PCBA welding processing ngokuqhelekileyo ineemfuno ezininzi kwibhodi PCB, leyo kufuneka ukuhlangabezana neemfuno welding. Ke kutheni le nto inkqubo yokuwelda ifuna iimfuno ezininzi kangaka zeebhodi zesekethe? Inyaniso ibonise ukuba kuya kubakho iinkqubo ezininzi ezikhethekileyo kwinkqubo ye-PCBA welding, kwaye ukusetyenziswa kweenkqubo ezizodwa kuya kuzisa iimfuno kwi-PCB.

Ukuba ibhodi PCB iingxaki, iya kwandisa ubunzima PCBA ukuwelda inkqubo, yaye ekugqibeleni kunokukhokelela iziphene ukuwelda, iibhodi ezingafanelekanga, njl Ngoko ke, ukuze kuqinisekiswe ukugqitywa olugudileyo iinkqubo ezikhethekileyo kunye lula PCBA welding processing, PCB board. kufuneka ihlangabezane neemfuno zokwenziwa ngokobungakanani kunye nomgama wephedi.

Okulandelayo, ndiya kwazisa iimfuno PCBA welding processing kwibhodi PCB.
Iimfuno PCBA welding processing kwibhodi PCB
1. Ubungakanani bePCB
Ububanzi be-PCB (kubandakanywa nomphetho webhodi yesekethe) kufuneka bube bukhulu kune-50mm kwaye bungaphantsi kwe-460mm, kwaye ubude be-PCB (kubandakanywa nomphetho webhodi yesekethe) kufuneka bube bukhulu kune-50mm. Ukuba ubungakanani buncinci kakhulu, kufuneka wenziwe kwiipaneli.
2. PCB edge ububanzi
I-Plate edge ububanzi> 5mm, isithuba seplate <8mm, umgama phakathi kweplate yesiseko kunye ne-plate edge> 5mm.
3. PCB ukugoba
Ukugoba phezulu: <1.2mm, ukugoba phantsi: <0.5mm, ukuguqulwa kwe-PCB: ubude obuphezulu be-deformation ÷ ubude bediagonal <0.25.
4. Indawo yamanqaku ePCB
Phawula imilo: isangqa esisemgangathweni, isikwere kunye nonxantathu;
Ubungakanani bophawu: 0.8 ~ 1.5mm;
Iimathiriyeli zokumakisha: iiplating zegolide, iipleyiti zetin, ikopolo kunye neplatinam;
Iimfuno zomphezulu kaMarko: umphezulu usicaba, ugudile, awunayo i-oxidation kunye nokungcola;
Iimfuno ezijikeleze uphawu: akuyi kubakho miqobo efana neoli eluhlaza ngokucacileyo eyahlukileyo kumbala wophawu ngaphakathi kwe-1mm ngeenxa zonke;
Indawo yokumakisha: ngaphezu kwe-3mm ukusuka kwincam yepleyiti, kwaye akuyi kubakho ngomngxuma, indawo yovavanyo kunye namanye amanqaku ngaphakathi kwe-5mm.
5. PCB iphedi
Akukho mingxunya kwiipads zamacandelo e-SMD. Ukuba kukho umngxuma, i-solder paste iya kumpompoza emngxunyeni, okukhokelela ekunciphiseni kwetoti kwisixhobo, okanye i-tin igeleze iye kwelinye icala, okukhokelela kumgangatho webhodi ongalinganiyo kwaye ayikwazi ukuprinta i-solder paste.

Kuyilo PCB kunye nemveliso, kuyimfuneko ukuqonda ezinye PCB welding inkqubo ulwazi ukwenzela ukwenza iimveliso ezifanelekileyo kwimveliso. Okokuqala, ukuqonda iimfuno zeplanti yokulungiswa kunokwenza inkqubo elandelayo yokuvelisa igudiswe ngakumbi kwaye ithintele ingxaki engeyomfuneko.
Oku kungasentla sisingeniso kwiimfuno zePCBA welding processing kwiibhodi zePCB. Ndiyathemba ukuba inokukunceda kwaye ufuna ukwazi ngakumbi malunga ne-PCBA yolwazi lwe-welding processing.
