Izidibanisi ezingaphelelanga kwiBhodi yeSekethe eShicileleyo-AMAZA AMAZA OKUTHENGISA IZIPHUMO

I-fillet ye-solder engaphelelanga idla ngokubonwa kwiibhodi ezisecaleni elilodwa emva kwe-wave soldering.

Kwi-Figure 1, i-lead-to-hole ratio igqithise, eyenze ukuba i-soldering ibe nzima.Kukho nobungqina be-resin smear kumda we-pad.Kunokwenzeka, nakulo yilo, ukuphucula ukusebenza kwe-solder ngokunciphisa i-angle yokuhambisa ukusuka kwi-6 ukuya kwi-4 °.Oku kunciphisa ukusebenza kwe-drain ye-wave kodwa kunokukhokelela kwisiganeko sokunciphisa.Ukunciphisa ubushushu be-wave kuye kwabonwa ukoyisa ingxaki.

Njengesikhokelo, umlinganiselo womngxuma wokukhokelela ngokuqhelekileyo yidayamitha yokukhokela kunye ne-0.010 ″, esi sisikhokelo esiqhelekileyo sofakelo oluzenzekelayo.

Umlinganiselo wokukhokelela kumngxuma apha wawugqithise kakhulu

Iifayili ze-solder ezingaphelelanga zibangelwa umlinganiselo ombi we-hole-to-lead, ii-angles zokuhambisa umnqantsa, ubushushu obugqithisileyo kunye nongcoliseko kwincam yeepads.

Umzekelo oboniswe kwi-Figure 1 ngumphumo wokutshisa kwiipadi zethusi.Ngexesha lokubhola okanye ukubethelwa, ubhedu olungaphezulu kwebhodi lwaluphambukiswa kwezinye iindawo, nto leyo eyenza kube nzima ukusoda.Kwenzeka into efanayo ukuba i-resin iqatywe kumda weepads.

Ukutshiswa kwiiphedi zobhedu kubangele esi siphene.

Yintoni ipalethi yesoda yamaza?

Iipaliti ze-wave solder yeyona ndlela inokwethenjelwa kwaye ingabizi kakhulu ye-soldering through-hole components kwiibhodi zesekethe.… Babonelela ngokhuseleko lobushushu kwiingingqi zebhodi yesekethe eprintiweyo ezinochuku kubushushu.I-wave solder fixture ibonelela ngenkxaso ye-PCB kuyo yonke inkqubo yokuthengisa amaza.

Inqaku kunye nemifanekiso evela kwi-intanethi, ukuba kukho naluphi na ulwaphulo pls kuqala uqhagamshelane nathi ukuze ucime.
