Ingabe ibhodi lokuhlanganisa le-PCB lizoba yingozi emzimbeni womuntu?

Ingabe iUkuhlanganiswa kwe-PCBibhodi kube yingozi emzimbeni womuntu?Abangane abaningi abavakashele i-workshop bazobuza imibuzo enjalo.Namuhla ngizokunikeza impendulo!Kuyingozi ukusebenza isikhathi eside endaweni yebhodi le-PCB.Ukungcoliswa komhlangano we-PCB kubhekise kunoma yikuphi ukudiphozithi okungaphezulu, ukungcola, ukufakwa kwe-slag kanye nezikhangisi ezehlisa amakhemikhali, izakhiwo zomzimba noma zikagesi ze-PCBA zibe amazinga angafaneleki.

Izingozi zokungcola kwe-PCBA, ezingase ziholele ngokuqondile noma ngokungaqondile ekuhlanganiseni kwe-PCB ubungozi obungaba khona , isibonelo:

1. I-asidi ephilayo esele izogqwalisa i-PCBA;

2. Phakathi nenqubo yokuvula amandla, ama-ion asele abangela ukufuduka kwe-electromigration ngenxa yomehluko ongaba khona phakathi kwamalunga e-solder, okuholela ekuhlulekeni kwesiyingi esifushane somkhiqizo;

3. Izinsalela zithinta umphumela wokugcoba;

4. Ngemva kwesikhathi kanye noshintsho lokushisa kwemvelo, ukuqhekeka kanye warping of enamathela kuzodala izinkinga ukwethembeka umkhiqizo.

Ukungcoliswa komhlangano we-PCB kubhekise kunoma yikuphi ukungcola okungaphezulu, amadiphozithi, ama-adsorbent kanye nokufakwa kwe-slag okwehlisa amakhemikhali, izakhiwo zomzimba noma zikagesi ze-PCBA zibe amazinga angafaneleki.Ukuze kuthuthukiswe ukwethembeka kanye nekhwalithi yemikhiqizo ye-elekthronikhi, kuyadingeka ukulawula ngokuqinile ukuba khona kwezinsalela ngesikhathi sokucubungula umhlangano we-PCB, futhi lezi zinto ezingcolile kufanele zisuswe ngokuphelele uma kunesidingo.

Ukungcoliswa kokuhlanganiswa kwe-PCB kufaka phakathi izici ezilandelayo:

1. Ukungcoliswa kwendawo yomhlangano we-PCB kuzobangelwa ukungcoliswa noma ukukhishwa kwe-oxidation yezingxenye zomhlangano we-PCB kanyeAmabhodi wesekethe we-PCB;

2. Kuzokhiqizwa izigxivizo zeminwe ezenziwe ngezandla, futhi i-wave soldering izokhiqizwa umkhondo we-Wave soldering trace kanye nethreyi ye-Welding (i-fixture).Kungase kube nezinye izinhlobo zokungcola endaweni yomhlangano we-PCB ngamazinga ahlukahlukene, njengokuxhuma iglue, insalela ye-tape ye-tape yokushisa ephezulu, izigxivizo zeminwe nothuli;

3. Enqubweni yokuhlanganisa ye-PCB yokukhiqiza, kuyadingeka ukusebenzisa i-solder paste, i-welding wire yokushisela.I-Flux izokhiqiza izinsalela ngesikhathi senqubo yokuhlanganisa, ingcolise ubuso bebhodi lomhlangano le-PCB, futhi iyona engcolisa kakhulu;

4. Ukungcoliswa kwe-electrostatic okubangelwa uthuli, amanzi kanye nentuthu encibilikayo, umusi, izinhlayiya ze-organic kanye nezinhlayiya ezikhokhiswayo ezinamathiselwe ekuhlanganisweni kwe-PCB emsebenzini.

Siyazethemba ekukunikezeni inhlanganisela engcono kakhulu yesevisi yokuhlanganisa ye-PCB yokhiye wokuvula, ikhwalithi, intengo kanye nesikhathi sokulethwa ku-oda lakho leqoqo le-PCB yevolumu yeqoqo elincane kanye ne-oda lokuhlanganisa le-Mid Batch Volume PCB.
