PCBA ibhodi yesekethe welding idiskhi ingxaki emnyama yinto eqhelekileyo ngakumbi ibhodi yesekethe embi, ekhokelela kwi-PCBA welding disc emnyama ngenxa yezizathu ezininzi, kodwa idla ngokubangelwa zezi zizathu zilandelayo:

I-1, i-pad oxidation: Ukuba i-pad ye-PCBA ibonakaliswe kumswakama ixesha elide, iya kubangela ukuba umphezulu we-pad udibanise, yenze ifilimu ye-oxide phezu komphezulu we-pad, okukhokelela kumnyama, ngoko ke, xa ugcina i-PCBA, ingqalelo kufuneka ihlawulwe ukugcina okusingqongileyo yomile, kwaye kwangaxeshanye, PCBA kufuneka vacuumed kwangethuba ukuphepha ukuba sesichengeni yayo ixesha elide emoyeni!

I-2, iingxaki zenkqubo ye-welding: kwi-welding welding okanye i-wave soldering, ukuba ubushushu be-welding buphezulu kakhulu okanye ixesha le-welding lide kakhulu, oko kuya kukhokelela kwi-oxidation ye-welding pad black phenomenon, le mpendulo idla ngokuba ngenxa ye-welding. iqondo lobushushu lidlula iqondo lobushushu elicetyiswayo kwi-solder, okukhokelela kwinkqubo ye-oxidation ekhawulezileyo, ngoko ke kwinkqubo ye-welding kufuneka ihambelane nemigaqo yokusebenza ye-welding!

I-3, ingxaki ye-solder: i-solder ngokubanzi ibhekisela kwi-solder paste, i-tin, ikhwalithi ye-solder ilungile okanye imbi, ukuba ukusetyenziswa kwe-solder esemgangathweni, kuya kwenza ukuba i-solder kwizinto ezinobungozi kunye nokungcola kukhululwe, kubangele iphedi emnyama, ngoko, ekukhetheni i-solder, kufuneka sikuphephe ukusetyenziswa kwe-solder ephantsi!

I-4, iingxaki zokucoca: Ngokuqhelekileyo, kwimeko yokusetyenziswa kwe-flux iyadingeka ukucoca ibhodi, ukwenzela ukuba kususwe i-residu ye-flux kwi-pad, kwaye ukuba i-residu ye-flux ayisuswanga ngokupheleleyo, ke le mibhobho eseleyo inokunciphisa. okanye i-carbonize kwiqondo lokushisa eliphezulu, ukwenzela ukuba i-pad ibonakala imnyama. Ngoko ke, ukucoca ngexesha elifanelekileyo emva kwe-welding kubaluleke kakhulu!

I-5, iingxaki zecandelo: ukuba umgangatho wamacandelo e-elektroniki awulungile, okanye izinto ze-pin yecandelo azifanelekanga, kunokukhokelela kwi-disc ye-welding emnyama, ngoko ke, xa sikhetha amacandelo e-elektroniki, kufuneka sikhethe umgangatho olungileyo. amacandelo okuqinisekisa ukuba umgangatho wokugquma kunye nezixhobo zepini zamacandelo zifanelekile.

Oku ngasentla sesona sizathu siphambili PCBA welding itreyi emnyama, kwaye ngokwezizathu ezahlukeneyo, sinako kwakhona ukukhetha amanyathelo okuphucula ehambelanayo, ukuze kuncitshiswe ngempumelelo ingxaki PCBA welding itreyi emnyama, ukuphucula umgangatho weemveliso!
