Uyenza njani iprofayile yereflow?

Ngokwengcebiso yombutho we-IPC, i-generic Pb-freereflow solderiprofayile iboniswe ngezantsi.Ummandla OLULUHLAZA luluhlu olwamkelekileyo lwenkqubo yokubuyisela kwakhona.Ngaba ithetha ukuba yonke indawo kule ndawo LUHLAZA kufuneka ilingane nesicelo sakho sebhodi yokubuyisela kwakhona?Impendulo ngokupheleleyo nguHAYI!

Umthamo we-thermal we-PCB wahlukile ngokohlobo lwezinto eziphathekayo, ubukhulu, ubunzima bobhedu kunye nokumila kwebhodi.Kwahluke kakhulu xa amalungu afunxa ubushushu ukuze afudumale.Amalungu amakhulu anokufuna ixesha elininzi lokufudumeza kunamancinci.Ke, kuya kufuneka uhlalutye ibhodi yakho ekujoliswe kuyo kuqala ngaphambi kokudala iprofayile yokubuyisela kwakhona.

1. Yenza iprofayile yereflow enenyani.

Iprofayile ye-reflow enenyani isekwe kwithiyori ye-soldering, iprofayili ecetyiswayo ye-solder evela kumenzi we-solder paste, ubukhulu, ubukhulu, ubunzima be-cooper, iileya zebhodi kunye nobukhulu, kunye nobuninzi bezinto.

1. Hlaziya ibhodi kwaye ulinganise iprofayili yexesha langempela lobushushu ngaxeshanye.
2. Jonga umgangatho odibeneyo we-solder, i-PCB kunye nesimo secandelo.
3. Ukutshisa-kwibhodi yovavanyo kunye nokutshatyalaliswa kwe-thermal kunye nokutshatyalaliswa komatshini ukujonga ukuthembeka kwebhodi.
4. Thelekisa idatha yobushushu yexesha lokwenyani kunye neprofayile yenyani.
5. Lungisa ukuseta iparameter kwaye uvavanye amaxesha amaninzi ukufumana umda ophezulu kunye nomgca osezantsi weprofayile yokubuyisela ixesha lokwenyani.
6. Gcina iiparameters ezilungiselelweyo ngokweebhodi ekujoliswe kuzo ngokuphinda uqukunjelwe kucacisiwe.
