveliso.

Ukungcoliswa kwendibano ye-PCB kubhekiselele kuwo nakuphi na ukungcola komphezulu, iidiphozithi, ii-adsorbents kunye ne-slag inclusions ezinciphisa iikhemikhali, iipropati zomzimba okanye zombane ze-PCBA ukuya kumanqanaba angafanelekanga.Ukuze kuphuculwe ukuthembeka kunye nomgangatho weemveliso ze-elektroniki, kuyimfuneko ukulawula ngokungqongqo ubukho beentsalela ngexesha lokusetyenzwa kwendibano yePCB, kwaye ezi zinto zingcolileyo kufuneka zisuswe ngokupheleleyo ukuba kuyimfuneko.

Ungcoliseko lwendibano yePCB ikakhulu lubandakanya le miba ilandelayo:

1. Ungcoliseko lomphezulu we-PCB luya kubangelwa lungcoliseko okanye i-oxidation yamacandelo endibano ye-PCB kunyeiibhodi zesekethe PCB;

2. I-Soldering manual iya kuveliswa iminwe yeminwe, kwaye i-wave soldering iya kuveliswa enye i-Wave soldering trace kunye ne-Welding tray (fixture) trace.Kusenokubakho ezinye iintlobo zongcoliseko kwindibano ye-PCB yomphezulu kwiidigri ezahlukeneyo, ezifana neglue yokuplaga, iglue eshiyekileyo yetape yobushushu obuphezulu, iminwe yeminwe kunye nothuli;

3. Kwinkqubo yendibano yePCB yokuvelisa, kuyimfuneko ukusebenzisa i-solder paste, i-welding wire ye-welding.I-Flux iya kuvelisa iintsalela ngexesha lenkqubo ye-soldering, ingcolise umphezulu webhodi ye-PCB yendibano, kwaye iyona nto ingcolileyo;

4. Ungcoliseko lwe-electrostatic olubangelwa luthuli, amanzi kunye nomsi we-solvent, umphunga, i-particulate organic matter kunye namasuntswana ahlawuliweyo aqhotyoshelwe kwindibano ye-PCB emsebenzini.

Sinentembelo ekuboneleleni ngeyona ndibaniselwano ilungileyo yenkonzo yendibano ye-PCB yokujika, umgangatho, ixabiso kunye nexesha lonikezelo kwi-odolo yendibano ye-PCB yebhetshi encinci kunye ne-Mid batch Volume ye-PCB.
